The difference between bentonite and montmorillonite and Application of montmorillonite in animal breeding

Bentonite is also known as bornite, bentonite or bentonite rock. The earliest discovery in the United States was that in the ancient strata of Wyoming, yellow green clay can expand into paste after adding water. Later generations collectively referred to all clays with this property as bentonite. Also known as universal clay, it is commonly known as Guanyin soil in China.

Montmorillonite is named for its original discovery in montmorillonite, France. Also known as microcrystalline kaolinite or Jiaoling stone, it is a silicate clay mine with layered structure and flake crystallization. Its chemical composition is quite stable, known as natural nano materials.

Definition of montmorillonite product in non-metallic mineral industry: if the content of montmorillonite in clay ore is greater than 80%, it is called montmorillonite, and its product content is mostly qualitative and quantitative by methods such as blue absorption. The other is the requirements of pharmaceutical and cosmetic industries for montmorillonite products, which is montmorillonite in the real sense. Its concept is close to the definition of montmorillonite in the field of scientific research, and its product content is mostly qualitative and quantitative by XRD and other methods.

Montmorillonite belongs to smectite group minerals. It is a non-metallic clay mineral, which is generally massive or earthy. The molecular formula (Na, CA) 0.33 (al, Mg) 2 [si4o10] (OH) 2 · nH2O is a clay mineral with three-layer lamellar structure composed of aluminum oxide octahedron in the middle and silicon oxygen tetrahedron at the top and bottom. The lamella carries negative charge, contains water and some exchange cations between the crystal structure layers, thus forming the unique dispersion, suspension, expansion, adhesion Select properties such as adsorption and ion exchange capacity.

The main functions of montmorillonite in animal breeding are to stop diarrhea, adsorb and fix mycotoxins and bacteria, repair damaged intestinal mucosa, and provide trace elements to promote animal growth. In recent years, with the implementation of the policy of banning resistance in the breeding industry, montmorillonite has been used more and more frequently in animal breeding because of its natural, green, non-toxic and non resistance, and the amount of addition has also increased.

Impurities and other hazards in montmorillonite: the impurities in montmorillonite are generally feldspar, carbonate, gypsum, quartz and other non-metallic minerals. These impurities do not have the crystal morphology and performance characteristics of montmorillonite, which will greatly reduce the adsorption and fixation effect of montmorillonite, which means that montmorillonite with low content can not play a good role in stopping diarrhea and adsorbing mycotoxins.
