| 摘 要： | 以湖北鄂州低品位钙基膨润土为试验研究对象,采用湿法提纯工艺,选用0.5%六偏磷酸钠为分散剂,矿浆浓度25.0%,将膨润土纯度从75.43%提高到89.91%。对提纯后的膨润土进行钠化改型试验,确定了影响钠化的主要因素和钠化最佳工艺条件,制备的钠基膨润土d（001）为1.237 0nm,膨胀容和胶质价分别为72mL/g及500mL/15g,为优质的钠基膨润土。

| Abstract: | A Ca-bentonite from Ezhou is taken as the object of the study.The wet processing technology of purification is carried out to enhance the grade from 75.43% up to reach 89.91% under the condition of using sodium hexametaphosphate 0.5% as dispersant and a slurry density of 25%.The optimum conditions and best industry conditions of Na-activation are confirmed by test.A high quality Na-bentonite is obtained with the d（001） value is 1.237 0nm,expansion multiple is 72mL/g and colloid index is 500mL/15g. |
