Sponge suction roller application introduction_faq

The sponge suction roller made of hydrophilic polymer PVA (polyvinyl alcohol) is a continuous pore foaming, with 0h group in the molecule, and has excellent hydrophilic performance. It can quickly absorb water on the surface of the board, and has good elasticity. It can scratch the surface of objects and can be widely used in printed circuit boards. In the process of cleaning, absorbing water, pressing liquid, and dehydrating glass products, stainless steel plates and other panels. Technical indicators: 1. The water absorption capacity can reach 8-10 times of its own weight. 2. The normal service life is 3-6 months. Technical parameters: 1. The use temperature does not exceed 60 degrees, otherwise it will age and shorten the service life. 2. Acid and alkali resistance 3. Maintain in clean water when not in use to avoid shrinkage and deformation
