Description

Technical Field

[0001] This invention relates to the field of measurement, specifically to a method for detecting the concentration of rubber solution during rubber preparation. Background Technology

[0002] The production process of rubber products includes multiple steps such as plasticizing, mixing, and molding, culminating in molded rubber products like tires. As these rubber products undergo increasingly stringent performance requirements during use, the manufacturing process directly determines their quality. Rubber solutions are generally viscous liquids. Chemical rubber refining technology is an advanced technique that mixes synthetic rubber with fillers in a liquid state to produce new composite rubber materials. Materials prepared using this technology are hailed as "liquid gold" in the industry. Liquid-liquid mixing of raw rubber solutions, filler slurries, and additives eliminates the energy-intensive multi-stage mixing steps. Simultaneously, liquid-liquid mixing improves the dispersion of fillers and additives in the rubber, thereby significantly enhancing product performance. Furthermore, the parameter selection and process level in a company's rubber manufacturing process directly affect the quality of its products, thus directly impacting social acceptance. However, companies often lack sufficient protection for their core technologies, such as parameter selection and process flow.

[0003] Existing technologies describe methods for sampling and testing rubber compounds during the rubber-making process, and also provide methods for monitoring rubber compound concentration, such as physical and optical measurement methods (spectral analysis, scattering, etc.). For example, invention patent CN 111238858 A discloses an online rubber compound sampling device, which includes a conveying component, a cutting component, a receiving component, a heating component, and a coding component. This device can automatically realize the online cutting, sampling, and testing process of rubber compounds, thereby improving the efficiency of rubber compound testing while ensuring time and labor savings. This allows manufacturers to adjust process parameters in a timely manner to achieve quality control. However, although this method achieves automated sampling and testing, it still requires additional acquisition of cut material for testing, resulting in low real-time detection capability, and the data is not protected at the testing end. Chinese patent application CN115112574A discloses a method, system, computing device, and medium for detecting the trace moisture content of silicone rubber. The method includes scanning the silicone rubber with electromagnetic waves at a preset frequency (terahertz frequency); acquiring the scanning data of the electromagnetic waves, including a time-domain signal; converting the time-domain signal into a frequency-domain signal; and obtaining the moisture content information of the silicone rubber based on the frequency-domain signal and a reference spectrum, where the reference spectrum is the spectral information of the silicone rubber when it is dry. Using the detection method provided in this invention, scanning the silicone rubber with electromagnetic waves at a preset frequency can quickly and accurately obtain the moisture content information of the silicone rubber. Compared to traditional weighing methods, this detection method achieves rapid detection of water content in silicone rubber and has advantages such as high accuracy and ease of operation. It uses electromagnetic wave scanning combined with spectral reference comparison to measure the water concentration of rubber products; however, it is time-consuming, and the parameter data is not kept confidential at the detection end. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for detecting the concentration of adhesive solution. This method can detect the concentration in the adhesive manufacturing process, ensuring the dispersion of compounding agents and excipients in the adhesive solution during mixing, while also ensuring the confidentiality of data detection and collection. This allows for precise control of parameters during heating and stirring in the reaction vessel, thereby improving product quality.

[0005] This invention provides a method for detecting the concentration of an adhesive solution, which includes the following steps performed sequentially:

[0006] (1) Prepare the raw materials, which include raw rubber, compounding agents and excipients;

[0007] (2) Pre-treat the raw materials, heat-dry them during the raw rubber pre-treatment process to soften them appropriately, collect the temperature values ​​of multiple raw rubber pre-treatments at the first frequency, and detect the concentration values ​​of the corresponding components.

[0008] (3) The collected temperature values ​​form a pre-processing temperature set, the collected concentration values ​​form a pre-processing concentration set, the pre-processing concentration set is directly stored in the first memory, and the pre-processing temperature set is encrypted and then stored in the second memory.

[0009] (4) Perform plasticizing treatment. Collect temperature and concentration values ​​of multiple raw rubber plasticizing processes at the same collection frequency as in step (2). After mapping and matching according to the collection time points, a plasticizing concentration-temperature set is formed. The concentration-temperature set is encrypted and stored in the second memory.

[0010] (5) Control the temperature during the mixing process, and stir the plasticized raw rubber, compounding agents and auxiliary materials in the reactor under controlled temperature;

[0011] (6) Collect temperature and concentration values ​​during multiple mixing processes at the same collection frequency as in step (2), map and match the concentration and temperature values ​​according to the collection time points to form a mixing concentration-temperature set, encrypt the mixing concentration-temperature set and store it in the third memory.

[0012] (7) Set different levels of access permissions and different access restrictions for the first, second and third memory;

[0013] (8) When calling concentration and temperature data, verify the caller's permissions. If the permission requirements are met, the encrypted data stored in the first, second and / or third memory will be fed back according to the call requirements.

[0014] The concentration of components is detected using a spectroscopic method.

[0015] Specifically, the encryption of the preprocessing temperature set in step (3) includes:

[0016] (3.1) Randomly generate a set of random number combinations corresponding to the number of temperature values ​​in the pretreatment temperature set, and add the random numbers in the random number combination to the temperature values ​​in the pretreatment temperature set to construct a random pretreatment temperature set;

[0017] (3.2) The random number combination is packaged and encrypted and stored in the first memory, and the random preprocessed temperature set is stored in the second memory.

[0018] The encryption of the concentration-temperature set in step (4) specifically includes the following steps:

[0019] (4.1) Call the random number combination that has been packaged and encrypted and stored in the first memory, and decode it to obtain the random number combination data;

[0020] (4.2) After repeatedly arranging the random numbers in the random number combination, add the corresponding temperature values ​​of the plasticizing concentration-temperature set to construct a random plasticizing concentration-temperature set and store it in the second memory.

[0021] The densification of the mixing concentration-temperature set in step (6) specifically includes the following steps:

[0022] (6.1) Convert the number of temperature values ​​in the preprocessed temperature set into an even number of binary numbers, and divide the even number of binary numbers into two preset binary numbers with the same number of bits.

[0023] (6.2) Convert the concentration and temperature values ​​in the mixing concentration-temperature set into binary numbers of concentration and binary numbers of temperature, respectively;

[0024] (6.3) Insert two preset binary numbers into the middle of the concentration binary number and the temperature binary number respectively to form encrypted binary concentration value and binary temperature value;

[0025] (6.4) Convert the binary concentration value and binary temperature value into decimal respectively to form an encrypted mixing concentration-temperature set;

[0026] (6.3) Store the encrypted mixing concentration-temperature set in a third memory.

[0027] Step (8) further includes decrypting the encrypted data, completing the monitoring and analysis of concentration and temperature, and regulating the preparation process under the desired environment and parameters.

[0028] In step (6.1), if the converted binary number has an odd number of bits, then zeros are added to the front to form a binary number with an even number of bits.

[0029] The method for detecting the concentration of the adhesive solution of this invention can achieve the following: Utilizing a combination of random and binary methods with different storage paths, it simultaneously detects the concentration and maps and matches the concentration and temperature at the acquisition time points, effectively encrypting and protecting the acquired data to prevent leakage of core process parameters. Furthermore, the data acquisition standards before and after measurement are consistent and correlated, resulting in better accuracy. Simultaneously, it detects the concentration situation in the process flow and ensures the confidentiality of data detection and collection, thereby enabling precise control of parameters during heating and stirring in the reactor, improving product quality. The overall temperature data acquisition is controllable, facilitating comprehensive monitoring and analysis of the preparation process. Attached Figure Description

[0030] Figure 1 This is a schematic diagram of the method for detecting the concentration of adhesive solution. Detailed Implementation

[0031] The specific implementation of the present invention will be described in detail below. It should be noted that the following implementation is only for further illustration of the present invention and should not be construed as a limitation on the scope of protection of the present invention. Some non-essential improvements and adjustments made to the present invention by those skilled in the art based on the above description of the present invention still fall within the scope of protection of the present invention.

[0032] This invention provides an online temperature measurement method for rubber compound, as shown in the attached figure. Figure 1 As shown, this is a schematic diagram of the method for detecting the concentration of adhesive solution, which will be described in detail below.

[0033] This invention provides a method for detecting the concentration of an adhesive solution, the implementation process of which is shown in the attached figure. Figure 1 As shown, it also schematically illustrates an application scenario of the method for detecting the concentration of the adhesive solution according to the present invention. It should be noted that... Figure 1 The scenarios illustrated are merely examples of applications applicable to this invention, intended to help those skilled in the art understand the technical content of this invention, but do not imply that this invention cannot be used in other devices, systems, environments, or scenarios. It should be noted that the adhesive concentration detection method provided by this invention can be used in related aspects of the measurement and monitoring technology field, and can also be used in other adaptable fields; the application field of the adhesive concentration detection method provided by this invention is not limited.

[0034] like Figure 1 As shown, the method for detecting the concentration of the adhesive solution includes the following specific implementation steps performed in sequence.

[0035] First, the raw materials are prepared and pretreated. These raw materials include raw rubber, compounding agents, and auxiliaries. The pretreatment process mainly involves bringing the raw materials to suitable preparation conditions. For example, raw rubber is softened by heat drying, and compounding agents and auxiliaries are appropriately melted, dried, and filtered to meet the corresponding preparation requirements. Specifically, compounding agents are materials added to improve certain properties of rubber products, such as hard carbon black (abrasion resistance) and flame retardants (flame retardancy). Auxiliaries are auxiliary materials added to enhance mechanical strength and limit deformation, such as fiber materials and metal materials. It should be noted that compounding agents and auxiliaries can be selected appropriately based on actual conditions and in suitable proportions according to performance requirements.

[0036] The process of forming the adhesive solution involves converting raw rubber and its processing mixture into a liquid state. During this process, the adhesive solution is in a liquid state, and its overall concentration changes with the addition of compounding agents and excipients. The composition of its concentration components is influenced not only by selecting appropriate ratios according to performance requirements but also by the liquid conversion and raw rubber processing mixture processes, as well as moisture changes. It is particularly affected by multiple factors such as pressure, humidity, and temperature. Temperature directly impacts the concentration change and accuracy, having a direct influence on the conversion to liquid state during the mixing process and the mixing in a liquid state. This invention incorporates temperature factors into the concentration measurement process and combines it with the concentration measurement, enabling precise temperature control and controllable concentration adaptability in subsequent steps. This allows for optimal control of the overall preparation process, resulting in high-quality adhesive solution products. It should be noted that the concentration measurement method can be optical, using continuous wavelength light to scan the adhesive solution at multiple stages of the preparation process. The spectral information obtained through absorption peak expression is then analyzed to determine the component concentration.

[0037] The pretreatment of raw rubber includes heating it to soften it appropriately and detecting the concentration of components during the pretreatment process using spectroscopic methods. In this step, since the concentration of the main components of raw rubber is relatively well-defined and clearly stated in existing descriptions of its composition and properties, no special processing is required after the concentration measurement; the data is simply stored for later reference. To improve the accuracy and efficiency of temperature measurement while maintaining safety, this invention introduces specific temperature measurement and data processing / storage methods during raw material pretreatment. These methods are integrated with subsequent temperature measurement steps, ensuring overall accuracy, efficiency, and reliability.

[0038] Specifically, raw rubber is a major component of the raw materials, accounting for a relatively high proportion. Therefore, real-time temperature measurement is performed during raw rubber pretreatment, specifically during operations such as heat drying. This measurement is combined with safety considerations, allowing the temperature data to be integrated with subsequent temperature measurement steps, ensuring overall accuracy, efficiency, and safety. However, the composition and performance properties of raw rubber are relatively clearly defined in existing specifications. Concentration measurement is inherently difficult and costly; therefore, the concentration measured in this step is not specially processed but stored for future reference.

[0039] During measurement, multiple temperature values ​​from the raw rubber pretreatment process are collected at a first frequency, and the concentration values ​​of corresponding components during the pretreatment process are detected using spectroscopy. The collected temperature values ​​form a pretreatment temperature set, and the collected concentration values ​​form a pretreatment concentration set, which are directly stored in the first memory. Then, a random number combination corresponding to the number of temperature values ​​in the pretreatment temperature set is randomly generated. Each random number in the combination is added to a corresponding temperature value in the pretreatment temperature set to construct a random pretreatment temperature set. Next, the random number combination is packaged, encrypted, and stored in the first memory, while the random pretreatment temperature set is stored in the second memory. When encrypting the random number combination, an encryption cipher is set, including an encryption algorithm index code and an encryption key index code. This allows subsequent steps to decode the data by querying the corresponding encryption algorithm and key. Afterwards, retain the preprocessing concentration set and delete the preprocessing temperature set. The preprocessing temperature set can be deleted in two ways: either by setting a timeout period, starting the timer after the random preprocessing temperature set is constructed, and automatically deleting it after the timeout period; or by storing the preprocessing temperature set in a cache and deleting it by deleting cached data or replacing cached data.

[0040] Secondly, hot compressed gas is introduced into the pretreated raw rubber to transform it from a highly elastic state to a plastic state. The hot compressed gas can be heated compressed air, which, through the action of heat and oxygen, breaks down the large molecular chains of the raw rubber, homogenizes the molecular weight distribution, and improves plasticity by reducing the molecular weight and viscosity, thus achieving suitable flowability to meet the needs of further processing steps such as mixing and molding. In this step, the introduction of hot compressed gas affects the component concentration of the raw rubber, and the temperature changes relatively significantly. Since the raw rubber has already transformed into a highly fluid liquid state in this step, the temperature factor is incorporated into the measurement of the raw rubber concentration, and the concentration measurement is combined with temperature measurement to ensure precise temperature control and controllable concentration adaptability in subsequent processes.

[0041] Specifically, temperature values ​​during multiple raw rubber plasticizing processes are collected at the same first frequency, and the concentration values ​​of the corresponding components during the raw rubber plasticizing process are detected. The concentration values ​​and temperature values ​​are mapped according to the collection time points, and after matching, a plasticizing concentration-temperature set {C} is formed. i |T iThen, the random number combination stored in the first memory after being packaged and encrypted is called, and the random number combination data is obtained after decoding. The random numbers in the random number combination are repeatedly arranged and added to the temperature values ​​of the plasticizing concentration-temperature set respectively to construct a random plasticizing concentration-temperature set, and the random plasticizing concentration-temperature set is also stored in the second memory, that is, the temperature data with the same random encryption method is stored in the same memory. It should be noted that the concentration-temperature data is combined in the form of mapping and matching according to the acquisition time point to form a set. Concentration and temperature are highly correlated in the preparation process, and they work together to achieve the optimal process conditions. Considering the importance, correlation and confidentiality of the two data, this invention encrypts the temperature data in the implementation, and the encrypted temperature and concentration are combined as a whole, that is, the whole is also encrypted, realizing concentration encryption in the form of indirect concentration encryption. This effectively reduces the amount of calculation and ensures the correlation and confidentiality of the data. Furthermore, since the plasticizing time is usually different from the pretreatment time, the number of concentration / temperature values ​​collected based on the first frequency differs between the plasticizing and pretreatment stages. Consequently, the number of values ​​in the random number combination data also differs from the number of concentration / temperature values ​​collected during the plasticizing stage. Therefore, it is necessary to repeatedly arrange the random numbers in the random number combination. Specifically, the random numbers in the random number combination are repeatedly arranged according to the number of concentration / temperature values ​​collected during the plasticizing stage. Since the number of concentration and temperature values ​​collected during the plasticizing stage is the same, but the encryption of the random numbers only applies to temperature values, the random numbers in the random number combination are repeatedly arranged according to the number of temperature values ​​collected during the plasticizing stage. When the number of temperature values ​​collected during the plasticizing stage exceeds the number of random numbers, the random numbers are repeated and arranged sequentially until the number is the same as the number of temperature values ​​collected during the plasticizing stage. If the number does not exceed the limit, the corresponding random number is added to the temperature value in the plasticizing temperature set, and excess random numbers are discarded. If the two are the same, they are simply added together without increasing or decreasing the number. Similarly, the concentration detection method uses spectroscopy to detect the concentration components.

[0042] Next, the plasticized rubber solution has softened. The mixing process can effectively heat and stir the softened raw rubber, compounding agents, and auxiliary materials in the reactor. Through precise temperature measurement and control, the process of controlling the change in mixing concentration can be controlled, thereby ensuring the quality of mixing and improving the quality of the product.

[0043] Specifically, under preset conditions, the plasticized raw rubber, compounding agents, and auxiliaries are mixed to obtain a compounded rubber. The compounding agents and auxiliaries are uniformly mixed into the raw rubber. During the mixing process, the compounded rubber is subjected to real-time online concentration and temperature monitoring. Temperature values ​​are collected at multiple mixing stages at a first frequency, and the concentration values ​​of the corresponding components during the mixing process are also detected. The concentration and temperature values ​​are mapped according to the collection time points, and after matching, a compounded concentration-temperature set {HC} is formed. j |HT j}

[0044] During encryption, the number of temperature values ​​in the preprocessed temperature set is first converted into an even-numbered binary number. It should be noted that if the converted binary number has an odd number of bits, leading zeros are added to create an even-numbered binary number. This even-numbered binary number is then divided into two equal-sized preset binary numbers.

[0045] Then, the concentration and temperature values ​​in the mixing concentration-temperature set are converted into binary numbers for concentration and temperature, respectively. In existing methods, the combination of real code and additional code for encryption usually involves the real code being continuously interspersed within the additional code. This invention, however, inserts two preset binary numbers between the concentration and temperature binary numbers, respectively, forming encrypted binary concentration and temperature values. These binary concentration and temperature values ​​are then converted to decimal, forming the encrypted mixing concentration-temperature set, which is stored in a third memory. The positions where the two preset binary numbers are inserted between the concentration and temperature binary numbers can be selected in advance, ensuring the security of the positional data. This adds an extra layer of encryption, making the data more secure.

[0046] In this way, the three storage devices store different types of encrypted data. The data stored in the first storage device has a relatively low level of security, while the data stored in the second and third storage devices has a relatively high level of security. Therefore, different access permissions and access restrictions are set for the first, second, and third storage devices. Finally, when accessing concentration and temperature data, the user's permissions are verified. If the permission requirements are met, the encrypted data stored in the first, second, and / or third storage devices is fed back according to the access request. Then, the encrypted data is decrypted to complete the monitoring and analysis of concentration and temperature, and to control the preparation process under the desired environment and parameters.
