Application and characteristics of industrial talc powder

Industrial talc powder: used for manufacturing high frequency porcelain, wireless porcelain, various industrial ceramics, architectural ceramics, daily ceramics and ceramic glaze, etc. Features: no discoloration at high temperature, enhanced whiteness after forging, uniform density, good gloss, smooth surface.

Super fine powder, widely used in rubber, papermaking, coating, plastic, aluminum, ceramics, cement, glass, metallurgy, refractory materials, medicine, food, daily chemicals, cosmetics, craft production application fields such as architecture, senior decoration. Especially when applied to coating and papermaking, the usage of titanium dioxide can be reduced by 3% to 10% directly, thus greatly reducing the product cost. High quality Chinese white jade (dolomite) super fine stone powder paper industry used in the pulp adding (plywood paper, copper sheet paper, etc.), its role is to increase opacity, improve paper flexibility.

Stone powder is the general name of stone powder. There are many kinds of stone. There are many kinds of stone according to mineral composition, not necessarily calcium carbonate. Calcium carbonate is limestone, just one of the powders, and talc is used to make putty. Quartz powder is also used to make glass. There are also many minerals in rocks that can be ground into powder for different processes and USES.

Talc with lubricity, sticky, flow resistance, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power and soft, good luster, strong adsorption force and other excellent physical and chemical properties, due to the crystallization of talc is a layered structure, so the easier to split into flake trends and special lubrication, if the content of Fe2O3 high will reduce its insulation.

Talc soft, its for 1 ~ 1.5 mohs hardness coefficient, have slippery feeling, cleavage is extremely full, easy to split into slices, natural rest Angle is small, very solid, the surrounding rock of silicide and petrochemical magnesite, lingmei rocks, lean ore or dolomitic marble, with a few solid medium, generally are not solid, joint, crack development, physical and mechanical properties of the ore and surrounding rock is a big influence on mining process.

Synovial monoclinal system. The crystal is a hexagon or rhomboid plate, but the intact crystal is rarely seen, usually a granular and scale-like dense mass. Pale green, white or gray. The stripes are white or pale green. Glossy fatness. The cleavage surface is pearl-shaped. Translucent to opaque. The cleavage is complete along the bottom. Hardness 1, specific gravity 2.7 ~ 2.8. Sex is soft. It feels greasy. A talc can be sawn into any shape, the sheet can bend, but it is inelastic. It is mainly produced in metamorphic rocks, limestone, dolomite, magnesite and shale.
