Tetrafluoride ya Kaboni (CF4)

Magawo aukadaulo

Carbon tetrafluoride ndi halogenated hydrocarbon yokhala ndi formula ya mankhwala CF4. Ikhoza kuonedwa ngati halogenated hydrocarbon, halogenated methane, perfluorocarbon, kapena ngati chinthu chosapangidwa ndi zinthu zachilengedwe. Carbon tetrafluoride ndi mpweya wopanda mtundu komanso wopanda fungo, wosasungunuka m'madzi, wosungunuka mu benzene ndi chloroform. Wokhazikika pansi pa kutentha kwabwinobwino ndi kupanikizika, pewani ma oxidant amphamvu, zinthu zomwe zimatha kuyaka kapena kuyaka. Mpweya wosayaka, kuthamanga kwamkati kwa chidebe kumawonjezeka pamene chikuwonetsedwa ndi kutentha kwakukulu, ndipo pali chiopsezo cha kusweka ndi kuphulika. Ndi wokhazikika pa mankhwala ndipo sungayake. Chotsukira cha ammonia-sodium metal chokha chomwe chingagwire ntchito kutentha kwa chipinda. Carbon tetrafluoride ndi mpweya womwe umayambitsa kutentha kwa dziko. Ndi wokhazikika kwambiri, ukhoza kukhala mumlengalenga kwa nthawi yayitali, ndipo ndi mpweya wamphamvu kwambiri wowonjezera kutentha. Carbon tetrafluoride imagwiritsidwa ntchito pochotsa plasma m'mabwalo osiyanasiyana ophatikizika. Imagwiritsidwanso ntchito ngati mpweya wa laser, ndipo imagwiritsidwa ntchito mu mafiriji otsika kutentha, zosungunulira, mafuta odzola, zinthu zotetezera kutentha, ndi zoziziritsira kutentha kwa zida zozindikira infrared. Ndi mpweya wogwiritsidwa ntchito kwambiri mumakampani opanga ma microelectronics. Ndi chisakanizo cha mpweya woyera kwambiri wa tetrafluoromethane ndi mpweya woyera kwambiri wa tetrafluoromethane ndi mpweya woyera kwambiri wa tetrafluoromethane. Ingagwiritsidwe ntchito kwambiri mu silicon, silicon dioxide, silicon nitride, ndi galasi la phosphosilicate. Kudula kwa zinthu zopyapyala monga tungsten ndi tungsten kumagwiritsidwanso ntchito kwambiri pakuyeretsa pamwamba pa zipangizo zamagetsi, kupanga maselo a dzuwa, ukadaulo wa laser, kuzizira kotsika kutentha, kuyang'anira kutuluka kwa madzi, ndi sopo popanga ma circuit osindikizidwa. Imagwiritsidwa ntchito ngati ukadaulo wozizira wotentha komanso ukadaulo wouma wa plasma pama circuit ophatikizidwa. Zochenjeza zosungira: Sungani m'nyumba yosungiramo gasi yozizira, yopuma mpweya yosayaka. Sungani kutali ndi moto ndi magwero otentha. Kutentha kosungirako sikuyenera kupitirira 30°C. Iyenera kusungidwa padera ndi zinthu zoyaka mosavuta (zoyaka) ndi zinthu zowononga ma oxidants, ndipo pewani kusungiramo zinthu zosiyanasiyana. Malo osungiramo zinthu ayenera kukhala ndi zipangizo zochizira zadzidzidzi zomwe zimatuluka madzi.

Ntchito:

① Chosungiramo zinthu mufiriji:

Tetrafluoromethane nthawi zina imagwiritsidwa ntchito ngati choziziritsira kutentha kochepa.

② Kudula:

Amagwiritsidwa ntchito mu microfabrication yamagetsi yokha kapena kuphatikiza ndi mpweya ngati plasma etchant ya silicon, silicon dioxide, ndi silicon nitride.

Phukusi lachizolowezi:

Ubwino:

①Kuyera kwambiri, malo atsopano;

②Wopanga satifiketi ya ISO;

③Kutumiza mwachangu;

④ Njira yowunikira pa intaneti yowongolera khalidwe pa sitepe iliyonse;

⑤Kufunika kwakukulu komanso njira yosamala yogwiritsira ntchito silinda musanadzaze;
