摘要
利用钠盐对钙基膨润土进行人工钠化,在活化剂的催化作用下,使钠改性膨润土具有较高的膨胀性能,当尿素添加量达15%时,改性膨润土的膨胀指数、膨胀倍和胶质价可分别达到26 ml/2g,91 ml/g和420 ml/15g,此时效果最佳。
The property of the calcium base bentonite was changed by using sodium salt,in catalytic action of activating agent,The changed bentonite shows higher expansibility,its expansion coefficient,times,colloidal valence can come to 26 ml/2g,91 ml/g and 420 ml/15g respectively.
