SF6 gas Taw qhia

sf6

SF6 roj muaj keeb kwm dhau ib puas xyoo. Nws yog ib tug txiv neej- ua cov roj inert synthesized nyob rau hauv 1900 los ntawm ob tug Fabkis chemists, Moissan thiab Lebeau. Nyob ib ncig ntawm 1940, Asmeskas tub rog siv nws hauv Manhattan Project.

SF6 yog cov pa roj electronegative heev. Nws cov molecules tau yooj yim adsorb dawb electrons los tsim cov ions tsis zoo, ua rau cov txheej txheem sib tsoo ionization hauv cov pa tsis muaj zog. Yog li ntawd, nws cov hluav taws xob rwb thaiv tsev lub zog yog siab heev, kwv yees li 2.5 npaug ntawm huab cua nyob rau hauv ib qho hluav taws xob tsis zoo.

SF6 gas Siv Hauv cov khoom siv hluav taws xob

Txij li thaum nruab nrab -1960s, SF6 tau dav siv los ua ib qho nruab nrab insulating hauv siab - cov khoom siv hluav taws xob hluav taws xob. SF6 gas- insulated tag nrho cov khoom siv hluav taws xob nyob hauv thaj chaw me dua li cov pa qhib - hom siab - cov khoom siv hluav taws xob hluav taws xob, thiab nws txoj haujlwm tsis cuam tshuam los ntawm huab cua sab nraud thiab ib puag ncig. Yog li ntawd, nws yog dav siv tsis tau tsuas yog nyob rau hauv ultra{10}} high voltage thiab extra-high voltage fais fab nroj tsuag, tab sis kuj tau pib siv nyob rau hauv tis network.

Nws yog tsuas yog siv rau arc extinguishing nyob rau hauv siab -voltage switches thiab raws li ib tug insulating cov ntaub ntawv nyob rau hauv loj- muaj peev xwm transformers thiab siab -voltage cables. SF6 tuaj yeem siv los ua cov khoom siv hluav taws xob hauv hluav taws xob hauv cov khoom siv hluav taws xob nuclear thiab X- cov khoom siv hluav taws xob rau cov neeg tua hluav taws. Vim nws cov tshuaj lom neeg ruaj khov zoo thiab tsis yog -corrosiveness rau cov khoom siv, nws tuaj yeem siv los ua cov tub yees hauv kev lag luam tub yees (kev ua haujlwm kub ntawm -45℃thiab 0℃). SF6 muaj peev xwm nres siab rau alpha hais, yog li nws kuj muaj cov ntawv thov hauv radiochemistry. Nws kuj tseem siv tau los ua cov desorbent los hloov cov pa oxygen hauv cov hmoov av ntawm cov mines.

Vim li cas thiaj hais tias SF6 gas muaj teeb meem

Qhov tseem ceeb tshaj plaws thiab teeb meem loj nrog SF6 roj yog nws ib puag ncig muaj kuab paug.

SF6 roj muaj cov nyhuv tsev cog khoom muaj zog heev. Ib kilogram ntawm SF6 roj muaj cov nyhuv tsev cog khoom sib npaug rau 23,500 kilograms ntawm carbon dioxide. Tam sim no nws yog cov khoom uas muaj zog tshaj plaws tsev cog khoom nyhuv. Kyoto raws tu qauv txwv tsis pub emission ntawm SF6 roj.

SF6 tuaj yeem nyob hauv huab cua mus txog 3200 xyoo. Piv txwv li, SF6 peb emit niaj hnub no yuav muaj nyob rau hauv lub ntiaj teb rau ntau txhiab xyoo.

Cov khoom decomposition ntawm SF6 roj nyob rau hauv siab -voltage hluav taws xob arcs muaj kev puas tsuaj rau lub ozone txheej.

SF6 roj nws tus kheej tsis yog - lom, tab sis nws decomposes nyob rau hauv high voltage thiab kub nyob rau hauv cov khoom siv hluav taws xob, tsim cov khoom decomposition. Cov khoom no hnov mob nrog dej, huab cua, thiab oxygen los tsim ntau yam tshuaj lom. Cov tshuaj lom neeg no yog cov tshuaj lom ntau tshaj li phosgene, thiab muaj zog ua rau khaus thiab corrosive rau tib neeg txoj kev ua pa, thaum tseem muaj corrosive rau cov hlau thiab cov khoom siv insulating.
