Automobile original paint needs to be tested for high-low temperature resistance, because during the use of the car, the vehicle will experience various temperature environments, including high temperature, low temperature, humidity and so on. If the original car paint has not passed the high-low temperature resistance test, it may fall off, crack, and change color under extreme temperatures, which will affect the appearance and protection of the vehicle.
The purpose of the high-low temperature resistance test is to evaluate the durability of the original car paint in various temperature environments to ensure that it can maintain its function and appearance in various environments. In this test, the car's original paint is placed in a high-temperature cabinet and a low-temperature cabinet, and exposed to different temperature and humidity conditions for a certain period of time. Through these tests, it is possible to determine the performance and protective effect of the original car paint under extreme temperatures, so as to formulate corresponding improvement plans and measures to ensure that the car maintains a good appearance and protective effect during its service life.
In the automotive industry, high-low Temperature Test Chambers are widely used for testing the high-low temperature resistance of automotive original paint. The following is the application and test steps of this equipment in the high-low temperature resistance test of automobile original paint:
application
The high-low temperature resistance of the original car paint has an important impact on the quality and appearance of the car body coating. The high-low Temperature Test Chamber can simulate the use environment of the vehicle under different climatic conditions, and test the heat resistance, cold resistance and weather resistance of the paint film. .
experiment procedure
Set test conditions according to relevant standards or customer requirements, including test temperature range, heating/cooling rate, test time and other parameters.
Spread the paint film sample to be tested on the sample holder, and pay attention to avoid surface scratches or deformations that may affect the test results.
Put the sample rack into the high-low Temperature Test Chamber, and start the equipment to start the heating or cooling test.
Observe the changes on the surface of the sample, such as cracks, peeling, etc., within the set test time.
After the test is completed, the samples are taken out for inspection and evaluation, and the evaluation criteria can be based on relevant industry standards or customer requirements.
NBCHAO reminds you: when conducting high-low temperature tests, test conditions should be set according to standards or customer requirements to ensure the reliability and accuracy of test results. At the same time, it is necessary to avoid damage or errors to the equipment and samples during the operation, so as to ensure the smooth progress of the test.
