?Paint with superfine talc afghanistan Osmanthus brand
?
Talc is the main component of magnesium containing magnesium silicate, molecular formula for Mg3[Si4O10] (OH) 2. Talc is in the form of a single crystal. Crystal is six square or diamond shape, I see. Usually into a dense block, blade like, radial, fibrous aggregate. Colorless or white, but with a small amount of impurities and has light green, light yellow, light brown or pale red; the cleavage plane is Pearl luster. Hardness 1, specific gravity of 2.7 ~ 2.8.
Talc lubricity, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power and soft, good gloss, strong adsorption capacity, excellent physical and chemical properties, the crystal structure of talc is a layer, so it is easy to split into scales the trend and special lubrication, if the Fe2O3 content is very high will reduce its insulation.
Talc is soft, the Mohs hardness coefficient is 1 ~ 1.5, with smooth feel, {001} cleavage completely split into thin slices, easily, small natural repose angle (35 DEG to 40 DEG), unstable rock, silicification and sliding magnesite, magnesite, petrochemical ore or dolomitic marble, except for a few moderately stable, generally unstable, joints and fissures, physical and mechanical properties of the ore and surrounding rock in mining process is great.
