Talc has excellent physical and chemical properties such as lubricity, anti-adhesion, flow-assisting, refractory, acid resistance, insulating, high melting point, chemical inactivity, good covering power, soft, glossy, strong adsorption, etc. Because the crystalline structure of talc is layered, so it has the tendency to split into scales easily and a special slipperiness, and if the content of Fe2O3 is very high, then it will reduce its insulating properties.
Slippery
Talc is soft, its Moh's hardness coefficient of 1 ~ 1.5, slippery, {001}decomposition is very complete, very easy to split into flakes, the natural angle of repose is small (35 ° ~ 40 °), extremely unstable, the surrounding rock for the silica and slippery petrochemical magnesite, magnesia, poor or dolomitic marble, in addition to a small number of moderately stable, generally unstable, joints, fissures are developed, the physical properties of the ore and the surrounding rock. The mechanical properties of the ore and surrounding rock have a great influence on the mining process.
Chemical grade
Use: Used in rubber, plastics, paints, and other chemical industries as a reinforcing and modifying filler. Characteristics: Increase the stability of the shape of the product, increase the tensile strength, shear strength, flexural strength, pressure strength, reduce deformation, elongation, coefficient of thermal expansion, high whiteness, particle size uniformity dispersion and other characteristics.
Ceramic grade
Use: Used in the manufacture of high-frequency ceramics, radio ceramics, all kinds of industrial ceramics, construction ceramics, daily-use ceramics and pottery glaze. Characteristics: no color change at high temperature, enhanced whiteness after forging, uniform density, good luster and smooth surface.
Cosmetic grade
Use: It is a high quality filler for cosmetic industry. Characteristics: It contains a large amount of silicon. It has the effect of blocking infrared rays, so it enhances the sunscreen and anti-infrared performance of cosmetics.
Pharmaceutical and Food Grade
Use: It is used as an additive in pharmaceutical and food industries. Characteristics: non-toxic, odorless, high whiteness, good tolerability, gloss, soft taste, smoothness characteristics. pH value of 7-9, will not degrade the characteristics of the original product.
Paper grade
Use: Used in a variety of high and low grade paper industry products. Characteristics: The papermaking powder is characterized by high whiteness, stable particle size and low abrasion. The paper made by using this powder can achieve smooth and delicate paper, save raw materials, and improve the service life of fat mesh.
Water magnesite powder
Use: used in the manufacture of electric porcelain, radio ceramics, all kinds of industrial ceramics, construction ceramics, daily-use ceramics and pottery glaze. Characteristics: no color change at high temperature, enhanced whiteness after forging, uniform density, good gloss, smooth surface.
