What is pva polyvinyl alcohol?
Function
1.In the textile industry , they are mainly used as yarn pulp, fabric finishing agents, and raw materials of vinylon fibers;
2. In the construction and decoration industries, they can be used as mortar cement additives, paint additives for interior and exterior walls, and molding plate adhesives;
3. In the chemical industry, they can be used as polymerization emulsifiers, dispersants, and raw materials for the production of PVF and butyral resins;
4. In lumbering and paper-making industries, they can be used as adhesives;
5. In petroleum exploitation, they can be used as well-cementing agents
Application
PVA is a widely used water-soluble polymer that can quickly dissolve in water to form a stable colloid. Its performance is between that of plastic and rubber. In addition to being used as a fiber raw material, it is also widely used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products. Its application range covers textiles, food, medicine, construction, wood processing, papermaking, printing, agriculture, steel, etc Polymer chemical industry and other industries.
