Product Description

Product Description

Bentonite is a non-metallic mineral with montmorillonite as its main mineral composition. Montmorillonite structure is composed of two silica tetrahedrons sandwiched by a layer of aluminum oxide octahedron2: Type 1 crystal structure, because there are some cations in the layered structure formed by montmorillonite cells, such as Cu, Mg, Na, K, etc., and the interaction of these cations with Montmorillonite cells is very unstable, easy to be exchanged by other cations, so it has good ion exchange.
 

 

 

Bentonite is also called bentonite, bentonite or bentonite. China has a long history of developing and using bentonite, which was originally only used as a detergent. (The Renshou area of Sichuan Province has had open-pit mines for hundreds of years, and locals call bentonite soil powder.) It's only been in widespread use for a hundred years or so. The United States was first found in the ancient formation of Wyoming, yellow-green clay, after adding water can expand into a paste, and later people put all the clay with this property, collectively referred to as bentonite. In fact, the main mineral composition of bentonite is montmorillonite, the content is 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. Can be a dense block, can also be loose soil, with fingers rubbing slippery, small pieces of water after the volume expansion several times to 20-30 times, in the water is suspended, when the water is mushy. The properties of montmorillonite are related to its chemical composition and internal structure.

Application

Drillingbentonite: Bentonite is the main material of the preparation of slurry. It has the effection of protecting sidewall,
upward returing cuttings, cooling and lubricating the bits.

Foundry bentonite: Bentonite is used in agglomerant and lithium bentonite is used in quick-drying coating.

Iron core pelletizing bentonite: It can improve the production capacity by adding 1-2% sodium bentonite in the refined
iron-mineral powders. It is widely used in steel mills.

Coating bentonite:Bentonite is used as suspending agent in various coating. It can improve the suspension, adhesion, brushing property and water resistance of the coating.

Animal feed bentonite: Bentonite can be used as additives of animal feed because it contains a lot of microelements such as Fe, Cu, Zn and Mn and it's non-toxic and fine powder.

Fertilizer bentonite: It can improve the fertilizer effection and improve the soil.

Building bentonite: Bentonite has good effection of anti-leakage in construction.

Rubber bentonite: Bentonite has better swelling rate,high water absorption.
