[0002] In the cold winter, it is common for water pipes to freeze and crack due to low temperatures, which not only brings inconvenience to residents' lives, but also often leads to waste of water resources and property losses. In order to deal with this problem, a variety of anti-freeze cracking water pipes have appeared on the market. These pipe materials usually improve their anti-freeze performance by adding specific anti-freeze ingredients or using special production processes. However, how to accurately evaluate the anti-freeze performance of these anti-freeze cracking water pipes has become an urgent problem to be solved.

[0003] Traditional testing methods mostly rely on intuitive physical observation, such as placing the sample in a low-temperature environment and judging its antifreeze performance by observing whether cracks appear. Although this method is intuitive, it lacks precision and repeatability, making it difficult to quantitatively evaluate the antifreeze performance of water pipes. In addition, the antifreeze performance of water pipe samples from different batches and different manufacturers may vary significantly. Therefore, a more scientific and accurate testing method is needed to evaluate its antifreeze performance. Summary of the invention

According to industry standards and user needs, set the qualified standard for antifreeze performance, compare the calculated antifreeze performance with the qualified standard, and determine whether the unknown water pipe sample is qualified.

[0008] Furthermore, in step S3, the mathematical model takes into account factors such as sample material, production process and pretreatment conditions that affect the antifreeze performance, and considers these factors as additional variables of the model.

[0009] Furthermore, in step S4, the calculation of the antifreeze performance also includes using a model to predict the antifreeze cracking performance of the sample under extreme temperature conditions to evaluate the reliability of the sample under extreme environments.

[0010] Furthermore, in step S5, the qualification criteria also include a comprehensive evaluation of the antifreeze performance of the sample under different temperature gradients to ensure that the sample can maintain good antifreeze cracking performance over the entire temperature range.

[0024] The present application is described below in conjunction with the drawings in the present application.

[0025] Embodiment 1: Figure 1 As shown, a method for testing the antifreeze performance of a frost-proof water supply pipe of the present invention specifically comprises the following steps: S1. Select the anti-freeze cracking water supply pipe samples to be tested, ensure that the length and diameter parameters of the samples are consistent, and pre-treat the samples to ensure the accuracy of the test results; Sample selection: 10 anti-freeze crack water supply pipes were randomly selected from the production line as the test samples, ensuring that all samples were 2 meters in length and DN20 in diameter to eliminate the impact of size differences on the test results; Sample pretreatment: Cleaning: Use anhydrous ethanol or acetone to thoroughly clean the sample surface to remove impurities such as oil, dust, etc. to ensure that the sample surface is clean and pollution-free; Drying: Place the cleaned sample in a well-ventilated environment to dry naturally, or use a hair dryer to dry it to avoid the influence of residual moisture on the test results; Inspection: Before and after pretreatment, use a vernier caliper to recheck the length and diameter of the sample to ensure that the sample size meets the test requirements; Pretreatment environment: The pretreatment process should be carried out at room temperature to ensure that the ambient temperature is stable and avoid the impact of temperature fluctuations on sample performance. At the same time, the ambient temperature and humidity during the pretreatment process should be recorded for subsequent data analysis; Pretreatment records: Keep detailed records of the pretreatment process of each sample, including cleaning time, drying method, inspection results, etc., to ensure the traceability and accuracy of the test.

[0026] S2. Place the treated samples in a set low temperature environment, observe and record the anti-freeze cracking performance of the samples at various temperatures; Use a programmable low temperature test chamber to set a series of decreasing temperature points, for example, starting from -5°C and decreasing by 5°C until -40°C or lower. Keep each temperature point constant to ensure that the sample is fully exposed to the temperature so as to observe its anti-freeze cracking performance; Place the pre-treated samples horizontally on the bracket in the low-temperature test chamber, ensuring that the samples do not touch each other to avoid mutual influence. The samples should be evenly distributed in the test chamber to ensure uniform temperature distribution and improve the accuracy of the test results; At each temperature point, use a high-definition camera or microscope to observe the surface and interior of the sample, record the cracking time and crack length. When observing, pay attention to recording the shape, direction and number of cracks. This information is helpful for analyzing the anti-freeze cracking mechanism of the sample. Record the observation results at each temperature point, including temperature, cracking time, crack length and any abnormal phenomena, such as sample deformation, color change, etc.; During the entire test process, keep the humidity in the low-temperature test chamber constant to avoid the influence of humidity changes on the test results. Regularly check the temperature distribution in the test chamber to ensure temperature uniformity and avoid local overheating or overcooling. The observation results were organized into tables or graphs for subsequent analysis and comparison, and the relationship between cracking time and temperature, as well as the trend of crack length changing with temperature, were analyzed to provide data support for establishing a mathematical model of antifreeze performance.

[0027] S3. Using the characteristics of the water pipe samples under various low temperature conditions, which show a certain regularity in their anti-freeze cracking performance, a mathematical model of anti-freeze performance is established. The model is constructed based on the relationship between cracking time, crack length parameters and temperature; Following the above steps, place the treated samples in a series of decreasing low temperature environments and record the cracking time and crack length at each temperature point; ensure that at least 3-5 samples are tested at each temperature point to improve the reliability and statistical significance of the data; Clean the collected data, remove outliers or invalid data, and standardize the data to ensure comparability between different parameters; Select the mathematical model linear regression to describe the relationship between cracking time, crack length and temperature. Based on the collected data, use statistical software to fit the model. By adjusting the model parameters, optimize the model fit to ensure that the model can accurately reflect the regularity and trend in the data. According to the model fitting results, the parameters that contribute most to the model are selected as the components of the final model, and the stability and reliability of the parameters are evaluated to ensure that the model has consistent prediction performance under different conditions; Use a data set that is not involved in model construction to validate the model, evaluate the model's prediction accuracy and generalization ability, and evaluate the accuracy and reliability of the model by comparing the difference between the predicted value and the actual value; According to the verification results, make necessary adjustments and optimizations to the model to improve its predictive performance and practicality, and record the process and results of model optimization for subsequent analysis and improvement; The basic form of the linear regression model can be expressed as: Y = β0 + β1T + E, where: Y is the dependent variable (such as cracking time or crack length); T is the independent variable (temperature); β0 is the intercept term, which represents the expected value of Y when T = 0; β1 is the slope coefficient, which represents the change in Y when the temperature changes by one unit; E is the error term, which represents the influencing factors not captured by the model; Before performing linear regression analysis, the data needs to be preprocessed: check and remove data points that are significantly out of the normal range. If the order of magnitude of the cracking time and crack length are very different, consider standardizing them to the same scale, such as using Z-score standardization; The model is used to predict the expected cracking time or crack length of the water pipe sample under new temperature conditions: Y=β0+β1T.

[0028] S4, after the water supply pipe sample to be tested is treated according to the same pretreatment steps, it is placed in a preset low temperature environment, its anti-freeze cracking performance is recorded, and it is substituted into the established mathematical model to calculate the anti-freeze performance of the sample at various temperatures; According to the detailed description of step S1 in the first embodiment, the water supply pipe sample to be tested is pre-processed; According to the detailed description of step S2 in Example 1, the temperature of the low temperature test box is set, and each temperature point is ensured to be kept constant so as to observe the anti-freeze cracking performance of the sample; According to the detailed description of step S3 in Example 1, using the established antifreeze performance mathematical model, the cracking time and crack length data recorded in step S2 are substituted into the model; Analyze the changing trend of the antifreeze performance value of the samples at different temperature points, evaluate whether the antifreeze performance of the samples meets expectations, and compare the antifreeze performance of the samples with the performance of known materials to further verify the accuracy of the model; Set qualified standards for antifreeze performance according to industry standards and user needs, which usually involve some specific performance indicators, such as maximum cracking time, maximum crack length or minimum antifreeze performance value at a specific temperature; The calculated antifreeze performance value is compared with the qualified standard to determine whether the unknown water supply pipe sample is qualified. If the antifreeze performance of the sample at all test temperature points meets the qualified standard, it is judged to be qualified; otherwise, it is judged to be unqualified, and further analysis of the reasons and improvement measures are required.

[0029] S5. According to industry standards and user needs, set the qualified standard of antifreeze performance, compare the calculated antifreeze performance with the qualified standard, and determine whether the unknown water supply pipe sample is qualified; First, obtain the specific requirements for the anti-freeze performance of anti-freeze crack water supply pipes by consulting relevant industry standards. These standards usually specify the allowable range of key parameters such as cracking time and crack length at different temperatures; At the same time, communicate with users to understand their specific requirements for the antifreeze performance of water supply pipes, including specific use environment, temperature range, service life, etc. According to the collected industry standards and user needs, combined with the actual situation, the qualified standards for antifreeze performance are set, including: Maximum cracking time: the longest time required for a sample to crack under a given low temperature environment; Maximum crack length: the maximum allowable length of the crack after the sample is cracked; Temperature range: the temperature range in which the sample can maintain antifreeze performance; It should be noted that the setting of qualification standards should be scientific and reasonable, meeting both industry requirements and actual user needs; According to the method described in the previous steps, the water supply pipe sample to be tested is pretreated and tested at low temperature, and then substituted into the established mathematical model to calculate the antifreeze performance value of the sample at various temperatures; Compare the calculated antifreeze performance value with the set qualified standard. If the antifreeze performance of the sample at all test temperature points meets the qualified standard, it is judged as qualified; otherwise, it is judged as unqualified; Record the determination results, including sample number, test temperature, antifreeze performance value, determination results and other information; If the sample is judged to be unqualified, the reasons should be further analyzed, such as problems in material quality, production process, etc., and improvement measures should be proposed; The judgment results and improvement measures will be fed back to relevant departments and users so that they can understand the antifreeze performance of the samples and take corresponding measures.

[0030] Through strict pretreatment steps such as cleaning, drying and dimensional inspection, the consistency of all test samples and the accuracy of the test are ensured. The use of programmable low-temperature test chambers and standardized test procedures reduces variables in the test process and improves the accuracy and repeatability of the test. By testing at multiple decreasing temperature points, the anti-freeze cracking performance of the samples in different low-temperature environments can be fully evaluated. Detailed observation records, such as cracking time, crack length, crack morphology, etc., provide rich data support for in-depth analysis. The anti-freeze performance mathematical model is established using the collected data, which can quantify the relationship between temperature and cracking time and crack length, providing a scientific basis for prediction and optimization.
