Clay bentonite MT. The bentonite.

Sell Bentonite is a mineral formations belonging to the class of aluminosilicates having a high dispersion, i.e. with the size of the crystals to less than 1 mBD. and, as a consequence of having a large specific surface area. Features crystal structure of bentonites determine the presence on the surface of ion exchangeable cations, which strongly influence the physico-chemical properties of minerals.
This:
- dispersion (small swelling) of the particles is faster and fuller than large;
- transportation of bentonite powder, especially at large distances is cheaper;
- mechanization and automation of processes for the preparation of solutions;
- other.

The quality of bentonitic powders and relating them to the various brands is determined, firstly, the quality of raw clay, and secondly, the methods of technological processing. In the production process may increase the quality of products (option) by treatment of clays with different reagents during grinding. Significantly improve the quality of bentonitic powders, for example, the introduction of soda ash Na2CO3 and acrylic polymers.

The effect of the modification is reflected in the increase of viscosity of clay suspensions due to the additional dispersion of clay, increasing the volume of bound water, the viscosity of the dispersion medium and the gain of gelation.

Depending on the application, the bentonitic powders must meet certain quality characteristics in accordance with the State Standards and Technical Conditions of the industry.

The scope of bentonite clay

Bentonite clay is one of the valuable minerals, which finds its application in various fields of human activity. Its other name - smectite, which is associated with the use of such clays for degreasing cloth. In modern industry, bentonite clay is used mainly in the steel industry for the formation of iron ore pellets and ready molding compounds. Not less important is the use of bentonite clays in the preparation of drilling and construction solutions, cleaning agents, oil, and also as raw material for the production of heat and waterproofing materials.
Bentonite mud powder in combination with refractory materials - the main raw material for the manufacture of natural molding compounds. Depending on the proportions of bentonite and perlite, such mixtures can have different properties. Molding compounds based on bentonite clay high durability, optimum gas-tight, with mild and environmentally friendly.

Bentonite clay is also known as Bancomat - material used for waterproofing of various objects. This material is very easy to operate and can be used in almost any weather conditions, including temperatures. Waterproofing shield, the composition of which contains bentonite clay, has a long life, maintains an almost unlimited number of cycles of hydration-dehydration and easily carries the seasons. An important property of waterproofing screen of bentonite is that the material is self-restored in the event of damage.
