What are the main components of bentonite and what are the main uses of bentonite

Bentonite is a water-bearing clay ore dominated by montmorillonite, and the chemical composition of montmorillonite is: (Al2,Mg3)[Si4O10][OH]2 6 1NH2O, because it has special properties. Such as:

It is widely used in various industrial fields due to its sweltering, cohesiveness, adsorption, catalysis, thixotropy, suspension, and cation exchange. Bentonite is a non-metallic mineral with montmorillonite as the main mineral component, and the montmorillonite structure is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedra sandwiched with a layer of aluminum-oxygen octahedron [1], because there are certain cations in the layered structure formed by montmorillonite unit cells, such as Cu, Mg, Na, K, etc., and the effect of these cations and montmorillonite unit cells is very weak, and it is easy to be exchanged by other cations, so it has good ion exchange.

It has been applied in more than 100 departments in 24 fields of industrial and agricultural production abroad, with more than 300 products, so people call it "universal soil".

Bentonite. According to the transliteration, it is montmorillonite.

Mainly water-bearing clay mine, due to its special properties. Such as: swelling, cohesiveness, adsorption, catalysis, thixotropy.

and cation exchange, so it is widely used in various industrial fields. Xiangyang Baishishan White Clay **** is mainly engaged in the mining and processing of bentonite ore and the sales of bentonite products. The company covers an area of 5,000 square meters, under two production bases, Baima Mountain, Yushan Damiao Village, with high-quality bentonite main mine and contract mines, recoverable reserves of more than 10 million tons, the company has formed an annual mining and product processing capacity of 150,000 tons.

Our product is a white filler for compound fertilizer, and the color of the compound fertilizer is relatively white, crystal round, and granular. Inquiry**: 13995733559 Manager Bing.

Kid stupid! You go, you won't know if you search it. Brother Yong told you how to get on**? Ha ha.

The main uses of bentonite are:

1. Bentonite is mainly used in clay cohesive sand, which has high plasticity, strong cohesion, good air permeability, and stable physical and chemical properties under high temperature conditions.

2. To make drilling mud, the main component of bentonite is montmorillonite, which is a non-metallic mineral with strong water absorption, and mud needs to be used for operation in oil and gas drilling and other work.

3. Granular clay can be processed, which can be used for sewage treatment and toxic gas filtration.

4. The desiccant is made with faster adsorption speed and high adsorption capacity, and this desiccant is tasteless and non-toxic, and can be used in food packaging without threatening human health.

Characteristic. Bentonite, also known as porphyrite, bentonite or bentonite, is a non-metallic mineral with montmorillonite as the main mineral component, generally white, light yellow, light gray, light green, pink, brown, brick red, gray-black, etc. Hardness 1 2, density 2 3g cm3.

According to the type, content and layer charge of montmorillonite exchangeable cations, bentonite can be divided into sodium bentonite (alkaline soil), calcium-based bentonite (alkaline soil), natural bleached soil (acidic soil or acidic white clay), of which calcium-based bentonite includes calcium sodium base and calcium magnesium base.

Bentonite (montmorillonite) can be used as purification and decolorizing agent, binder, thixotropic agent, suspension agent, stabilizer, filler, feed, catalyst, etc., and is widely used in agriculture, light industry, cosmetics, pharmaceuticals and other fields, so montmorillonite is a natural mineral material with a wide range of uses.

Bentonite can be used as waterproof materials, such as bentonite waterproof blanket, bentonite waterproof board and its supporting materials, which are laid by mechanical fixation. Montmorillonite has adsorption and cation exchange properties, and can be used to remove toxins from edible oil, purification of gasoline and kerosene, and wastewater treatment.

Exploration studies have shown that China's bentonite reserves are the first in the world, with complete types and wide distribution, covering 26 provinces and cities, and ranking among the top in the world in terms of output and export. According to incomplete statistics, the annual output of bentonite in China has exceeded 3.5 million tons, and the total reserves account for 60% of the world's total. So far, it has accumulated more than 5,087 billion tons of proven reserves, and more than 7 billion tons of reserves.

Bentonite is a non-metallic mineral with montmorillonite as the main mineral component, montmorillonite structure is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedra and a layer of aluminum-oxygen octahedron, because there are some cations in the layered structure formed by montmorillonite unit cells, such as Cu, Mg, Na, K, etc., and the effect of these cations and montmorillonite unit cells is very unstable, and it is easy to be exchanged by other cations, so it has good ion exchangeability. It has been applied in more than 100 departments in 24 fields of industrial and agricultural production in foreign countries, and there are more than 300 products, so people call it "universal soil".

Bentonite is also called porphyry, bentonite or bentonite. China has a long history of developing and using bentonite, which was originally only used as a detergent. (There were open-pit mines in the Renshou area of Sichuan hundreds of years ago, and the locals called bentonite powder).

In fact, the main mineral component of bentonite is montmorillonite, with a content of 85-90%, and some properties of bentonite are also determined by montmorillonite. Montmorillonite can be in a variety of colors such as yellow-green, yellow-white, gray, white, and so on. It can be a dense block, or it can be loose soil, there is a slippery feeling when rubbing with fingers, and the volume of small pieces expands several times to 20-30 times after adding water, and it is suspended in water, and it is pasty when there is less water.

The properties of montmorillonite are related to its chemical composition and internal structure.

Because bentonite has excellent suspension, cohesiveness and dispersion. It is used as a suspending agent in water-soluble coatings, anti-road water coatings, emulsified asphalt coatings, thermal insulation coatings, anti-corrosion, fire prevention and other coatings, which can greatly improve the suspension, internal adhesion, brushability and water resistance of coatings. In the ash, bentonite and heavy calcium powder are used to prepare the seed paste.

Low cost and good effect.

Application of bentonite: bentonite is known as "all-purpose" clay due to its good physical and chemical properties, and can be used as a binder, suspension agent, thixotropic agent, stabilizer, purification and decolorizing agent, filler, feed, catalyst, etc., which is widely used in metallurgy, petroleum, foundry, food, chemical industry, environmental protection and other industrial sectors.
