Gasi watsopano wokonda zachilengedwe Perfluoroisobutyronitrile C4F7N atha kulowa m'malo mwa sulfure hexafluoride SF6

Pakadali pano, ma media ambiri a GIL amagwiritsa ntchitoSF6 gasi, koma mpweya wa SF6 uli ndi mphamvu yotentha ya dziko (global warming coefficient GWP ndi 23800), imakhudza kwambiri chilengedwe, ndipo imalembedwa ngati mpweya wowonjezera kutentha padziko lonse lapansi. M'zaka zaposachedwa, malo otentha apanyumba ndi akunja amayang'ana kwambiri kafukufuku waSF6mpweya wina, monga kugwiritsa ntchito mpweya wothinikizidwa, SF6 gasi wosakanizidwa, ndi mpweya watsopano wokonda zachilengedwe monga C4F7N, c-C4F8, CF3I, ndi chitukuko cha GIL yosamalira zachilengedwe kuti ipititse patsogolo ubwino wa chilengedwe cha zipangizo. Komabe, ukadaulo wa GIL wokonda zachilengedwe ukadali wakhanda. Kugwiritsa ntchitoSF6 gasi wosakanikiranakapena gasi wopanda chilengedwe wopanda SF6, kupanga zida zamagetsi okwera kwambiri, komanso kukweza gasi wosawononga chilengedwe pazida zamagetsi ndi matekinoloje ena onse amafuna kufufuza mozama ndi kafukufuku.

Perfluoroisobutyronitrile, yomwe imadziwikanso kuti heptafluoroisobutyronitrile, ili ndi mankhwala a mankhwalaC4F7Nndipo ndi organic pawiri. Perfluoroisobutyronitrile ili ndi ubwino wokhala ndi kukhazikika kwa mankhwala, kukana kutentha pang'ono, kuteteza chilengedwe chobiriwira, malo osungunuka kwambiri, osasunthika otsika, komanso kutsekemera kwabwino. Monga insulating sing'anga ya zida zamagetsi, ili ndi chiyembekezo chachikulu chogwiritsa ntchito pamakina amagetsi.

M'tsogolomu, ndi kupititsa patsogolo ntchito yomanga UHV m'dziko langa, chitukuko cha makampani a perfluoroisobutyronitrile chidzapitirirabe bwino. Pankhani ya mpikisano wamsika, makampani aku China ali ndi kuthekera kopanga zochulukaperfluoroisobutyronitrile. M'tsogolomu, ndi kupita patsogolo kwa teknoloji ndi kupititsa patsogolo kopitilira muyeso kwa mafakitale, gawo la msika la zinthu zamtengo wapatali lidzapitirira kuwonjezeka.
