摘要

本文通过用全同和无规立构的聚(N-丙基-2-乙烯基吡啶溴化物)QIP2VP和QAP2VP为絮凝剂

对高岭土悬浮液进行絮凝实验

研究了絮凝剂分子结构对絮凝效果的影响

得到以下结果:(1)QAP2VP的絮凝能力优于QIP2VP.(2)QAP2VP的絮凝效果随分子量增大而提高

而QIP2VP无此规律.(3)絮凝剂的季铵度很低时

絮凝效果提高.(4)在某絮凝剂浓度出现一个反常絮凝现象

作者认为这是”同电荷稳定“现象.(5)从实验数据得出各实验参数间的关系式.

Abstract

Isotactic-and atactic-poly (N-propyl-2-vinylpyridinium bromide) QIP2VP and QAP2VP were used as flocculants for kaolin suspension. The effects of their molecular structures on flocculation were studied. The results are as follows: ( 1 ) The ability of flocculation of QAP2VP is better than that of QIP2VP. ( 2 )QAP2VP but not QIP2VP

Showed that the ability increased with increased molecular weight ( 3 )A low degree of quaternization is effective for the flocculation. ( 4 ) An abnormal phenomenon

which is considered as "Homocha-rge stabilization"

was discovered at a certain concentration of flocculants ( 5 ) An equation between the experimental parameters was derived.
