Open publisher page 1 citations

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 CPAMPHPPAM while processing coal slurry of Wangfenggang coal preparation plant.
