| 摘 要： | 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2~4 g/m3,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。

| Abstract: | Cationic polyacrylamide(CPAM) has been synthesized by photo-initiation method with cohydrolysis 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 processing coal slurry of Wangfenggang coal preparation plant. |
