Product Overview:
Talc powder, white or almost white, fine, non-sand powder, hand feel greasy, odorless, tasteless. The main component of talcum powder is talc, which is crushed, treated with hydrochloric acid, washed with water and dried. It is insoluble in water, dilute mineral acid or dilute alkali hydroxide solution and can be used for medicinal purposes. Talc powder can be divided into chemical grade talcum powder, ceramic grade talcum powder, cosmetic grade talcum powder, medicine, and food grade talcum powder according to the purpose and grade.
Product ingredients:
The main component of talc is talc containing hydrous magnesium silicate with the molecular formula Mg3[Si4O10](OH)2. Talc is monoclinic. Crystals are pseudo-hexagonal or diamond-shaped flakes, occasionally seen. Usually a dense block, leaf, radial, fibrous aggregates. Colorless, transparent or white, but light green, light yellow, light brown or even light red due to a small amount of impurities; Hardness 1, the proportion of 2.7 to 2.8.
Features:
Talc has excellent physical and chemical properties such as lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, strong adsorption, etc., due to talc The crystalline structure is layered, so it has a tendency to split into flakes and a special lubricity. If the content of Fe2O3 is high, it will reduce its insulation.
