摘　　要：在自然界,钙基膨润土的资源量大,钠基膨润土的资源量小。前者物化性能和使用效果差,一般均须用人工钠化改型来提高其物化性能和使用效果。研究认为,钠化效果受膨润土自身质量、钠化改型剂、钠化改型剂添加量、钠化时间和钠化工艺等诸多因素影响。Natural Ca-bentonite resources are abundant, and Na-bentonite resources are small. Former has a narrow utilization with bad physical and chemistry properties. In order to get better use, sodiummodification was made to improve physical and chemistry properties of bentonite. The studing results showed soldium-modified bentonite was affected by bentonite quality, sodium-modification agent and its additive, sodium-modification time and its technology on Na-bentonite.
