Bentonite expanding and richest mineral which have wide usages from drilling to cosmetic
Bentonite is a material which is richest by aluminum and magnesium and includes montmorillonite. Usages of bentonite depends on their variety sodium calcium or magnesium and potassium has high expanding capacity can expand 10 times from its own size. Sodium bentonite uses in drilling while calcium kind use whitening agent in some of other.
Especially in drilling industry calcium bentonite is most effective material which need some additive for instance acid and soda for get best result during the process. CMC carboxyl methyl cellulose and acid uses in Activation process of calcium version
Usages of Bentonite
It is composing of montmorillonite expands with water and uses in drilling mud paint industry and some of other. another typical use of bentonite is as a mud constituent for oil and water well drilling. Its roles are principally to seal the borehole walls, to remove drill cuttings and to lubricate the cutting head It has different specification chemical properties for different usages. In drilling mud, it acts viscosity agent which remove the clays easily. It is used within the removal of impurities in oils wherever its adsorptive properties are crucial in the process of edible oils and fats (Soya/palm/canola oil). In brew, wine and mineral water, and in product like sugar or honey, it is employed as a clarification agent.
It also a water proof agent which is uses in construction. Uses in engineering applications is used traditionally as a thixotropic, support and lubricator agent in diaphragm walls and foundations, in tunneling, in horizontal directional drilling and pipe jacking, because of its viscosity and physical property, also is used in cement and mortars
Having purifying properties makes this product use in wine and juice. It is also animal food additive pharmacy paper making industry are the other areas of using of this mineral. It is good additive in cement and ceramic, oil well and water waste and in fertilize industry.
In cosmetic and medical it is used as filler in prescription drugs, and because of its absorption/adsorption functions, it permits paste formation. Such applications include industrial protecting creams, lotion, wet compresses, and ant irritants for skin disease. In drugs, bentonite is used as an cure in serious metal poisoning. tending product like mud packs, sunburn paint, baby and face powders, and face creams could all contain clay. It can apply laundry detergents and liquid hand cleansers/soaps rely on the inclusion of clay, so as to get rid of the impurities in solvents and to soften the fabrics.
Production process of bentonite
While production it has two steps. Except production process important section is drying, cracking grinding and activation process of bentonite which is spreading it after extract and using soda for activate it. It can crack without activation with special equipment. Some of additive material like sodium carbonate uses in activation for increase the quality. This method is mixes soda with moisture bentonite. This additive material type like soda depends of the usages of bentonite. For example, Ca can use with bentonite for purifying oil usages of bentonite. According to the final application, it is either sieved (granular form) or milled (into powder and super fine powder form). For special applications, it is s purified by removing the associated gangue minerals, or treated with acids to produce acid-activated it (bleaching earths), or treated with organics to produce organoclays.
This mineral acts like thickening and/or suspension agent in varnishes and water and solvent paints. Its sorption properties are appreciated for the finishing of indigo dying fabric, and in dyes (lacquers for paints & wallpapers).
