Igesi entsha ehambisana nemvelo i-Perfluoroisobutyronitrile C4F7N ingase ithathele indawo i-sulphur hexafluoride SF6

Njengamanje, iningi le-GIL insulation media media lisetshenziswaSF6 igesi, kodwa igesi ye-SF6 inomphumela onamandla we-greenhouse (i-global warming coefficient GWP ingu-23800), inomthelela omkhulu emvelweni, futhi isohlwini lwegesi ebamba ukushisa ekhawulelwe emazweni ngamazwe. Eminyakeni yakamuva, izindawo ezishisayo zasekhaya nezangaphandle zigxile ocwaningweni lweSF6amagesi ahlukile, afana nokusetshenziswa komoya ocindezelweyo, igesi exubile ye-SF6, namagesi amasha ahambisana nemvelo afana ne-C4F7N, c-C4F8, CF3I, kanye nokuthuthukiswa kwe-GIL ehambisana nemvelo ukuze kuthuthukiswe izinzuzo zemvelo zemishini. Kodwa-ke, ubuchwepheshe be-GIL obunobungani bemvelo busaqala. Ukusetshenziswa kweSF6 igesi exubilenoma igesi ehambisana ngokuphelele nemvelo eyi-SF6, ukuthuthukiswa kwemishini enamandla kagesi, kanye nokukhuthazwa kwegesi evikela imvelo ezintweni zikagesi nobunye ubuchwepheshe konke kudinga ukuhlola nokucwaninga okujulile.

I-Perfluoroisobutyronitrile, eyaziwa nangokuthi i-heptafluoroisobutyronitrile, inefomula yamakhemikhali yeC4F7Nfuthi iyinhlanganisela yezinto eziphilayo. I-Perfluoroisobutyronitrile inezinzuzo zokuzinza okuhle kwamakhemikhali, ukumelana nokushisa okuphansi, ukuvikelwa kwemvelo okuluhlaza, indawo encibilikayo ephezulu, ukuguquguquka okuphansi, nokufakwa kahle. Njengendawo yokuvikela impahla kagesi, inamathuba amaningi okusebenza emkhakheni wezinhlelo zamandla.

Esikhathini esizayo, ngokusheshisa ukwakhiwa kwamaphrojekthi we-UHV ezweni lami, ukuchuma kwemboni ye-perfluoroisobutyronitrile kuzoqhubeka nokuba ngcono. Mayelana nokuncintisana kwemakethe, izinkampani zaseShayina zinamandla okukhiqiza ngobuningii-perfluoroisobutyronitrile. Ngokuzayo, ngokuthuthuka kobuchwepheshe kanye nokwenza ngcono okuqhubekayo kwamazinga emboni, isabelo semakethe semikhiqizo yekhwalithi ephezulu sizoqhubeka nokukhula.
