Bentonite property

Bentonite features with high hygroscopicity which can adsorb the water for 8 to 20 times of their own volume to expansion to 30 times. In aqueous media, the bentonite can disperse colloidal suspension and features with definite stickiness, thixotropy and lubricity. The bentonite also has plasticity and cohesiveness and the things such as silt mixture also have these features. It also features with high cation exchange capacity and adsorptive capacity.
