非水解的聚丙烯酰胺是一种完全絮凝剂,这已被现场实践和室内实验所证实.但不同水解度的水解聚丙烯酰胺,其絮凝作用存在明显差异.一般来说,水解度30%左右的水解聚丙烯酰胺(代号HPAM),选择性絮凝作用较强.《地质与勘探》1981年第5期“造浆试验方法探讨”一文认为“在条件相同情况下(如都配成浓度6%的泥浆),加碱处理,黑山膨润土泥浆需600～1000ppm水解度为30%左右的水解聚丙烯酰胺,才能使它完全絮凝成清水,而对高岭土或伊利石粘土 Non-hydrolyzed polyacrylamide is a complete flocculant, which has been field practice and laboratory experiments confirmed, but different degrees of hydrolysis of hydrolyzed polyacrylamide flocculation there are significant differences in general, the degree of hydrolysis of about 30% Of the hydrolysis of polyacrylamide (codenamed HPAM), selective flocculation stronger.Geological and Exploration 1981, No. 5 “pulp test method of discussion,” a paper that "under the same conditions (such as the concentration of 6% Of the mud), alkali treatment, Montenegro bentonite slurry to be 600 ~ 1000ppm degree of hydrolysis of about 30% hydrolyzed polyacrylamide, it can be completely flocculated into water, and kaolin or illite clay
