CAS No. 2551-62-4 Sulfur Hexafluoride Supplier. Cov yam ntxwv ntawm Sulfur Hexafluoride
Sulfur hexafluoride (SF6) yog cov roj hluavtaws uas tau pom ntau daim ntawv thov thoob plaws ntau yam kev lag luam. CAS tus lej yog 2551-62-4. Nov yog qee cov yam ntxwv ntawm sulfur hexafluoride:
Chemical Properties:
Cov roj formula: SF6
Molecular Luj: Kwv yees li 146.06 g / mol
Kub taw tes: Txog -63.8 ° C
Melting Point: Txog -50.8 ° C
Lub cev muaj zog:
SF6 yog ib qho tsis muaj xim, tsis muaj ntxhiab, tsis muaj nplaim taws.
Nws hnyav dua li huab cua, nrog qhov ceev txog tsib npaug ntawm huab cua ntawm tus qauv.
Nws yog non-reactive nyob rau hauv ib txwm tej yam kev mob tab sis yuav ua tau lom nyob rau hauv high concentrations vim nws muaj peev xwm mus displace oxygen thiab ua rau asphyxiation.
Hluav taws xob cov khoom:
SF6 paub txog nws qhov tshwj xeeb dielectric zog, ua rau nws yog ib qho zoo heev insulator nyob rau hauv high-voltage hluav taws xob cov khoom xws li Circuit Court breakers, switchgear, thiab transformers.
Environmental Impact:
SF6 yog lub tsev cog khoom muaj zog, nrog lub ntiaj teb ua kom sov muaj peev xwm (GWP) tshaj 20 xyoo uas yog kwv yees li 23,500 npaug ntau dua CO2.
Vim nws lub neej ntev ntawm huab cua (kwv yees kwv yees li 3,200 xyoo), tau siv zog los txo nws cov emissions thiab nrhiav lwm txoj hauv kev.
Daim ntawv thov:
Hluav taws xob Engineering: Siv los ua ib qho insulating thiab arc-quenching nruab nrab hauv high-voltage switchgear thiab Circuit Court breakers.
Kev Siv Tshuaj Kho Mob: Siv hauv magnetic resonance imaging (MRI) thiab xam tomography (CT) scans ua tus neeg sawv cev sib txawv.
Hlau Casting: SF6 tuaj yeem siv rau hauv cov txheej txheem casting los tiv thaiv oxidation ntawm molten hlau.
Laser Technology: Nws yog siv rau hauv qee hom lasers.
Kev tuav thiab kev nyab xeeb:
SF6 yuav tsum tau ua tib zoo saib xyuas kom tsis txhob xau, uas tuaj yeem ua rau lub tsev cog khoom tso pa tawm.
Nws yog non-toxic nyob rau hauv nws daim ntawv ntshiab tab sis tuaj yeem tsim kev puas tsuaj yog tias nws decomposes rau hauv cov khoom muaj kuab lom nyob rau hauv arcing tej yam kev mob.
Yuav tsum muaj qhov cua thiab kev saib xyuas kom zoo thaum ua haujlwm nrog SF6 kom ntseeg tau tias cov neeg ua haujlwm muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
