What use does Peng Runtu have?
The properties of montmorillonite are closely related to the exchangeable cation species between layers. According to the types of the main exchangeable cations between layers, the montmorillonite is usually divided into calcium montmorillonite and sodium montmorillonite.Montmorillonite adsorption and cation exchange properties, which can be used to remove oil, gasoline and kerosene toxin purification, wastewater treatment; water absorption due to good swelling properties and dispersion and suspension and mud, so used for drilling mud, flame retardant (suspended fire); also can do filler in papermaking industry, optimization the coating properties such as adhesion, covering power, water resistance and washing resistance; because it has good cohesive force, can replace the starch used in the textile industry in both grain and yarn sizing, non pilling, smell is not a paddle, is really a must.
Bentonite is also called bentonite and bentonite rock. The development and use of bentonite in China has a long history, but it was only used as a kind of detergent. (in Sichuan Renshou area, there was an open-air mine hundreds of years ago, and the local people called bentonite as earth powder). What is widely used but only a few hundred years of history. The earliest discovery in the United States was the yellowish green clay in Wyoming's ancient state, which expanded into a paste after adding water. Later, people referred to all these clays as "bentonite". In fact, the main mineral composition of montmorillonite is montmorillonite, the content is 85-90%, and some properties of bentonite are also determined by montmorillonite. Montmorillonite can be a variety of colors, such as yellow green, yellow white, gray, white and so on. Can be dense, massive, or for loose soil, with fingers rubbed when there is a sense of sliding, small pieces of water after the volume of swelling several times to 20-30 times, in the water as a suspended shape, less water when it was mushy. The properties of montmorillonite are related to its chemical composition and internal structure.
Bentonite is an aqueous clay mineral dominated by montmorillonite. The chemical composition of montmorillonite is (Al2, Mg3) [Si4O10][OH]2, nH2O, because of its special properties. Such as: swelling, adhesion, adsorption, catalysis, thixotropy, suspension and cation exchange, etc., so widely used in various industrial fields. Foreign countries have been applied in more than 100 sectors of industry, agriculture and production in 24 fields, and there are more than 300 products, so people call it "omnipotent soil"".
