[0002] Bentonite is also called bentonite, soap clay or bentonite rock. my country has a long history of developing and using bentonite. It was originally just used as a detergent, and it has only been widely used for a hundred years. The United States first discovered it in the ancient strata in Wyoming. It is a yellow-green clay that can swell into a paste after adding water. Later, people called all clays with this property bentonite. In fact, the main mineral component of bentonite is montmorillonite, with a content of 85-90%. Some properties of bentonite are also determined by montmorillonite. Montmorillonite can be various colors such as yellow-green, yellow-white, gray, white, etc.
