Description

Technical Field

[0001] The present invention belongs to the technical field of power systems, relates to the field of performance prediction of protective materials, and in particular to a method for predicting the fire resistance of materials based on material crystallinity and related devices. Background Art

[0002] With the development of modern industry and technology, the fireproof performance of fireproof materials plays a vital role in many fields; for example, such as energy systems, urban pipeline tunnels, industrial facilities and high-voltage power transmission. The main function of fireproof materials is to keep them from burning when a fire occurs while ensuring the integrity of the overall structure and ensuring the safe and reliable operation of equipment and lines. With the diversification of application environments and increasingly complex working conditions, the fireproof performance of fireproof materials has been challenged. How to effectively evaluate and predict the fireproof performance of materials has become a technical problem that needs to be solved urgently.

[0003] At present, the fire resistance performance test methods of existing materials usually require long-term actual use tests or simulation tests in laboratory environments, which have defects such as long time consumption and high cost, and it is difficult to accurately predict the performance of materials under changing environmental conditions. In addition, most of the existing fire resistance performance evaluation methods focus on macroscopic parameters, ignoring the microstructure of the material, especially the profound influence of crystallinity on the fire resistance of the material. Explanatoryally, the fire resistance of the material is closely related to its microstructure, especially the crystallinity of the material, which has a direct impact on its performance. Further explanatory, crystallinity refers to the proportion of the crystalline part in the material, which has a direct impact on the molecular arrangement and electronic motion characteristics of the material; generally speaking, materials with high crystallinity usually have more regular molecular arrangements, and the thermal stability of the material is usually better; the atomic arrangement in the crystalline structure is more regular and compact, which enables the material to better resist thermal expansion and thermal shock at high temperatures; therefore, fire-resistant materials with high crystallinity usually have better high temperature resistance. Fireproof materials with high crystallinity can effectively isolate the spread of heat, maintain structural integrity at higher temperatures, are not easily softened or melted, and can inhibit the further spread of fire. On the contrary, materials with low crystallinity may cause degradation of thermodynamic, mechanical, and electrical properties due to irregular molecular arrangement and more internal defects.

[0021] See also Figure 1 , a method for predicting the fire resistance of a material based on the crystallinity of the material provided by an embodiment of the present invention comprises the following steps: Step 1, obtaining crystallinity data of the material to be predicted for fire resistance; Step 2, based on the crystallinity data of the material to be predicted for fire resistance obtained in step 1, a prediction is performed using a pre-built prediction model to obtain a fire resistance prediction result of the material to be predicted for fire resistance; The prediction model is based on the known crystallinity data of the material to be predicted for fire resistance and the fire resistance test results corresponding to the crystallinity data, and a mathematical correlation model between the obtained crystallinity and fire resistance is established using a statistical analysis method.

[0022] In the technical solution of the embodiment of the present invention, the mathematical correlation model is a functional relationship between the crystallinity of the material and the fire resistance performance established through statistical analysis.

[0024] In addition, the prediction method based on material crystallinity disclosed in the embodiment of the present invention also has far-reaching theoretical significance and practical value. It provides a solid theoretical basis for the design of new high-fire retardant materials, points out the research direction for material scientists and engineers, and helps to promote innovation and development in the fields of material science and fire protection. By deeply exploring the intrinsic connection between material crystallinity and fire-retardant material performance, we can better understand and utilize the characteristics of materials, opening up a broader space for future material research and development and application.

[0025] In the preferred technical solution of the embodiment of the present invention, the fire resistance test results of the material include one or more of bending strength, elastic modulus, thermal conductivity and oxygen index fire resistance.

[0026] See also Figure 2 In a preferred embodiment of the present invention, based on the crystallinity data of the material and the fire resistance test results, the steps of establishing a mathematical correlation model between crystallinity and fire resistance using a statistical analysis method specifically include: Step 1), obtaining the crystallinity data of the material; In a specific exemplary technical solution, techniques such as X-ray diffraction (XRD), differential scanning calorimetry (DSC) or Fourier transform infrared spectroscopy (FTIR) may be used to obtain the crystallinity data of the material.

[0027] Step 2), fire performance test; In a specific exemplary technical solution, the fire resistance performance of the material is tested under different environmental conditions (such as temperature, humidity, electric field strength, etc.) to obtain data such as the material's fire resistance bending strength, elastic modulus, thermal conductivity or oxygen index.

[0028] Step 3) Establishment of correlation model; In a specific exemplary technical solution, based on the crystallinity data of the material and its fire resistance test results, statistical analysis methods (such as regression analysis, machine learning, etc.) are used to establish a mathematical correlation model between crystallinity and fire resistance.

[0029] Step 4) prediction and verification; In a specific exemplary technical solution, the mathematical correlation model established in step 3) is used to predict the fire resistance of materials with different crystallinity, and the accuracy and applicability of the model are verified through experiments.

[0030] In the preferred technical solution of the embodiment of the present invention, by accurately characterizing the crystallinity characteristics of the material and comprehensively considering the fire resistance performance of the material under variable environmental conditions such as different temperatures, humidity, and electric field strengths, a quantitative mathematical correlation model between the crystallinity of the material and its fire resistance is established using data analysis and modeling techniques. This model can reveal the specific influence of changes in crystallinity on fire resistance, and can provide a scientific basis for the prediction and evaluation of the fire resistance of the material.

[0031] In a specific embodiment of the present invention, a method for predicting the fire resistance of a material based on the crystallinity of the material is provided, and the steps are as follows: Step 1: Material crystallinity characterization process, including: Use XRD, DSC or FTIR equipment to characterize the crystallinity of the target material, and obtain the crystal phase content and molecular arrangement order data by measuring the sample; For multiple groups of samples, the crystallinity of the samples is controlled by adjusting the preparation process (such as changing factors such as temperature, cooling rate or external stress) to form a group of materials with different crystallinity. The crystallinity of each sample is measured by characterization equipment and the corresponding data is recorded.

[0032] Step 2: Fire performance test process, including: The fire retardant performance test of the material will be carried out under different environmental conditions. In order to evaluate the fire retardant effect of the material in actual use, mechanical testing equipment and thermodynamic testing system are used. During the test, the ambient temperature, humidity and applied voltage are adjusted to measure the key fire retardant performance indicators of the material under different conditions, such as bending strength, elastic modulus, thermal conductivity, oxygen index fire retardant, etc. When designing the experiment, the test can be carried out in stages; for example, the bending strength, elastic modulus, thermal conductivity, oxygen index fire resistance, etc. of the material can be measured at room temperature first, and then the temperature and humidity can be gradually increased while performing performance tests to obtain complete environmental response data.

[0033] Step 3: Mathematical correlation model establishment and programming implementation process, including: After obtaining the material crystallinity and fire performance test data, data analysis software (including but not limited to MATLAB, Python, etc.) is used to train algorithms such as regression analysis or machine learning. In the specific exemplary technical solution, the model can select algorithms such as multivariate regression, random forest or neural network, including but not limited to the above algorithms.

[0034] When processing data, first use the crystallinity as the model input, and test the fire performance of materials with the same crystallinity. The test results are used as the output results of the corresponding independent variable model. The model is trained with real test data, and the above operation is repeated to test the fire performance of materials with different crystallinity, optimize the training model, and improve the model accuracy. In this process, different fire performance indicators are used as model dependent variables, and the model is trained and tested to correct its prediction level; in order to improve the accuracy of the model, a variety of variables (such as environmental conditions, etc.) can be introduced to optimize the prediction effect. After the model is trained, in actual use, the crystallinity of the material is used as the model input, and the corresponding fire performance indicator is used as the model output. The input and output are connected through multiple regression, random forest or neural network, etc., including but not limited to the above algorithms.

[0035] Step 4: Model validation and optimization process, including: To verify the accuracy of the model, we can compare the experimental and predicted results. Select a batch of samples that did not participate in the model training, measure their crystallinity, and use the model to predict their fire resistance. Then, conduct actual fire resistance tests on these samples and compare the errors between the predicted values ​​and the experimental values. If the predictions are consistent with the experimental results, it means that the model has a high prediction accuracy. If there is a large deviation, it is necessary to further optimize the model or supplement the experimental data to improve the accuracy and wide applicability of the prediction.

[0036] In a specific application embodiment of the present invention, in a certain electrical equipment manufacturing company, the R&D department is developing a new type of polymer fireproof material for use as a fireproof layer for high-voltage cables; in order to ensure the reliability of the material in practical applications, its fireproof performance needs to be accurately predicted. Since the crystallinity of the material has a significant impact on the fireproof performance, the fireproof performance prediction method based on the crystallinity of the material provided by the present invention includes the following steps: Step (1), obtaining crystallinity data of the material to be predicted for fire resistance, comprises: Step (1.1), select the test method: Considering the characteristics of polymer materials, X-ray diffraction (XRD) is selected as the main method to obtain crystallinity data. XRD can provide detailed information about the crystal phase content and molecular arrangement order of the material.

[0037] Step (1.2), implementing the test: preparing the polymer material to be tested; testing the sample using an X-ray diffractometer to obtain a diffraction pattern; analyzing the diffraction pattern to calculate the crystallinity data of the material, which may include indicators of crystal phase content and orderliness of molecular arrangement.

[0038] Step (2), building a prediction model, includes: Step (2.1), collect sample data: prepare a series of polymer material samples with different crystallinity; perform XRD test on each sample to obtain crystallinity data.

[0039] Step (2.2), conduct fire resistance test: select the fire resistance index; conduct fire resistance test on each sample under different preset conditions (such as temperature, humidity, etc.) and record the test results.

[0040] Step (2.3), model training and verification: organize the collected crystallinity data and fire test results to form a training data set; select the multivariate regression algorithm as the model training method; use the training data set to train the multivariate regression model, and adjust the model parameters so that the model can accurately reflect the relationship between crystallinity and fire resistance indicators; use cross-validation and other methods to verify the model to ensure the accuracy and stability of the model; when the model reaches the preset convergence condition, obtain the trained mathematical association model and use it as a prediction model.

[0041] Step (3), fire resistance performance prediction, includes: inputting the crystallinity data of the new material into the trained prediction model; the model outputs the fire resistance prediction result of the new material based on the input crystallinity data; based on the prediction result, evaluating whether the fire resistance performance of the new material meets the design requirements; if the prediction result does not meet the expectation, the material formula or processing technology can be adjusted, and then retesting and predicting until a satisfactory result is obtained.

[0042] In summary, by adopting the fire retardant performance prediction method based on material crystallinity of the present invention, the fire retardant performance of the newly developed polymer fire retardant material can be accurately predicted, thereby effectively shortening the material research and development cycle, reducing research and development costs, and improving the reliability and application performance of the material. The method of the present invention can provide strong technical support for the material research and development of the fire protection manufacturing industry.

[0043] In the above application embodiment, further exemplary explanations on constructing a prediction model are as follows: Collect sample data: Select a series of polymer material samples with different crystallinity, which should cover a wide range from low crystallinity to high crystallinity to ensure the generalization ability of the model; use a high-precision X-ray diffractometer to test each sample. During the test, ensure that the sample surface is flat and free of contamination to obtain an accurate diffraction pattern. By analyzing the diffraction pattern, calculate the crystallinity data of each sample, including the crystal phase content and the ordered index of molecular arrangement.

[0044] Conduct fire resistance test: determine fire resistance as the key indicator for evaluating fire resistance; set different test conditions, such as temperature (e.g., 25°C, 50°C, 75°C), humidity (e.g., 20%RH, 50%RH, 80%RH), and electric field strength (e.g., 10kV / mm, 20kV / mm, 30kV / mm) to comprehensively evaluate the fire resistance of samples under different environments. Under the set conditions, each sample is subjected to a fire resistance test, and the thermodynamic changes during the test and any abnormal phenomena are recorded. Furthermore, each sample is tested at least three times under each condition to ensure the reliability of the test results.

[0045] Model training and verification: The collected crystallinity data and fire test results are sorted to form a training data set containing multiple samples. Each sample includes the crystallinity data (crystalline phase content and molecular arrangement order) of the sample and the fire test results under different conditions. Based on the characteristics of the data and the analysis requirements, the multivariate regression algorithm is selected as the model training method. The multivariate regression algorithm can handle the relationship between multiple independent variables (such as crystallinity and test conditions) and the dependent variable (fire resistance), and is suitable for building a prediction model. The multivariate regression model is trained using the training data set. During the training process, the model parameters (such as regression coefficient, intercept, etc.) are adjusted to enable the model to accurately reflect the relationship between crystallinity and fire resistance. Optimization algorithms such as gradient descent are used to minimize the prediction error and improve the fitting effect of the model. The model is verified using methods such as cross-validation. The training data set is divided into several subsets, and one of the subsets is used as the validation set in turn, and the remaining subsets are used as the training set for model training. The accuracy and stability of the model are evaluated by comparing the prediction results of the model on the validation set with the actual test results. If the prediction error of the model is within an acceptable range, the model is considered to have converged. When the model reaches the preset convergence conditions (such as the prediction error is less than a certain threshold, the model parameter changes tend to be stable, etc.), a trained mathematical correlation model is obtained. The model can predict the fire resistance of polymers under different conditions based on the input crystallinity data.

[0046] For example, the model might look like this: Fire performance = f(crystalline phase content, molecular arrangement order, temperature, humidity, electric field strength); in, f is a function trained by a multivariate regression algorithm.
