| 摘 要： | 根据信阳膨润土的特性,采用湿法对其进行提纯。分别考察了六偏磷酸钠用量、液固比、沉降时间、搅拌时间对提纯效果的影响,并用吸蓝(MB)法和X-射线衍射对提纯效果进行检验。结果表明,信阳膨润土最佳提纯条件:分散剂用量0.125%、最佳液固比12、搅拌时间80min、沉降时间120min。膨润土的蒙脱石含量从61%提高到90%以上。

| Abstract: | According to the characteristics of bentonite from Xinyang,the method of wet-way was used for purification.The experiment tested the effects of sodium hexametahposphate,liquid-solid ratio of bentonite slurry,stirring time,and sedimentation time on the purification of bentonite,respectively.The effect of purification was tested by the methods of blue adsorbed and X-ray diffraction photographs.The results showed that the best conditions for purification was when the concentration of dispersant was 0.125%,liqu... |
