Proprietățile cheie și metodele de testare ale acoperirilor impermeabile din poliuretan
Acoperirea impermeabilă din poliuretan este un fel de rășină poliuretanică ca componentă principală, adăugând o varietate de umpluturi, diluents and other substances made of waterproof coating, has excellent weather resistance, wear resistance, corrosion resistance and chemical resistance. Polyurethane waterproof coating is widely used in building roof, subsol, 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:
Performanța construcției: 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.
Rezistenta la apa: 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.
Rezistenta la uzura: 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.
Pentru unele acoperiri speciale, poate fi necesară utilizarea altor instrumente și echipamente pentru testare, iar pașii specifici de operare vor fi diferiți.
