The properties of montmorillonite are closely related to the types of exchangeable cations between layers. According to the types of main exchangeable cations between layers, montmorillonite is generally divided into calcium montmorillonite and sodium montmorillonite.
Montmorillonite has adsorption and cation exchange properties, and can be used to remove toxins from edible oils, purify gasoline and kerosene, and treat wastewater; Due to its excellent water absorption and expansion properties, as well as its dispersion, suspension, and slurry making properties, it is used in drilling mud, flame retardant (suspension fire extinguishing); It can also be used as a filler in the paper industry to optimize the performance of coatings such as adhesion, covering power, water resistance, washing resistance, etc; Due to its excellent adhesion, it can be used instead of starch for yarn sizing in the textile industry, which not only saves grain, but also does not cause fuzzing, and does not emit a peculiar smell after paddling. It is truly a win-win result.
In general, the properties of sodium montmorillonite (or sodium bentonite) are better than those of calcium.
Due to its excellent physical and chemical properties, bentonite (montmorillonite) can be used as a purifying and decolorizing agent, adhesive, thixotropic agent, suspension agent, stabilizer, filler, feed, catalyst, etc. It is widely used in agriculture, light industry, cosmetics, pharmaceuticals, and other fields. Therefore, montmorillonite is a widely used natural mineral material.
Bentonite can be used as waterproof materials, such as bentonite waterproof blankets, bentonite waterproof boards, and supporting materials, which are paved using mechanical fixation methods. It should be used in underground environments with pH values of 4 to 10, and environments with high salt content should use modified bentonite, which should be tested and used after passing the test.
