摘要
重点分析了蒙脱石的微观结构和吸水膨胀规律。蒙脱石吸水膨胀过程可分为两个阶段：第一阶段为快速膨胀期；第二阶段为缓慢膨胀期。快速膨胀期持续时间大约在0～1500min。通过对快速膨胀变形的适当控制，可开发出滞后膨胀式脱模养护剂。
The microstructures and swelling characteristics of absorbent sodium montmorillonite were discussed in this paper. The expanding processes were divided into two phases：first one named as quick swelling period, second one, slow swelling period. It took about 0- 1500 minutes to the montmorillonite in first period. A new lag inflating curing agent could be developed by controlling the expanding speed properly.
