CAS: 7440-44-0
EINECS: 231-153-3
Mpweya ndi chinthu chopanda zitsulo mu gulu la IVA la tebulo lachiwiri la bai.Chilatini cha Carbonium, kutanthauza "malasha, makala".Mawu achi China akuti "carbon" amapangidwa ndi makala "carbon" ndi mawu amwala, kuchokera ku "carbon" phokoso.Mpweya ndi chinthu chofala kwambiri, chopezeka mosiyanasiyana mu gasi wamkulu wa Chemicalbook komanso pansi pa dziko lapansi.Mpweya wakhala ukudziwika ndi kugwiritsidwa ntchito, ndipo mitundu yambiri ya carbon, organics, ndi yofunika kwambiri pa moyo.Mpweya ndi gawo lachitsulo cha nkhumba, chitsulo chopangidwa ndi chitsulo.Mpweya ndi molekyulu yofunikira pazachilengedwe komanso pazamalonda yomwe imamangiriza yokha kuti ipange zinthu zambiri.Mamolekyu ambiri m’zamoyo amakhala ndi carbon.
Mankhwala katundu
Black powdery kapena granular porous makhiristo.Malo otentha 4827 ℃, 3652 ℃ sublimation, kachulukidwe wachibale pafupifupi 1.8-2.1, kachulukidwe wachibale wa 0.08-0.45.
ntchito
(1) kuyeretsedwa kwa mpweya, monga kugwiritsa ntchito mpweya wotsekemera kuti mubwezeretse zosungunulira kuchokera ku mpweya wokhala ndi nthunzi yosungunulira;Kugwiritsa ntchito activated carbon filtration njira yochotsera fungo la mpweya;Kapena amagwiritsidwa ntchito mu masks a gasi ndi ma respirators a mafakitale kuti ateteze ku zinthu zapoizoni.
(2) Kulekanitsa gasi, monga kuchira kwa benzene kuchokera ku gasi wamzinda, petulo, propane ndi kuchira kwa butane kuchokera ku gasi wachilengedwe, zomwe zimagwiritsidwa ntchito pochiza gasi wonyansa mu kaphatikizidwe ka fischer-tropsch, kuti apezenso ma hydrocarbon.(3) madzi gawo adsorption monga mu makampani shuga ndi Chemicalbook adamulowetsa mpweya adsorption njira decolorize shuga madzi, mu makampani adamulowetsa mpweya kuti decolorize zinthu organic, ndi adamulowetsa mpweya kuyeretsedwa organic zosafunika organic mu kusamba electroplating, kuonetsetsa khalidwe la electroplating pamwamba kapena ntchito madzi oipa dephenolization.
(4).Catalysts kapena zonyamulira chothandizira monga chothandizira ntchito mafakitale gasi desulfurization ndi phosgene kupanga, etc. Choncho, adamulowetsa mpweya chimagwiritsidwa ntchito shuga, processing mowa, kuyenga mafuta, mankhwala, reagent, golide, kuyeretsa madzi, kuteteza chilengedwe, kuchira zosungunulira ndi mpweya ndi zina zotero.
