Hexafluoride Whāwhā
Hexafluoride WhāwhāHe hau kore-waro, kāore he tae, kāore he kakara, ā, kāore e mura te (SF6). Ko te whakamahinga matua o te SF6 kei roto i te umanga hiko hei reo hiko hau mō ngā momo whati hiko hiko, taputapu whakawhiti me ētahi atu taputapu hiko, he maha ngā wā ka whakakapi i ngā whati hiko hinu (OCB) ka taea te pupuri i ngā PCB kino. Ka whakamahia te hau SF6 i raro i te pēhanga hei ārai i roto i ngā taputapu whakawhiti hau (GIS) nā te mea he nui ake tōna kaha hiko i te hau, i te hauota maroke rānei. Mā tēnei āhuatanga ka taea te whakaiti i te rahi o te taputapu hiko.

Kei te wātea te whanariki hexafluoride (SF6) i roto i ngā rango me ngā tāke pahu. E whakamahia ana i roto i ētahi ahumahi tae atu ki:
1) Mana me te Pūngao: E whakamahia ana hei ārai i te whānuitanga o ngā taputapu hiko me ngā taputapu hiko ngaohiko teitei pērā i ngā whati ara iahiko, ngā taputapu pana me ngā whakatere matūriki.
2) Karāhe: Ngā matapihi ārai – ka whakaitihia te tuku oro me te whakawhiti wera.
3) Rino me ngā Konganuku: I roto i te hanga me te purenga o te konupūmā me te konumohe rewa.
4) Hikohiko: He hexafluoride whanariki parakore teitei e whakamahia ana i roto i ngā tono hikohiko me ngā tono haurua-ā-ira.
