摘要
以云南某地钙基膨润土为原料,将多种钠化剂进行改型,实验证明,钠化剂种类是人工钠化的关键,其中以NaF为改型剂钠化的膨润土性能最优。采用该钠化工艺,有三地的钠化膨润土的技术指标达到了JG/T193—2006《钠基膨润土防水毯》标准的要求。
With calcium-base bentonite as the raw material in certain areas of Yunnan Province,various sodium agents are modified.The experiment indicates varieties of Na-modified agent are the key of sodiumzation,and bentonite which contains Na-modified agent performance achieved optimization.The technical index of three types of Na-modified bentonite is up to the standard JG/T193-2006 waterproofing carpet of Na-base bentonite by means of the sodiumzation technology.
