EPTlc powEPTfor EPT Paper grade talc powder
EPTlcum Powder is a special all-natural mineral create by way of verification amp wonderful grinding. This item may be used in Paints, Cosmetic, Paper, Pharmaceuticals, FerEPTzers and so forth.
EPTlc lubricity, fire resistance, acid resistance, insulation, substantial melting point, chemical inertness, good masking EPT and comfortable, great gloss, strong adsorption capability, superb bodily and chemical qualities, the crystal composition of talc is a layer, so it is easy to spEPT into flake development and EPT lubrication and if the Fe2O3 material is really higher will decrease its insulation.
The primary 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, sometimes. Typically dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a modest quantity of impurities and has ligEPT green, ligEPT yellow, ligEPT brown or pale crimson the cleavage aircraft is Pearl luster. Hardness one, distinct gravity 2.seven ~ 2.8.
Actual physical Examination:
Color is snow white
Luster is uninteresting to pearly or greasy
Transparency crystals are translucent and masses are opaque
Crystal method is mono-clinic two/m
Hardness is one.
Certain Gravity is two.seven – 2.eight
