对膨润土中蒙脱石进行类质同象置换研究,首先需对样品进行提纯和钠化处理。本文结合泥浆工艺原理,选用碳酸钠为分散剂,分析并控制分离条件,优选钠化的化学条件,采用简易化学检测方法了解钠化进程,从10件样品的试验结果表明效果良好。 To study the isomorphous displacement of montmorillonite in bentonite, the sample needs to be purified and sodium treated first. Based on the principle of slurry technology, sodium carbonate was chosen as dispersant. The separation conditions were analyzed and controlled. The chemical conditions of sodiumification were optimized. The simple chemical detection method was used to understand the sodiumification process. The results of 10 samples showed good results.
