Talc has excellent physical and chemical properties such as lubrication, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, inactive chemical properties, good covering power, softness, good gloss, and strong adsorption. Due to the layered crystal structure of talc, it has a tendency to easily split into scales and special lubricity. If the content of Fe2O3 is high, its insulation will be reduced.
Talc is soft in texture, with a Mohs hardness coefficient of 1-1.5 and a sliding sensation. The {001} cleavage is extremely complete and easy to crack into thin slices. The natural resting angle is small (35 °~40 °) and extremely unstable. The surrounding rock is silicified and sliding magnesite, magnesite rock, poor ore or dolomite marble. Except for a few moderately stable rocks, they are generally unstable, with developed joints and fractures. The physical and mechanical properties of the ore and surrounding rock have a significant impact on the mining process.
Chemical grade
Usage: Used as a reinforcing and modifying filler in chemical industries such as rubber, plastics, paint, etc. Features: Increase the stability of product shape, increase tensile strength, shear strength, winding strength, pressure strength, reduce deformation, elongation, coefficient of thermal expansion, high whiteness, and strong particle size uniformity and dispersion.
Ceramic grade
Usage: Used for manufacturing high-frequency ceramics, wireless ceramics, various industrial ceramics, architectural ceramics, daily ceramics, and ceramic glazes. Features: High temperature non discoloration, enhanced whiteness after forging, uniform density, good gloss, and smooth surface.
Cosmetic grade
Usage: It is a high-quality filler in the cosmetics industry. Features: Contains a large amount of silicon element. It has the function of blocking infrared rays, thus enhancing the sun protection and anti infrared performance of cosmetics.
Medical and food grade
Usage: Used as an additive in the pharmaceutical and food industries. Features: It is non-toxic, odorless, with high whiteness, good compatibility, strong glossiness, soft taste, and strong smoothness. A pH value of 7-9 will not degrade the characteristics of the original product.
Paper grade
Usage: Used for products in various high and low grade papermaking industries. Features: Paper powder has the characteristics of high whiteness, stable particle size, and low wear. The paper made with this powder can achieve smoothness, delicacy, save raw materials, and improve the service life of the resin mesh.
Brucite powder
Usage: Used for manufacturing electric ceramics, wireless electric ceramics, various industrial ceramics, architectural ceramics, daily ceramics, and ceramic glaze. Features: High temperature non discoloration, enhanced whiteness after forging, uniform density, good glossiness, and smooth surface
