Upfu hweTalc chigadzirwa chemaindasitiri, chiri muboka retalc remaminerari emagnesium silicate. Chikamu chayo chikuru i hydrated magnesium silicate, iyo inopwanywa, yorapwa ne hydrochloric acid, yogezwa nemvura, yoomeswa. Chikamu chikuru chetalc i magnesium silicate ine mvura, ine molecular formula yeMg3 [Si4O10] (OH) 2; Talc ndeye monoclinic crystal system. Makristasi ari muchimiro chepseudo hexagonal kana rhombic flakes, dzimwe nguva anoonekwa. Anowanzo umbwa kuita ma clumps akaomarara, akafanana nemashizha, radial, uye fibrous aggregates. Isina ruvara runopenya kana kuti chena, asi inoita kunge girini rakapfava, yero rakapfava, brown rakapfava, kana kuti tsvuku rakapfava nekuda kwekuvapo kwetsvina diki; Nzvimbo yakatsemuka ine pearl luster. Kuoma 1, gravity chaiyo 2.7-2.8

Maitiro ekugadzira:

Talc inobviswa (chinhu chisina kugadzirwa cheupfu hwetalc) inogona kupwanywa zvakananga neRaymond mill kana mamwe magayo ane simba guru mushure mekusarudza talc yakanaka, uye kurongedzwa mumabhegi akarukwa (50kg, kana 25kg mabhegi akarukwa) isati yatengeswa sezvigadzirwa zvakapedzwa. Panyaya yekuchera, nekuda kwematombo asina kugadzikana zvakanyanya uye dombo rakatenderedza, muviri wematombo akawanda wakakombama uye wakakombama uye wakakora zvakanyanya. Chimiro neukobvu hwemuviri wematombo zvakasiyana zvikuru, uye kune matombo akawanda akasanganiswa mumuviri wematombo. Kare, nzira yekuchera yakatambanudzwa yaishandiswa (mimwe migodhi ichiri kushandisa nzira iyi).

Hunhu:

Ine hunhu hwakanaka hwemuviri nemakemikari akadai sekunyorovesa, kuramba moto, kuramba acid, kuputira, kunyunguduka kwakanyanya, hunhu hwemakemikari husina basa, simba rakanaka rekufukidza, kupfava, kupenya kwakanaka, uye kunyunguduka kwakasimba. Nekuda kwechimiro chekristaro chetalc, ine katsika kekupatsanurana kuita zviyero uye kunyorovesa kwakakosha.

Kushandiswa：

Giredhi rezvizoro (HZ): rinoshandiswa pamhando dzakasiyana dzehupfu hunonyorovesa, hupfu hwerunako, hupfu hwemuviri, nezvimwewo.

Giredhi rekuputira (TL): Rinoshandiswa pakugadzira pigment chena uye mapurasitiki akasiyana-siyana akagadzirwa nemvura, akagadzirwa nemafuta, resin, ma primer, pendi dzinodzivirira, nezvimwewo.

Giredhi repepa (ZZ): Rinoshandiswa sechinozadza mhando dzakasiyana dzepepa nebhodhi, sechinodzorwa neasphalt yehuni.

Giredhi repurasitiki (SL): Rinoshandiswa sechinozadza mapurasitiki akadai sepolypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene, uye polyester.

Rubber grade (AJ): inoshandiswa pakuzadza rabha uye anti-glue agents muzvigadzirwa zverabha.

Chiyero chetambo (DL): chinoshandiswa pakuwedzera tambo dzerabha uye zvinosanganisa tambo.

Giredhi reCeramic (TC): rinoshandiswa kugadzira zviumbwa zvemagetsi, zviumbwa zvemagetsi zvisina waya, zviumbwa zvemaindasitiri zvakasiyana-siyana, zviumbwa zvekuvaka, zviumbwa zvemazuva ese, uye enamel.
