摘要
以丙烯酰胺、丙烯酰氧基乙基三甲基氯化铵、聚氧乙烯大单体和N ,N’ -亚甲基双丙烯酰胺为单体 ,进行四元反相微乳液共聚合 ,制备出新型含PEO支链的阳离子微粒絮凝剂。然后用该微粒絮凝剂分别对针叶木纸浆和特种纸白水进行了助留和絮凝性能的研究 ,结果表明 ,本新型微粒具有能单独使用、絮凝效果好和抗剪切性强等优点。
The novel cationic polyacrylamide microparticles with polyethylene oxide (PEO) side chains were synthesized via inverse microemulsion copolymerization of acrylamide (AM), PEO-macromonomer (PEO-A), acryloyloxyethyl trimethylammonium chloride (ADAMQUAT) and N,N'-methylenebisacrylamide (bis). The experiments on retention of paper-pulp and flocculation of waste water showed that the prepared novel microparticles can be used independently with excellent flocculation (retention)effect and good shear resistance.
