摘　　要：介绍了滑石粉特殊的表面性质-疏水性,及由此引起的润湿分散问题。文中采用三种润湿剂和三种分散剂对三种粒径的滑石粉进行分散实验,结果发现:非离子润湿剂1对滑石粉有较好的润湿效果,且其与分散剂六偏磷酸钠协同使用能有效地分散滑石粉。This research introduced the special surface property of talc (its hydrophobic surface) and the problems of wetting and dispersing caused by it. In this experiment three kinds of wetting agents and three kinds of dispersing agents were chosen to disperse three kinds of talc that were different in size. The results indicated that nonionic wetting agent 1 had a better effect on wetting talc, and it can effectively disperse talc together with sodium hexametaphosphate.
