EPTlcum powder/talc powEPTlow price for EPT Use
EPTlcum Powder is a distinctive normal mineral produce by way of verification amp wonderful grinding. This product might be utilized in Paints, Cosmetic, Paper, Pharmaceuticals, FerEPTzers and many others.
EPTlc lubricity, hearth resistance, acid resistance, insulation, higher melting point, chemical inertness, great covering EPT and soft, very good gloss, strong adsorption capacity, superb bodily and chemical qualities, the crystal framework of talc is a layer, so it is effortless to spEPT into flake development and EPT lubrication and if the Fe2O3 content is very high will minimize its insulation.
The main element of talc is hydrotalcite conXiHu (West Lake) Dis.Hu (West Lake) Dis. magnesium silicate, and the method is Mg3 [Si4O10] (OH) two. EPTlc beEPTs to monoclinic technique. The crystal is false, six sides or diamond flakes, at times. Usually dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a tiny quantity of impurities and has ligEPT green, ligEPT yellow, ligEPT brown or pale purple the cleavage airplane is Pearl luster. Hardness one, certain gravity 2.7 ~ two.eight.
