CAS No. 7803-51-2 Phosphine Supplier. Makhalidwe a Phosphine

Phosphine (PH₃) ndi mpweya wopanda mtundu, woyaka komanso fungo la nsomba lomwe ndi loopsa kwambiri kwa anthu. Ndi mankhwala ofanana ndi ammonia (NH₃), koma ndi ochepa komanso ochita chidwi kwambiri. Phosphine amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza mafakitale a semiconductor a doping silicon ndi gallium arsenide, popanga zitsulo za phosphides, komanso ngati fumigant paulimi.

Nazi zina zazikulu za phosphine:

Katundu Wathupi:
Phosphine ndi mpweya wopanda mtundu womwe umatentha kutentha komanso kupanikizika.
Imayaka ndipo imatha kuyaka yokha ikakumana ndi mpweya chifukwa chakuchitanso kwambiri.
Kawopsedwe:
Phosphine ndi poizoni kwambiri pokoka mpweya, zomwe zimawononga kwambiri mapapo ndipo zimatha kupha.
Zimakhalanso zapoizoni ngati zitamezedwa kapena kutengeka pakhungu.
Zogwiritsa:
Mu kupanga semiconductor kwa njira za doping.
Monga fumigant mu yosungirako tirigu kulamulira tizirombo.
Mu synthesis wa organophosphorus mankhwala.
Kugwira ndi Kusunga:
Phosphine iyenera kugwiridwa mosamala kwambiri chifukwa cha kawopsedwe komanso kuyaka kwake.
Iyenera kusungidwa pamalo ozizira, ouma kutali ndi gwero lililonse la kuyatsa.
Kusamala kwapadera ndikofunikira kuti mupewe kutayikira kapena kutayikira.
Shanghai Wechem Chemical Co., Ltd. ili ndi zida zapamwamba komanso ukadaulo wowunikira mu labotale yake, kuwonetsetsa kuti titha kuwongolera ndikuyesa kwamtundu wazinthu. Timatsatira dongosolo lokhazikika la kasamalidwe ka khalidwe, kuyang'anira ndi kuyang'anira sitepe iliyonse kuchokera pa kugula zinthu mpaka kupanga kuti titsimikizire kuti zomwe timapereka zimakwaniritsa miyezo yapamwamba kwambiri. Ngati mukufuna mankhwalawa, chonde omasuka kulankhula nafe nthawi iliyonse!
