摘要

根据曼尼希反应对聚丙烯酰胺进行改性，合成了一种酰胺型聚合物阳离子絮凝剂。改性聚合物的使用使得高岭土水相分散体中聚合物对固相颗粒的吸附量增加，高岭土沉降率提高了1.2-1.4倍，并且与聚丙烯酰胺相比，可以扩大分散体不稳定的浓度范围。

Adsorption and flocculation properties of modified polyacrylamide in water dispersions of kaolin

A cationic flocculant with an amide-type polymer matrix was synthesized by modifying polyacrylamide according to the Mannich reaction. The use of a modified polymer leads to an increase in the adsorption of the polymer on solid phase particles in an aqueous dispersion of kaolin, an increase in the rate of kaolin sedimentation by a factor of 1.2–1.4, and makes it possible to expand the concentration range of dispersion destabilization compared to polyacrylamide.
