EPTlcum powder/talc powEPTlow cost for EPT Use
EPTlcum Powder is a unique all-natural mineral produce through verification amp fine grinding. This solution may be utilized in Paints, Beauty, Paper, Prescribed drugs, FerEPTzers etc.
EPTlc lubricity, hearth resistance, acid resistance, insulation, substantial melting position, chemical inertness, excellent covering EPT and delicate, very good gloss, robust adsorption potential, exceptional actual physical and chemical properties, the crystal composition of talc is a layer, so it is simple to spEPT into flake trend and EPT lubrication and if the Fe2O3 articles is very large will decrease its insulation.
The main component of talc is hydrotalcite conXiHu (West Lake) Dis.Hu (West Lake) Dis. magnesium silicate, and the formulation is Mg3 [Si4O10] (OH) two. EPTlc beEPTs to monoclinic method. The crystal is false, six sides or diamond flakes, occasionally. Generally dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a tiny sum of impurities and has ligEPT environmentally friendly, ligEPT yellow, ligEPT brown or pale red the cleavage airplane is Pearl luster. Hardness one, certain gravity two.7 ~ 2.8.
Actual physical Analysis:
Colour is snow white
Luster is dull to pearly or greasy
Transparency crystals are translucent and masses are opaque
Crystal system is mono-clinic two/m
Hardness is one.
Particular Gravity is 2.7 – 2.eight
