The English name for talc powder is PULVISTALCI, also known as hydrated magnesium silicate ultrafine powder in Chinese,
It is a white or off white, fine, non sandy powder that feels greasy when touched by hand. Odorless,
Odorless. This product is insoluble in water, dilute mineral acid, or dilute hydroxide alkali solution. Can be used as medicine
Use it. This product is a magnesium silicate mineral talc group talc, mainly composed of hydrated silicic acid
Magnesium is crushed, treated with hydrochloric acid, washed with water, and dried.
The main component of talc is magnesium silicate containing water, with a molecular formula of Mg3 [Si4010] (0H) 2. Talc belongs to the monoclinic crystal system. crystal
Form a false hexagonal or diamond shaped sheet, occasionally seen. Usually formed into dense block like, leaf like, radial, or fibrous aggregates. Colorless and transparent
Bright 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. hard
Degree 1, specific gravity 2.7~2.8.
Talc has lubricity, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, and covering properties
Excellent physical and chemical properties such as good strength, softness, luster, and strong adsorption, due to the layered crystalline structure of talc
Therefore, it has a tendency to easily split into scales and special lubricity. If the content of Fe203 is high, it will reduce its insulation
Sex. Talc powder specifications: 200 mesh, 325 mesh, 500 mesh, 600 mesh, 800 mesh, 1250 mesh, etc.
