Langkah deteksi
Film thickness detection: select the area of flat coating surface, use a thickness meter to measure, measure multiple points and take the average value.
Adhesion test: according to the standard operation, the adhesion detector is clamped on the coating surface, and the force is gradually applied until the coating peeling and peeling occur.
Impermeability test: the coating sample is placed in the impermeability tester, and the permeability test is carried out under pressure to observe whether the permeability phenomenon occurs.
Tensile strength test: Select the area with flat coating surface, make standard sample, use tensile testing machine for tensile test, record the maximum tensile strength value.

Weather resistance test: the coating sample is placed in the weather resistance test box, and the environmental simulation test such as light, heating and water mist is carried out for a certain period of time to observe whether the coating falls off, cracks and fades.
Durability test: the coating sample is placed in the artificial climate aging box, and the environmental simulation test such as heating, ultraviolet irradiation and humid heat cycle is carried out for a certain period of time to observe whether the coating falls off, retak, fading and other phenomena.
Storage stability test: For the paint stored for a certain period of time, use visual inspection to observe whether there are changes in its appearance, stratification and other phenomena.
