In addition, the existing detection and evaluation methods lack dynamic adaptability and cannot flexibly adjust the evaluation indicators and weights according to the specific use conditions and performance requirements of the resin, resulting in inaccurate evaluation results and difficulty in effectively guiding quality control and process optimization during the production, processing and application of the resin.

BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 It is a structural block diagram provided by an embodiment of the present invention; DETAILED DESCRIPTION

[0041] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0042] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0043] like Figure 1 As shown, a resin material viscosity detection and evaluation system provided by an embodiment of the present invention includes a data acquisition module, a data calculation module, a qualified judgment module and a report generation module;

[0044] The data acquisition module is used to collect the original measurement data of the resin material and transmit it to the data calculation module;

[0045] The data calculation module is used to calculate the viscosity-related parameters of the resin material according to the original measurement data, and transmit the calculation results to the qualification judgment module;

[0046] The qualified judgment module is used to judge the viscosity-related parameters according to the preset qualified standards, and transmit the judgment results to the report generation module;

[0047] The report generation module is used to generate a test report including the original measurement data, calculation results and determination results.

[0048] As the data source of the entire system, the data acquisition module is responsible for comprehensive data collection of resin materials using a variety of professional measuring instruments. These instruments include capillary viscometers, rotational viscometers and rheometers, etc., which are used to obtain original measurement data in different aspects. For example, the capillary viscometer measures the precise time (t) required for the sample to flow through a certain volume in the capillary. This time data will serve as the key basis for the subsequent calculation of kinematic viscosity; the torque (M) measured by the rotational viscometer is used to calculate the dynamic viscosity; the rheometer is used to obtain the viscosity (η) at different shear rates 1, η 2 ) and the viscosity at different temperatures (η 1 '、η 2 ') and the corresponding temperature value (T 1 、T 2 ), these data provide the basis for in-depth analysis of the thixotropy and viscosity-temperature characteristics of the resin. The collected data will be accurately and timely transmitted to the data calculation module to ensure the continuity and integrity of the data, laying a solid foundation for subsequent accurate calculation and analysis.

[0049] After receiving the raw data from the data acquisition module, the data calculation module processes and calculates it using specific mathematical formulas and algorithms, thereby obtaining a series of parameters closely related to the viscosity of the resin. These parameters will fully reflect the viscosity characteristics of the resin, provide a key basis for subsequent qualified judgment, and ensure that each parameter can accurately quantify the specific viscosity behavior of the resin through precise calculation.

[0050] The qualified judgment module makes a detailed comparison and judgment on the viscosity-related parameters output by the data calculation module according to the preset strict qualified standards. This module adopts scientific and reasonable judgment logic to ensure that it can accurately identify whether the resin material meets the specific quality requirements. Its judgment result will directly determine whether the resin material is qualified under the current evaluation system, providing clear quality guidance for production and application.

[0051] The report generation module systematically organizes and standardizes the original measurement data, detailed calculation results and final judgment results in the entire test and evaluation process to generate a complete, detailed and easy-to-understand test report. This report is not only a comprehensive record of the test process, but also provides intuitive and accurate quality information for users, producers and researchers of resin materials, which is convenient for them to refer to in subsequent decision-making, such as whether to continue to use the batch of resin, whether the production process needs to be adjusted, etc.

[0052] Furthermore, the raw measurement data collected by the data acquisition module include the time (t) required for the sample to flow through a certain volume in the capillary measured by a capillary viscometer, the torque (M) measured by a rotational viscometer, and the viscosity at different shear rates (η 1 , η 2 ) and the viscosity at different temperatures (η 1 '、η 2 ') and the corresponding temperature value (T 1 、T 2 );

[0053] The data calculation module calculates the kinematic viscosity (ν), dynamic viscosity (η), thixotropy index (TI) and viscosity-temperature coefficient (VTC) of the resin material according to the original measurement data, wherein:

[0054] The calculation formula of the kinematic viscosity (ν) is: ν = K × t, where K is the capillary viscometer constant;

[0055] The calculation formula of the dynamic viscosity (η) is: η=M×C, where C is the calibration coefficient of the rotational viscometer;

[0056] The calculation formula of the thixotropy index (TI) is: TI = η 1 / η 2 , where η 1 For low shear rate (γ 1 ) under viscosity, η 2 For high shear rate (γ 2 ) and γ 1 <γ 2 ;

[0057] The viscosity-temperature coefficient (VTC) is calculated as follows: VTC = |(η 2 '-η 1 ') / (T 2 -T 1 )|, where η 1 '、η 2 ' are respectively the temperature T 1 , T 2 The viscosity under the condition of , and the absolute value is used to ensure the non-negativity of the viscosity-temperature coefficient, so as to ensure the rationality and physical significance of the subsequent calculation of related parameters.

[0058] For example, the above calculation example is as follows:

[0059] Capillary viscometer measurement: The data acquisition module uses a capillary viscometer to measure the time (t) required for a resin sample to flow through a certain volume in a capillary. For example, when testing a specific resin, the measured time t = 120s (this data is only an example, the actual measurement value will vary depending on the type of resin and measurement conditions), and the capillary viscometer constant K = 0.4mm is known. 2 / s 2 The precise measurement of this time data is crucial for the accurate calculation of the subsequent kinematic viscosity, because the calculation formula of kinematic viscosity (ν) is ν = K × t. In this example, the kinematic viscosity can be calculated according to the formula ν = 0.4 × 120 = 48 mm 2 / s, this parameter reflects the flow properties of the resin under gravity and is closely related to factors such as the molecular size, structure and solvent content of the resin. It is one of the basic indicators for evaluating the viscosity characteristics of the resin.

[0060] Rotational viscometer measurement: Use a rotational viscometer to measure torque (M). Assuming that the torque M = 0.06 N·m is measured in one measurement, the calibration coefficient of the rotational viscometer is C = 8 Pa·s / (N·m). Through the calculation formula of dynamic viscosity (η) η = M×C, the dynamic viscosity η = 0.06×8 = 0.48 Pa·s can be calculated. Dynamic viscosity takes into account the internal friction of the resin. It is related to the concentration of the resin, the chain length of the polymer and the interaction, etc. It can more comprehensively describe the viscosity characteristics of the resin and is one of the important parameters for evaluating the quality and performance of the resin.

[0061] Rheometer measurement: Rheometer is used to measure the 1 = Viscosity η at 2s-1 1 =3Pa·s, at high shear rate γ 2 =80s -1 Viscosity η 2 =0.6Pa·s, through the calculation formula of thixotropy index (TI) TI = η 1 / η 2 , we can get TI = 3 / 0.6 = 5. The thixotropy index reflects the change in viscosity of the resin when it is subjected to force. For some resin applications that need to have good fluidity during construction but can maintain a certain shape in a static state (such as coatings, adhesives, etc.), thixotropy is a key performance indicator, which directly affects the operability and stability of the resin in actual use. At the same time, the rheometer also measures the viscosity of the resin at temperature T 1 =Viscosity η at 25°C 1 '=4Pa·s,at temperature T 2 = Viscosity η at 50°C 2 '=2Pa·s, according to the calculation formula of viscosity-temperature coefficient (VTC) VTC=|(η 2 '-η 1 ') / (T 2 -T 1 )|, we can get VTC = |(2-4) / (50-25)| = 0.08Pa·s / ℃. The viscosity-temperature coefficient reflects the sensitivity of the viscosity of the resin to temperature. For resin products used in different temperature environments, understanding their viscosity-temperature characteristics helps control the processing technology and product performance, ensuring that the resin can maintain appropriate viscosity under various temperature conditions, thereby ensuring its use effect and quality stability.

[0062] The data calculation module is also used to calculate the comprehensive evaluation factor (F), and the calculation formula of the comprehensive evaluation factor (F) is:

[0063]

[0064] In the above example, we know that η=0.48Pa·s, VTC=0.08Pa·s / ℃, and we can get The comprehensive evaluation factor (F) takes into account the two important parameters of dynamic viscosity and viscosity-temperature coefficient, and integrates them through a specific mathematical relationship, so that the factor can more comprehensively reflect the comprehensive performance of the resin in terms of viscosity and viscosity-temperature stability. It provides an intermediate variable for the subsequent calculation of the comprehensive evaluation index (E), further improves the quantitative evaluation system of the viscosity characteristics of the resin, and can more accurately measure the performance of the resin in complex practical application scenarios, providing stronger support for the quality control and performance optimization of resin materials.

[0065] The data calculation module is further used to calculate the comprehensive evaluation index (E), and the calculation formula of the comprehensive evaluation index (E) is:

[0066]

[0067] The data calculation module is based on the comprehensive evaluation factor (F) obtained in claim 3 and the kinematic viscosity (ν) and thixotropy index (TI) in claim 2. In the previous example, it is known that F≈1.697, ν=48mm 2 / s, TI=5, substituting into the formula we get The comprehensive evaluation index (E) organically combines the combined effects of kinematic viscosity, dynamic viscosity and viscosity-temperature coefficient and thixotropy index, and conducts a comprehensive and in-depth quantitative evaluation of the viscosity characteristics of the resin from multiple dimensions. It can more intuitively reflect the comprehensive performance of the resin in various practical application scenarios. By comparing with the preset qualified range, it can quickly and accurately determine whether the resin material meets specific quality requirements, providing a key decision-making basis for the production, processing and application of the resin, and improving the efficiency and accuracy of quality control.

[0068] Furthermore, the comprehensive evaluation index (E) described in the qualified judgment module is judged to be qualified, specifically: the comprehensive evaluation index (E) is compared with a preset qualified range, and when E falls within the qualified range, the resin material is judged to be qualified, otherwise it is judged to be unqualified; the test report generated by the report generation module also includes detailed information on the comprehensive evaluation index (E) and its qualified judgment result.

[0069] The qualified judgment module compares the comprehensive evaluation index (E) with the preset qualified range. For example, for a certain type of resin, the qualified range of E is [10,20]. In the above example, the calculated E≈16.29. Since 16.29 falls within the qualified range, the resin material is judged to be qualified in terms of the comprehensive evaluation index (E). If the E value is less than 10 or greater than 20, the resin material is judged to be unqualified. The report generation module will record the E value and its qualified judgment results in detail in the test report, including the specific value, the comparison with the qualified range, and the final judgment conclusion (qualified / unqualified). In this way, users can clearly understand the evaluation of the comprehensive performance of the resin material, so that they can take corresponding measures according to the judgment results, such as continuing to use the batch of resin, fine-tuning the production process, or re-screening the raw materials, etc., thereby effectively ensuring the quality stability and reliability of the resin material in practical applications, and improving production efficiency and product quality.

[0070] Furthermore, the qualification determination module is also used to calculate the dynamic weight coefficient (w 1 、w 2 ), and weighting the kinematic viscosity (ν) and the comprehensive evaluation factor (F) by a dynamic weight coefficient to obtain a comprehensive evaluation score (S) to further improve the accuracy of the evaluation;

[0071] The dynamic weight coefficient (w 1 、w 2 ) is calculated as:

[0072]

[0073] w 2 =1-w 1 ;

[0074] Where a, b, and c are empirical constants obtained by fitting and analyzing the test data of a large number of resin samples in different application scenarios;

[0075] The calculation formula of the comprehensive evaluation score (S) is:

[0076]

[0077] where ν ref is the reference standard value of kinematic viscosity, F ref is the reference standard value of the comprehensive evaluation factor;

[0078] The qualified judgment module compares the comprehensive evaluation score (S) with a preset qualified score range, and when S falls within the qualified score range, the resin material is judged to be qualified under the weighted evaluation, otherwise it is judged to be unqualified;

[0079] The test report generated by the report generation module also includes the dynamic weight coefficient (w 1 、w 2 ), comprehensive evaluation score (S) and detailed information on its qualified judgment results.

[0080] Assume that in a specific application scenario, through data analysis, we get a=0.4,b=0.6,c=-0.5. Knowing that TI=5,VTC=0.08Pa·s / ℃, we can calculate by substituting into the formula: Then 2 =1-w 1 =0.18. Dynamic weight coefficient (w 1 、w 2 ) can automatically adjust the weight of kinematic viscosity (ν) and comprehensive evaluation factor (F) in comprehensive evaluation according to the thixotropy index (TI) and viscosity-temperature coefficient (VTC) of the resin, so that the evaluation results are more in line with the performance requirements of the resin in actual applications. For example, in some applications that are more sensitive to temperature changes, the viscosity-temperature coefficient (VTC) is large, and w 2 The TI value will increase accordingly, which increases the weight of the comprehensive evaluation factor (F) in the comprehensive evaluation score (S), and highlights the influence of viscosity-temperature characteristics on resin performance. In some applications with high requirements for thixotropy, the TI value is larger, and w 1 The dynamic weighting mechanism can flexibly adjust the weight of the evaluation index according to the specific characteristics and application scenarios of the resin, realize the precision and personalization of the evaluation, and provide a more scientific and effective method for the quality control of resin materials.

[0081] After calculating the dynamic weight coefficient w 1 、w 2 After that, the qualified judgment module uses the formula Calculate the comprehensive evaluation score S. For example, in the above example, the reference standard value v of kinematic viscosity ref =45mm 2 / s, reference standard value of comprehensive evaluation factor F ref =1.5, and F≈1.697, ν=48mm 2 / s, substituting it into S≈0.96. The comprehensive evaluation score (S) comprehensively considers the contribution of kinematic viscosity and comprehensive evaluation factors under different weights. By comparing with the preset qualified score range, it can more comprehensively and accurately judge the qualification of the resin material under weighted evaluation. For example, assuming that after a large number of experiments, it is determined that the qualified score range for the weighted evaluation of the resin material is [0.8,1.2]. Since the calculated S≈0.96 falls within this range, the resin material is judged to be qualified under the weighted evaluation. The report generation module will record the dynamic weight coefficient (w 1 、w 2 ), comprehensive evaluation score (S) and its qualified judgment results, including the specific numerical calculation process, comparison with the qualified range and the final judgment conclusion (qualified / unqualified), provide users with detailed and accurate resin quality evaluation information, help users better understand the performance characteristics and quality status of resin materials, and make more reasonable decisions.

[0082] Furthermore, data is transmitted between the data acquisition module and the data calculation module, between the data calculation module and the qualification judgment module, and between the qualification judgment module and the report generation module through wired or wireless communication, and data encryption and verification technology is used to ensure the accuracy and security of data transmission and prevent data loss, tampering or error during transmission.

[0083] Furthermore, the resin material viscosity detection and evaluation system also includes a data storage module for storing the original measurement data, calculation results, determination results, test reports and other data during the operation of the system;

[0084] The data storage module is connected with the data acquisition module, the data calculation module, the qualified determination module and the report generation module via a high-speed data bus, and the high-speed data bus adopts parallel transmission technology and a cache mechanism to realize fast storage and reading of data and improve the overall operation efficiency of the system;

[0085] The data storage module has data backup and recovery functions, can regularly back up stored data, and perform recovery operations when data is lost or damaged, thereby ensuring the integrity and reliability of the data.

[0086] Further verification is done through the following examples:

[0087] 1. Data collection:

[0088] Capillary viscometer measurement data: time t = 150s, constant K = 0.35mm 2 / s 2 .

[0089] Rotational viscometer measurement data: Torque M = 0.04 N·m, calibration coefficient C = 9 Pa·s / (N·m)

[0090] Rheometer Measurement Data: Low Shear Rate γ 1 =1.5s -1 Lower viscosity η 1 =2.5Pa·s, high shear rate γ 2 =60s -1 Lower viscosity η 2 =0.5Pa·s, temperature T 1 =Viscosity η at 30°C 1 ′=3.5Pa·s,temperature T 2 =Viscosity η at 45°C 2 ′=1.5Pa·s.

[0091] 2. Data calculation:

[0092] Kinematic viscosity (ν): ν = 0.35 × 150 = 52.5 mm 2 / s.

[0093] Dynamic viscosity (η): η = 0.04 × 9 = 0.36 Pa·s.

[0094] Thixotropy index (TI): TI=2.5 / 0.5=5.

[0095] Viscosity Temperature Coefficient (VTC):

[0096] Comprehensive evaluation factor (F):

[0097] Comprehensive evaluation index (E):

[0098] 3. Qualification determination:

[0099] Since the qualified range of E is [10, 20] and 10.45 is within this range, the resin material is qualified in terms of the comprehensive evaluation index (E).

[0100] Calculate the dynamic weight coefficient:

[0101]

[0102] w 2 =0.19

[0103] Assuming the kinematic viscosity reference standard value ν ref =50mm 2 / s, comprehensive evaluation factor reference standard value F ref =1, then the comprehensive evaluation score (S) is:

[0104] Since the qualified score range is [0.8, 1.2], and 0.95 falls within this range, the resin material is judged to be qualified under the weighted evaluation, and the resin material is comprehensively judged to be qualified.
