活性剂

Hydrophobically associating water-soluble polymer-based synthesis is difficult and not easily characterized, in part to hydrophobic chains connected to the water-soluble polymer, the general use of micellar copolymerization, or the use of the large surfactant monomer to copolymerization, polymer micelles need in the system by adding a large number of surface-active agent, which, after an increase of the complexity of the process.

疏水缔合型水溶性高分子很难合成，且不易表征，把疏水部分连接到水溶性聚合物链上，一般采用胶束共聚合或者使用具有表面活性的大单体进行共聚，胶束聚合需要在体系中加入大量的表面活性剂，这就增加了后处理过程的复杂性。

The result show, pH of solution, the type and concentration of surface-active agent all have marked effect, pH change can transform the disperse behavior of attapulgite particle by altering granularity distributing in different range, influencing double electromotive force between particle and solution.

研究表明，水溶液的pH值、表面活性剂的类型和浓度对凹土的分散稳定性皆有显著的影响，pH值的变化改变了不同粒径范围的粒子总量分布，改变粒子与溶液间双电层电动势，从而改变凹土粒子的分散行为：由于凹土作为带电粒子在极性溶剂中容易达到物理分散的目的，因此，凹土在极性溶剂中的分散状况大大优于在非极性溶剂中的分散。
