What Is Talcum Powder? What Is Its Purpose?

Talc powder is an industrial product, which belongs to the talc group of magnesium silicate minerals. Its main component is hydrated magnesium silicate, which is crushed, treated with hydrochloric acid, washed with water, and dried. Commonly used as fillers for plastic and paper products, rubber fillers and anti sticking agents for rubber products, advanced paint coatings, etc. The main component of talc is magnesium silicate containing water, with a molecular formula of Mg3 [Si4O10] (OH) 2. Talc belongs to the monoclinic crystal system. Crystals appear as pseudo hexagonal or rhombic flakes, occasionally seen. Usually formed into dense block like, leaf like, radial, or fibrous aggregates. Colorless, transparent or white, but appears light green, light yellow, light brown or even light red due to the presence of a small amount of impurities; The cleavage surface has a pearl luster. Hardness 1, specific gravity 2.7-2.8. characteristic: It has excellent physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power, softness, good luster, strong adsorption power, etc. Due to the layered crystalline structure of talc, it has a tendency to easily split into scales and special lubricity. Under normal circumstances, it is relatively stable with no obvious side effects, but long-term ingestion in large quantities can be carcinogenic. According to GB 9685-2008, the maximum usage amount in coatings is 2.0%; Use appropriate amounts of plastic (PE, PP, PS, AS, ABS, PA, PET, PC), rubber, and paper according to production needs. Specifications: 200 mesh, 325 mesh, 500 mesh, 600 mesh, 800 mesh, 1250 mesh to 8000 mesh, etc. The extracted talc (raw material for talc powder) can be directly crushed using a Raymond mill or other high-pressure mill after selecting high-quality talc. It can be packaged in woven bags (50kg, or 25kg specification woven bags) and sold as finished products. In ter
