Product introduction
聚乙烯亚胺是通过乙烯亚胺的聚合作用产生的一种水溶性聚合物。 它不是完全的线性聚合物,而是一种包含伯胺,仲胺和叔胺的部分支链聚合物。 聚乙烯亚胺与其他低分子量的胺类具有多种化学反应性一样,可以进行多种化学改性。 特性 ●现存材料中最高的阳离子密度。 ●非常高的活性。 ●水溶性能力。 1、高附着性和吸附性 氨基能与羧基反应生成氢健。 氨基能与羧基反应生成离子健。 氨基能与碳酰基反应生成共价健。 聚乙烯亚胺由于具有极性基团(氨基)和疏水基(乙烯基)结构,能够与不同的物质相结合。利用这些综合结合力,可广泛应用于接着,油墨,涂料,粘结剂等领域。 2、高阳离子性 聚乙烯亚胺在水中以聚合阳离子存在,可以中和和吸附所有阴离子物质,还能螯化重金属离子。利用其高度的阳离子性,可以应用于造纸水处理,电镀液,分散剂领域。 3、反应性 聚乙烯亚胺由于具有反应性很强的伯胺和仲胺,能够很容易与环氧,酸,异氰酸酯化合物和酸性气体反应。利用此特性可作为环氧树脂反应剂,醛吸附剂和染料固定剂使用。 应用 洗涤剂、粘合剂、水处理、油墨、染料、化妆品和造纸业、助粘剂、层压底漆、固色剂、絮凝剂、阳离子分散剂、稳定增强剂、表面活性剂、螯合剂以及醛类和氧化物清除剂。 蛋白质沉淀剂。
