Helium ikoreshwa cyane, Kuki ukoresha imipira ya helium?

Mubyinshi nyuma ya 80 na 80 nyuma yubwana, imipira ya hydrogène yari ingenzi.Noneho, imiterere ya ballon ya hydrogen ntikigarukira gusa kumashusho.Hariho kandi imipira myinshi itukura itukura ibonerana itatse amatara, ikundwa nurubyiruko rwinshi.

Nyamara, imipira ya hydrogen ni mbi cyane.Iyo hydrogène imaze kuba mu kirere hanyuma igasiga hamwe n'ibindi bintu kugira ngo itange amashanyarazi ahamye, cyangwa ihure n'umuriro ufunguye, biroroshye guturika.Muri 2017, byavuzwe ko abasore bane bo muri Nanjing baguze imipira itandatu itukura kuri interineti, ariko umwe muri bo yatunguye impanuka ku mupira igihe yari anywa itabi.Kubera iyo mpamvu, imipira itandatu yaturikiyeho, bituma abantu benshi batwikwa cyane.Babiri muri bo kandi bari bafite ibisebe mu ntoki, kandi mu maso hageze mu cyiciro cya II.

Kubwumutekano, ubundi bwoko bwa "helium balloon" bwagaragaye kumasoko.Ntibyoroshye guturika no gutwika, kandi bifite umutekano kuruta ballon ya hydrogen.

Kuki ukoresha imipira ya helium

Reka tubanze twumve impamvu helium ishobora gutuma imipira iguruka.

Imyuka isanzwe yuzuza imipira ni hydrogen na helium.Kubera ko ubwinshi bwiyi myuka yombi buri munsi yu mwuka, ubwinshi bwa hydrogène ni 0.09kg / m3, ubucucike bwa helium ni 0.18kg / m3, naho ubwinshi bw’umwuka ni 1.29kg / m3.Kubwibyo, iyo bitatu bihuye, umwuka wuzuye uzamura hejuru witonze, kandi ballon ireremba hejuru bikomeza bitewe na buoyancy.

Mubyukuri, hariho imyuka myinshi ifite ubucucike buri munsi yumuyaga, nka ammonia ifite ubucucike bwa 0,77kg / m3.Ariko, kubera ko impumuro ya ammonia irakaze cyane, irashobora kwandikwa byoroshye kuruhu rwa mucosa na conjunctiva, bigatera uburakari no gutwika.Kubwimpamvu z'umutekano, ammonia ntishobora kuzuzwa muri ballon.

Helium ntabwo iri munsi yubucucike gusa, ariko kandi biragoye kuyitwika, bityo ibaye umusemburo mwiza wa hydrogen.

Helium ntishobora gukoreshwa gusa, ariko kandi irashobora gukoreshwa cyane.

Helium ikoreshwa cyane

Niba utekereza ko helium ishobora gukoreshwa mukuzuza imipira gusa, uribeshya.Mubyukuri, helium ifite ibirenze izi ngaruka kuri twe.Ariko, helium ntacyo imaze.Ndetse ni ngombwa cyane mu nganda za gisirikare, ubushakashatsi bwa siyansi, inganda nizindi nzego nyinshi.

Iyo gushonga no gusudira ibyuma, helium irashobora gutandukanya umwuka wa ogisijeni, bityo irashobora gukoreshwa mugukora ibidukikije bikingira kugirango hirindwe imiti hagati yibintu na ogisijeni.

Byongeye kandi, helium ifite aho itetse cyane kandi irashobora no gukoreshwa nka firigo.Helium ya Liquid ikoreshwa cyane nkigikoresho cyo gukonjesha no gusukura ibyuma bya atome.Muri icyo gihe, irashobora kandi gukoreshwa nka kuzamura no kuzamura amavuta ya roketi.Ugereranije, NASA ikoresha miriyoni amagana ya metero kibe ya helium buri mwaka mubushakashatsi bwa siyansi.

Helium ikoreshwa kandi ahantu henshi mubuzima bwacu.Kurugero, indege nazo zizuzura helium.Nubwo ubwinshi bwa helium buri hejuru cyane ugereranije na hydrogène, ubushobozi bwo guterura helium yuzuye imipira hamwe nindege ni 93% byumuyaga wa hydrogène hamwe nindege zifite ubunini bumwe, kandi nta tandukaniro ryinshi.

Byongeye kandi, helium yuzuye indege na ballon ntibishobora gufata umuriro cyangwa guturika, kandi bifite umutekano kuruta hydrogene.Mu 1915, Ubudage bwakoresheje bwa mbere helium nka gaze yo kuzuza indege.Niba helium ibuze, imipira yumvikana hamwe nicyogajuru gikoreshwa mugupima ikirere ntigishobora kuzamuka mukirere kugirango gikore.

Byongeye kandi, helium irashobora kandi gukoreshwa mukwenda wo kwibira, amatara ya neon, ibipimo byerekana umuvuduko mwinshi nibindi bintu, ndetse no mumifuka myinshi ipakira imifuka yagurishijwe kumasoko, nayo irimo helium nkeya.
