Application
Bentonite is applied to preparation of a drilling fluid. It is applied in foundry business, when processing oil products and iron ores, in production of ceramics, to lighting of solutions.
Bentonite is biologically active agent, its addition in a forage and with fertilizers to the soil increases productivity of animals and productivity of agricultural cultures.
Basic component of bentonite is montmorillonite which after modification is used in the oil and gas, food, cosmetic, pharmacological and construction industries.
Bentonite is also applied to dressing of a different type of terrariums, palyudarium, aquariums and other devices for keeping of amphibious and other representatives of water elements in house conditions.
Application in winemaking
In winemaking bentonite is used for acceleration of lighting of a mash, wine materials and stabilization of wines against proteinaceous opacifications.
Bentonite is set in wine material in the form of 20% water suspension at the rate of 1 — 4 g/l. The dose is defined by carrying out trial pasting. Usually production processing of B. is combined with a demetallization, pasting by gelatin or polyvinylpirrolidone. For acceleration of formation of a deposit add polyacrylamide or polyoxyethylene. When lighting a mash bentonite increases the speed of sedimentation of the stirring-up particles, adsorbs oxidizing enzymes, deletes microorganisms, reduces amount of protein, etc. substances.
