Key properties and testing methods of polyurethane waterproof coatings
Polyurethane waterproof coating is a kind of polyurethane resin as the main component, adding a variety of fillers, diluents and other substances made of waterproof coating, has excellent weather resistance, odporność na zużycie, corrosion resistance and chemical resistance. 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.

Key properties and testing methods of polyurethane waterproof coatings
Procedura metody detekcji
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, i zapisz wyniki testu.
Odporność na warunki atmosferyczne: Sprawdź odporność powłoki na warunki atmosferyczne za pomocą komory starzenia lampy ksenonowej lub komory promieniowania spektralnego, i zapisz wyniki testu.
Wodoodporność: Use water penetration test equipment and soaking test equipment to test the water resistance of the coating, i zapisz wyniki testu.
Siła wiązania: 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.
Odporność na zużycie: Wear testing machine is used to test the wear resistance of the coating, and the test results are recorded.
Kolor i połysk: Wykonaj test za pomocą miernika różnicy kolorów i miernika połysku przy standardowym źródle światła i zapisz wyniki testu.
For some special coatings, it may be necessary to use other instruments and equipment for testing, and the specific operation steps will be different.
