Our products, which are produced in 4 grades in our mine in Eskişehir, are crushed in our facilities and are regularly exported to more than 30 countries, especially Italy, Spain, Russia and India, in big bags to be used in cat litter, drilling industry, cosmetics industry, food industry and tile production. .

Bentonite is used for drilling mud, binders (binders for foundry sands, iron ore pellets), water purifiers, adsorbents (such as cat litter), or barriers to protect groundwater.

 Drilling fluid

Bentonite is used in drilling fluids to lubricate and cool cutting tools to remove debris and prevent blowouts. Bentonite can be used in drilling and geotechnical engineering mainly due to its unique rheological properties. A small amount of bentonite is suspended in water to form a viscous, shear-thinning material. In most cases, bentonite suspensions have thixotropic properties, and the related reported segregation behavior is rare. When the concentration is large (60 g of bentonite per liter of suspension), the bentonite suspension begins to exhibit gel properties (the fluid has the minimum yield strength required to move it). For the above reasons, bentonite has become a commonly used additive in drilling fluids, helping to form mud cakes and reducing the infiltration of drilling fluids.

Binder

Bentonite has been widely used as a foundry sand binder in the steel foundry industry. Sodium bentonite is commonly used in large castings used in dry molds, while calcium-based bentonite is commonly used in small castings used in “green” or wet molds.

Bentonite is also used as a binder in the manufacture of iron ore (iron meteorite) pellets in the steelmaking industry. Bentonite, when used at lower levels, can also be used as a component in commercially available clay bodies and ceramic glazes.

The ionic surface properties of bentonite make it an important application in the preparation of adhesive coatings on the surface of sand. When a small portion of the finely ground bentonite is added to the hard sand and wetted, the clay forms a formable aggregate called wet sand with the sand, which is used in the sand mold manufacturing mold. The delta regions of some rivers form a mixture of such clay silt and sand under natural conditions, forming a source of fine sand, which is a key factor in ancient metalworking technology. Modern chemical processes greatly enhance this viscosity by modifying the surface of the bentonite ions, allowing the pelletized and robust foundry sand mixture to withstand the temperature of financial melting.

Purifier

Bentonite can be used for the decolorization of various mineral oils, vegetable oils and animal oils. It can also be used for clarification of wine, spirits, cider, beer, vinegar and other edible liquids.

Bentonite has the ability to adsorb larger proteins from aqueous solutions. Therefore, bentonite has a special use in the wine making process, for example, removing excess protein from white wine. If bentonite is not used, many or most white wines exposed to higher temperatures will precipitate and poorly flocculate due to protein denaturation. It is also occasionally used for quick clarification of red and white wines.

Adsorbent

Bentonite can be used in a variety of pet care products, such as cat litter to absorb unpleasant odors and feces. It can also be used to absorb oil and grease.

Impervious material

The property of swelling after contact with water allows sodium bentonite to act as a sealant because it provides a self-sealing, low permeability barrier. He can be used as a landfill anti-seepage material to prevent leachate migration, to isolate heavy metal ions, to prevent contamination of groundwater, and to seal nuclear waste underground treatment systems. The same application also includes wall slurry, waterproofing of underground walls, forming other impervious barrier layers, such as seal rings for wells.

Of course, bentonite can also be used as a “sandwich” of synthetic materials to make geosynthetic clay liners (GCL) for the above purposes. This technology enables more efficient transportation and installation, effectively reducing the required volume of bentonite.

Bentonite can also be used to form barriers on newly planted trees to constrain the growth of roots and to prevent damage to nearby pipes, sidewalks and other infrastructure. Farmers can also use Pengrun soil as a barrier layer to preserve ponds.

Medicine

Bentonite has been designated as a bulk laxative and is also used as a base material in the formulation of dermatological drugs. Bentonite particles are also in the research stage as wound dressings on the battlefield.

Bentoquatam is a topical application of bentonite as a protective layer to prevent exposure to urushiol (oil found in poison ivy and poison oak).

Bentonite can also be used as a desiccant due to its excellent adsorption properties. Bentonite desiccant is successfully used to protect drugs, health products and diagnostic products from deliquescence and prolong the shelf life of the product. In fact, in the most common packaging environments, bentonite has a higher adsorption capacity than silica gel desiccant. Bentonite also meets the requirements of the US Food and Drug Administration for contact between food and medicine.
