直流电场作用下黏土矿物新生矿物试验研究

Experimental Studies on New Minerals From Clay Mineral Under DC Electric Field

摘要: 针对蒙脱石黏土矿物具有遇水软化、泥化和强膨胀等性质，以蒙脱石黏土矿物作为研究对象，在电位梯度为0.25 V·cm^-1和0.5 V·cm^-1及CaCl₂电解液浓度为1 mol·L^-1条件下进行改性，并对改性后蒙脱石黏土矿物的含量及新生矿物进行了试验研究。电场作用后，蒙脱石的含量降低，生成三水铝石、方解石、硬石膏等新矿物。

Abstract: The properties of montmorillonitic clay mineral are water-expanding, argillization and strong dilation. Under 0.25 V·cm^-1 and 0.5 V·cm^-1 electric gradient and 1 mol·L^-1CaCl₂ electrolyte concentration, montmorillonitic clay mineral is modified. The mineral content and new minerals are studied after modified. The content of montmorillonitic is reduced, and the new minerals are gibbsite, calcite, and anhydrite.
