Sulfur Hexafluoride
Sulfur Hexafluoride(SF6) yog ib qho inorganic, tsis muaj xim, tsis muaj ntxhiab, thiab tsis-flammable gas.SF6 thawj siv yog nyob rau hauv cov hluav taws xob kev lag luam raws li ib tug gaseous dielectric nruab nrab rau ntau yam voltage Circuit Court breakers, switchgear thiab lwm yam khoom siv hluav taws xob, feem ntau hloov roj puv Circuit Court breakers (OCBs) uas muaj peev xwm muaj teeb meem PCBs.SF6 roj nyob rau hauv siab yog siv los ua ib qho insulator nyob rau hauv gas insulated switchgear (GIS) vim hais tias nws muaj ib tug ntau dua dielectric zog tshaj huab cua los yog qhuav nitrogen.Cov cuab yeej no ua rau nws muaj peev xwm txo qhov loj ntawm cov khoom siv hluav taws xob.

Sulfur hexafluoride (SF6) feem ntau muaj nyob rau hauv lub tog raj kheej thiab lub nruas tank.Nws feem ntau yog siv hauv qee qhov kev lag luam suav nrog:
1) Lub zog & Lub Zog: Feem ntau yog siv los ua qhov nruab nrab insulating rau ntau yam khoom siv hluav taws xob thiab hluav taws xob xws li hluav taws xob hluav taws xob, hloov lub zog thiab cov khoom siv accelerators.
2) Iav: Insulating qhov rais - txo suab kis tau tus mob thiab hloov tshav kub.
3) Hlau & Hlau: Hauv molten magnesium thiab aluminium ntau lawm thiab purification.
4) Electronics: High purity sulfur hexafluoride siv hauv kev siv hluav taws xob thiab semiconductor.
