Eminyakeni yamuva, kwakhulisa isithakazelo amakhemikhali ezifana nesibabule hexafluoride. It uphromothiwe kumabonakude izinhlelo ukuzijabulisa, phakathi lapho futhi elalidume kunawo wonke "amahlaya Elihle 'nethi" Mythbusters. " Ikakhulukazi nentshisekelo eziningi yokuthi usebenzisa yalolu ketshezi Ungashintsha iphimbo - kuba aphansi kakhulu. Abantu bacabanga ukuthi ayekubona kuwumqondo omuhle kakhulu ngoba amaqembu, imincintiswano nezinye ukuzijabulisa. Uma kukhona isidingo, kuzoba khona isiphakamiso:-Inthanethi Akunzima ukuthola isikhangiso ukudayiswa sulphur hexafluoride. Kodwa ngaphambi kokuba uphuthume uyowuthenga lento, kuyasiza ukuqonda ukuthi iyini futhi ngabantu iphephe kangakanani.
Sulphur hexafluoride, aka - SF6, ke - sulphur hexafluoride, ke - igesi nangokuvikela, - i wezinto ezingaphili chemical kwakwakhe. Kuyaziwa iminyaka engaphezu kuka-100, futhi oyedwa iye yasetshenziswa ngempumelelo izinjongo zabo. izakhiwo Chemical: i inert, non-enobuthi, igesi esindayo (izikhathi ezingu-5 ngoyisiwula kusinda kunakho emoyeni). Ingqikithi Ayinambala ngokuphelele, has a high ukumelana kagesi kanye okusezingeni eliphezulu ukuwohloka voltage. Kunezindlela ezimbili okungenzeka lasungulwa - izidakamizwa elula yokubola fluorides eziyinkimbinkimbi sulphur. Ngenxa physico-yawo yamakhemikhali izakhiwo isetshenziswa njengenhlangano yisivikelo embonini kagesi, njengoba inqubo uketshezi - e electronics umkhakha, kanye naphakathi inert ukulungiswa Alloys - ebubulweni lesimbi. Muva nje, i-sulphur hexafluoride (isifinyezo "igesi kagesi") lisetshenziswa zokucisha imililo njengoba zokucisha ejenti umlilo. Lawa ububanzi eyinhloko isicelo sulphur hexafluoride.
Kodwa ithelevishini ukuzijabulisa ukunweba ububanzi we ketshezi futhi yawenza ke. Isizathu salokhu kwaba ikhono layo ukushintsha ngelizwi lomuntu: uma imuncwe sulphur hexafluoride, izwi iba ezinkulukazi, ngendlela ephambene neyemvelo ongaphakeme. Kazi kungani lokhu kwenzeka? Izikhathi eziningi ungayithola umbono ukuthi sulphur hexafluoride kuthinta yezwi, kubenze ukuvuvukala yesikhathi esifushane neyezinto ngaleyo ndlela "kwehlisa" izwi. Lena akuyona ngakho. Iqiniso lokuthi zabo yephimbo musa yakha nomsindo omkhulu. ama-apharathasi Vocal yomuntu ngaphandle nemisipha kuhlanganisa kakhudlwana futhi resonators. Enye yalezi resonators - phuza. On the timbre ngomphumela izwi, ikakhulukazi phakathi lokhu elalinembobo. Uma lokhu imvelo - emoyeni, sizwa evamile, ajwayelekile kubo bonke izwi. Kodwa kubalulekile ukuthi ushintshe isimo, futhi sizobe ukuzwa abanye, izwi engajwayelekile. Lokhu kuchazwe isimiso elandelayo: i-ukuxegiselwa igesi kanye ngokushesha ukuhamba molecule ayo, ayanda kuyoba izwi. Ngakolunye uhlangothi, olunesisindo esikhudlwana lwaluba igesi, kancane ukunyakaza kwama-molecule, ithoni aphansi. Helium ulula okungaphezu komoya, ngakho izwi kuphezulu-bamisa, mncane kakhulu nge ephefumula igesi. Sulphur hexafluoride, njengoba sekushiwo, 5 nzima izikhathi ukuba uphefumule futhi uma izwi lakhe liba okwe ongaphakeme. Yilokho: nomphumela ezihlekisayo sulphur hexafluoride ukuchaza ushintsho yesikhashana the elalinembobo imvelo. Inhalation yalolu ketshezi akubhekwa ingozi emzimbeni uma lungenayo aqukethe ukungcola.
Uma ufuna ukuthenga sulphur hexafluoride, intengo akufanele kube determinant ngawe. Akukho ingxabano lokhu kubalulekile, kodwa impilo kuyabiza. Ngakho-ke ukuthenga sulphur hexafluoride, iyabuza umdayisi, the 'emsulwa "Kungakhathaliseki ukuthi hexafluoride ayiqukethe ukuthi iyiphi enye izithasiselo. Lokhu kuzokwenza ukuvikela wena kanye nezivakashi zakho ukuthi uzobe uya ukubungaza hexafluoride nesibabule kuvela lezimanga ezingalindelekile futhi singathandeki.
