Isilinda segesi ye-Helium

Incazelo emfushane:

Isilinda segesi isitsha sokucindezela ukuze sigcinwe futhi sinqande amagesi ngaphezu komfutho womkhathi.

Amasilinda egesi anengcindezi ephezulu abizwa nangokuthi amabhodlela.Ngaphakathi kusilinda okuqukethwe okugciniwe kungase kube sesimweni segesi ecindezelweyo, umhwamuko phezu koketshezi, uketshezi oluningi kakhulu, noma kuncibilike endaweni engaphansi, kuye ngezici ezibonakalayo zokuqukethwe.

Idizayini evamile yesilinda segesi inwetshiwe, ime iqonde ekugcineni esiphansi esiyisicaba, nevalvu futhi ifaneleka phezulu ukuze ixhumeke emshinini owamukelayo.

Isicelo

I-Helium isetshenziswa kakhulu embonini yezempi, ucwaningo lwesayensi, i-petrochemical, isiqandisi, ukwelashwa, i-semiconductor, ukutholwa kokuvuza kwepayipi, ukuhlolwa kwe-superconductivity, ukukhiqizwa kwensimbi, ukujula kolwandle, ukushisela okunembayo, ukukhiqizwa komkhiqizo we-optoelectronic, njll.

(1) Ukupholisa kwezinga lokushisa eliphansi: Ngokusebenzisa indawo yokubilisa ephansi ye-helium ewuketshezi engu -268.9 °C, i-helium ewuketshezi ingasetshenziselwa ukupholisa izinga lokushisa eliphansi kakhulu.Ubuchwepheshe bokupholisa izinga lokushisa eliphansi kakhulu bunohlu olubanzi lwezinhlelo zokusebenza kubuchwepheshe be-superconducting neminye imikhakha.Izinto ze-Superconducting zidinga ukuba ezingeni lokushisa eliphansi (cishe 100K) ukukhombisa izakhiwo ze-superconducting.Ezimweni eziningi, i-helium ewuketshezi kuphela engafinyelela kalula izinga lokushisa eliphansi kakhulu..Ubuchwepheshe be-Superconducting busetshenziswa kakhulu ezitimeleni ze-maglev embonini yezokuthutha kanye nemishini ye-MRI emkhakheni wezokwelapha.

(2) Ukwehla kwamandla emali ebhaluni: Njengoba ukuminyana kwe-helium kukuncane kakhulu kunomoya (ukuminyana komoya kungu-1.29kg/m3, ukuminyana kwe-helium ngu-0.1786kg/m3), futhi izakhiwo zamakhemikhali azisebenzi ngokwedlulele, okusho ukuthi iphephe kune-hydrogen (i-hydrogen ingaba semoyeni evutha umlilo, mhlawumbe iziqhumane), i-helium ivamise ukusetshenziswa njengegesi yokugcwalisa kumikhumbi-mkhathi noma amabhaluni okukhangisa.

(3) Ukuhlola nokuhlaziya: Ozibuthe abakhulu bezihlaziyi ze-nuclear magnetic resonance ezivame ukusetshenziswa ekuhlaziyeni izinsimbi kudingeka bapholiswe nge-helium ewuketshezi.Ekuhlaziyweni kwe-chromatography yegesi, i-helium ivamise ukusetshenziswa njengegesi ethwala.Kusetshenziswa ithuba elihle lokukwazi ukungena nokungashi kwe-helium, i-helium Ibuye isetshenziswe ekutholeni ukuvuza kwe-vacuum, njengezithonjana zokuvuza kwe-helium mass spectrometer.

(4) Igesi yokuvikela: Isebenzisa izakhiwo zamakhemikhali ezingasebenzi ze-helium, i-helium ivame ukusetshenziswa njengegesi yokuvikela ukushisela i-magnesium, i-zirconium, i-aluminium, i-titanium nezinye izinsimbi.

(5) Ezinye izici: I-Helium ingasetshenziswa njengegesi ecindezelwe ukuthutha ama-propellants oketshezi njenge-hydrogen ewuketshezi nomoya-mpilo we-liquid kumarokhethi kanye nemikhumbi-mkhathi emishinini yevacuum ephezulu nama-reactors enuzi.I-Helium iphinde isetshenziswe njenge-ejenti yokuhlanza ama-reactors e-athomu, kugesi exubekile yokuphefumula emkhakheni wokuthuthukiswa kwasolwandle, njengegesi yokugcwalisa ama-thermometers wegesi, njll.
