| 摘 要： | 聚丙烯酰胺(PAM)是一种新型高效的助留助滤剂,是一种易溶于水、几乎不溶于有机溶剂的有机高分子化合物。聚丙烯酰胺主链上有活泼的酰胺基和双键,通过采用不同的合成方法引入不同的官能团,可以得到不同分子量和不同电荷密度的聚丙烯酰胺产品。本文对阳离子聚丙烯酰胺、阴离子聚丙烯酰胺、两性聚丙烯酰胺及非离子聚丙烯酰胺这四大种类聚丙烯酰胺的特征、与纤维素表面及悬浮物之间相互作用机理及受外界条件影响分别进行了简要综述,展望了聚丙烯酰胺类助留助滤剂的发展方向与应用前景。

| Abstract: | Polyacrylamide(PAM) is a kind of new,high efficient retention aid,which is soluble in water,almost insoluble in organic solvents.PAM lord chain has lively amide and double bond,by the use of different synthesis methods into different functional group,can get different molecular weight and different charge density of polyacrylamide products.In this paper,the cationic PAM,anionic PAM,amphoteric PAM,and the nonionic PAM four kinds of polyacrylamide characteristics,and external condition influence mechanism which affects interaction between cellulose surface and suspended matter were reviewed,look ahead the direction of development and application prospects of polyacrylamide retention aid and drainage aid. |
