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.
