CAS Helu 2551-62-4 Sulfur Hexafluoride Mea Hoʻolako. Nā ʻano o ka Sulfur Hexafluoride

ʻO Sulfur hexafluoride (SF6) he kinoea synthetic i loaʻa i nā noi he nui ma nā ʻoihana like ʻole. He 2551-62-4 kona helu CAS. Eia kekahi mau hiʻohiʻona o ka sulfur hexafluoride:

Nā waiwai kemika:
Kumu: SF6
Kaumaha Molekala: Ma kahi o 146.06 g/mol
Lae paila: Ma kahi o −63.8 °C
Lae hehee: Ma kahi o −50.8 °C
Nā waiwai kino:
ʻO SF6 he kinoea kala ʻole, ʻala ʻole, ʻaʻole hiki ke puhi ʻia.
ʻOi aku ke kaumaha ma mua o ka ea, me ka nui o ka ea ma kahi o ʻelima mau manawa ma mua o ke ea ma nā kūlana maʻamau.
ʻAʻole hiki ke hana ma lalo o nā kūlana maʻamau akā hiki ke lilo i mea ʻawaʻawa i nā kiʻekiʻe kiʻekiʻe ma muli o kona hiki ke hoʻoneʻe i ka oxygen a kumu i ka asphyxiation.
Nā Pono Uila:
ʻIke ʻia ʻo SF6 no kona ikaika dielectric ʻokoʻa, e hoʻolilo iā ia i insulator maikaʻi loa i nā mea uila uila kiʻekiʻe e like me nā mea hoʻokele kaapuni, switchgear, a me nā mea hoʻololi.
Ka hopena o ke kaiapuni:
He kinoea hoʻomehana honua ikaika ʻo SF6, me ka hiki ke hoʻomehana honua (GWP) ma luna o 20 mau makahiki ma kahi o 23,500 mau manawa ʻoi aku ma mua o CO2.
Ma muli o ka lōʻihi o ke ola ʻana o ka lewa (i manaʻo ʻia ma kahi o 3,200 mau makahiki), ua hoʻoikaika ʻia e hōʻemi i ka hoʻokuʻu ʻana a loaʻa i nā mea ʻē aʻe inā hiki.
Nā noi:
ʻEnekinia Uila: Hoʻohana ʻia ma ke ʻano he insulating a me ka arc-quenching medium i nā mea hoʻololi uila kiʻekiʻe a me nā mea hoʻokaʻawale kaapuni.
Nā Kiʻi Lapaʻau: Hoʻohana ʻia i ke kiʻi hoʻohālikelike magnetic (MRI) a me nā kiʻi helu helu (CT) ma ke ʻano he mea ʻokoʻa.
Hoʻoheheʻe Metala: Hiki ke hoʻohana ʻia ʻo SF6 i ke kaʻina hoʻoheheʻe e pale i ka hoʻoheheʻe ʻana o nā metala hehee.
ʻenehana Laser: Hoʻohana ʻia ia i kekahi mau ʻano lasers.
Ka lawelawe a me ka palekana:
Pono e mālama ʻia ʻo SF6 me ka mālama pono e pale aku i nā leaka, hiki ke kōkua i ka hoʻokuʻu ʻia ʻana o ke kinoea ʻōmaʻomaʻo.
ʻAʻohe mea ʻawaʻawa ma kona ʻano maʻemaʻe akā hiki ke pōʻino inā e hoʻoheheʻe ʻia i nā huahana ʻona ma lalo o nā kūlana arcing.
Pono nā ʻōnaehana ea a me ka nānā ʻana i ka wā e hana pū ai me SF6 e hōʻoia i ka palekana o ka limahana a me ka palekana o ke kaiapuni.
