Sulfur Hexafluoride (SF6)

Nā palena kikoʻī

ʻO Sulfur hexafluoride, nona ka haʻina kemikala ʻo SF6, kahi kinoea ʻole, ʻaʻohe ʻaʻala, ʻaʻohe mea ʻawahia, a me nā kinoea kū ʻole kuni ʻole. He gaseous ka sulfur hexafluoride ma lalo o ka mahana maʻamau a me ke kaomi, me nā waiwai kemika paʻa, hiki ke hoʻoheheʻe ʻia i ka wai, ka wai ʻona a me ka ether, hiki ke hoʻoheheʻe ʻia i ka potassium hydroxide, a ʻaʻole ia e hana me ka sodium me ka sodium hydroxide, ka amonia wai a me ka waikawa hydrochloric. ʻAʻole ia e pane me ke keleawe, kālā, hao, a me aluminika i kahi maloʻo ma lalo o 300 ° C. Ma lalo o 500 ℃, ʻaʻohe ona hopena ma ka quartz. Hoʻopili ia me ka sodium metallic ma 250 ° C, a hana i ka amonia wai ma -64 ° C. E popopo ana ke hui ʻia me ka hydrogen sulfide a hoʻomehana ʻia. Ma 200 ℃, i ke alo o kekahi mau metala e like me ke kila a me ka silicon kila, hiki iā ia ke hāpai i kāna decomposition lohi. ʻO Sulfur hexafluoride kahi hanauna hou o nā mea uila uila ultra-high voltage, i hoʻohana ākea ʻia no ka hoʻāhu kinoea o nā uila uila, nā pono uila a me nā nalu radar, a ma ke ʻano he mea insulate no ka pio ʻana o ka piʻo a me nā mea hiki ke hoʻololi i ka uila nui. ʻO nā mea maikaʻi o ka SF6 gas-insulated pipeline transmissions laina he haʻahaʻa lilo dielectric, hiki i ka lawe nui ʻana, a hiki ke hoʻohana ʻia i nā hanana kulu kiʻekiʻe. ʻO ka SF6 gas insulated transformer i nā pono o ke ahi a me ka pale ʻana o ka pahū. Loaʻa i ka sulfur hexafluoride nā ʻano o ke kūpaʻa kemika maikaʻi a me ka ʻole ka hoʻowahāwahā i nā pono hana. Hiki ke hoʻohana ʻia ma ke ʻano he coolant i ka ʻoihana hau (e hana ana ka mahana ma waena o -45 ~ 0 ℃). ʻO ka hechafluoride sulfur he kiʻekiʻe kiʻekiʻe maʻemaʻe kahi etchant uila pono, kahi e hoʻohana ākea ʻia ma ke kahua o ka ʻenehana microelectronics ma ke ʻano he etching plasma a me ka mea hoʻomaʻemaʻe i ka hana ʻana i nā kaapuni hoʻohui nui e like me nā ʻomipili kamepiula a me nā aniani aniani wai. Mālama i ka mālama ʻana: E mālama i kahi waihona hoʻoluʻu a hoʻoliʻiliʻi. E mālama i nā kumu ahi a me nā kumu wela. ʻAʻole iʻoi aku ka nui o ka mahana mālama ma mua o 30 ° C. Pono e mālama kaʻawale ʻia mai nā mea maʻalahi (combustible) a me nā oxidants, a pale i ka mālama hoʻohuihui. Pono e hoʻolako ʻia kahi e waiho ai me nā lako hana hoʻopulapula leakage.

Hoʻohana ʻia ʻo SF6 i ka ʻoihana uila ma ke ʻano he dielectric kinoea no nā mea haki kaapuni uila kiʻekiʻe, switchgear, a me nā pono uila ʻē aʻe, e hoʻololi pinepine i nā mea haki i hoʻopiha ʻia i ka aila (OCB) i hiki ke loaʻa iā PCB pōʻino.

Hoʻohana ʻia ʻo SF6 e hāʻawi i kahi tamponade a i ʻole plug o ka lua retina i nā hana hoʻoponopono retina hoʻokaʻawale retina i ke ʻano o kahi ʻōpala kinoea
