聚乙烯醇(PVOH)是一种水溶性聚合物,由于具有良好的黏结性、成膜强度和颜料分散性,在造纸工业中常用作胶黏剂和表面施胶剂。现今,PVOH成功地用在喷墨打印纸涂料中——从低档纸到高质量照相纸。喷墨打印介质需要一层油墨吸收层,必要时还需要一层表面涂层,两者对PVOH的性能要求也
Polyvinyl alcohol (PVOH) is a water-soluble polymer that is commonly used as an adhesive and surface sizing agent in the paper industry due to its good cohesiveness, film-forming strength and pigment dispersibility. Today, PVOH is used successfully in inkjet paper coatings - from low grade paper to high quality photographic paper. Inkjet print media require a layer of ink-absorbing layer, if necessary, also need a layer of surface coating, the performance of both PVOH requirements
