ʻO ka Sulfur Hexafluoride (SF6)

Nā palena loea

ʻO ka sulfur hexafluoride, nona ke ʻano kemika ʻo SF6, he kinoea paʻa ʻole kona kala, ʻala ʻole, ʻaʻohe mea ʻawahia, a ʻaʻole hiki ke lapalapa. He kinoea ʻo sulfur hexafluoride ma lalo o ka mahana maʻamau a me ke kaomi, me nā waiwai kemika paʻa, hoʻoheheʻe iki ʻia i ka wai, ka waiʻona a me ka ether, hoʻoheheʻe ʻia i loko o ka potassium hydroxide, a ʻaʻole ia e pane kemika me ka sodium hydroxide, ka ammonia wai a me ka waikawa hydrochloric. ʻAʻole ia e pane me ke keleawe, ke kālā, ka hao, a me ka alumini i kahi maloʻo ma lalo o 300°C. Ma lalo o 500℃, ʻaʻohe ona hopena i ka quartz. Hoʻopili ia me ka sodium metala ma 250°C, a pane i ka ammonia wai ma -64°C. E palaho ia ke hui pū ʻia me ka hydrogen sulfide a hoʻomehana ʻia. Ma 200℃, i ke alo o kekahi mau metala e like me ke kila a me ke kila silicon, hiki iā ia ke hoʻolaha i kona palaho lohi. ʻO ka Sulfur hexafluoride kahi hanauna hou o ka mea hoʻokaʻawale uila ultra-kiʻekiʻe, kahi i hoʻohana nui ʻia no ka hoʻokaʻawale kinoea o nā mea uila, nā lako uila a me nā alakaʻi nalu radar, a ma ke ʻano he mea hoʻokaʻawale no ka hoʻopau ʻana i ke arc a me nā mea hoʻololi mana nui i nā kuapo uila kiʻekiʻe. ʻO nā pono o nā laina hoʻoili paipu SF6 gas-insulated he pohō dielectric haʻahaʻa, ka nui o ka hoʻoili ʻana, a hiki ke hoʻohana ʻia i nā manawa hāʻule kiʻekiʻe. Loaʻa i ka mea hoʻololi insulated gas SF6 nā pono o ke ahi a me ka pale ʻana i ka pahū. Loaʻa iā Sulfur hexafluoride nā ʻano o ke kūpaʻa kemika maikaʻi a me ka pale ʻole i nā lako. Hiki ke hoʻohana ʻia ma ke ʻano he refrigerant i ka ʻoihana refrigeration (mahana hana ma waena o -45 ~ 0 ℃). ʻO ka sulfur hexafluoride maʻemaʻe kiʻekiʻe o ka papa uila he mea hoʻoheheʻe uila kūpono, kahi i hoʻohana nui 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 ʻāpana kamepiula a me nā pale kristal wai. Nā hana palekana mālama: E mālama i loko o kahi hale kūʻai anuanu a ventilated. E mālama mamao mai ke ahi a me nā kumu wela. ʻAʻole pono e ʻoi aku ka mahana o ka mālama ʻana ma mua o 30°C. Pono e mālama ʻokoʻa ʻia mai nā mea ʻā maʻalahi (hiki ke puhi) a me nā mea hoʻoheheʻe ʻia, a pale i ka mālama ʻana i nā mea like ʻole. Pono e hoʻolako ʻia kahi mālama me nā lako hana lapaʻau ulia pōpilikia liki.

Noi:

①Mea waena Dielectric:

Hoʻohana ʻia ʻo SF6 i ka ʻoihana uila ma ke ʻano he wahie dielectric kinoea no nā mea haki kaapuni kiʻekiʻe-voltage, switchgear, a me nā lako uila ʻē aʻe, e pani pinepine ana i nā mea haki kaapuni i hoʻopiha ʻia i ka ʻaila (OCB) hiki ke loaʻa nā PCB ʻino.

②Hoʻohana lapaʻau:

Hoʻohana ʻia ʻo SF6 e hāʻawi i kahi tamponade a i ʻole plug o kahi lua retinal i nā hana hoʻoponopono retinal detachment ma ke ʻano o kahi pehu kinoea.

③Hua hoʻopili:

Hoʻohana ʻia ʻo SF6 e hāʻawi i kahi tamponade a i ʻole plug o kahi lua retinal i nā hana hoʻoponopono retinal detachment ma ke ʻano o kahi pehu kinoea.

Pōmaikaʻi:

①High maemae, hale hou loa;

②Mea hana palapala hōʻoia ISO;

③Hoʻouna wikiwiki;

④Nā mea maka paʻa mai ka lako o loko;

⑤ʻŌnaehana loiloi pūnaewele no ka kaohi maikaʻi i kēlā me kēia ʻanuʻu;

⑥Kūpono kiʻekiʻe a me ke kaʻina hana meticulous no ka lawelawe ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;
