Buod ng key pagganap ng JS waterproof coating at ang kanyang mga instrumento sa pagsubok
JS hindi tinatagusan ng tubig patong ay isang uri ng polimer emulsyon, inorganic pigments, mga filler, additives at iba pang mga pangunahing hilaw na materyales, after mixing, grinding, dispersion and other processes made of a waterproof coating. It has a wide range of applications, can be used in building roof, basement, tunnel, pool and other projects in the waterproof coating, with good waterproof performance, mahabang buhay ng serbisyo, convenient construction and other advantages.

Hakbang ng pagtuklas
Film thickness detection: select the area of flat coating surface, use a thickness meter to measure, measure multiple points and take the average value.
Pagdikit 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, cracks, 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.
