Product Description
Bentonite is a non-metallic mineral with montmorillonite as its main mineral composition. Montmorillonite structure is composed of two silica tetrahedrons sandwiched by a layer of aluminum oxide octahedron2: Type 1 crystal structure, because there are some cations in the layered structure formed by montmorillonite cells, such as Cu, Mg, Na, K, etc., and the interaction of these cations with Montmorillonite cells is very unstable, easy to be exchanged by other cations, so it has good ion exchange.
Bentonite is also called bentonite, bentonite or bentonite. China has a long history of developing and using bentonite, which was originally only used as a detergent. (The Renshou area of Sichuan Province has had open-pit mines for hundreds of years, and locals call bentonite soil powder.) It's only been in widespread use for a hundred years or so. The United States was first found in the ancient formation of Wyoming, yellow-green clay, after adding water can expand into a paste, and later people put all the clay with this property, collectively referred to as bentonite. In fact, the main mineral composition of bentonite is montmorillonite, the content is 85-90%, and some properties of bentonite are also determined by montmorillonite. Montmorillonite can be in a variety of colors such as yellow green, yellow white, gray, white and so on. Can be a dense block, can also be loose soil, with fingers rubbing slippery, small pieces of water after the volume expansion several times to 20-30 times, in the water is suspended, when the water is mushy. The properties of montmorillonite are related to its chemical composition and internal structure.

Application
Montmorillonite has adsorbability and cation exchange properties, and can be used to remove toxins from cooking oil, purify gasoline and kerosene, and treat wastewater. Because of its good water absorption and expansion performance as well as dispersion and suspension and pulping properties, it is used for drilling mud, flame retardant (suspension fire extinguishing); It can also be used as filler in the paper industry, which can optimize the properties of coatings such as adhesion, hiding power, water resistance, wash resistance, etc. Because of its good adhesion, it can replace starch for yarn sizing in the textile industry, which saves grain and does not raise hair, and does not emit odor after paddling. Bentonite (montmorillonite) has good physical and chemical properties. It can be used as purification decolorizing agent, binder, thixotropic agent, suspension agent, tabilizer, filler, feed, catalyst, etc., widely used in agriculture, light industry and cosmetics, pharmaceuticals and other fields, so montmorillonite is a widely used natural mineral material.
