酸、热处理对高岭土水行为的影响

表面水和结构水是高岭土中水的两种主要存在形式,它们的行为在很大程度上反映了高岭土的结构和表面状态。本文主要研究高岭土的酸、热处理对其水行为的影响,利用热分析方法测定了不同酸、热处理条件下高岭土的吸水和脱水过程,比较各种处理条件对表面水和结构水的影响。

The Influences of Acid and Heat Treatments on the Water Behavior of Kaolin

Water at the surface and constitutional water are two principal forms of water presence in kaolin. Their behaviors reflect to a good extent the constitution and surface state of kaolin. This paper deals mainly with the in- fluences of acid and heat treatment on the water behavior of kaolin. The processes of water absorption and dewater of kaolin under different acid and heat treatment conditions are determined by making use of thermal analysis. The influences of various treatment conditions on the water at the surface and constitutional water are compared.
