Bentonite

الوصف

Bentonite deposits are normally exploited by quarrying. Extracted Bentonite is distinctly solid with the moisture content of approximately *0%. The material is initially crushed and if necessary activated wuth the addition of soda ash (Na2Co3). Bentonite is dried (air and/or forced drying) to reach a moisture content of approximately *5%. According to the final application, bentonite is either sieved (granular form) or milled (into powder and super fine powder form) or treated with acids to produce acid-activated bentonite (Blenching earths) or treated with organics to produce organoclys. The main constituent, which is the determinant factor in the clays properties, is the clay mineral montmorillonite.

Bentonite is the active protective layer of geosynthetic clay liners. Bentonite has multi-properties including swelling, hydration, water absorption, viscosity, thixotropic which makes it a multi application product for diverse industries.
