Daim Ntawv Thov
Dielectric nruab nrab
SF6 siv rau hauv kev lag luam hluav taws xob ua cov roj dielectric nruab nrab rau cov hluav taws xob siab, cov switchgear, thiab lwm yam khoom siv hluav taws xob, feem ntau hloov cov roj puv circuit breakers (OCBs) uas tuaj yeem muaj cov PCBs phem. Cov roj SF6 nyob rau hauv qhov siab yog siv ua cov insulator hauv cov roj insulated switchgear (GIS) vim tias nws muaj lub zog dielectric siab dua li cua lossis nitrogen qhuav.
Kev Siv Kho Mob
SF6 yog siv los muab ib lub tamponade lossis ntsaws ntawm lub qhov retinal hauv kev kho retinal detachment hauv daim ntawv ntawm lub npuas roj. Nws yog inert nyob rau hauv lub vitreous chamber thiab pib ob npaug nws lub ntim hauv 36 teev ua ntej nqus tau rau hauv cov ntshav hauv 10-14 hnub.
SF6 yog siv los ua tus neeg sawv cev sib piv rau kev thaij duab ultrasound. Cov npuas me me ntawm sulfur hexafluoride raug muab tso rau hauv cov tshuaj los ntawm kev txhaj tshuaj rau hauv cov leeg ntshav. Cov npuas me me no ua rau pom kev ntawm cov hlab ntsha rau ultrasound. Daim ntawv thov no tau siv los tshuaj xyuas cov hlab ntsha ntawm cov qog nqaij hlav.
Cov tshuaj Tracer
Sulfur hexafluoride yog cov roj tracer siv rau hauv thawj txoj kev ntsuas cov qauv kev sib kis huab cua. SF6 yog siv ua cov roj tracer hauv kev sim luv luv ntawm kev ua haujlwm ntawm qhov cua hauv cov tsev thiab cov chaw nyob sab hauv tsev, thiab rau kev txiav txim siab qhov nqi nkag mus.
Sulfur hexafluoride kuj tseem siv niaj hnub ua cov roj tracer hauv kev sim tshuaj fume hood containment hauv chav kuaj.
Nws tau siv tau zoo ua tus tracer hauv oceanography los kawm txog diapycnal sib xyaw thiab cua-dej hiav txwv roj pauv.

Kev Lag Luam Sulfur Hexafluoride Muaj Nqis $ 309.9 Lab Los Ntawm Xyoo 2025
SAN FRANCISCO, Lub Ob Hlis 14, 2018
Lub lag luam thoob ntiaj teb sulfur hexafluoride yuav tsum ncav cuag USD 309.9 lab los ntawm xyoo 2025, raws li daim ntawv tshaj tawm tshiab los ntawm Grand View Research, Inc. Kev thov khoom nce ntxiv rau cov khoom siv los ua cov khoom siv tua hluav taws xob zoo tshaj plaws hauv kev tsim cov khoom siv hluav taws xob thiab cov khoom siv hloov pauv yuav muaj kev cuam tshuam zoo rau kev loj hlob ntawm kev lag luam.
Cov neeg koom nrog tseem ceeb hauv kev lag luam, tau koom ua ke lawv cov haujlwm thoob plaws hauv cov saw hlau los ntawm kev koom nrog kev tsim cov khoom siv raw thiab cov khoom faib tawm kom tau txais kev sib tw hauv kev lag luam. Kev nqis peev nquag hauv R&D ntawm cov khoom kom txo qhov cuam tshuam rau ib puag ncig thiab txhawb kev ua haujlwm zoo yog kwv yees tias yuav ua rau muaj kev sib tw ntawm cov chaw tsim khoom.
Thaum Lub Rau Hli 2014, ABB tau tsim ib lub tshuab patent los siv cov roj SF6 uas muaj kuab paug raws li cov txheej txheem cryogenic uas siv zog tau zoo. Kev siv cov roj sulfur hexafluoride uas siv rov qab tau xav tias yuav txo cov pa roj carbon dioxide li ntawm 30% thiab txuag cov nqi. Yog li ntawd, cov yam no yuav ua rau kev lag luam loj hlob sai dua thaum lub sijhawm kwv yees.
Cov kev cai nruj uas tau tsim los rau kev tsim khoom thiab kev siv cov tshuaj sulfur hexafluoride (SF6) yuav yog qhov kev hem thawj tseem ceeb rau cov neeg ua lag luam hauv kev lag luam. Ntxiv mus, kev nqis peev thaum pib siab thiab cov nqi ua haujlwm cuam tshuam nrog cov tshuab yuav ua rau muaj kev cuam tshuam, yog li txo qhov kev hem thawj ntawm cov neeg nkag tshiab hauv lub sijhawm kwv yees.
