The nature of montmorillonite is strongly related to the type of exchangeable cation between the layers. According to the type of interlayer exchangeable cations, usually montmorillonite is divided into calcium montmorillonite and sodium montmorillonite.
Montmorillonite has adsorptive and cation exchange properties, can be used to remove cooking oil toxins, gasoline and kerosene purification, wastewater treatment; due to good water swelling properties and dispersion and suspension and slurrying, it is used in drilling mud, Flame-retardant (suspended fire); also can be used in the paper industry filler, coating properties can be optimized such as adhesion, hiding power, water resistance, washability, etc .; due to good adhesion, can be used instead of starch The yarn sizing in the textile industry not only saves grain, but also does not raise hair, does not emit odor after paddling, and it is really double benefit.
In general, sodium montmorillonite (or sodium bentonite) is better in nature than calcium.
Bentonite (montmorillonite) is widely used in agriculture, light industry and cosmetics due to its good physicochemical properties, such as decontamination, binders, thixotropic agents, suspending agents, stabilizers, filling materials, , Medicines and other fields, montmorillonite is a versatile natural mineral materials.
Bentonite can be used for waterproofing materials, such as bentonite waterproof blanket, bentonite waterproof board and its supporting materials, the use of mechanical fixed laying method. Applied to the PH value of 4 to 10 underground environment, salt content higher environment should be modified bentonite, and should be used after testing qualified.
In 1898, American geologist Knighl discovered a greenish-yellow water-swelling clay material near the Rocky Mountain, Wyoming, USA, and named Betonite because of "Fort Beton". Bentonite is also called bentonite or bentonite. The main mineral of bentonite is montmorillonite. The content of high grade is 85-90%. Some properties of bentonite are also determined by montmorillonite.
Montmorillonite can be various colors such as yellow-green, yellow-white, gray, white and so on. Can become a dense block, but also for the loose soil, rubbing with a finger when there is a sense of slip, a small body of water after the bulging volume, was suspended in water, less water was pasty. Montmorillonite adsorption and cation exchange performance, can be used to remove oil toxins, gasoline and kerosene purification, wastewater treatment.
