Physical Modification of Bentonite on the Salt Resistence Capacitiy
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.
