| Abstract: | The article researched a microparticle retention and drainage system which was composed of CPAM and a graft compolymer.The latter was made of bentonite and AM with ammon persulfate and sodmum sulfite as reaction initiatior in the alkaline environment.e application results showed that when pH was 4~7,amount of the graft compolymer was 0.15%~0.20% in pulp,amount of CPAM was 0.035%~0.04%,the microparticle retention and drainage system had a good e?ects of retention and drainage. |
