Talc ufa ndi chinthu chamakampani.Ndi magnesium silicate mineral talc group talc.Chigawo chachikulu ndi amadzimadzi magnesium silicate.Pambuyo kuphwanya, amathandizidwa ndi hydrochloric acid, otsukidwa ndi madzi ndikuwumitsa.
Talc ufa uli ndi zinthu zabwino kwambiri zakuthupi ndi zamankhwala monga mafuta, kukana moto, kukana kwa asidi, kutchinjiriza, malo osungunuka kwambiri, chemistry yosagwira ntchito, mphamvu yophimba bwino, kufewa, kunyezimira kwabwino komanso kutsatsa mwamphamvu.
Talc ufa nthawi zambiri amagwiritsidwa ntchito ngati zodzaza pulasitiki ndi zinthu zamapepala, zodzaza mphira ndi anti adhesion agent wa zinthu za rabara, utoto wapamwamba kwambiri, ndi zina zambiri.

Talc ili ndi zinthu zabwino kwambiri zakuthupi komanso zamankhwala monga lubricity, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, inactive chemical properties, good covering power, softness, good luster, and adsorption strong.Chifukwa cha mawonekedwe ake a kristalo wosanjikiza, talc imakhala ndi chizolowezi chogawanika kukhala masikelo ndi mafuta apadera.Ngati zomwe zili mu Fe2O3 ndizokwera, zidzachepetsa kutchinjiriza kwake.
