Sulfur Hexafluoride (SF6)

Technical parameters

Sulfur hexafluoride, uas nws cov tshuaj formula yog SF6, yog xim tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab tsis-flammable stability gas. Sulfur hexafluoride yog gaseous nyob rau hauv ib txwm kub thiab siab, nrog cov tshuaj ruaj khov, me ntsis soluble nyob rau hauv dej, cawv thiab ether, soluble nyob rau hauv poov tshuaj hydroxide, thiab tsis hnov ​​mob chemically nrog sodium hydroxide, kua ammonia thiab hydrochloric acid. Nws tsis cuam tshuam nrog tooj liab, nyiaj, hlau, thiab txhuas hauv qhov chaw qhuav hauv qab 300 ° C. Hauv qab 500 ℃, nws tsis cuam tshuam rau quartz. Nws reacts nrog hlau sodium ntawm 250 ° C, thiab reacts nyob rau hauv kua ammonia ntawm -64 ° C. Nws yuav decompose thaum tov nrog hydrogen sulfide thiab rhuab. Ntawm 200 ℃, nyob rau hauv muaj qee yam hlau xws li hlau thiab silicon steel, nws tuaj yeem txhawb nqa nws qeeb decomposition. Sulfur hexafluoride yog ib tiam tshiab ntawm ultra-high voltage insulating khoom, uas yog dav siv rau roj rwb thaiv tsev ntawm electronics, hluav taws xob khoom thiab radar waveguides, thiab raws li ib tug insulating cov ntaub ntawv rau arc extinguishing thiab loj-muaj peev xwm transformers nyob rau hauv high-voltage keyboards. Qhov zoo ntawm SF6 gas-insulated pipeline kis tau tus mob yog tsis tshua muaj dielectric poob, muaj peev xwm kis tau tus mob loj, thiab yuav siv tau nyob rau hauv lub sij hawm poob siab. SF6 gas insulated transformer muaj qhov zoo ntawm kev tiv thaiv hluav taws thiab tawg. Sulfur hexafluoride muaj cov yam ntxwv ntawm kev ruaj ntseg tshuaj zoo thiab tsis-corrosion 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 ~ 0 ℃). Electronic qib high-purity sulfur hexafluoride yog ib qho zoo tagnrho hluav taws xob etchant, uas yog dav siv nyob rau hauv lub teb ntawm microelectronics technology raws li ib tug plasma etching thiab ntxuav tus neeg saib xyuas nyob rau hauv lub tsim ntawm loj integrated circuits xws li lub computer chips thiab kua siv lead ua ntxaij. Kev ceev faj cia: Khaws rau hauv qhov chaw txias, qhov cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Qhov kub cia yuav tsum tsis pub tshaj 30 ° C. Nws yuav tsum tau muab cais los ntawm yooj yim (combustible) combustibles thiab oxidants, thiab tsis txhob sib tov cia. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.

Daim ntawv thov:

① 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.

② Kev siv tshuaj 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.

③Tracer compound:

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.
