Suction roll: also known as sea swab - use PVA foam sponge made of high density hydrophilic molecule, which communicate with each other between microporous, water absorption good, fast drying, good corrosion resistance, use it to suction surface of the water is ideal. Widely used in glass, steel, aluminum and other industries whose products panel cleaning, pressure fluid, water, dehydration step. Full fast dry them drop the product surface. Material is generally PVA (polyvinyl alcohol) foam sponge; specifications inner diameter (ф5-ф100) outer diameter (ф200 within) (L10-L2000), etc., can be customized according to different sizes. Sponge roller technology MEASURES: ① water absorption capacity of up to own the dry weight of 6 to 10 times. ② general temperature should not exceed 60 ℃, otherwise it will be aging and shorten lifespan, good adhesion suction roll, such as temporary do not, it should be on the water conservation, preservation. ③ normal use for a period of three months. Hydrophilic polymer PVA (polyvinyl alcohol) sponge roller is made, is a continuous pore foam, there 0h group, hydrophilic excellent performance in the molecule, can quickly dry the plate surface water, good flexibility, not They can scratch the surface, and can be widely applied to the printed circuit board. Glass, stainless steel and other panel cleaning, water, fluid pressure, dehydration and other processes. Specifications: 1, the water absorption capacity can reach 8-10 times its own weight 2, the normal life 3-6 months technical parameters: 1, temperature does not exceed 60 degrees, otherwise it will shorten the life of aging and 2, acid and alkali 3, when not in water conservation, in order to avoid shrinkage deformation.
