Description

Bentonite is the mineral educations belonging to the class of aluminosilicates, having high dispersion, i. e. possessing crystals in size at the level of less than 1 mkn. and, thereof, having a big specific surface. Features of a kristallokhimichesky structure of bentonites cause availability on their surface of the ion - exchange cations which enough are strongly influencing physical and chemical properties of minerals.


Practically two names appear in all technical editions of the beginning of the 20th century by consideration of bentonites: fullerova of the earth and bentonites. To fullerovy lands since ancient times (since the Roman Empire) carried the clays possessing ability to absorb dispersion particles of the different sizes. Such clays used for purification of the wool used for cloth production of fat. Fuller or fuller in the English transcription is translated as suknovat. Afterwards it has been established that in the nature two types of fulling clays meet. Clays of one type were used as fulling in a natural look, another after chemical treatment or activation. Large accumulations of clays of the second type have been found near a fort Benton (USA) and have received the name bentonite. Later mineralogical researches have shown, as "earth fullerova" and bentonites have almost identical mineral composition.

Standard chemical composition of bentonite, %

Al2O3 16, 55 K2O 0, 92
SiO2 52, 30 Na2O 1, 92
TiO2 0, 95 P2O5 0, 12
CaO 5, 49 MgO 3, 03
Fe2O3 5, 2 S 0, 36

Bentonite powder represents a product of drying and a high milling of natural material - the bentonite clay which has kept all the colloid and chemical properties. Dry muds have a number of advantages before lump clays. It:


- dispersion (swelling small) particles happens quicker and more stoutly, than large;
- transportation of a dry mud, especially on long distances costs cheaper;
- mechanization and automation of processes of preparation of solutions;
- others.

Quality of bentoporoshk and their reference to different brands is defined, first, by quality of initial clay, secondly, methods of technology processing. In production process improvement of quality of dry muds (modification) by processing of clays different reagents is possible during a grinding. Considerably improve quality of bentoporoshk, for example, introduction of Na2CO3 soda ash and acrylic polymers.


The effect of modification is expressed in increase of viscosity of clay suspension due to additional dispersion of clay, increase in volume of a bound water, viscosity of a disperse medium and strengthening of gelation.


Depending on application, bentoporoshka should answer certain qualitative characteristics according to State Standards and Specifications of this industry.

Scopes of bentonite clay

Bentonite clay - one of valuable fossil materials which has found the application in the most different areas of human activity. Other its name - fulling clay that is connected with use of such clays for cloth degreasing. In the modern industry bentonite clay is used, mainly, in metallurgy - for forming of iron ore pellets and an izgotovka of a sand. Use of bentonite clay at preparation boring and grouts, means of purification of oil products, and also as raw materials is not less important for production of warm and hydraulic insulating materials.

Purely bentonite clay is used seldom, most often in the industry and other areas of economy bentonite dry muds are applied. This material is received by drying and fine crushing of bentonite clay. Bentonite dry muds add to composition of polymeric materials, add to concrete that increases their vodoadgediozny properties. On the basis of bentonite powder the most available boring mixes at cost possessing, besides, by high operational properties and the providing excellent results are made at vertical or horizontal drilling.

Bentonite dry muds in combination with refractories - the main raw materials for production of a natural sand. Depending on proportions of a dry mud and perlites, such mixes can possess different properties. A sand on the basis of bentonite clay differs in high strength, optimum gas - tightness, at the same time is easily formed and is ecologically pure.

Bentonite clay is known also as bentomat - the material used for a waterproofing of different objects. This material is very convenient in operation and can be applied practically under any weather conditions, including - at negative temperatures. The waterproofing board as a part of which there is a bentonite clay has the long term of operation, maintains almost unlimited number of cycles of hydration dehydration and easily transfers change of seasons. Important property of the waterproofing screen consists of bentonite that material is independently recovered in case of receiving damage.
