聚乙烯醇是一种水溶性高聚物,性能介于塑料与橡胶之间,用途广泛。由于聚乙烯醇具有独特的强力粘接性、皮膜柔软、平滑性、耐油耐溶剂性、保护胶体性、气体阻绝性、耐磨耗性以及经特殊处理具有的耐水性,因此除了用于维纶纤维外,还大量用于生产涂料、胶粘剂、纤维浆料、纸品加工剂、乳化剂、分散剂等产品,应用范围遍及化纤、食品、医药、建筑、木材加工、造纸、印刷、农业、钢铁等行业。
Polyvinyl alcohol is a water-soluble polymer with properties ranging from plastic to rubber for a wide variety of uses. Because polyvinyl alcohol has unique strong adhesive properties, film softness, smoothness, oil and solvent resistance, protective colloidal properties, gas barrier properties, abrasion resistance, and water resistance by special treatment, it is not only used for vinylon fiber. In addition, it is also widely used in the production of paints, adhesives, fiber sizing, paper product processing agents, emulsifiers, dispersants and other products. Its applications cover chemical fiber, food, medicine, construction, wood processing, paper making, printing, agriculture, iron and steel, etc. industry.
