FILTRATION EFFECT OF NEW CATIONIC POLYMER ON FINE COAL

Not only the filtration mechanism of new style polymer named PQAAM (polyquaternary ammonium acrylamide graft copolymer)on the coal slurry is expounded,but also the influences of the specific viscosity and the cationic degree on the filtration cake moisture is studied in the paper.The experiment results show that the PQAAM has excellent filtration and dewatering effects on the fine coal.
