Mpweya wa Tetrafluoride (CF4)

Technical Parameters

Mpweya wa tetrafluoride ndi halogenated hydrocarbon yokhala ndi chilinganizo chamankhwala CF4. Itha kuwonedwa ngati halogenated hydrocarbon, halogenated methane, perfluorocarbon, kapena ngati pawiri. Carbon tetrafluoride ndi mpweya wopanda mtundu komanso wopanda fungo, wosasungunuka m'madzi, wosungunuka mu benzene ndi chloroform. Wokhazikika pansi pa kutentha kwabwino ndi kupanikizika, pewani ma okosijeni amphamvu, zinthu zoyaka kapena zoyaka. Mpweya wosayaka, kupanikizika kwa mkati mwa chidebecho kumawonjezeka pamene kutentha kwakukulu, ndipo pali ngozi yophulika ndi kuphulika. Ndiwokhazikika pamankhwala komanso osayaka. Only madzi ammonia-sodium zitsulo reagent akhoza kugwira ntchito firiji. Mpweya wa tetrafluoride ndi mpweya womwe umayambitsa kutentha kwa thupi. Ndiwokhazikika kwambiri, imatha kukhala mumlengalenga kwa nthawi yayitali, ndipo ndi mpweya wamphamvu kwambiri wowonjezera kutentha. Mpweya wa tetrafluoride umagwiritsidwa ntchito mu plasma etching process ya mabwalo osiyanasiyana ophatikizika. Amagwiritsidwanso ntchito ngati mpweya wa laser, ndipo amagwiritsidwa ntchito mufiriji, zosungunulira, zothira mafuta, zoziziritsa kukhosi, ndi zoziziritsa kukhosi za infrared detectors. Ndiwo omwe amagwiritsidwa ntchito kwambiri ndi plasma etching gasi mumakampani a microelectronics. Ndi chisakanizo cha mpweya wa tetrafluoromethane woyeretsedwa kwambiri ndi mpweya wa tetrafluoromethane woyeretsa kwambiri komanso mpweya wabwino kwambiri. Itha kugwiritsidwa ntchito kwambiri mu silicon, silicon dioxide, silicon nitride, ndi galasi la phosphosilicate. Kuyika kwazinthu zamakanema opyapyala monga tungsten ndi tungsten kumagwiritsidwanso ntchito kwambiri pakuyeretsa pazida zamagetsi, kupanga ma cell a solar, ukadaulo wa laser, firiji yotsika kutentha, kuyang'anira kutayikira, ndi zotsukira pakupanga madera osindikizidwa. Amagwiritsidwa ntchito ngati refrigerant yotsika kutentha komanso ukadaulo wa plasma wowuma wowongolera mabwalo ophatikizika. Kusamala posungirako: Sungani m'nyumba yosungiramo mpweya yozizirira komanso yosapsa. Khalani kutali ndi gwero la moto ndi kutentha. Kutentha kosungirako sikuyenera kupitirira 30°C. Iyenera kusungidwa mosiyana ndi zosavuta zoyaka (zoyaka) ndi zowonjezera zowonjezera, ndipo pewani kusungirako kosakanikirana. Malo osungiramo zinthu ayenera kukhala ndi zida zothandizira zadzidzidzi zomwe zatuluka.

Ntchito:

① Refrigerant:

Tetrafluoromethane nthawi zina amagwiritsidwa ntchito ngati firiji yotsika kutentha.

② Kujambula:

Amagwiritsidwa ntchito pamagetsi a microfabrication okha kapena kuphatikiza ndi okosijeni ngati plasma etchant ya silicon, silicon dioxide, ndi silicon nitride.

Phukusi labwinobwino:

Ubwino:

①Kuyera kwakukulu, malo aposachedwa;

② ISO wopanga satifiketi;

③Kutumiza mwachangu;

④Dongosolo lowunikira pa intaneti pakuwongolera kwamtundu uliwonse;

⑤Kufunika kwakukulu ndi njira yosamala yogwiritsira ntchito silinda musanadzaze;
