Igesi entsha enobuhlobo nokusingqongileyo iPerfluoroisobutyronitrile C4F7N ingathatha indawo yesulfure hexafluoride SF6

Okwangoku, uninzi lwezixhobo zokukhusela i-GIL zisetyenziswaIgesi ye-SF6, kodwa igesi ye-SF6 inefuthe elinamandla kwi-greenhouse (i-coefficient yokufudumala kwehlabathi i-GWP yi-23800), inempembelelo enkulu kwindalo esingqongileyo, kwaye idweliswe njengegesi ye-greenhouse ethintelweyo kwihlabathi liphela. Kwiminyaka yakutshanje, iindawo ezishushu zasekhaya nezangaphandle ziye zagxila kuphando lweSF6iigesi ezizezinye, ezinje ngokusetyenziswa komoya ocinezelweyo, igesi exutyiweyo ye-SF6, kunye neegesi ezintsha ezinobuhlobo nokusingqongileyo ezifana ne-C4F7N, c-C4F8, CF3I, kunye nophuhliso lwe-GIL enobuhlobo nokusingqongileyo ukuphucula izibonelelo zokusingqongileyo zezixhobo. Nangona kunjalo, itekhnoloji ye-GIL enobuhlobo nokusingqongileyo isesencinci. Ukusetyenziswa kweIgesi exutyiweyo ye-SF6okanye igesi enobuhlobo nokusingqongileyo engena-SF6 ngokupheleleyo, uphuhliso lwezixhobo ezinombane ophezulu, kunye nokukhuthazwa kwegesi enobuhlobo nokusingqongileyo kwizixhobo zombane nakwezinye iiteknoloji zonke zifuna uphando olunzulu kunye nophando.

I-Perfluoroisobutyronitrile, ekwaziwa ngokuba yi-heptafluoroisobutyronitrile, inefomyula yeekhemikhaliC4F7Nkwaye yi-organic compound. I-Perfluoroisobutyronitrile ineenzuzo zokuba nozinzo oluhle lweekhemikhali, ukumelana nobushushu obuphantsi, ukhuseleko oluluhlaza kokusingqongileyo, indawo yokunyibilika ephezulu, ukuguquguquka okuphantsi, kunye nobushushu obuhle. Njengesixhobo sokukhusela izixhobo zombane, inamathuba amaninzi okusetyenziswa kwicandelo leenkqubo zamandla.

Kwixesha elizayo, ngokukhawuleziswa kokwakhiwa kweeprojekthi ze-UHV kwilizwe lam, impumelelo yeshishini le-perfluoroisobutyronitrile iya kuqhubeka iphucuka. Ngokuphathelele ukhuphiswano lwemarike, iinkampani zaseTshayina zinamandla okuvelisa ngobuninzi.i-perfluoroisobutyronitrileKwixesha elizayo, ngenxa yokuqhubela phambili kwetekhnoloji kunye nokuphuculwa okuqhubekayo kwemigangatho yoshishino, isabelo semarike seemveliso ezikumgangatho ophezulu siya kuqhubeka sikhula.
