The special characteristics that Bentonite possesses make it extremely viable and useful. The properties of bentonite are absorption, expansion, viscosity, thixotropy, colloidal, waterproofing and binding. Bentonite absorbs water forming a semisolid gel like substance due to the presence of strong hydrostatic pressure resistance. It is used as an additive, making the substance durable and heat resistant. Owing to these properties, Bentonite finds applications in sealing and lining ponds, docks, landfills etc. Viscosity of Bentonite is inversely proportional to the force applied. Sodium bentonite allows penetration of water and swells up. On the other hand, Calcium bentonite with strong positive charge does not allow water to penetrate through its platelets.
There are mainly two types of bentonite i.e. Calcium Bentonite and Sodium Bentonite. They are used in following industries which are as follows: Oil Drilling Bentonite, Foundry Bentonite, Animal Feed Bentonite, Paper Bentonite, Civil Engineering Bentonite, Construction Bentonite, Pilling Bentonite, Geosynthetic Clay Liner Bentonite, Agriculture Bentonite, Horizontal Direction Drilling Bentonite, Iron Ore Pelletizing Bentonite, Water Well Drilling Bentonite, Cat Litter Bentonite, Earthing Bentonite, Water Treatment Bentonite, Pond Sealing Bentonite and Cosmetic Bentonite.
