Ibi bikoresho ni ibihe?
Helium ni gaze itagira ibara, idafite impumuro nziza, uburyohe butarimo umwuka. Muburyo bwa kamere, helium isanzwe iboneka muke mukirere cyisi nka gaze. Nyamara, ikurwa cyane cyane mumariba ya gaze karemano, aho igaragara cyane.
Ni he wakoresha ibi bikoresho?
Imyidagaduro yo kwidagadura: Helium ikoreshwa cyane cyane mu kuzamura imipira, bigatuma ireremba mu kirere. Iri ni ihitamo rikunzwe mubirori, ibirori nibirori.
Ikirere cy’ikirere: Ibirere byuzuyemo Helium bikoreshwa mu gukusanya amakuru y’ikirere mu bushakashatsi bw’ikirere n’ikirere. Menya ko porogaramu n'amabwiriza yihariye yo gukoresha helium ashobora gutandukana mubihugu, inganda n'intego.
Indege: Imiterere yoroheje-y-ikirere ya helium ituma ikwirakwizwa no gutwara indege na dirigibles. Izi modoka zikoreshwa cyane mukwamamaza, gufotora mu kirere no mu bushakashatsi bwa siyansi.
Cryogenics: Helium ikoreshwa nka coolant muri sisitemu ya cryogenic. Ifite inshingano zo gukomeza ubushakashatsi bwa siyansi, imashini zerekana amashusho (nka scaneri ya MRI) hamwe na magnesi zidasanzwe.
Gusudira: Helium isanzwe ikoreshwa nka gaze ikingira mugikorwa cyo gusudira arc nka gaze ya tungsten inert (TIG). Ifasha kurinda ahantu ho gusudira imyuka yo mu kirere kandi ikanoza ubwiza bwa weld.
Kumenya kumeneka: Helium ikoreshwa nka gaze ya tracer kugirango imenye imyanda muri sisitemu zitandukanye nko kuvoma, sisitemu ya HVAC, nibikoresho bya firigo. Helium yameneka ikoreshwa mugutahura neza no kumenya ibimeneka.
Imvange zihumeka: Abashitsi hamwe n’indege barashobora gukoresha imvange ya heliox, nka heliox na trimix, kugirango birinde ingaruka mbi zo guhumeka umwuka wumuvuduko mwinshi mubwimbitse cyangwa mumwanya.
Ubushakashatsi bwa siyansi: Helium ikoreshwa mubushakashatsi butandukanye bwa siyansi nubushakashatsi bukoreshwa, harimo cryogenics, gupima ibikoresho, magnetiki resonance (NMR) spectroscopy, ndetse na gaze itwara gaze ya chromatografiya.
Menya ko porogaramu n'amabwiriza yihariye yo gukoresha ibi bikoresho / ibicuruzwa bishobora gutandukana mubihugu, inganda n'intego. Buri gihe ukurikize amabwiriza yumutekano kandi ubaze impuguke mbere yo gukoresha ibi bikoresho / ibicuruzwa mubisabwa byose.
