PVA sponge bibulous roller, also called PVA sponge bibulous roller, PVA sponge, its purpose is bibulous roll bibulous, bibulous ability
Can reach its own weight 6 ~ 10 times. It consists of hydrophilic polymer resin (PVA) and chemical foaming agent, mixed heat preservation to shape.
Characteristics: the continuous porosity, there were OH the foam molecules, hydrophilic can best, can quickly absorb board face water stains, softness, elastic, won't scratch the surface. Bibulous optimal, temperature 60 ℃, before using immerse first water for 30 minutes, let the fluid balance into the sponge in the roll (moisturizing). Suitable for: circuit board inside and outside layer, BGA, IC feet frame, LCD monitor, wipe fiber cloth, semiconductor wafer cleaning brush, glass, food, rolled steel industry, swimming pool, tennis court, etc... is now clean the most economic, water imbibition excellent the roller.
