Bentonite (original soil, soil powder)

Bentonite (original soil, soil powder)

Bentonite is a non-metallic mineral with montmorillonite as its main mineral component. The structure of montmorillonite is a 2:1 crystal structure consisting of two silica tetrahedrons and a layer of alumina-oxygen octahedron. Because there are some cations in the layered structure formed by montmorillonite cell, such as copper, magnesium, Na, K, and so on, and the interaction between these cations and montmorillonite cell is very weak and is easily exchanged by other cations. It has good ion exchange property. Overseas, it has been applied in more than 100 departments in 24 fields of industrial and agricultural production, with more than 300 products. Therefore, it is called "omnipotent soil".

Bentonite is also called porphyry, bentonite or bentonite. China has a long history of developing and using bentonite, which was originally only used as a detergent. (There were opencast mines in Renshou area of Sichuan hundreds of years ago. Locals call bentonite as earth powder). Really widely used but only a hundred years old. The earliest discovery in the United States was in the paleostrata of Wyoming, where yellowish-green clay can expand into paste after adding water. Later, people called all clays of this nature bentonite. In fact, the main mineral composition of bentonite is montmorillonite, the content is 85-90%. Some properties of bentonite are also determined by montmorillonite. Montmorillonite can be in various colors such as yellow-green, yellow-white, gray, white and so on. It can be compact or loose soil. It has slippery feeling when rubbed with fingers. The volume of small pieces swells several times to 20-30 times after adding water. It is suspended in water and pasty when water is low. The properties of montmorillonite are related to its chemical composition and internal structure.
