摘要
以钙基膨润土为原料 ,系统地研究了改型剂种类与用量、矿浆浓度以及搅拌时间对改型效果的影响。结果表明 :以碳酸钠为改型剂 ,用量为 4% ,矿浆浓度 15 % ,搅拌时间为 15min ,对膨润土进行钠化改型 。
The main technical conditions for modifying of Ca-bentonite with sodium carbonate or sodium compounds were determined. The natural Ca-bentonite was transferred successfully into artificial Na-bentonite by which the chemical and physical properties of Ca-bentonite was improved largely. Moreover, the factors affecting the quality of modifying of Ca-bentonite were also discussed.
