Kabhoni Tetrafluoride (CF4)

Magadzirirwo ehunyanzvi

Carbon tetrafluoride ihalogenated hydrocarbon ine fomura yemakemikari CF4. Inogona kuonekwa sehalogenated hydrocarbon, halogenated methane, perfluorocarbon, kana sechinhu chisina kuumbwa. Carbon tetrafluoride igesi isina ruvara uye isina hwema, hainyungudike mumvura, inonyungudika mubenzene nechloroform. Yakagadzikana pasi pekupisa kwakajairika uye kumanikidzwa, dzivisa maoxydants akasimba, zvinhu zvinobvira kana zvinopisa. Gasi risingatsve, kumanikidzwa kwemukati memudziyo kuchawedzera kana kuchipisa zvakanyanya, uye pane njodzi yekutsemuka nekuputika. Yakasimba pamakemikari uye haitsve. Chinongoshanda chete pakupisa kwemukamuri. Carbon tetrafluoride igesi inokonzera greenhouse effect. Yakasimba kwazvo, inogona kugara mumhepo kwenguva yakareba, uye igesi ine simba kwazvo yegreenhouse. Carbon tetrafluoride inoshandiswa mukuita kweplasma etching yematunhu akasiyana-siyana akabatanidzwa. Inoshandiswawo segasi relaser, uye inoshandiswa mumafiriji, zvinonyungudutsa, mafuta, zvinhu zvinodzivirira kupisa, uye zvinotonhodza zve infrared detectors. Ndiyo gasi rinoshandiswa zvakanyanya muindasitiri ye microelectronics. Imusanganiswa wegasi re tetrafluoromethane high-purity uye gasi re tetrafluoromethane high-purity uye oxygen yakawanda-purity. Inogona kushandiswa zvakanyanya mu silicon, silicon dioxide, silicon nitride, uye phosphosilicate glass. Kucheka kwezvinhu zvakatetepa zvakaita se tungsten ne tungsten kunoshandiswawo zvakanyanya mukuchenesa pamusoro pemidziyo yemagetsi, kugadzira solar cell, laser technology, kutonhora kwekupisa kushoma, kuongorora kubuda kwemvura, uye detergent mukugadzirwa kwema circuit akadhindwa. Inoshandiswa se refrigerant yekupisa kushoma uye plasma dry etching tekinoroji yema circuit akabatanidzwa. Kuchenjerera pakuchengetedza: Chengeta munzvimbo inotonhorera, ine mhepo isingatsve. Chengeta kure nemoto nekupisa. Tembiricha yekuchengetera haifanirwe kudarika 30°C. Inofanira kuchengetwa yakasiyana nezvinhu zvinobvira zviri nyore (zvinobvira) uye zvinooxidative, uye dzivisa kuchengetwa kwakasiyana-siyana. Nzvimbo yekuchengetera inofanira kunge ine michina yekurapa nekukurumidzira inobuda.

Kushandiswa:

① Refrigerant:

Dzimwe nguva tetrafluoromethane inoshandiswa semuchina wekuisa mufiriji patembiricha yakaderera.

② Kucheka:

Inoshandiswa mukugadzirwa kwezvinhu zvemagetsi chete kana pamwe chete neokisijeni sechikamu cheplasma chesilicon, silicon dioxide, uye silicon nitride.

Pakeji yakajairika:

Zvakanakira:

①Kuchena kwakanyanya, nzvimbo itsva;

②Mugadziri wezvitupa zveISO;

③Kutumira nekukurumidza;

④Sisitimu yekuongorora yepamhepo yekudzora mhando padanho rega rega;

⑤Kushandiswa kwakawanda uye kwakanyatsorongwa kwekubata silinda usati wazadza;
