Bentonite

Bentonite is by the two silicon-oxygen tetrahedron intervening layer of aluminum oxygen octahedron composed of layered clay mineral. Product Nature: Bentonite is a main component of montmorillonite, according to the content of montmorillonite exchangeable cation type, concentration and crystallization of the different nature of the chemical, into sodium, calcium, and magnesium-based, Al (OH) - such as bentonite. Uses: Bentonite areas of application is very extensive. Since 1920 the United States has begun to replace the general application of bentonite clay, used for foundry sand binder, its field of application in machine-building, metallurgy, drilling, oil, chemicals, food, environmental protection and other industries to expand. A low-viscosity, sodium-activated bentonite imparting excellent green compression and hot compression strengths to molding sand where high temperature metal pouring occurs. A selectively mined, natural calcium bentonite exhibiting excellent mechanical properties and flowability and provides easy shakeout. In addition, the Bentonite is a detergent specialties. According to incomplete statistics, China currently bentonite products with an annual output of about 2.7 million sales tons, Casting for which 100 110 million tons of sand and drilling mud for 700,000 tons of metallurgical pellet 450,000 tons, Oil for bleaching (activated clay) 200,000 tons for the other 20-30 million tons. The website of bentonite products and the production of special equipment activated clay, has been adopted by both the end-user certification, first-class quality products, and authorized sales agents of the firm.
