Product discription

Bentonite is an aqueous natural clay mineral mainly composed of montmorillonite

Chemical component

Bentonite is also called bentonite bentonite. Chemical composition of bentonite: bentonite is mainly composed of montmorillonite, and the content of montmorillonite is 85-90%.The clay minerals associated with montmorillonite include illite, kaolinite, haloite, chlorite, hydroaluminite and some interbedded clay minerals. The non-clay minerals associated with montmorillonite include quartz, feldspar, zeolite, gypsum, calcite, pyrite and so on. The chemical formula of montmorillonite is :Al2O3.4SiO2.3H2O;The main
chemical composition is silicon dioxide 3 oxide 2 aluminum and water, but also contains iron magnesium calcium sodium potassium and other elements

Physical property

The bentonite mainly has white cheese color, light gray, light yellow-green meat, red brick, red, light red, maroon and black
mottled color.Most of them are dense and hard blocks, a few are earthy, and the ones with strong swelling force are porous or foamlike on the outcrop.A waxy or earthy sheen;Opacity hardness 2.0~2.5;The proportion of 2.0 ~ 2.7;Melting point 1330~1430 bentonite has water absorption, expansion, bonding, adsorption, lubrication, catalytic activity, thixotropic plasticity and cation
exchange properties. According to the types, content and crystalline chemical properties of interlayer exchangable cations contained in montmorillonite, bentonite can be divided into sodium-based, calcium-based, magnesium-based and calcium-basedSodium bentonite and other different types.
Application

Development and application

Bentonite has good physical and chemical properties, enjoy the "universal clay" reputation in the world, it is mainly used for
casting sand, mud, civil engineering and construction for iron ore pellets, and the animal and poultry feed, etc., can be used as purifying bleaching agent, binder, thixotropic agent, suspending agent, stabilizer, filling material, catalyst, etc., widely used
in agriculture, light industry and cosmetics, medicine and other fields,It is a kind of natural mineral material with a wide range
of uses.
