摘　　要：以浙江某地绿脱石型钙基膨润土为原料,采用传统的钠化方法对该膨润土进行改性。试验采用传统干法中的轮辗钠化法,Na2CO3为钠化剂。以钠化剂的用量、用水量、混碾时间及陈化时间为四个因素,进行正交试验,并得到了最优工艺。试验结果表明,绿脱石型钙基膨润土可以用传统钠化方法改性。The nontronite bentonite from Zhejiang province was used as raw material,and modified by the traditional dry method of wheel rolling with Na2CO3 as modifier.Orthogonal test was carried out,and the four factors are the dosage of Na2CO3,the dosage of water,mixing time and aging time.The optimum process was obtained by the range analysis.The results show that the nontronite Ca-bentonite can be effectively modified by the traditional sodium modification method.
