Daim ntawv thov
Dielectric nruab nrab
SF6 yog siv nyob rau hauv kev lag luam hluav taws xob raws li ib tug gaseous dielectric nruab nrab rau high-voltage circuit 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.
Kev siv kho mob
SF6 yog siv los muab lub tamponade los yog ntsaws ntawm lub qhov retinal nyob rau hauv retinal detachment kho cov hauj lwm nyob rau hauv daim ntawv ntawm ib tug roj npuas. Nws yog inert nyob rau hauv lub vitreous chamber thiab pib doubles nws ntim nyob rau hauv 36 teev ua ntej absorbed nyob rau hauv cov ntshav nyob rau hauv 10-14 hnub.
SF6 yog siv los ua tus neeg sawv cev sib txawv rau kev kuaj xyuas ultrasound. Sulfur hexafluoride microbubbles yog siv rau hauv kev daws los ntawm kev txhaj tshuaj rau hauv cov hlab ntsha peripheral. Cov microbubbles no txhim kho qhov pom ntawm cov hlab ntsha mus rau ultrasound. Daim ntawv thov no tau siv los tshuaj xyuas vascularity ntawm cov qog.
Tracer compund
Sulfur hexafluoride yog cov tracer gas siv nyob rau hauv thawj txoj kev huab cua dispersion qauv calibration.SF6 yog siv raws li ib tug tracer gas nyob rau hauv lub sij hawm luv luv thwmsim ntawm cua efficiency nyob rau hauv lub tsev thiab sab hauv tsev enclosures, thiab txiav txim infiltration tus nqi.
Sulfur hexafluoride tseem niaj hnub siv los ua cov pa roj tracer hauv chav kuaj fume hood container test.
Nws tau raug siv ua tiav raws li tus neeg taug qab hauv dej hiav txwv los kawm txog kev sib xyaw diapycnal thiab huab cua-hiav txwv sib pauv.
