在湿法机械处理高岭土过程中,在细与极细颗粒的悬浮液中常出现一些对处理不利的情况.通过使用化学分散剂可以有效地改善高岭土的分散状态及流变性能。实验研究表明在水洗及旋流器分选中使用各种分散剂对分离效果及其性能参数有明显的改善.分散剂对沉降及过滤的负作用可用适当的方法消除.
In the wet mechanical treatment of kaolin, there are often some disadvantages in the treatment of fine and fine particles of suspension, which can effectively improve the dispersion and rheological properties of kaolin by using chemical dispersants. Experimental studies show that the use of various dispersants in water washing and cyclone separations significantly improves the separation performance and performance parameters, and the negative effects of dispersants on sedimentation and filtration can be eliminated by suitable methods.
