粘土的层间交联和多孔材料的形成条件

本文利用ＸＲＤ、ＩＲ等方法研究２：１型的蒙脱石粘土矿物和聚合羟基铝交联剂的层间交联作用，并对多孔粘土材料 的形成条件及过程作初步探讨。

Interlayered Cross-linking and Formation Conditions of Porous Clay

The interlayered cross-linking of a 2:1 type montmorillonites with a hydroxy-polymers Al wasstudied by means of XRD and IR. The formation conditions and preparation process of porousclay were also dealt with. The results show that the preparation conditions such as concentrationsof cross-linking agent, reaction temperatures and washing greatly effect the formation of porousclay. The dilute solution of cross-linking agent is beneficial to the formation of porous clay; andthe process of cross-linking is reversible.
