Proprietà chiave e metodi di prova dei rivestimenti impermeabili poliuretanici
Il rivestimento impermeabile in poliuretano è una sorta di resina poliuretanica come componente principale, aggiungendo una varietà di riempitivi, diluents and other substances made of waterproof coating, has excellent weather resistance, resistenza all'usura, resistenza alla corrosione e resistenza chimica. Polyurethane waterproof coating is widely used in building roof, basement, ground, pool, storage tank and other waterproof engineering and railway, highway, bridge, tunnel and other transportation infrastructure waterproof and anti-corrosion field.

Procedure of detection method
The following is the performance of polyurethane waterproof coating to be tested and its testing steps:
Prestazioni costruttive: 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.
Resistenza all'acqua: Use water penetration test equipment and soaking test equipment to test the water resistance of the coating, and record the test results.
Forza del legame: The coating adhesion to the substrate was tested using the delimiting tester and the stripping tester, and the test results were recorded.
Resistenza all'impatto: The impact testing machine is used to test the impact resistance of the coating, and the test results are recorded.
Resistenza all'usura: 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.
For some special coatings, it may be necessary to use other instruments and equipment for testing, and the specific operation steps will be different.
