Product Introduction
Bentonite is a kind of water bearing clay ore mainly composed of montmorillonite, because of its special properties.Such as : swelling, cohesiveness, adsorption, catalysis, thixotropy, suspension, cation exchange, etc.
Sodium bentonite is the one with alkalinity coefficient greater than or equal to 1.
Characteristics of well drilling bentonite:
Good suspension and thixotropism property.
Lower filter loss and good making motar property.
Easy making, easy adjust specific gravity of drilling fluid, etc.
