What are the types and wide applications of bentonite?

Bentonite is mainly divided into several types, such as sodium bentonite, calcium bentonite, hydrogen bentonite and organic bentonite, according to the difference of interlayer cations.

Sodium bentonite: It has excellent swelling, water absorption, adhesion and plasticity, and is the most widely used type of bentonite.

Calcium bentonite: Compared with sodium bentonite, its swelling and adhesion are slightly weaker, but the price is more economical, and it is suitable for some occasions with low performance requirements.

Hydrogen bentonite: It has special chemical properties and can exert unique properties under certain specific conditions, such as high temperature stability.

Organic bentonite: Through organic modification, it has better dispersibility, suspension and stability, and is suitable for high-end application fields.

Wide application of bentonite

The versatility of bentonite makes it play an important role in different fields, and its wide range of application fields is amazing.

Construction field: Bentonite is widely used in the production of building sound insulation and heat insulation materials, waterproof coatings, wall materials and other products due to its excellent expansion and adhesion, providing strong support for the green development of the construction industry.

Environmental protection field: Bentonite has a strong adsorption capacity and can adsorb harmful substances such as heavy metal ions and organic pollutants in water. It is an important material in the field of environmental protection. At the same time, bentonite can also be used in the construction of anti-seepage layers in landfills to effectively prevent the leakage of landfill leachate.

Metallurgical field: Bentonite is mainly used as a furnace lining material in the metallurgical industry. It is resistant to high temperature and erosion, and protects the furnace body from high-temperature slag.

Agricultural field: Bentonite has the function of improving soil structure and improving soil fertility. By adding bentonite, the air permeability and water retention of the soil can be improved, and crop growth can be promoted.

Foundry industry: Bentonite is used as a coating and adhesive in the foundry industry to improve the surface quality and strength of castings.

Food industry: Bentonite is mainly used for bleaching and purification in the food industry, such as decolorization of oils and fats, purification of sugar solutions, etc.

Oil drilling: Bentonite is an important raw material for oil drilling mud, which can adjust the viscosity, shear force and water loss of the mud and improve drilling efficiency.

Demand for bentonite powder making equipment

With the continuous expansion of bentonite application areas, the demand for bentonite powder making equipment is also increasing. When choosing grinding equipment, it is necessary to consider multiple factors such as equipment performance, production capacity, energy consumption and after-sales service.
