Bentonite powder

Key Attributes.

Sodium bentonite powder absorbs liquid, has tremendous swelling ability, is often used in manufacturing and has many allied applications. Because of its excellent stickiness and fireproof-ability, bentonite is often used as a bond and regulator in molding ferrous and nonferrous metals and oil and fat refining. Its bonding capabilities make it suitable for metal casting and, when mixed with clay and sand, it forms an adhesive used in building and sewage reservoirs. One of the foremost uses of bentonite powder occurs in the oil drilling and mining industries. The extraction of cuttings is a vital part of the oil drilling process. When bentonite is mixed with water or foam it forms a slurry, which is forced down to the drill bit. The slurry aids in raising the cuttings to the surface and aids in achieving a cost-cutting drilling process. When drilled holes must be filled, bentonite pellets are poured down the hole and water is added. Because the pellets are solid, they float. The pellets swell together and set in place sealing the hole. Bentonite is an effective water sealing agent used in ditches, ponds and lagoons. It is also used in constructing landfills, wastewater holding facilities when indigenous clay is unavailable and for reconstructing failed landfill.
