粘土的层间交联和多孔材料的形成条件

Interlayered Cross-linking and Formation Conditions of Porous Clay

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．结果表明，交联剂浓度、交联温度和洗涤方式等制备条件对多孔粘土材料的形成有较大的影响，稀浓度的交联剂溶液对材料的形成较为有利，交联过程是双向可逆的．

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.
