I-Sulfur Hexafluoride (SF6)

Iiparamitha zobugcisa

I-Sulfur hexafluoride, enefomula yekhemikhali eyi-SF6, yigesi engenambala, engenavumba, engeyotyhefu, nengatshiyo ezinzileyo. I-Sulfur hexafluoride i-gaseous phantsi kobushushu obuqhelekileyo kunye noxinzelelo, kunye neepropati ezizinzileyo zeekhemikhali, i-soluble kancinane emanzini, utywala kunye ne-ether, i-soluble kwi-potassium hydroxide, kwaye ayisebenzi ngamakhemikhali kunye ne-sodium hydroxide, i-ammonia engamanzi kunye ne-hydrochloric acid. Ayichaphazeli ubhedu, isilivere, intsimbi, kunye ne-aluminiyam kwindawo eyomileyo engaphantsi kwe-300°C. Ngaphantsi kwe-500℃, ayinasiphumo kwiquartz. Isabela ngesinyithi esinesodium kwi-250°C, kwaye isabela kwi-ammonia engamanzi kwi -64°C. Iya kubola xa ixutywe ne-hydrogen sulfide kwaye ishushu. Kwi-200℃, phambi kweentsimbi ezithile ezifana nentsimbi kunye ne-silicon, inokukhuthaza ukubola kwayo okucothayo. I-Sulfur hexafluoride sisizukulwana esitsha se-ultra-high-voltage insulating material, esetyenziswa ngokubanzi ukugquma igesi yombane, izixhobo zombane kunye ne-radar waveguides, nanjengesixhobo sokukhusela ukucima i-arc kunye neziguquli ezinomthamo omkhulu kwizitshixo zombane ophezulu. Iinzuzo ze-SF6 ye-gas-insulated imigca yothumelo lwemibhobho yilahleko ephantsi ye-dielectric, umthamo omkhulu wothumelo, kwaye ingasetyenziswa kwiimeko zokuhla okuphezulu. I-SF6 gas insulated transformer ineenzuzo zokukhusela umlilo kunye nokudubula. I-Sulfur hexafluoride ineempawu zokuzinza kweekhemikhali ezilungileyo kunye nokungagqwali kwizixhobo. Ingasetyenziswa njenge friji kwishishini lefriji (ubushushu bokusebenza phakathi kwe -45 ~ 0 ℃). I-Electronic grade high-purity sulfur hexafluoride yi-etchant ye-elektroniki efanelekileyo, esetyenziswa ngokubanzi kwi-teknoloji ye-microelectronics njenge-etching ye-plasma kunye ne-arhente yokucoca ekwenzeni iisekethe ezinkulu ezidibeneyo ezifana ne-computer chips kunye nezikrini zekristale zolwelo. Amanyathelo okhuseleko: Gcina kwindawo epholileyo, nengena umoya. Zigcine kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina akufunekanga budlule kuma-30°C. Kufuneka igcinwe ngokwahlukileyo kwizinto ezinokutsha ezilula (ezinokutsha) kunye ne-oxidants, kwaye ugweme ukugcinwa okuxubileyo. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.

Isicelo:

①Idielectric medium:

I-SF6 isetyenziswa kushishino lombane njenge gaseous dielectric medium for high-voltage circuit breakers, switchgear, kunye nezinye izixhobo zombane, ezihlala zithatha indawo yeoyile ezaliswe zii-circuit breakers (OCBs) ezinokuqulatha iiPCB eziyingozi.

②Ukusetyenziswa kwezonyango:

I-SF6 isetyenziselwa ukubonelela ngetamponade okanye iplagi yomngxuma we-retinal kwimisebenzi yokulungisa i-retinal detachment ngendlela ye-bubble yegesi.

③Ikhompawundi yeTracer:

I-SF6 isetyenziselwa ukubonelela ngetamponade okanye iplagi yomngxuma we-retinal kwimisebenzi yokulungisa i-retinal detachment ngendlela ye-bubble yegesi.
