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.
