【摘要】 国外阳离子型聚丙烯酰胺的产量占聚丙烯酰胺产品的50％以上,该产品是水处理及造纸行业中用途最广泛的高分子聚合物之一。反相乳液聚合法合成阳离子型聚丙烯酰胺是国外80年代末期的先进技术,而国内一直没有相关报道。1996年(原)化工部广州聚丙烯酰胺工种技术中心承担了国家石油和化学工业局的“九五”国家重点科技攻关项目“微生物法丙烯酰胺聚合新品种的开发研究”,并已经于2000年通过鉴定验收。该项目已经建立300t/a的中试装置,生产工艺路线合理、能耗较低、产品性能稳定,具有速溶特性,在国内外市场有一定的竞争力。更多还原

【Abstract】 Cationic - type polyacrylamide is one of the polymers which have the widest uses in water treatment and paper making industries, whose capacity is over 50% of polyacrylamide products abroad. The synthesis of cationic - type polyacrylamide via reversed emulsion polymerization method is an advanced technology at the late 80’s abroad, and there have not been related reports in China. In 1996 Guangzhou Polyacrylamide Engineering and Technical Center of the former Ministry of Chemical Industry undertook national important science and technology breakthrough project " R&D on Novel Acrylamide Polymers via Microbial Method" , which has passed appraisal in 2000. This project resulted in the construction of a 300t/a pilot plant characterized by reasonable synthesis route, low energy cost, stable product properties and quick dissolving, which is relatively competitive in China and abroad.更多还原
