Technical Field

[0001] The invention relates to the technical field of chemical analysis, in particular to a method for detecting the solid content of an emulsion. Background Art

[0002] At present, the solid content of emulsion is one of the important indicators of emulsion quality control. It reflects the content of non-volatile matter in the emulsion and directly affects the use effect and stability of the emulsion. The solid content not only affects the concentration and formula stability of the emulsion, but is also closely related to its performance in practical applications. Therefore, accurate determination of the solid content of the emulsion is of great significance for the quality control and performance evaluation of emulsion products.

[0003] For example, the invention patent with announcement number CN101644678B announces a method for detecting the content of titanium dioxide in emulsion or milk powder, including the following steps: 1) preparing a standard curve of titanium standard solution, 2) sampling, 3) sample processing, 4) testing the sample and 5) comparing the sample test results with the standard curve to obtain the titanium dioxide content in the sample. The detection equipment is an inductively coupled plasma emission spectrometer with an instrument detection limit of 0.0012 μg / mL. Within the linear range of the element, the correlation coefficient r is above 0.999 and the recovery rate is 93.2% to 99%.

[0004] For example, the invention patent with publication number CN118566335A discloses a method and device for rapid detection of the solid content of a sizing agent emulsion for glass fiber. First, a portion of the sample is taken from the prepared sizing agent emulsion, and the sample temperature is adjusted to 20°C and the pH value is 7. The transmission speed of the sound wave in the sizing agent emulsion sample is measured to be V0=L / t; then VT=V0+γ(T-20) is calculated according to the temperature compensation formula; then Vph=VT+β(pH-7) is calculated according to the pH compensation formula, and finally the solid content value of the sizing agent emulsion is calculated to be Y=YT*YpH*Vph / V0.

[0015] As a further method, the densitometer is judged whether an early warning prompt is needed based on the accurate comparison result of the densitometer test, and the specific judgment process is: If the density meter test precision index is greater than or equal to the density meter test precision index limit value preset in the content detection database, the density meter test precision comparison result is recorded as the density meter test first precision comparison result.

[0016] If the density meter test precision index is less than the density meter test precision index limit value preset in the content detection database, the density meter test precision comparison result is recorded as the density meter test second precision comparison result.

[0017] If the accurate comparison result of the density meter test is the second accurate comparison result of the density meter test, an early warning prompt is required for the density meter.

[0028] As a further method, the emulsion evaporation comparison result is used to determine whether to continue to perform the same drying process on the remaining emulsion samples to be tested to obtain the weight of each solid sample. The specific determination process is: If the emulsion evaporation index is greater than or equal to the emulsion evaporation index limit value preset in the content detection database, the emulsion evaporation comparison result is recorded as the first evaporation comparison result.

[0029] If the emulsion evaporation index is less than the emulsion evaporation index limit value preset in the content detection database, the emulsion evaporation comparison result is recorded as the second evaporation comparison result.

[0030] If the emulsion evaporation comparison result is the first evaporation comparison result, the same drying process is continued for the remaining emulsion samples to be tested to obtain the weight of each solid sample.

[0031] If the emulsion evaporation comparison result is the second evaporation comparison result, it is necessary to give an early warning prompt to the heating device.

[0032] As a further method, the final determination of whether it is necessary to issue an early warning prompt for the corresponding function between the preset density value and the detected solid content is based on the solid content deviation comparison result. The specific determination process is: If the average deviation value of the solid content of the emulsion sample to be tested is less than or equal to the solid content deviation threshold value of the emulsion sample to be tested preset in the content detection database, the solid content deviation comparison result is recorded as the first solid content deviation comparison result. If the average deviation value of the solid content of the emulsion sample to be tested is greater than the solid content deviation threshold value of the emulsion sample to be tested preset in the content detection database, the solid content deviation comparison result is recorded as the second solid content deviation comparison result.

[0033] If the solid content deviation comparison result is the solid content second deviation comparison result, it is necessary to give an early warning prompt for the corresponding function between the preset density value and the detected solid content.

[0034] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention obtains environmental data of the area to which the densitometer belongs and the test status data of the densitometer, and comprehensively analyzes to obtain the test accuracy index of the densitometer, so as to evaluate the test accuracy of the densitometer in real time and ensure that the influence of the test environment and instrument status on the test results is fully considered. When the test accuracy index of the densitometer is lower than the preset limit value, an early warning prompt can be given in time to avoid using an inaccurate densitometer for subsequent measurement, thereby improving the accuracy and reliability of the overall detection.

[0035] (2) The present invention obtains the data affecting density measurement based on the process of density measurement operation, analyzes and obtains the density measurement influence index, can identify and quantify various factors affecting density measurement, ensure that the measurement result is not affected by external interference, and compares it with the density measurement influence index threshold preset in the content detection database. When the density measurement influence index exceeds the threshold, it can prompt to measure again to reduce measurement errors and improve the accuracy of density measurement data.

A person skilled in the art can obtain other drawings based on the following drawings without creative work.

[0039] Figure 1 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] Reference Figure 1 As shown, the present invention provides a method for detecting the solid content of an emulsion, comprising: S1. Densitometer inspection: obtaining environmental data of the area to which the densitometer belongs and the test status data of the densitometer, comprehensively analyzing to obtain a densitometer test precision index, and comparing it with a densitometer test precision index boundary value preset in a content detection database to obtain a densitometer test precision comparison result, and determining whether an early warning prompt is required for the densitometer based on the densitometer test precision comparison result.

[0042] S2. Emulsion density measurement: The weighing device and the density meter respectively weigh and measure the density of each emulsion sample to be tested to obtain the weight of each emulsion sample to be tested and the density value of each emulsion sample to be tested. Based on the density measurement operation process, the data affecting the density measurement are obtained, and the measurement density influence index is analyzed and obtained. The index is compared with the measurement density influence index threshold preset in the content detection database to obtain the measurement density influence comparison result. According to the measurement density influence comparison result, it is determined whether the density value of each emulsion sample to be tested needs to be measured again.

[0043] In this embodiment, the above-mentioned emulsion samples to be tested are automatically extracted according to the set time, quantity and process by using an automated sampling system during the emulsion production process, and the extracted emulsion samples are recorded as the emulsion samples to be tested; before weighing the emulsion samples to be tested by a weighing device, the weighing device is first zeroed and calibrated to ensure its accuracy, the emulsion samples are poured into a container, placed on an electronic balance for weighing, and the weight of the emulsion samples is recorded; before measuring the density of the emulsion samples to be tested by a densitometer, the emulsion samples to be tested need to be gently mixed, and the emulsion samples are placed in the sample chamber of the densitometer to ensure that the samples will not overflow or be affected by the outside world, and the densitometer is started to perform the measurement operation.

[0044] S3. Emulsion solid content analysis: The density value of each emulsion sample to be tested is input into the corresponding function between the preset density value and the detected solid content, and the detected solid content of each emulsion sample to be tested is output.

[0045] S4. Emulsion drying: The heating device performs drying treatment on a certain emulsion sample to be tested, thereby obtaining and acquiring the weight of the solid sample, collecting the drying treatment operation data during the drying treatment of the certain emulsion sample to be tested by the heating device, analyzing and obtaining the emulsion evaporation index, and comparing it with the emulsion evaporation index limit value preset in the content detection database to obtain the emulsion evaporation comparison result, and judging whether to continue to perform the same drying treatment process on the remaining emulsion samples to be tested according to the emulsion evaporation comparison result to obtain the weight of each solid sample.

[0046] In this embodiment, the heating device performs drying treatment on the emulsion sample to be tested. The specific drying treatment process is: first, the emulsion sample to be tested is accurately weighed and its initial mass is recorded to ensure that the emulsion sample is evenly distributed in the heating container, and the heating device is started and set to specific temperature and humidity conditions (for example, the temperature can be set to 70-100°C, and the humidity is controlled within a certain range, and the specific value is determined according to the characteristics of the emulsion sample). This heating temperature setting should be able to effectively evaporate the water in the emulsion without causing thermal degradation or volatilization of other components in the emulsion. Inside the heating device, the emulsion sample will gradually heat and evaporate the water therein. Through heating, the water in the emulsion will be gradually evaporated and converted into gas. The drying process usually takes a certain time, and the specific time depends on the initial water content of the emulsion, the heating temperature, the heating method (such as hot air, infrared heating, microwave heating, etc.) and the amount and nature of the sample.

[0047] S5. Emulsion solid content verification: Analyze the weight of each solid sample and the weight of each emulsion sample to be tested to obtain the solid content of each emulsion sample to be tested, and perform difference processing with the detected solid content of each emulsion sample to be tested in turn to obtain the solid content deviation value of each emulsion sample to be tested, sum and mean analyze the solid content deviation values ​​of each emulsion sample to be tested to obtain the average deviation value of the solid content of the emulsion sample to be tested, and compare it with the solid content deviation threshold value of the emulsion sample to be tested preset in the content detection database to obtain the solid content deviation comparison result, and finally determine whether it is necessary to issue an early warning prompt for the corresponding function between the preset density value and the detected solid content according to the solid content deviation comparison result.

[0048] Specifically, the environmental data of the area to which the densitometer belongs includes the real-time environmental temperature and the real-time electromagnetic interference intensity of the densitometer during the test period.

[0049] It should be explained that the above-mentioned real-time ambient temperature can be measured by a semiconductor temperature sensor, and the real-time electromagnetic interference strength is obtained by using a portable radio receiver to detect the source of electromagnetic interference, while being able to capture interference signals on the radio frequency and help determine the source and strength of the interference signal, thereby obtaining the real-time electromagnetic interference strength; in this embodiment, the above-mentioned test cycle refers to the time period for performing the density meter test, and the test cycle can be determined based on the frequency of use and the use environment of the density meter. If the equipment is used very frequently or in a harsh environment, the test cycle may need to be shortened to ensure the performance and accuracy of the equipment.

[0050] The density meter test status data specifically includes the average response time, average vibration speed and average density resolution of the density meter during the test cycle.

[0051] It should be explained that the above average response time is within the test cycle of the density meter. A high-precision timer is used to record the response time of each measurement. The response time refers to the time interval from the issuance of the measurement command to the density meter giving the measurement result. The sum of all response times and the number of measurement requests are counted through the command collector, and the average response time is calculated using the formula "Average response time = total response time / number of requests". A vibration measuring instrument is used to measure the vibration frequency of the density meter during the test cycle, and the vibration speed is measured multiple times during the test cycle, and the average value is calculated to obtain the average vibration speed. During the test cycle, multiple measurements are performed using standard samples with known density values, and the results of each measurement are compared with the known density value of the standard sample. The measurement error is calculated, and the distribution of the measurement error is analyzed by the minimum detectable change method to determine the average density resolution of the density meter.

[0052] Specifically, the density meter tests the precision index, and the specific analysis process is as follows: The real-time ambient temperature of the density meter during the test cycle is processed with the ambient reference temperature preset in the content detection database to obtain the real-time temperature difference of the density meter during the test cycle.

[0053] The preset allowable temperature difference, the precise impact index corresponding to the preset real-time electromagnetic interference intensity unit value, the preset response allowable time, the precise impact index corresponding to the preset vibration speed unit value and the preset density reference resolution are extracted from the content detection database.

[0054] The preset allowable temperature difference, the precise impact index corresponding to the preset real-time electromagnetic interference intensity unit value, the preset allowable response time, the precise impact index corresponding to the preset vibration speed unit value, the preset density reference resolution, the real-time temperature difference of the density meter during the test cycle, the real-time electromagnetic interference intensity, the average response time, the average vibration speed and the average density resolution are comprehensively analyzed to obtain the density meter test precision index.

[0055] In this embodiment, during the test cycle of the density meter, there is a direct relationship of mutual influence between parameters such as real-time temperature difference, real-time electromagnetic interference intensity, average response time, average vibration speed and average density resolution. The real-time temperature difference is an important factor affecting the accuracy of density measurement. Since the density of a substance usually changes with temperature, the real-time temperature difference will cause a deviation in the measurement result. A larger temperature difference may cause an increase in the measurement error of the density meter, thereby reducing the average density resolution. An increase in the electromagnetic interference intensity will affect the electronic components and signal transmission of the density meter, resulting in instability or distortion of the measurement signal, resulting in an increase in the response time of the density meter, that is, the average response time becomes longer. A longer response time will lead to error accumulation during the measurement process, especially in a rapidly changing measurement environment. A longer response time may reduce the sensitivity of the density meter to density changes, thereby affecting the average density resolution. A larger vibration speed will interfere with the stable transmission and processing of the measurement signal, thereby reducing the average density resolution. The vibration speed will also aggravate the impact of real-time temperature difference and electromagnetic interference on the density meter measurement. For example, vibration may cause an increase in the measurement error of the temperature sensor, or aggravate the interference degree of electromagnetic interference on the measurement signal.

[0056] The density meter tests the precision index, and the specific analysis method is as follows: ; In the formula, is the precise index of the density meter test, e is a natural constant, is the starting time point of the test cycle, is the end time of the test cycle, t is any time point within the test cycle, , is the real-time temperature difference of the density meter at time point t during the test cycle, The allowable temperature difference preset for the content detection database, is the real-time electromagnetic interference intensity of the density meter at time point t during the test cycle, The precise impact index corresponding to the real-time electromagnetic interference intensity unit value preset for the content detection database, is the average response time of the density meter during the test period, The response time allowed for the content detection database is preset. is the average vibration speed of the density meter during the test period, The precise impact index corresponding to the vibration speed unit value preset in the content detection database, is the average density resolution of the densitometer during the test cycle, Density reference resolution preset for the content detection database.

[0057] It should be explained that any time point within the above-mentioned test cycle refers to any time point between the start and end of the test cycle, the real-time temperature difference refers to the difference between the real-time ambient temperature of the density meter during the test cycle and the ambient reference temperature preset in the content detection database; the allowable temperature difference preset in the content detection database refers to the preset maximum temperature fluctuation value in the content detection database; the real-time electromagnetic interference intensity refers to the interference intensity of the electromagnetic field at the current moment; the average response time refers to the average response time of the density meter to the density measurement request; the allowable response time preset in the content detection database refers to the preset and acceptable maximum response time of the content detection database; the average vibration speed refers to the average vibration speed within the test cycle; the average density resolution refers to the minimum density that the density detection instrument can distinguish; the density reference resolution preset in the content detection database refers to a density resolution standard preset in the content detection database; the real-time electromagnetic interference intensity preset in the content detection database The precise impact index corresponding to the unit value of the degree indicates the degree of influence of the unit value of the real-time electromagnetic interference intensity on the precise index of the density meter test. The corresponding relationship between the unit value of the real-time electromagnetic interference intensity and its corresponding precise impact index is stored in the content detection database. For example, the real-time electromagnetic interference intensity unit value is input into the content detection database, and the content detection database can match the precise impact index corresponding to the real-time electromagnetic interference intensity unit value. The value range in this embodiment is (0, 1); the precise impact index corresponding to the unit value of the vibration speed preset in the content detection database indicates the degree of influence of the unit value of the vibration speed on the precise index of the density meter test. The corresponding relationship between the unit value of the vibration speed and its corresponding precise impact index is stored in the content detection database. For example, the unit value of the vibration speed is input into the content detection database, and the content detection database can match the precise impact index corresponding to the unit value of the vibration speed. The value range in this embodiment is (0, 1).

[0058] In this embodiment, the real-time temperature difference is large, even greater than the preset allowable temperature difference, which will cause thermal expansion or contraction of the internal components of the densitometer, thereby affecting its measurement accuracy; the large real-time electromagnetic interference intensity will interfere with the electronic signal transmission and processing inside the densitometer, resulting in inaccurate measurement data; the long average response time, even greater than the preset allowable response time, means that there is a large delay between the densitometer receiving the measurement instruction and giving the measurement result, which not only reduces the test efficiency, but also may cause changes in measurement conditions due to time delays, thereby affecting the accuracy of the measurement results; the large average vibration speed will cause relative displacement or loosening of the internal components of the densitometer, thereby affecting its measurement accuracy; the small average density resolution, even less than the preset density reference resolution, means that the minimum density difference that the densitometer can distinguish during measurement is large, which limits the densitometer's ability in precise measurement and leads to inaccurate measurement results; therefore, by conducting a detailed analysis of the various parameters of the density meter test accuracy index, the key factors affecting the measurement accuracy can be identified, and corresponding measures can be taken to adjust or improve them, thereby improving the measurement accuracy of the densitometer.

[0059] Furthermore, the specific determination process of determining whether an early warning prompt is required for the density meter is as follows: If the density meter test precision index is greater than or equal to the density meter test precision index limit value preset in the content detection database, the density meter test precision comparison result is recorded as the density meter test first precision comparison result.

[0060] If the density meter test precision index is less than the density meter test precision index limit value preset in the content detection database, the density meter test precision comparison result is recorded as the density meter test second precision comparison result.

[0061] If the accurate comparison result of the density meter test is the second accurate comparison result of the density meter test, an early warning prompt is required for the density meter.

[0062] In this embodiment, the density meter test precision index is compared with the density meter test precision index boundary value preset in the content detection database. When the density meter test precision index is greater than or equal to the density meter test precision index boundary value preset in the content detection database, this means that the test result of the density meter has a higher accuracy, and its test precision index reaches or exceeds the preset standard. Therefore, in this case, the density meter test precision comparison result is recorded as the "densitometer test first precision comparison result", indicating that the density meter can stably and accurately complete the measurement task under the current test conditions without additional adjustment or calibration; when the density meter test precision index is less than the density meter test precision index boundary value preset in the content detection database, this means that the test result of the density meter is not accurate enough, and its test precision index is lower than the preset standard. In this case, the precision comparison result of the density meter test is recorded as "the second precise comparison result of the density meter test", indicating that the density meter may have certain problems, such as aging of the measuring element, inaccurate calibration, interference from environmental factors, etc., which cause its test result to be unstable or inaccurate. If the precision comparison result of the density meter test is "the second precise comparison result of the density meter test", the density meter needs to be warned. The specific warning prompt is that when the precision index of the density meter test is lower than the preset limit value, an alarm sound is automatically triggered. This sound is designed to quickly attract the user's attention and prompt the user to take immediate action, such as recalibrating the density meter to ensure its measurement accuracy, checking the status of the measuring element, replacing aged elements if necessary, evaluating and optimizing the test environment, and reducing possible interference factors, such as vibration, temperature changes, electromagnetic interference, etc.

[0063] Specifically, the data affecting density measurement include the number of bubbles in each emulsion sample to be tested, the real-time current and voltage of the density meter during the density measurement period, the real-time ambient humidity of the area to which the density meter belongs during the density measurement period, and the real-time wind speed.

[0064] It needs to be explained that the number of bubbles in the above-mentioned emulsion samples to be tested can be measured using ultrasonic technology. Before measurement, the emulsion sample should be ensured to be in a static state to avoid additional bubbles generated by stirring or vibration interfering with the measurement results. The real-time current and real-time voltage of the density meter during the density measurement period are measured and output by sensors and circuits inside the density meter in real time. The measurement of ambient humidity can be achieved using a humidity sensor, and the measurement of wind speed can be achieved using a wind speed sensor. The density measurement period refers to the time interval when the density meter performs continuous or periodic measurements. This period is an important parameter to ensure that the density meter can accurately and stably measure the density of the material. The setting of this time interval depends on many factors, including the properties of the measured material, the measurement environment, the accuracy and stability of the density meter, etc. By setting a reasonable measurement period, it can be ensured that the density meter has enough time to stabilize the reading during the measurement process and reduce errors caused by insufficient measurement time.

[0065] The real-time power of the densitometer during the density measurement period is obtained by multiplying the real-time current of the densitometer during the density measurement period by the real-time voltage.

[0066] Specifically, the measurement density impact index is analyzed in the following steps: The environmental data of the area to which the densitometer belongs during the density measurement period and the test status data of the densitometer are obtained, and a comprehensive analysis is performed to obtain the density measurement accuracy index of the densitometer during the density measurement period.

[0067] It needs to be explained that the environmental data of the area to which the above-mentioned densitometer belongs during the density measurement cycle and the densitometer test status data are the same as the environmental data of the area to which the above-mentioned densitometer belongs and the densitometer test status data. Therefore, the densitometer measurement accuracy index of the densitometer during the density measurement cycle is obtained by analyzing the environmental data of the area to which the densitometer belongs and the densitometer test status data. The same analysis process and method can obtain the densitometer measurement accuracy index of the densitometer during the density measurement cycle.

[0068] The real-time environmental humidity of the area to which the densitometer belongs during the density measurement period is subjected to difference processing with the environmental reference humidity preset in the content detection database to obtain the real-time humidity deviation value of the area to which the densitometer belongs during the density measurement period.

[0069] The density influence factor corresponding to the preset unit value of the number of bubbles, the density influence factor corresponding to the preset unit value of the density meter measurement accuracy index, the preset reference power, the preset humidity allowable deviation value and the preset allowable wind speed are extracted from the content detection database.

[0070] A comprehensive analysis is performed on the density influence factor corresponding to the preset unit value of the number of bubbles, the density influence factor corresponding to the preset unit value of the density meter measurement accuracy index, the preset reference power, the preset allowable humidity deviation value, the preset allowable wind speed, the number of bubbles in each emulsion sample to be tested, the real-time power of the density meter during the density measurement period, the real-time humidity deviation value of the area to which the density meter belongs during the density measurement period, the real-time wind speed and the density meter measurement accuracy index to obtain the measured density influence index.

[0071] In the present embodiment, there is a correlation of mutual influence among the number of bubbles in the above-mentioned emulsion samples to be tested, the real-time power of the densitometer during the density measurement period, the real-time humidity deviation value of the area to which the densitometer belongs during the density measurement period, the real-time wind speed and the density meter measurement accuracy index. When the wind speed is high, the emulsion surface may be more likely to fluctuate, resulting in an increase in the number of bubbles. The fluctuation of the real-time power may affect the working state of the electronic components inside the densitometer, thereby affecting the measurement of the humidity deviation value. The density meter measurement accuracy index reflects the measurement accuracy of the densitometer. When analyzing the measurement density influence index, the density meter measurement accuracy index needs to be considered to ensure the accuracy of the analysis results. If the measurement accuracy index of the densitometer is low, the effects of other influencing factors will be amplified, thereby affecting the final analysis results.

[0072] The specific analysis method of the measurement density influence index is as follows: ; In the formula, is the density influence index, e is a natural constant, x is the number of each emulsion sample to be tested, x=1, 2, 3, ..., k, k is the total number of emulsion samples to be tested, is the number of bubbles in the xth emulsion sample to be tested, The density influence factor corresponding to the bubble quantity unit value preset in the content detection database, It is the density measurement accuracy index of the density meter during the density measurement cycle. The density influence factor corresponding to the unit value of the density meter measurement precision index preset in the content detection database, is the starting time point of the density measurement cycle, is the end time of the density measurement cycle, u is any time point in the density measurement cycle, , is the real-time power of the densitometer at time point u during the density measurement cycle, Reference power preset for content detection database, is the real-time humidity deviation value of the densitometer at time point u in the area within the density measurement cycle, The humidity tolerance value preset for the content detection database, ) is the real-time wind speed of the densitometer at time point u in the area within the density measurement period, Allowable wind speed preset for the content detection database.

[0073] It should be explained that any time point within the above-mentioned density measurement cycle refers to any time point that can be randomly selected or focused on during the entire density measurement process. This time point can be any moment between the start and end of the measurement; the number of bubbles refers to the number of bubbles observed in the emulsion sample to be tested; the density meter measurement accuracy index within the density measurement cycle refers to an indicator to measure the measurement accuracy of the density meter within the current measurement cycle; the real-time power refers to the power actually consumed by the density meter at the current moment; the reference power preset in the content detection database refers to a standard value preset in the content detection database for comparing or evaluating the real-time power of the density meter; the real-time humidity deviation value refers to the difference between the real-time ambient humidity of the area to which the density meter belongs during the density measurement cycle and the ambient reference humidity preset in the content detection database; the humidity allowable deviation value preset in the content detection database refers to the standard value preset in the content detection database for judging whether the real-time humidity deviation value is within an acceptable range; the real-time wind speed refers to the speed of air flow in the measurement area; the allowable wind speed preset in the content detection database refers to the pre-set value for judging whether the real-time wind speed is within an acceptable range. Standard value; the density influence factor corresponding to the unit value of the number of bubbles preset in the content detection database, which indicates the degree of influence of the unit value of the number of bubbles on the measured density influence index. The content detection database stores the corresponding relationship between the unit value of the number of bubbles and its corresponding density influence factor. For example, the unit value of the number of bubbles is input into the content detection database, and the content detection database can match the density influence factor corresponding to the unit value of the number of bubbles. In this embodiment, the value range is (0, 1); the density influence factor corresponding to the unit value of the density meter measurement precision index preset in the content detection database, which indicates the degree of influence of the unit value of the density meter measurement precision index on the measured density influence index. The content detection database stores the corresponding relationship between the unit value of the density meter measurement precision index and its corresponding density influence factor. For example, the unit value of the density meter measurement precision index is input into the content detection database, and the content detection database can match the density influence factor corresponding to the unit value of the density meter measurement precision index. In this embodiment, the value range is (0, 1).

[0074] In this embodiment, more bubbles will interfere with the measurement of the density meter, because the density of the bubbles is significantly different from the density of the emulsion itself, and a large number of bubbles will increase the uncertainty of the measurement, directly leading to an increase in the measured density influence index; a low precision index means that the measurement result of the density meter is inaccurate, which will directly affect the reliability of the measured density influence index. A lower measurement precision index may lead to an increase in the misjudgment of the emulsion density, resulting in an increase in the measured density influence index; when the real-time power is large or small, that is, when the degree of deviation from the preset reference power is large, excessive power may cause the internal electronic components of the density meter to overheat, affecting its stability and accuracy, thereby increasing the measurement error, and too small power may not be able to meet the working requirements of the density meter, resulting in a weak measurement signal and inaccurate measurement results; a larger real-time wet When the humidity deviation value is even greater than the preset humidity allowable deviation value, the electronic components inside the density meter will be damp or corroded, thus affecting its measurement accuracy. At the same time, humidity changes may also affect the physical properties of the emulsion sample, such as density and volume, thereby introducing measurement errors; a larger real-time wind speed, even greater than the preset allowable wind speed, causes fluctuations on the emulsion surface, increases the number of bubbles, and interferes with the measurement of the density meter, resulting in an increase in the measured density influence index; therefore, through a detailed analysis of each parameter in the measured density influence index, the negative impact of each parameter on the measured density influence index can be identified and reduced, the measurement accuracy of the density meter can be improved, and the measurement environment (such as humidity, wind speed, etc.) and the working state of the density meter (such as power, etc.) can be adjusted to optimize the measurement conditions and improve the reliability of the measurement results.

[0075] Furthermore, the determination of whether it is necessary to measure the density value of each emulsion sample to be tested again is performed according to the comparison result of the measured density influence. The specific determination process is as follows: If the measurement density influence index is less than or equal to the measurement density influence index threshold preset in the content detection database, the measurement density influence comparison result is recorded as the measurement density first influence comparison result; If the measured density influence index is greater than the measured density influence index threshold preset in the content detection database, the measured density influence comparison result is recorded as the measured density second influence comparison result; If the measured density influence comparison result is the measured density second influence comparison result, it is necessary to measure the density value of each emulsion sample to be measured again.

[0076] In this embodiment, the measured density influence index is compared with the measured density influence index threshold preset in the content detection database. When the measured density influence index is less than or equal to the measured density influence index threshold preset in the content detection database, this means that the current measurement conditions, instrument performance, sample characteristics and other factors have little influence on the density measurement result, and the accuracy and reliability of the measurement result are high. Therefore, the measured density influence comparison result is recorded as the first measured density influence comparison result, indicating that the measurement result is credible and no further processing is required. When the measured density influence index is greater than the measured density influence index threshold preset in the content detection database, this means that the current measurement conditions, instrument performance or sample characteristics and other factors have a greater influence on the density measurement result, which may lead to the accuracy and reliability of the measurement result. Therefore, the measured density influence comparison result is recorded as the measured density second influence comparison result, indicating that the measurement result may have a large error, and the density value of each emulsion sample to be tested needs to be measured again. The specific measurement steps are: carefully check the measurement environment to ensure that the temperature, humidity, wind speed and other conditions meet the measurement requirements, check the calibration status of the density meter to ensure that the instrument performs well, if necessary, adjust the measurement parameters such as measurement time and measurement frequency to optimize the measurement conditions, ensure that the emulsion sample to be tested is uniform, free of bubbles, and meets the measurement requirements, if necessary, remix or process the sample to ensure its representativeness, use the optimized measurement conditions and the re-prepared sample to be tested for re-measurement, and operate in strict accordance with the measurement steps and operating procedures to ensure the accuracy and reliability of the measurement results.

[0077] In this embodiment, the density value of each emulsion sample to be tested is input into a preset corresponding function between the density value and the detected solid content, and the detected solid content of each emulsion sample to be tested is output, wherein the specific establishment process of the corresponding function between the density value and the detected solid content is: Prepare several polytetrafluoroethylene emulsion standard samples with known solid content, use a densitometer to measure the density value of each sample, and record the density value ρ and the corresponding solid content S of each sample.

[0078] Table 1 Density-solid content correspondence table of polytetrafluoroethylene emulsion standard samples

[0079] The density value and solid content in the density-solid content correspondence table of the polytetrafluoroethylene emulsion standard sample in Table 1 are input into the programming tool to fit the corresponding function between the density value and the detected solid content. The programming tool can automatically establish the corresponding function between the density value and the detected solid content according to the corresponding relationship between the input density value and the solid content. The specific corresponding function equation between the density value and the detected solid content is:

[0080] In the formula, S is the solid content, is the density value.

[0081] In this embodiment, the density value of each emulsion sample to be tested is recorded as , the measured density value Substitute into the function formula to calculate the solid content of each emulsion sample to be tested .

[0082] Specifically, the emulsion evaporation index has a specific analysis process as follows: The drying process operation data specifically includes the heating time of the heating device during the emulsion heating cycle, the real-time heating temperature, the average heating power, the average heating rate, the average ambient temperature, the average ambient humidity and the average electromagnetic interference intensity.

[0083] It should be explained that the above-mentioned heating time can be calculated by recording the start and stop time of the heating device, the real-time heating temperature can be measured by installing a temperature sensor in the heating device, the average heating power can be calculated by measuring the total energy consumption of the heating device during the heating cycle and dividing it by the heating time, the average heating rate can be calculated by measuring the temperature change of the emulsion during the heating cycle and dividing it by the heating time, the ambient average temperature can be measured by installing a temperature sensor in the drying treatment area, the ambient average humidity can be measured by installing a humidity sensor in the drying treatment area, and the electromagnetic average interference intensity can be measured by using an electromagnetic field probe in the drying treatment area. In this embodiment, the emulsion heating cycle refers to the time period from the start of heating of the emulsion to reaching the predetermined temperature and completing the heating process. The specific duration and conditions of this cycle will vary according to various factors such as the type of emulsion, the type of heating device, the purpose of heating and the process requirements.

[0084] In this embodiment, there is a certain mutual influence relationship between the heating time, real-time heating temperature, average heating power, average heating rate, ambient average temperature, ambient average humidity and average electromagnetic interference intensity of the heating device during the emulsion heating cycle. The longer the heating time, the higher the real-time heating temperature. When the emulsion quality, heating device efficiency and ambient temperature and other conditions remain unchanged, the greater the average heating power, the higher the average heating rate, and the shorter the time required for the emulsion to reach the target temperature. When the heating power is high, the equipment may generate more electromagnetic radiation, thereby increasing the electromagnetic interference intensity. The ambient average temperature and humidity jointly affect the heating efficiency. At higher ambient temperatures, the efficiency of the heating device may decrease because the temperature difference between the emulsion and the environment decreases, resulting in a lower heat exchange rate. At the same time, higher humidity may cause the evaporation of water in the emulsion to slow down, affecting the heating rate.

[0087] The average heating rate of the heating device in the emulsion heating cycle is ratio-processed with the heating reference rate preset in the content detection database to obtain the heating rate ratio of the heating device in the emulsion heating cycle.

[0088] The heating time, real-time heating temperature, heating power ratio, heating rate ratio, average ambient temperature, average ambient humidity and average electromagnetic interference intensity of the heating device during the emulsion heating cycle are comprehensively analyzed to obtain the emulsion evaporation index. The specific analysis method is as follows: Specifically, the emulsion evaporation index has a specific analysis process as follows: The drying process operation data specifically includes the heating time of the heating device during the emulsion heating cycle, the real-time heating temperature, the average heating power, the average heating rate, the average ambient temperature, the average ambient humidity and the average electromagnetic interference intensity.

In this embodiment, the emulsion heating cycle refers to the time period from the start of heating of the emulsion to reaching the predetermined temperature and completing the heating process. The specific duration and conditions of this cycle will vary according to various factors such as the type of emulsion, the type of heating device, the purpose of heating and the process requirements.

[0090] In this embodiment, there is a certain mutual influence relationship between the heating time, real-time heating temperature, average heating power, average heating rate, ambient average temperature, ambient average humidity and average electromagnetic interference intensity of the heating device during the emulsion heating cycle. The longer the heating time, the higher the real-time heating temperature. When the emulsion quality, heating device efficiency and ambient temperature and other conditions remain unchanged, the greater the average heating power, the higher the average heating rate, and the shorter the time required for the emulsion to reach the target temperature. When the heating power is high, the equipment may generate more electromagnetic radiation, thereby increasing the electromagnetic interference intensity. The ambient average temperature and humidity jointly affect the heating efficiency. At higher ambient temperatures, the efficiency of the heating device may decrease because the temperature difference between the emulsion and the environment decreases, resulting in a lower heat exchange rate. At the same time, higher humidity may cause the evaporation of water in the emulsion to slow down, affecting the heating rate.

[0093] The average heating rate of the heating device in the emulsion heating cycle is ratio-processed with the heating reference rate preset in the content detection database to obtain the heating rate ratio of the heating device in the emulsion heating cycle.

[0094] The heating time, real-time heating temperature, heating power ratio, heating rate ratio, average ambient temperature, average ambient humidity and average electromagnetic interference intensity of the heating device during the emulsion heating cycle are comprehensively analyzed to obtain the emulsion evaporation index. The specific analysis method is as follows: ; In the formula, is the emulsion evaporation index, e is a natural constant, is the heating time of the heating device during the emulsion heating cycle, The evaporation impact index corresponding to the heating time unit value preset in the content detection database, is the starting time point of the density measurement cycle, is the end time of the density measurement cycle, v is any time point in the density measurement cycle, , is the real-time heating temperature of the heating device at time point v during the emulsion heating cycle, Reference heating temperature preset for content detection database, is the heating power ratio of the heating device during the emulsion heating cycle, The evaporation influence index corresponding to the unit value of the heating power ratio preset in the content detection database, is the heating rate ratio of the heating device during the emulsion heating cycle, The evaporation influence index corresponding to the unit value of the heating rate ratio preset in the content detection database, is the average ambient temperature of the heating device during the emulsion heating cycle, Ambient reference temperature preset for content detection database, is the average humidity of the environment of the heating device during the emulsion heating cycle, Ambient reference humidity preset for content detection database, The average electromagnetic interference intensity of the heating device during the emulsion heating cycle, The evaporation impact index corresponding to the unit value of the average electromagnetic interference intensity preset in the content detection database.

[0095] It should be explained that any time point in the above-mentioned density measurement cycle refers to any specific moment randomly selected during the entire time period of density measurement; heating time refers to the length of time from the start of heating to the end of heating; real-time heating temperature refers to the current temperature value measured and recorded in real time by the temperature sensor during the heating process; the reference heating temperature preset in the content detection database refers to a target heating temperature preset before the content detection; the heating power ratio refers to the ratio between the average heating power of the heating device during the emulsion heating cycle and the heating reference power preset in the content detection database; the heating rate ratio refers to the ratio between the average heating rate of the heating device during the emulsion heating cycle and the heating reference rate preset in the content detection database; the ambient average temperature refers to the average temperature value of the surrounding environment during the heating process; the ambient reference temperature preset in the content detection database refers to an ambient temperature reference value preset based on historical experience before the content detection; the ambient average humidity refers to the average humidity value of the surrounding environment during the heating process; the ambient reference humidity preset in the content detection database refers to an ambient humidity reference value preset based on historical experience before the content detection; the electromagnetic average interference intensity refers to the average intensity of the electromagnetic interference signal in the surrounding environment during the heating process; the heating rate preset in the content detection database The evaporation influence index corresponding to the heating time unit value indicates the influence degree of the heating time unit value on the emulsion evaporation index. The content detection database stores the corresponding relationship between the heating time unit value and the corresponding evaporation influence index. For example, the heating time unit value is input into the content detection database, and the content detection database can match the evaporation influence index corresponding to the heating time unit value. In this embodiment, the value range is (0, 1); the evaporation influence index corresponding to the heating power ratio unit value preset in the content detection database indicates the influence degree of the heating power ratio unit value on the emulsion evaporation index. The content detection database stores the corresponding relationship between the heating power ratio unit value and the corresponding evaporation influence index. For example, the heating power ratio unit value is input into the content detection database, and the content detection database can match the evaporation influence index corresponding to the heating power ratio unit value, and the value range in this embodiment is (0, 1); the evaporation influence index corresponding to the heating rate ratio unit value preset in the content detection database indicates the degree of influence of the heating rate ratio unit value on the emulsion evaporation index, and the content detection database stores the corresponding relationship between the heating rate ratio unit value and its corresponding evaporation influence index, for example, the heating rate ratio unit value is input into the content detection database, and the content detection database can match the evaporation influence index corresponding to the heating rate ratio unit value, and the value range in this embodiment is (0, 1);The evaporation influence index corresponding to the electromagnetic average interference intensity unit value preset in the content detection database indicates the influence degree of the electromagnetic average interference intensity unit value on the emulsion evaporation index.

For example, the electromagnetic average interference intensity unit value is input into the content detection database, and the content detection database can match the evaporation influence index corresponding to the electromagnetic average interference intensity unit value. In this embodiment, the value range is (0, 1). ;

[0096] In this embodiment, a shorter heating time may not be enough to allow the emulsion to reach a state of full evaporation, resulting in failure to completely remove the water in the emulsion, thereby reducing the emulsion evaporation index; when the real-time heating temperature is lower, or even lower than the preset reference heating temperature, the evaporation rate of the emulsion will slow down, resulting in a lower evaporation index. The low temperature may also cause certain components in the emulsion to solidify or crystallize, affecting the evaporation effect and the quality of the emulsion; a smaller heating power ratio means that the energy provided by the heating device is insufficient, making it difficult for the emulsion to heat up quickly and reach the evaporation conditions, thereby reducing the evaporation index; a smaller heating rate ratio means that the emulsion heats up slowly, which will prolong the evaporation time, reduce the evaporation efficiency, and further affect the evaporation index; a higher or lower average ambient temperature, that is, when the degree of deviation from the preset ambient reference temperature is large, affects the heat transfer efficiency of the heating device and the evaporation rate of the emulsion. A high temperature environment may cause the emulsion to The water evaporates too quickly, resulting in unstable emulsion quality; a low temperature environment may slow down the evaporation rate and prolong the evaporation time; a larger or smaller average environmental humidity, that is, when the degree of deviation from the preset environmental reference humidity is large, when the environmental humidity is high, the water vapor content in the air is high, which will inhibit the evaporation process of the emulsion and reduce the evaporation index; too low humidity may cause the emulsion surface to dry too quickly and form a hard shell, hindering the continued evaporation of internal moisture; strong electromagnetic interference may affect the temperature control function of the heating device, making the temperature control unstable. For example, interference may cause inaccurate readings of the temperature control sensor, which in turn causes the heating temperature to fluctuate, thereby affecting the evaporation rate of the emulsion and causing a decrease in the emulsion evaporation index; therefore, through a detailed analysis of each parameter in the emulsion evaporation index, the heating time, real-time heating temperature, heating power ratio and heating rate ratio can be adjusted to optimize the heating conditions and improve the emulsion evaporation index.

[0097] In this embodiment, a certain emulsion sample to be tested is first dried by a heating device to obtain the weight of the solid sample, and the drying processing operation data of the emulsion sample to be tested by the heating device during the drying processing is collected, and the emulsion evaporation index is analyzed and obtained. The index is compared with the emulsion evaporation index boundary value preset in the content detection database to obtain the emulsion evaporation comparison result, and it is determined whether to continue to perform the same drying processing process on the remaining emulsion samples to be tested according to the emulsion evaporation comparison result to obtain the weight of each solid sample.

[0098] Specifically, the determination of whether to continue to perform the same drying process on the remaining emulsion samples to be tested according to the emulsion evaporation comparison result to obtain the weight of each solid sample is as follows: If the emulsion evaporation index is greater than or equal to the emulsion evaporation index limit value preset in the content detection database, the emulsion evaporation comparison result is recorded as the first evaporation comparison result.

[0099] If the emulsion evaporation index is less than the emulsion evaporation index limit value preset in the content detection database, the emulsion evaporation comparison result is recorded as the second evaporation comparison result.

[0100] If the emulsion evaporation comparison result is the first evaporation comparison result, the same drying process is continued for the remaining emulsion samples to be tested to obtain the weight of each solid sample.

[0101] If the emulsion evaporation comparison result is the second evaporation comparison result, it is necessary to give an early warning prompt to the heating device.

[0102] In this embodiment, the emulsion evaporation index is compared with the emulsion evaporation index limit value preset in the content detection database. When the emulsion evaporation index is greater than or equal to the emulsion evaporation index limit value preset in the content detection database, it means that the efficiency or performance of the heating device when drying the emulsion sample meets or exceeds the expected standard, that is, the evaporation of the emulsion is within the normal or expected range. In this case, the emulsion evaporation comparison result is recorded as the first evaporation comparison result, indicating that the evaporation of the emulsion is normal. Therefore, the same drying process can be continued for the remaining emulsion samples to be tested, thereby obtaining the weight of each solid sample, and the weight of each solid sample is summed and averaged in turn, and the obtained value is recorded as the average weight of the solid sample; when the emulsion evaporation index is less than the emulsion evaporation index limit value preset in the content detection database, it means that the efficiency or performance of the heating device when drying the emulsion sample is Lower than the expected standard, that is, the evaporation of the emulsion may not be sufficient. In this case, the emulsion evaporation comparison result is recorded as the second evaporation comparison result, and the heating device needs to be warned. The specific warning prompt can be a prompt message displayed on the display screen, such as "Please note that the emulsion is not fully evaporated". After receiving the warning prompt, the operator should immediately check the operating status of the heating device, including whether the power supply, temperature sensor, heating element, etc. are working properly. If any abnormality or fault is found, it should be repaired or replaced immediately. In addition, in order to ensure the accuracy of the solid content of the remaining samples, the heating device needs to be calibrated to ensure that it can accurately control the temperature and time; the remaining samples are more strictly monitored and tested to ensure that the parameters in the drying process meet the requirements; if possible, the heating device is upgraded or replaced to improve its performance and stability.

[0103] In this embodiment, the weight of each solid sample is processed with the weight of each emulsion sample to be tested to obtain the weight ratio of the solid content of each emulsion sample to be tested, and the ratio is multiplied by 100 to obtain the solid content of each emulsion sample to be tested, and the difference is processed with the average solid content of each emulsion sample to be tested to finally obtain the solid content deviation value of each emulsion sample to be tested, and the solid content deviation values ​​of each emulsion sample to be tested are summed and mean analyzed to finally obtain the average deviation value of the solid content of the emulsion samples to be tested.

[0104] Furthermore, the final determination of whether it is necessary to issue an early warning prompt for the corresponding function between the preset density value and the detected solid content is based on the solid content deviation comparison result. The specific determination process is: If the average solid content deviation value of the emulsion sample to be tested is less than or equal to the solid content deviation threshold of the emulsion sample to be tested preset in the content detection database, the solid content deviation comparison result is recorded as the solid content first deviation comparison result.

[0105] If the average deviation value of the solid content of the emulsion sample to be tested is greater than the solid content deviation threshold of the emulsion sample to be tested preset in the content detection database, the solid content deviation comparison result is recorded as the second solid content deviation comparison result.

[0106] If the solid content deviation comparison result is the solid content second deviation comparison result, it is necessary to give an early warning prompt for the corresponding function between the preset density value and the detected solid content.

[0107] In this embodiment, the average deviation value of the solid content of the emulsion sample to be tested is compared with the solid content deviation threshold value of the emulsion sample to be tested preset in the content detection database. When the average deviation value of the solid content of the emulsion sample to be tested is less than or equal to the solid content deviation threshold value of the emulsion sample to be tested preset in the content detection database, this means that the difference between the solid content of the emulsion sample to be tested and the average solid content is within an acceptable range, that is, the solid content detection result is relatively stable and consistent, which usually indicates that the detection process is more accurate, and the corresponding function between the preset density value and the detected solid content is in a normal state. In this case, the solid content deviation comparison result is recorded as the first solid content deviation comparison result, indicating that the current detection process and the preset function are reliable, and the current detection method and the corresponding function can continue to be used for subsequent emulsion sample detection; when the average deviation value of the solid content of the emulsion sample to be tested is greater than the content detection value, the solid content of the emulsion sample to be tested is less than or equal to the solid content deviation threshold value of the emulsion sample to be tested preset in the content detection database, this means that the difference between the solid content of the emulsion sample to be tested and the average solid content is within an acceptable range, that is, the solid content detection result is relatively stable and consistent, which usually indicates that the detection process is more accurate, and the corresponding function between the preset density value and the detected solid content is in a normal state. In this case, the solid content deviation comparison result is recorded as the first solid content deviation comparison result, indicating that the current detection process and the preset function are reliable, and the current detection method and the corresponding function can continue to be used for subsequent emulsion sample detection. When the solid content deviation threshold of the emulsion sample to be tested is exceeded by the preset database, this means that the difference between the solid content of the emulsion sample to be tested and the average solid content exceeds the acceptable range, that is, the solid content test result may have large fluctuations or errors. This may be because the corresponding function between the preset density value and the detected solid content is no longer accurate. In this case, the solid content deviation comparison result is recorded as the second solid content deviation comparison result. At the same time, an early warning prompt is required for the corresponding function between the preset density value and the detected solid content. The specific early warning prompt can be given by voice broadcast, for example, "Warning! The average deviation value of the solid content of the emulsion sample to be tested has exceeded the preset threshold range, please check." After receiving the early warning prompt, the staff needs to re-evaluate and verify the corresponding function between the preset density value and the detected solid content, and make corrections or updates when necessary to ensure the accuracy and applicability of the function.
