How do paints perform high-low temperature resistance tests?

The high-low Temperature Test Chamber can be used to test the high-low temperature resistance of paint. In the high-low temperature test, the sample is placed in a high-low temperature test box, and the temperature change in the actual environment is simulated by controlling the temperature and humidity changes in the box, so as to evaluate the durability and cold resistance of the paint at different temperatures.

application background

The reason why the paint needs to be tested for high-low temperature resistance is because the paint will be affected by different temperatures during use. If the paint cannot withstand the high-low temperature environment, a series of problems will appear, such as cracking, peeling, aging, etc. Especially in low temperature environment, the paint is also prone to problems such as hardening and reduced adhesion. Through the high-low temperature resistance test, the thermal stability and cold resistance of the paint can be evaluated, and its performance at different temperatures can be understood, so as to provide a scientific basis for the selection and use of the paint.

experiment procedure

Prepare samples: Prepare the paint samples to be tested and apply them on the corresponding test panels according to the standards.

Set the test conditions: put the sample into the high-low Temperature Test Chamber, set the temperature and humidity parameters according to the selected standard, and set the test time to the required time.

Conducting the test: After starting the test, the high-low temperature test box will automatically control the temperature and humidity changes in the box, and record the reaction and changes of the samples.

Observe and evaluate the samples: After the test, take out the samples and observe their surface and performance changes, compare the test results at different temperatures, and evaluate the durability and cold resistance of the paint in high-low temperature environments.

North and South Chao reminds you: Different standards and test requirements may require different test conditions and steps, so before conducting the paint high-low temperature resistance test, it is necessary to carefully study the selected standard and conduct the test according to the standard requirements.
