Physical Modification of Bentonite on the Salt Resistence Capacitiy

Abstract:

A kind of bentonite composite with high salt resistance capacity was prepared using physical modification including physical mineral separation and doping porous non-metallic minerals. The results showed that through physical mineral separation, the content of montmorillonite and the salt resistance capacity increased substantially. The bentonite compsite sample doped by 5.0% diatomite showed better salt resistance capacity than the other compsite samples. The salt resistance mechanism was discussed through the double layer theory and physical and chemical properties of doped minerals.
