Intshayelelo yeMveliso
I-Sulfur hexafluoride (SF6) yigesi yegreenhouse engabonakaliyo, engenambala, engenavumba, engatshiyo, enamandla kakhulu, kwaye iyi-insulator yombane ebalaseleyo. I-SF6 ine-geometry ye-octahedral, equlathe ii-athomu ezintandathu ze-fluorine ezinamathele kwi-athomu yesalfure ephakathi. Yimolekyuli ene-hypervalent. Ngokuqhelekileyo kwigesi engeyiyo i-polar, ayinyibiliki kakuhle emanzini kodwa iyanyibilika kakhulu kwi-nonpolar organic solvents. Ngokuqhelekileyo ithuthwa njengegesi ecinezelweyo emanzi. Inoxinano lwe-6.12 g/L kwiimeko zolwandle, oluphezulu kakhulu kunoxinano lomoya (1.225 g/L).

Isicelo
Isixhobo sombane esiphakathi
I-SF6 isetyenziswa kwishishini lombane njengesixhobo sombane esisebenzisa igesi kwizixhobo zombane ezine-voltage ephezulu, i-switchgear, kunye nezinye izixhobo zombane, idla ngokuthatha indawo yezixhobo zombane ezizaliswe yioyile (ii-OCB) ezinokuqulatha ii-PCB eziyingozi. Igesi ye-SF6 ephantsi koxinzelelo isetyenziswa njengesigqubuthelo kwi-switchgear egqunywe yigesi (i-GIS) kuba inamandla aphezulu e-dielectric kunomoya okanye i-nitrogen eyomileyo.
Ukusetyenziswa kwezonyango
I-SF6 isetyenziselwa ukubonelela nge-tamponade okanye iplagi yomngxuma we-retinal kwimisebenzi yokulungisa i-retinal detachment ngendlela yebhamuza yegesi. Ayisebenzi kwigumbi le-vitreous kwaye ekuqaleni iphinda kabini umthamo wayo kwiiyure ezingama-36 ngaphambi kokuba ifunxwe egazini kwiintsuku ezili-10-14.
I-SF6 isetyenziswa njengesixhobo sokulinganisa imifanekiso ye-ultrasound. Ii-microbubbles ze-sulfur hexafluoride zifakwa kwisisombululo ngokujova kwi-peripheral vein. Ezi microbubbles ziphucula ukubonakala kwemithambo yegazi kwi-ultrasound. Olu setyenziso lusetyenziselwe ukuhlola ukuqina kwemithambo yegazi yeethumba.
I-Tracer compound
I-hexafluoride yesulfuri yayiyigesi yokulandelela esetyenzisiweyo kwimodeli yokuqala yokulinganisa ukusasazwa komoya endleleni. I-SF6 isetyenziswa njengegesi yokulandelela kwiimvavanyo zexesha elifutshane zokusebenzisa kakuhle umoya kwizakhiwo nakwiindawo ezivalekileyo zangaphakathi, kunye nokumisela amazinga okungena kwamanzi.
I-hexafluoride yesulfure ikwasetyenziswa rhoqo njengegesi yokulandelela xa kusenziwa uvavanyo lokuthintela umsi kwi-laboratory.
Isetyenziswe ngempumelelo njenge-tracer kwi-oceanography ukufunda ukuxubana kwe-diapycnal kunye nokutshintshiselana kwegesi phakathi komoya nolwandle.
