Bentonite (clay powder)

Bentonite is a natural clayey hydroaluminosilicate containing at least 70% of montmorillonite group minerals with a high degree of dispersion. Bentonite PBMA is sodium bentonite from a mixture of high-quality clays from Russian deposits with the addition of soda ash, a product of drying and grinding highly colloidal clay raw materials from the Orenburg deposit according to the standard TU 39-0147001-105-93. The increased structural and mechanical properties of the clay suspension based on PBMV make it possible to use it for reclamation when eliminating absorption zones. PBMV grade bentonite clay powder can be used as a brightening component in cement slurries. Bentonite is a natural clayey hydroaluminosilicate containing at least 70% of montmorillonite group minerals with a high degree of dispersion. Natural bentonites typically have a pH of 6-9 and contain less than 2% sodium carbonate; the total content of interchangeable sodium and calcium does not exceed 80 me/100 g. Water penetrating into the interlayer space of the crystalline structure of bentonite hydrates its surface and exchange ions with free hydrogen ions, causing swelling of the mineral. By limiting the free space for swelling, a stressed state is created in the bentonite structure, which ensures low water permeability. Upon further dilution with water, bentonite forms a stable viscous suspension. Bentonite PBMA is sodium bentonite from a mixture of high-quality clays from Russian deposits with the addition of soda ash, a product of drying and grinding highly colloidal clay raw materials from the Orenburg deposit according to the standard TU 39-0147001-105-93. Gray powder. Activation of bentonite with soda ash is an effective way to increase the degree of swelling of bentonite while maintaining the optimal cost of the final product, compared to the activation of bentonite with polymers. APPLICATION The increased structural and mechanical properties of the clay suspension based on PBMV make it possible to use it for alluvium when eliminating absorption zones. PBMV grade bentonite clay powder can be used as a brightening component in cement slurries. Areas of application of clay powders based on PBMA bentonite: sorption reagents for the purification of food liquid media, natural, industrial and waste water. molding mixtures - in combination of bentonite with refractory materials. formation of iron ore pellets in metallurgy. waterproofing foundations in construction. obtaining drilling fluid for vertical and horizontal drilling. as slaughter cargo (feeding animals). brightening powder for wine industry. pet litter.
