Tshiab ib puag ncig tus phooj ywg roj Perfluoroisobutyronitrile C4F7N tuaj yeem hloov sulfur hexafluoride SF6

Tam sim no, feem ntau GIL rwb thaiv tsev media sivSF 6 gas, tab sis SF6 roj muaj cov nyhuv tsev cog khoom muaj zog (lub ntiaj teb ua kom sov coefficient GWP yog 23800), muaj kev cuam tshuam zoo rau ib puag ncig, thiab tau teev tseg raws li txwv tsis pub tsev cog khoom roj thoob ntiaj teb. Nyob rau hauv xyoo tas los no, domestic thiab txawv teb chaws hotspots tau tsom mus rau kev tshawb fawb ntawmSF 6lwm cov pa roj, xws li kev siv cov cua compressed, SF6 sib xyaw roj, thiab cov pa roj carbon monoxide tshiab xws li C4F7N, c-C4F8, CF3I, thiab kev txhim kho ib puag ncig tus phooj ywg GIL los txhim kho cov txiaj ntsig ib puag ncig ntawm cov khoom siv. Txawm li cas los xij, ib puag ncig tus phooj ywg GIL thev naus laus zis tseem nyob hauv nws cov me nyuam mos. Kev siv ntawmSF6 sib xyaw gaslos yog tag nrho SF6-dawb ib puag ncig tus phooj ywg roj, kev txhim kho cov khoom siv hluav taws xob siab, thiab kev txhawb nqa ntawm ib puag ncig tus phooj ywg roj hauv cov khoom siv hluav taws xob thiab lwm yam thev naus laus zis txhua qhov xav tau kev tshawb nrhiav thiab kev tshawb fawb tob.

Perfluoroisobutyronitrile, tseem hu ua heptafluoroisobutyronitrile, muaj cov tshuaj formula ntawmC4F7 Nthiab yog ib qho organic compound. Perfluoroisobutyronitrile muaj qhov zoo ntawm cov tshuaj zoo stability, tsis kub tsis kam, ntsuab ib puag ncig tiv thaiv, siab melting point, tsis tshua muaj volatility, thiab zoo rwb thaiv tsev. Raws li qhov nruab nrab insulating rau cov khoom siv hluav taws xob, nws muaj cov ntawv thov dav dav hauv kev siv hluav taws xob.

Nyob rau yav tom ntej, nrog kev nrawm ntawm kev tsim kho UHV cov haujlwm hauv kuv lub tebchaws, kev vam meej ntawm perfluoroisobutyronitrile kev lag luam yuav txhim kho ntxiv mus. Hais txog kev sib tw ua lag luam, Suav tuam txhab muaj peev xwm los tsim cov khoom lojperfluoroisobutyronitrile. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm kev siv tshuab thiab kev txhim kho txuas ntxiv ntawm cov qauv kev lag luam, kev ua lag luam feem ntau ntawm cov khoom zoo yuav nce ntxiv.
