The constant temperature and humidity Test Chamber is widely used in the heat and humidity resistance test of automotive refinish paint. The Test Chamber can simulate a high temperature and high humidity environment, and is used to test the resistance of automotive refinish paint in this environment.
application:
Car refinish is a paint used to repair scratches and damage to the body of the car. Automotive refinish paints are easily affected by moisture, heat and other factors in high-temperature and high-humidity environments, resulting in problems such as discoloration, cracking, and peeling of the paint surface, which in turn affects the quality and reliability of the product. The constant temperature and humidity Test Chamber can simulate this high-temperature and high-humidity environment for testing the resistance of automotive refinish paint. Specific applications include:
Test the resistance and longevity of automotive refinish paints in high temperature and high humidity environments.
Test the color and gloss of automotive refinish paints in high temperature and high humidity environment.
Evaluate performance and functionality of automotive refinish coatings against specifications.
experiment procedure:
According to the requirements of the heat and humidity resistance test for automotive refinish paint, select a suitable constant temperature and humidity Test Chamber for testing.
Apply automotive refinish paint samples on a clean, dry and flat test panel, and place the test panel in a constant temperature and humidity Test Chamber.
Set the temperature and humidity parameters of the Test Chamber. Typically, the temperature is set between 60°C and 80°C, and the humidity is set around 90%RH.
Let the automotive refinish paint sample be exposed to a constant temperature and humidity environment for a certain period of time, usually 24 hours to 96 hours.
During the run, regularly check the condition of the automotive refinish paint samples, including color and gloss.
After the test, take out the car refinish paint samples, and conduct performance testing and analysis to evaluate whether the heat and humidity resistance of the car refinish paint meets the requirements.
NBCHAO reminds you: When conducting the heat and humidity resistance test of automotive refinish paint, the appropriate test parameters and test time should be selected according to the requirements and specifications of the automotive refinish paint, so as not to cause too much interference to the accuracy and reliability of the test results Influence.
