发明名称 Composition and method for improving retention and drainage in papermaking processes by activating microparticles with a promoter-flocculant system
摘要 A composition and method for improving retention and drainage in a papermaking process is disclosed. An unexpected synergistic effect has been observed when certain amounts of a promoter are used in conjunction with a microparticle. Optionally, a flocculent is also used to further improve the observed synergism. The microparticle includes an inorganic anionic or cationic siliceous material. The promoter includes a modified diallyl-N,N-disubstituted ammonium halide polymer. The flocculant includes one or more high molecular weight, water-soluble cationic, anionic, nonionic, zwitterionic, or amphoteric polymers.
