China Factory Of PVA/ Polyvinyl Alcohol
Excellent adhesive cellulose powder PVA to be chemical auxiliary agent
Polyvinyl alcohol (PVA)is an excellent water-based adhesive.The general product is flake,granular or flocculent.It is not easily soluble in cold water.Heating is generally required during dissolution.After being finely pulverized and surface treated,it has better cold water dissolving performance.But because of its thermoplasticity,pulverization becomes particularly difficult.Our factory adopts a special liquid nitrogen low temperature cooling process to ensure that the powder of the crushed material is uniform.So that the material has excellent water solubility.
Application
Mortar,putty powder,coating,interface agent,decorative plaster,tile jointing agent,silicon nitride and other industrial ceramic
powder bonding,cement,gypsum additives,etc.
