Etapa de detectare
Specific testing steps of polymer cement waterproof coating:
Bond strength: The paint sample is coated on the appropriate substrate, and after it is dried, the tensile test is carried out using a tensile testing machine to obtain the bond strength parameters of the sample.
Rezistenta la apa: SOAK the coating sample in water and observe the changes, such as peeling, foaming and other phenomena indicate poor water resistance.
Alkali resistance: Use the alkalinity meter to measure the coating sample, and get its alkali resistance in alkaline environment.

Durabilitate: Put the coating sample into the Pirelli testing machine, conduct the simulated performance aging test, observe the performance change, to evaluate its durability.
Impermeabilitate: Use a hydraulic tester to test the permeability of the coated sample to evaluate its impermeability.
Rezistenta la intemperii: Put the coating sample in a constant temperature and humidity box to conduct a simulated performance aging test, observe its performance changes, to evaluate its weather resistance.
Performanța construcției: A rheometer is used to test the coating sample and obtain its rheological performance parameters, such as viscosity and shear modulus, to evaluate its construction performance.
