Ka taea e te hau hou e pai ana ki te taiao, te Perfluoroisobutyronitrile C4F7N, te whakakapi i te whanariki hexafluoride SF6.

I tēnei wā, ko te nuinga o ngā rauemi whakamahana GIL e whakamahi anaHau SF6, engari he kaha te pānga kati kōtuhi o te hau SF6 (ko te tauwehenga mahana o te ao GWP he 23800), he nui tōna pānga ki te taiao, ā, kua whakarārangihia hei hau kati kōtuhi herea o te ao. I ngā tau tata nei, kua arotahi ngā wāhi wera o roto me tāwāhi ki te rangahau oSF6ngā hau rerekē, pērā i te whakamahinga o te hau kōpeke, te hau whakauru SF6, me ngā hau hou e pai ana ki te taiao pērā i te C4F7N, c-C4F8, CF3I, me te whakawhanaketanga o te GIL e pai ana ki te taiao hei whakapai ake i ngā painga taiao o ngā taputapu. Heoi, kei te tīmatanga tonu te hangarau GIL e pai ana ki te taiao. Ko te whakamahinga oHau whakaranu SF6te hau kore-SF6 e pai ana ki te taiao, te whakawhanaketanga o ngā taputapu ngaohiko teitei, me te whakatairanga i te hau pai ki te taiao i roto i ngā taputapu hiko me ētahi atu hangarau, me rapu hohonu me te rangahau.

Perfluoroisobutyronitrile, e mōhiotia ana ko te heptafluoroisobutyronitrile, ko tōna tauira matū koC4F7Nā, he matū waro hoki. He pai ngā painga o te perfluoroisobutyronitrile, arā, he pumau matū pai, he ātete pāmahana iti, he tiaki taiao matomato, he teitei te ira rewa, he iti te piki me te heke, me te pai o te whakamarumaru. Hei arai mō ngā taputapu hiko, he whānui ngā tono i roto i te mara o ngā pūnaha hiko.

Ā tōna wā, me te tere haere o te hanganga o ngā kaupapa UHV i tōku whenua, ka piki haere tonu te hua o te umanga perfluoroisobutyronitrile. Mō te whakataetae mākete, kei a ngā kamupene Haina te kaha ki te whakaputa papatipu.perfluoroisobutyronitrile. I ngā rā kei te heke mai, me te whanaketanga o te hangarau me te whakapai tonu i ngā paerewa ahumahi, ka piki haere tonu te wāhi mākete o ngā hua kounga teitei.
