阳离子型聚丙烯酰胺的絮凝性能研究

Research on flocculating property of cationic polyacrylamide

以丙烯酰胺（AM）和二甲基二烯丙基氯化铵（DMDAAC）为原料，采用光引发聚合技术合成了阳离子型聚丙烯酰胺（CPAM），对CPAM的絮凝性能进行了研究。结果表明，CPAM的最佳药剂用量为2-4g／m^3，当阳离子度CD值为5％时，CPAM的絮凝效果最好；用PAM、PHP、CPAM处理望峰岗选煤厂的煤泥水，处理效果依次为CPAM〉PHP〉PAM。

Cationic polyacrylamide （CPAM） has been synthesized by photo-initiation method with co- hydrolysis of acrylamide （ AM ） and dimethyldiallylammonium chloride （ DMDAAC ）, and the flocculating property of CPAM has been researched. The experimental result showed that the optimum reagent dosage was 2 -4 g/m^3, the flocculating effect of CPAM was the best when cationic degree of CPAM was 5%. The processing effects were CPAM 〉 PHP 〉 PAM while tion plant. processing coal slurry of Wangfenggang coal preparation plant.
