The high-low Temperature Test Chamber can be used to test the performance of plastic doors and windows in high-low temperature environments, mainly including UV resistance, aging resistance, impact resistance, etc.
Plastic doors and windows need to undergo high-low temperature resistance tests, mainly to evaluate the changes in their physical and chemical properties under different temperature conditions to ensure that they can withstand various environmental conditions while maintaining the stability and reliability of their quality and performance. Through high-low temperature resistance tests, important indicators such as strength, stiffness, wear resistance, corrosion resistance and dimensional stability of plastic doors and windows can be evaluated at different temperatures, so as to ensure that they can work normally and have high durability in various environments sex. In addition, plastic doors and windows may expand, soften, and deform at high temperatures, while they may become brittle or crack at low temperatures. Therefore, high-low temperature resistance tests can also evaluate the reliability and reliability of plastic doors and windows under different temperature conditions. safety. The high-low temperature resistance test can ensure that plastic doors and windows have stable performance and quality in various environments, and can meet the safety and durability requirements in construction projects.
experiment procedure
Here are the test steps:
Place the plastic doors and windows to be tested in the high-low Temperature Test Chamber, and set the temperature of the Test Chamber to the specified high or low temperature.
Raise the temperature of the Test Chamber to the specified temperature and keep it for a period of time. Generally, you can choose a high temperature of 50°C and a low temperature of -40°C. The holding time is determined according to actual needs.
After the holding time is over, return the temperature of the Test Chamber to normal temperature, and observe the performance of the plastic doors and windows to be tested, such as deformation, cracking, color difference, etc.
If you need to test the aging resistance, you can repeat the high-low temperature cycle test on plastic doors and windows to observe the changes in performance.
If you need to test the impact resistance, you can perform a simulated impact test in a high-low Temperature Test Chamber to observe the cracking of plastic doors and windows.
Finally, according to the experimental results, it is judged whether the high-low temperature performance of the plastic doors and windows to be tested meets the requirements.
