Na Sulfur Hexafluoride e Chefo?

Sulfur hexafluorideke motsoako oa inorganic o nang le foromo ea lik'hemik'haleSF6. Ke khase e tsitsitseng e se nang 'mala, e sa nkheng, e se nang chefo, e sa cheseng mocheso oa kamore le khatello. Boima ba eona ba molek'hule ke 146.055. Boima ba eona ke 6.0886 kg / m3 ho 20 ° C le 0.1 MPa, e leng hoo e ka bang makhetlo a 5 ho feta moea. Sebopeho sa limolek'hule tsasebabole hexafluorideke octahedral, e nang le sebaka se senyenyane sa ho tlamahanngoa le matla a matla a ho kopanya. Ka hona, e na le botsitso bo phahameng. Ha mocheso o sa fete 180 ° C, ho lumellana ha eona le thepa ea mohaho oa motlakase ho tšoana le ea naetrojene.

Nasebabole hexafluoridechefo? Hloekilengsebabole hexafluorideke khase ea inert e senyehang tlas'a ts'ebetso ea arc ea motlakase. Ha mocheso o le ka holimo ho 4000K, boholo ba lihlahisoa tsa ho bola ke liathomo tse le 'ngoe tsa sebabole le fluorine. Ka mor'a hore arc e time, boholo ba lihlahisoa tsa ho bola li kopana hape ho ba tse tsitsitsengsebabole hexafluoridelimolek'hule. Nakong ea ts'ebetso ea ho kopanya hape, lihlahisoa tse fokolang haholo tsa lihlahisoa li itšoara ka liathomo tsa tšepe tse sa lefelloeng, metsi le oksijene ho etsa tšepe ea fluoride le fluoride ea oksijene le sebabole. Nengsebabole hexafluoridee sebelisoa lisebelisoa tsa motlakase, e ka bola ho tsoa ho oksijene le sebabole tlas'a maemo a phoso kapa li-arcs tse tloaelehileng tsa ho robeha 'me ea hlahisa phofo ea fluoride le metal fluoride.

Phihlelo e bontšitse hore esita le libakeng tse nang le lihlahisoa tse nyenyane haholo tsa ho bola, basebetsi ba ka ba le monko o hlabang kapa o sa thabiseng le ho teneha ho hoholo nkong, molomong le mahlo. Boitšoaro bona bo etsahala ka mor'a metsotsoana e seng mekae pele ho etsahala lintho tse chefo.

Nengsebabole hexafluoridechefo e etsahala, hangata e bakoa ke ho senyeha ha eona ka li-arcs tse phahameng tsa lisebelisoa tsa motlakase. Ka hona, e hloekilengsebabole hexafluorideha e na chefo, empa re lokela ho ela hloko lintho tse chefo tse bolileng kesebabole hexafluoride. Joale, ke lintho life tse chefo tse bolileng ka tsonasebabole hexafluoridekhase lisebelisoa tsa motlakase?

1. Lintho tse ling tse chefo tse hlahisoang kesebabole hexafluoridekhase lisebelisoa tsa motlakase ha mocheso o phahameng oa mocheso o hlaha.
2.Sulfur hexafluoridekhase le lihlahisoa tsa ho bola ka lisebelisoa tsa motlakase li sebetsana le li-electrode (alloy ea koporo-tungsten) le lisebelisoa tsa tšepe (aluminium, koporo) ho hlahisa lintho tse chefo.
3. The decomposition dihlahiswa tsasebabole hexafluoridekhase ea lisebelisoa tsa motlakase e arabelana le metsi ho eona ho hlahisa lintho tse chefo.
4.Sulfur hexafluoridelihlahisoa ha lia hloeka 'me li na le chefo e ngata ea low-sulfur fluoride, hydrogen fluoride le likhase tse ling tse chefo ha li tloha fekthering.
5.Sulfur hexafluoridekhase le lihlahisoa tsa ho bola ka thepa ea motlakase li sebetsana le lisebelisoa tse sireletsang ho hlahisa lintho tse chefo, tse kang epoxy phenolic fiberglass masela a mapolanka (lithupa, li-tubes) tse nang le silicon bakeng sa likarolo tsa insulating; kapa li-castings tsa epoxy resin, likarolo tse bōpiloeng, libotlolo tsa porcelain, rabara ea silicone, mafura a silicone, joalo-joalo Ka lehlabathe la quartz le khalase e le li-fillers, lik'hemik'hale tsa lik'hemik'hale li etsahala ho hlahisa lihlahisoa tse kang SiF4 le Si (CH3) 2F2.
