Talcum lump
English PULVISTALCI talcum powder called white or kind of white, subtle, no sand sex of powder, hands have greasy feeling. Odourless and tasteless. This product in water, dilute mineral acid or dilute alkali solution in hydrogen oxidation are not dissolve. Can make medicinal.
Talc main component is water cut of talc magnesium silicate , formulas for Mg3 [Si4O10] (OH) 2. Talc single crystal of the department. Crystal is false of the six party or the diamond of sheets, I see. Usually in a dense block, leaf shape, radial shape, fibrous aggregation. Colorless transparent or white, but because it contains a small amount of impurities and shallow green, yellow, subtle stitching present even light red; A pearl luster cleavage plane. Hardness 1, specific gravity of 2.7 ~ 2.8. Talc lubricity, fight with sticky, assist flow resistance, resistance to acid, watery, insulation, high melting point, chemical not lively, covering power is good, soft, gloss, strong absorption affinity of excellent physical and chemical characteristics, because the talc crystal structure is a layer, so has the easy split into the scales of the trend and special lubrication sex, if high levels of Fe2O3 will cut its insulation.
Talcum powder specification: 200 mesh 325 mesh 500 mesh 600 mesh 800 mesh 1250 item such as classified chemical class talcum powder use: for rubber, plastic, paint, such as chemical industry to strengthen the quality as the filling agent.
