Procedure of detection method
The following is the performance of polyurethane waterproof coating to be tested and its testing steps:
Construction performance: Use construction performance testing equipment to test the fluidity, brushability, drying time and other construction performance of the coating, and record the test results.
Weatherability: Test the weatherability of the coating using a xenon lamp aging chamber or a spectral radiation chamber, and record the test results.
Water resistance: Use water penetration test equipment and soaking test equipment to test the water resistance of the coating, and record the test results.
Bond strength: The coating adhesion to the substrate was tested using the delimiting tester and the stripping tester, and the test results were recorded.
Impact resistance: The impact testing machine is used to test the impact resistance of the coating, and the test results are recorded.
Aşınma direnci: Wear testing machine is used to test the wear resistance of the coating, and the test results are recorded.
Color and luster: Test with color difference meter and luster meter under standard light source and record the test results.
Bazı özel kaplamalar için, test için başka alet ve ekipmanların kullanılması gerekli olabilir, ve spesifik işlem adımları farklı olacaktır.
