本文选择了几种粘土进行颗粒分散分离方法的比较。实验结果证明,研磨分散法很适宜于粘土颗粒的分离,以云泰为主的黄土,研磨十次分离较完全;以濛脱为主的常家沟膨润土除采用研磨处理外要加上化学处理,内蒙膨润土是钠质粘土,十次研磨处理很好;以高岭石为主的阳西瓷土以碳酸钠的分离法较为适合。各级颗粒分别用阳离子交换量、差热分析、X 射线分析来研究粘土矿物的组成,结果表明膨润土及黄土颗粒愈细,濛脱石及云泰含量愈增。
In this paper, several kinds of clays were selected for the method of particle dispersion separation. The experimental results show that the grinding dispersion method is very suitable for the separation of clay particles, Yun Tai-based loess, ten times more complete separation of grinding; montmorillonite-based Changjiagou bentonite in addition to the use of grinding treatment plus chemical treatment , Inner Mongolia bentonite is sodium clay, ten times of grinding treatment is good; kaolinite-based Yang Xizang clay with sodium carbonate separation method is more suitable. The results showed that the finer the bentonite and loess particles, the more the contents of montmorillonite and yuntai increased.
