Abstract
Description
Technical Field
[0001] This application relates to the field of chemical testing technology, and in particular to a method, apparatus and adiabatic accelerated calorimeter for measuring adiabatic temperature rise data. Background Technology
[0002] Currently, adiabatic accelerated calorimeters are commonly used to measure the adiabatic temperature rise of substances. However, situations frequently arise where the tested substances are highly viscous systems, colloidal substances, or solid substances. Because adiabatic accelerated calorimeters often lack stirring or cannot achieve ideal mixing results for highly viscous systems, colloidal substances, or solid substances, and because these substances have limited heat transfer during testing (i.e., a temperature gradient exists within the measurement system, with different temperatures on the outside and inside of the substance), the measured data contains errors compared to the actual situation.
[0003] Taking a certain polyether polyol as the test substance as an example, following the experimental procedure of the adiabatic accelerated calorimeter described above, a certain amount of the polyether polyol is loaded into a test sphere. This test sphere is a special type configured in the adiabatic accelerated calorimeter, with a thermocouple slot at the bottom. An internal insertion tube is inserted into the center of the test substance. After connecting the test sphere to the internal insertion tube, the thermocouple of the adiabatic accelerated calorimeter is connected to the thermocouple slot, and an external thermocouple is connected. This external thermocouple is inserted into the center of the test substance through the internal insertion tube. Then, the top cover, insulation cavity, etc., are installed. After completing the above operations, the test software compatible with the adiabatic accelerated calorimeter is opened to conduct the experiment. The experimental results are as follows: Figure 1 As shown: The experiment will stop between 600 and 700 minutes because the set pressure limit has been exceeded to ensure experimental safety.
[0004] During the experiment, the inventors discovered that when using the adiabatic accelerated calorimeter, the outer temperature of the test sphere was 250°C, while the inner temperature was 260°C, a 10°C difference that severely affected the accuracy of the test results. Using the outer temperature for data processing resulted in unconservative results; using the inner temperature for data processing resulted in overly conservative results.
[0005] Given the problems in the above example, how to eliminate this influence and accurately measure the adiabatic temperature rise data of the system is an urgent problem to be solved. Summary of the Invention
[0006] The technical problem to be solved by this application is that there are large errors in the existing data for measuring the adiabatic temperature rise of high-viscosity substances, colloidal substances or solid substances. To this end, this application proposes a method, device and adiabatic accelerating calorimeter for measuring adiabatic temperature rise data.
[0007] To address the aforementioned technical problems, this application provides the following technical solution:
[0008] In a first aspect, this application provides a method for measuring adiabatic temperature rise data, used to measure the adiabatic temperature rise data of high-viscosity substances, colloidal substances, or solid substances, including:
[0009] Obtain the property information of the substance to be tested;

[0023] The method for measuring adiabatic temperature rise data described in some schemes, wherein f(m) b, C b m w C w m s C s The result is inversely proportional to the product of the mass of the test substance and the specific heat capacity of the test substance, directly proportional to the product of the mass of the test ball and the specific heat capacity of the test ball, and directly proportional to the product of the mass of the intermediate substance and the specific heat capacity of the intermediate substance.
[0024] In some schemes, the method for measuring adiabatic temperature rise data includes a formula for the thermal inertia correction value:

This eliminates the temperature gradient of the substance to be measured in the original measurement system, and ensures uniform temperature inside and outside the measuring sphere. The measurement results for homogeneous mixtures are more accurate and reliable.

[0050] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0051] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0053] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0054] This embodiment provides a method for measuring adiabatic temperature rise data, applicable to application scenarios where an adiabatic accelerated calorimeter is used to measure the adiabatic temperature rise data of high-viscosity systems, colloidal substances, or solid substances; wherein, for example... Figure 1 As shown, the method includes the following steps:
[0055] S10: Obtain the property information of the substance to be tested.
[0056] Among them, attribute information is used to determine the material properties and chemical properties of the substance to be tested, such as whether it is a high-viscosity system, a colloidal substance, or a solid substance, and solvents that will not react chemically with the substance to be tested.
[0057] S20: Determine the intermediate substance based on the property information of the substance to be tested.
[0058] The intermediate substance satisfies the following conditions: if the analyte is a high-viscosity system, the intermediate substance is used to reduce the viscosity of the analyte when mixed with it; if the analyte is a colloidal or solid substance, the intermediate substance is used to transform the analyte into a continuous phase when mixed with it; the intermediate substance does not react with the analyte, and the intermediate substance has stable chemical properties within the measurement temperature range.
[0059] Because the intermediate substance is also placed in the test sphere and heated by a thermocouple, the intermediate substance must have stable chemical properties within the test temperature range. This is to prevent the intermediate substance from undergoing decomposition reactions or producing other substances during the test, which could adversely affect the properties of the test substance and thus ensure the accuracy of the test results.
[0060] For example, when the analyte is a polyether polyol, the intermediate substance is water; when the analyte is an isocyanate, the intermediate substance is ethyl acetate; when the analyte is a monomer, the intermediate substance is a solvent corresponding to the monomer; when the analyte is isobutylene, the intermediate substance is n-hexane.
[0061] As shown in the example above, the intermediate substance and the analyte do not react. The intermediate substance merely reduces the viscosity of the analyte or makes it a continuous phase, making it more suitable for uniform mixing and eliminating the adverse effects of its heat transfer gradient.
[0062] S30: The homogeneous mixture obtained by mixing the intermediate substance and the substance to be tested is placed in the test ball of the adiabatic accelerated calorimeter to obtain the adiabatic temperature rise test result of the homogeneous mixture.
[0063] After the intermediate substance and the substance to be tested are mixed, as mentioned above, they have become a low-viscosity or continuous phase substance, so a homogeneous mixture can be obtained by stirring. After the homogeneous mixture is placed in the test sphere and the sealing operation is completed, the test result can be obtained using the software application corresponding to the adiabatic accelerated calorimeter, just like the test method in the prior art. This result is the adiabatic temperature rise test result of the homogeneous mixture.
[0064] Adiabatic heating refers to the temperature increase that can be achieved when a material undergoes complete exothermic reaction and the heat released during the reaction. In this specific experiment, the heat released by the test substance is absorbed not only by the test substance itself but also by the test sphere and intermediate substances; therefore, the results need to be corrected.
[0065] S40: Correct the adiabatic temperature rise test results of the homogeneous mixture based on the thermal parameter information of the intermediate substance, the substance to be tested, and the test ball, to obtain the adiabatic temperature rise test data of the substance to be tested.
[0066] Because the intermediate substance, the substance to be tested, and the material of the test sphere are all determined, the thermal parameters of these three substances are also determined, such as specific heat capacity and thermal inertia. Therefore, during the test, the temperature changes of the intermediate substance, the substance to be tested, and the test sphere can all be determined based on their respective thermal parameters. This allows us to determine how much of the heat released by the substance to be tested was absorbed by the intermediate substance and the test sphere, and how much was absorbed by the substance itself. Thus, we can determine the adiabatic temperature rise test data of the substance to be tested.
[0067] In the above embodiments, when measuring the adiabatic temperature rise data of high-viscosity substances, colloidal substances, or solid substances, an intermediate substance is added to the original measurement system. The intermediate substance is mixed with the substance to be measured, which reduces the viscosity of the high-viscosity substance or makes the colloid and solid become a continuous phase, eliminating the temperature gradient of the substance to be measured in the original measurement system. The temperature inside and outside the measuring sphere is uniform, and the measurement results for homogeneous mixtures are more accurate and reliable. Then, the adiabatic temperature rise test results of the homogeneous mixture are corrected based on the thermal parameter information of the intermediate substance, the substance to be measured, and the test sphere, to obtain the adiabatic temperature rise test data of the substance to be measured. After actual experimental verification, the adiabatic temperature rise test data of the substance to be measured obtained after correction has the required accuracy.
[0068] Specifically, step S40 may include the following steps: obtaining the mass and specific heat capacity of the intermediate substance; obtaining the mass and specific heat capacity of the test ball; obtaining the mass and specific heat capacity of the substance to be tested; determining the thermal inertia correction value of the substance to be tested based on the mass and specific heat capacity of the intermediate substance, the mass and specific heat capacity of the test ball, and the mass and specific heat capacity of the substance to be tested; and multiplying the adiabatic temperature rise test result of the homogeneous mixture with the thermal inertia correction value to obtain the adiabatic temperature rise test data of the substance to be tested.
[0069] Regarding the heat absorption and release of a substance and temperature changes, the specific heat capacity has the greatest impact. Therefore, this method obtains the mass and specific heat capacity of the intermediate substance, the substance to be tested, and the test sphere to determine the influence of the test sphere and the intermediate substance on the adiabatic temperature rise data of the substance to be tested. The aforementioned influence relationship or influence function can be determined through calibration experiments. The adiabatic temperature rise test data of the substance to be tested is obtained by multiplying the adiabatic temperature rise test results of the homogeneous mixture by the thermal inertia correction value.
[0070] In this application, the thermal inertia correction value of the substance under test is determined by the following function, including:
[0071] Phi'=1+f(m b, C b m w C w m s C s );
[0072] Where, f(m) b C b m w C w m s C s ) indicates that it contains parameter m b C b m w C w m s C s The function can be determined through calibration experiments. Where m... b C represents the mass of the test ball. b The specific heat capacity of the test sphere is represented by m. w C represents the mass of the intermediate substance. w m represents the specific heat capacity of the intermediate substance. s C represents the mass of the substance being tested. s This indicates the specific heat capacity of the substance being tested.
[0073] Furthermore, the f(m) b C b m w C w m s C sThe result is inversely proportional to the product of the mass and specific heat capacity of the test substance, directly proportional to the product of the mass and specific heat capacity of the test sphere, and directly proportional to the product of the mass and specific heat capacity of the intermediate substance. That is, the product of the mass and specific heat capacity of the test substance is used as the denominator, and the products of the mass and specific heat capacity of the test sphere and the intermediate substance are used as the numerators. Preferably, the formula for the thermal inertia correction value is expressed as:
[0074]
[0075] The final adiabatic temperature rise test data of the substance to be tested are as follows:
[0076] δT (Phi=1) =δT (Phi>1) ×Phi';
[0077] δT (Phi=1) This represents the adiabatic temperature rise test data of the substance under test, δT. (Phi>1) This represents the adiabatic temperature rise test result of a homogeneous mixture, where Phi' represents the correction value for the thermal inertia of the substance being tested.
[0078] In the above scheme, the unit of thermal inertia is "1", the unit of mass is "g", the unit of specific heat capacity is "J / gK", and the unit of adiabatic temperature rise test data is "K", where K represents Kelvin.
[0079] The above method was used to test a certain polyether polyol. Water was chosen as the intermediate substance. Solutions of different concentrations were prepared by mixing the test substance with water, and the experiments were conducted following the same steps. As shown in Table 1, three experimental samples were obtained by mixing water and the polyether polyol, corresponding to concentrations of 50%, 60%, and 70%. The test results are as follows: Figure 3-5 As shown in the table below, the corrected adiabatic temperature rise is approximately 250-260℃. This temperature value can be calculated using Kelvin. Assuming the specific heat capacity of the substance being tested is 2 J / g·K, the total heat release is approximately 500-520 J / g.
[0080] Table 1. Experimental data and results of a certain polyether polyol at different concentrations.
[0081]
[0082] When testing a pure polyether polyol, DSC was used at different heating rates, and the test results were processed using AKTS software. The results are as follows: Figure 6As shown in the figure, the heat release is in the range of 507±12J / g. The result of the correction using the adiabatic calorimeter method coincides with this result, thus verifying the accuracy of the proposed solution.
