The advantages of bentonite are mainly reflected in the following aspects: First, bentonite has excellent water absorption and expansion and cation exchange, and can effectively adsorb and separate solid and liquid particles. Secondly, bentonite also shows good viscosity, thixotropy and lubricity, and is widely used in seepage prevention, sealing and other fields. In addition, bentonite has the ability to adsorb a variety of substances and can be used to purify the environment and treat industrial wastewater. At the same time, bentonite also has certain catalytic, chemical stability and electrical conductivity, which provides strong support for many industrial fields.
