Description

Product introduction

Montmorillonite is 2:1 silicate minerals containing crystal water's, which comprise two layer total of top connected silicon-oxygen tetrahedron clipping a layer of edges connected aluminum (magnesium) oxygen (OH) octahedral sheet. Al3+ in octahedral of pillars structure was replaced by Mg3+, Fe3+, Fe2+, etc., that results in octahedral distortion and then force the tetrahedral sheet to make rotation, elongation, contorted and other forms to adjust, until the bonds is broken, the polyhedron core cation is exposed, and different strength permanent negative charge between the layers is appeared. Accordingly negatively charged adsorption characteristics come into being.
