I-sulfur hexafluoride (SF6) iyigesi engeyona eyemvelo, engenambala, engenaphunga, engashi, enamandla kakhulu okushisa, futhi iyisivikelo sikagesi esihle kakhulu.

Isingeniso Somkhiqizo

I-hexafluoride ye-sulfur (SF6) iyigesi yokushisa engeyona into ephilayo, engenambala, engenaphunga, engashi, enamandla kakhulu, futhi iyisivikelo sikagesi esihle kakhulu. I-SF6 ine-geometry ye-octahedral, equkethe ama-athomu ayisithupha e-fluorine anamathele ku-athomu ye-sulfur ephakathi. Iyi-molecule enamandla kakhulu. Ngokuvamile ngegesi engeyona i-polar, ayincibiliki kahle emanzini kodwa incibilika kakhulu ezinyibilikisini eziphilayo ezingeyona i-polar. Ngokuvamile ithuthwa njengegesi ecindezelwe ngoketshezi. Inobuningi obungu-6.12 g/L ezimweni zolwandle, obuphakeme kakhulu kunobuningi bomoya (1.225 g/L).

Isicelo

I-dielectric medium
I-SF6 isetshenziswa embonini kagesi njengendawo yokugaya igesi yama-circuit breaker ane-voltage ephezulu, ama-switchgear, neminye imishini kagesi, ivame ukuthatha indawo yama-circuit breaker agcwele uwoyela (ama-OCB) angaqukatha ama-PCB ayingozi. Igesi le-SF6 ngaphansi kwengcindezi lisetshenziswa njengesivikelo ku-switchgear efakwe igesi (i-GIS) ngoba linamandla aphezulu kakhulu e-dielectric kunomoya noma i-nitrogen eyomile.

Ukusetshenziswa Kwezokwelapha
I-SF6 isetshenziselwa ukuhlinzeka nge-tamponade noma i-plug yembobo ye-retinal emisebenzini yokulungisa i-retinal detachment ngendlela yebhamuza legesi. Ayisebenzi ekamelweni le-vitreous futhi ekuqaleni iphinda kabili ivolumu yayo emahoreni angu-36 ngaphambi kokuba imuncwe egazini ezinsukwini eziyi-10-14.
I-SF6 isetshenziswa njenge-ejenti yokuqhathanisa izithombe ze-ultrasound. Ama-microbubble e-sulfur hexafluoride anikezwa njengesixazululo ngomjovo emthanjeni ongaphandle. Lawa ma-microbubble athuthukisa ukubonakala kwemithambo yegazi ku-ultrasound. Lolu hlelo lokusebenza lusetshenziswe ukuhlola ukuqina kwemithambo yegazi yamathumba.

I-Tracer compound
I-hexafluoride yesibabule kwakuyigesi yokulandelela esetshenziswa ekulinganisweni kokuqala komoya ogeleza emgwaqweni. I-SF6 isetshenziswa njengegesi yokulandelela ezivivinyweni zesikhashana zokusebenza kahle komoya ezakhiweni nasezindaweni ezivalekile zangaphakathi, kanye nokunquma amazinga okungena.
I-hexafluoride yesibabule isetshenziswa njalo njengegesi yokulandelela ekuhlolweni kokugcinwa kwe-fume hood elabhorethri.
Isetshenziswe ngempumelelo njenge-tracer ku-oceanography ukutadisha ukuxubana kwe-diapycnal kanye nokushintshana kwegesi yomoya nolwandle.

Izindaba Ezihlobene

Imakethe ye-Sulfur Hexafluoride Ebiza AmaRandi ayizigidi ezingama-309.9 Ngo-2025
I-SAN FRANCISCO, 14 Nhlolanja 2018

Imakethe yomhlaba wonke ye-sulfur hexafluoride kulindeleke ukuthi ifinyelele ku-USD 309.9 million ngo-2025, ngokusho kombiko omusha we-Grand View Research, Inc. Isidingo esikhulayo somkhiqizo wokusetshenziswa njengento efanelekile yokucima ama-circuit breakers kanye nokukhiqizwa kwe-switchgear kulindeleke ukuthi sibe nomthelela omuhle ekukhuleni kwemboni.

Abahlanganyeli ababalulekile embonini, bahlanganise imisebenzi yabo kulo lonke uchungechunge lwenani ngokuzikhandla ekukhiqizeni izinto zokusetshenziswa kanye nemikhakha yokusabalalisa ukuze bathole ithuba lokuncintisana embonini. Ukutshalwa kwezimali okusebenzayo ku-R&D yomkhiqizo ukunciphisa umthelela wemvelo nokukhulisa ukusebenza kahle kulindeleke ukuthi kwandise ukuncintisana phakathi kwabakhiqizi.
NgoJuni 2014, i-ABB yasungula ubuchwepheshe obunelungelo lobunikazi bokuvuselela igesi ye-SF6 engcolisiwe ngokusekelwe enkambisweni ye-cryogenic esebenza kahle ngamandla. Ukusetshenziswa kwegesi ye-sulfur hexafluoride ephinde yasetshenziswa kulindeleke ukuthi kunciphise ukukhishwa kwekhabhoni cishe ngo-30% futhi konge izindleko. Ngakho-ke, lezi zici kulindeleke ukuthi zikhuthaze ukukhula kwemboni esikhathini esibikezelwe.
Imithetho eqinile ebekwe ekukhiqizweni nasekusetshenzisweni kwe-sulfur hexafluoride (SF6) kulindeleke ukuthi ibe yingozi enkulu kubadlali bemboni. Ngaphezu kwalokho, ukutshalwa kwezimali kokuqala okuphezulu kanye nezindleko zokusebenza ezihlobene nemishini kulindeleke ukuthi kubangele isithiyo sokungena, ngaleyo ndlela kwehlise usongo lwabaqalayo abasha esikhathini esibikezelwe.
Dlulisa amehlo kumbiko ogcwele wocwaningo nge-TOC ku-"Sulfur Hexafluoride (SF6) Market Size Report Ngomkhiqizo (Electronic, UHP, Standard), Ngohlelo Lokusebenza (Amandla Namandla, Ezokwelapha, Ukukhiqiza Insimbi, I-Electronics), kanye Nezibikezelo Zesigaba, 2014 - 2025" ku: www.grandviewresearch.com/industry-analysis/sulfur-hexafluoride-sf6-market
Okunye Okutholakele Okubalulekile Okuvela Kumbiko Kuphakamisa:
• I-SF6 yebanga elijwayelekile kulindeleke ukuthi ibhalise i-CAGR engu-5.7% esikhathini esibekiwe, ngenxa yesidingo sayo esikhulu sokukhiqizwa kwama-circuit breakers kanye nama-switchgear ezitshalweni zokuphehla ugesi namandla.
• Amandla kanye namandla kwakuyisigaba sokusetshenziswa esivelele ngo-2016 lapho i-SF6 engaphezu kuka-75% isetshenziswe ekukhiqizweni kwemishini ye-voltage ephezulu okuhlanganisa izintambo ze-coaxial, ama-transformer, amaswishi, kanye nama-capacitor.
• Lo mkhiqizo kulindeleke ukuthi ukhule ku-CAGR engu-6.0% ekusetshenzisweni kokukhiqiza insimbi, ngenxa yesidingo sawo esikhulu sokuvimbela ukusha kanye nokushiswa okusheshayo kwezinsimbi ezincibilikisiwe embonini yokukhiqiza i-magnesium.
• I-Asia Pacific ibambe isabelo semakethe esikhulu kunazo zonke esingaphezu kuka-34% ngo-2016 futhi kulindeleke ukuthi ibuse imakethe esikhathini esibikezelwe ngenxa yokutshalwa kwezimali okuphezulu emkhakheni wamandla namandla esifundeni.
• I-Solvay SA, i-Air Liquide SA, i-Linde Group, i-Air Products and Chemicals, Inc., kanye ne-Praxair Technology, Inc. basebenzise amasu okukhulisa amandla okukhiqiza ukuze banikeze izidingo zabathengi ezikhulayo futhi bathole amasheya emakethe amakhulu.
