Chigawo chachikulu cha talc ndi hydrotalcite hydrous magnesium silicate ndi formula ya molecular ya mg3 [si4o10] (OH) 2. Talc ndi ya monoclinic system.Krustalo ndi pseudohexagonal kapena rhombic, nthawi zina.Nthawi zambiri zimakhala zazikulu, zamasamba, zozungulira komanso zophatikizika za fibrous.Ndi yopanda mtundu komanso yowonekera kapena yoyera, koma ndi yobiriwira, yachikasu, yofiirira kapena ngakhale yofiira chifukwa cha zonyansa zochepa;cleavage pamwamba ndi ngale.Kulimba 1, mphamvu yokoka yeniyeni 2.7-2.8.

Ufa wa talc uli ndi zinthu zabwino kwambiri zakuthupi komanso zamankhwala monga mafuta, kukana moto, kukana kwa asidi, kutchinjiriza, malo osungunuka kwambiri, kusagwira ntchito kwamankhwala, mphamvu yophimba bwino, kufewa, kuwala kwabwino, kutsatsa kolimba, ndi zina zambiri chifukwa mawonekedwe a kristalo a talc ndi wosanjikiza imakhala ndi chizolowezi chogawanika mosavuta kukhala masikelo ndi mafuta apadera.Ngati zomwe zili mu Fe2O3 ndizokwera kwambiri, kutsekemera kwake kumachepetsedwa.

Kugwiritsa ntchito talc:

(1) Zodzola kalasi (Hz): ntchito mitundu yonse ya ufa moisturizing, kukongola ufa, talcum ufa, etc.

(2) Gulu lazakudya zamankhwala (YS): piritsi lamankhwala, zokutira shuga, ufa wa prickly kutentha, mankhwala aku China, zowonjezera chakudya, wodzipatula, ndi zina.

(3) Kupaka kalasi (TL): amagwiritsidwa ntchito popanga pigment yoyera ndi mitundu yonse yamadzi, opangira mafuta, zokutira zamafakitale a resin, primer, utoto woteteza, etc.

(4) Paper giredi (zz): amagwiritsidwa ntchito ngati zodzaza mitundu yonse ya mapepala ndi mapepala, matabwa owongolera phula.

(5) Pulasitiki kalasi (SL): ntchito monga filler kwa polypropylene, nayiloni, polyvinyl kolorayidi, polyethylene, polystyrene, poliyesitala ndi mapulasitiki ena.

(6) Rubber giredi (AJ): yogwiritsidwa ntchito ngati mphira filler ndi anti adhesion agent wa zinthu mphira.
