| 摘 要： | 本研究了在几种条件的影响下，PMS对滑石粉悬浮体的絮凝努力学曲线的影响，发现对絮凝能力来说，各种条件都存在一个最佳区域，即PMS取代度为0．02－0．04，PMS加入量为25－40mg,pH值为大于5。另外从大分子形态和分散相表面电性质出发。对结果进行了讨论，认为PMS改性淀粉对滑石粉悬浮体的絮凝机理符合高分子絮凝剂“桥架”机理模型。

| Abstract: | s: The flocculation kinetics of PMS to talcum powe r was investigated. Fl occulation ability is maximum when the D.S of PMS is about 0.02~0.04, the concen tration of PMS in the system is about 25~40mg, the pH of PMS is greater than 5. These results were discussed in terms of configuration of polymer and surface p roperties of talcum powder conforms with the general direction of polymer flocul ant. |
