I-Helium isetshenziswa kakhulu, Kungani kufanele usebenzise amabhaluni e-helium?

Ebuntwaneni abaningi bangemva ko-80s nangemuva kweminyaka yama-90, amabhaluni e-hydrogen ayebaluleke kakhulu.Manje, ukwakheka kwamabhaluni e-hydrogen akusakhawulelwe kumaphethini opopayi.Kukhona namabhaluni amaningi anetha abomvu akhanyayo ahlotshiswe ngamalambu, athandwa yintsha eningi.

Nokho, amabhaluni e-hydrogen ayingozi kakhulu.Uma i-hydrogen isisemoyeni futhi isihlikihla nezinye izinto ukuze ikhiqize ugesi ongashintshi, noma ihlangana namalangabi avulekile, kulula ukuqhuma.Ngo-2017, kwabikwa ukuthi abantu abasha abane eNanjing bathenga amabhaluni abomvu ayisithupha aku-inthanethi, kodwa oyedwa wabo wachaphaza ngephutha izinhlansi kumabhaluni ngenkathi ebhema.Ngenxa yalokho, amabhaluni ayisithupha aqhuma ngokulandelana, abangela ukuba abantu abambalwa bashiswe kabi.Ababili kubo babenamabhamuza ezandleni, futhi ukusha ebusweni kwafinyelela eBangeni II.

Ukuze kuphephe, sekuvele olunye uhlobo "lwebhaluni le-helium" emakethe.Akulula ukuqhuma nokushiswa, futhi iphephile kunebhaluni le-hydrogen.

Kungani usebenzise amabhaluni e-helium

Ake siqale siqonde ukuthi kungani i-helium ingenza amabhaluni andize.

Amagesi okugcwalisa ajwayelekile kumabhaluni i-hydrogen ne-helium.Ngenxa yokuthi ukuminyana kwala magesi amabili kuphansi kunomoya, ukuminyana kwe-hydrogen ngu-0.09kg/m3, ukuminyana kwe-helium ngu-0.18kg/m3, kanti ukuminyana komoya kungu-1.29kg/m3.Ngakho-ke, lapho laba bobathathu behlangana, umoya ominyene uzowaphakamisa kancane, futhi ibhaluni liyontanta liye phezulu ngokuqhubekayo kuye ngokuthi liyanyakaza kangakanani.

Eqinisweni, kunamagesi amaningi anomthamo ophansi kunomoya, njenge-ammonia enomthamo ongu-0.77kg/m3.Kodwa-ke, ngenxa yokuthi iphunga le-ammonia liyacasula kakhulu, lingakhangiswa kalula ku-mucosa yesikhumba kanye ne-conjunctiva, okubangela ukucasuka nokuvuvukala.Ngenxa yezizathu zokuphepha, i-ammonia ayikwazi ukugcwaliswa ebhaluni.

I-Helium ayigcini nje ngokuminyana, kodwa futhi inzima ukuyishisa, ngakho isibe indawo engcono kakhulu ye-hydrogen.

I-Helium ingasetshenziswa hhayi kuphela, kodwa futhi kabanzi.

I-Helium isetshenziswa kabanzi

Uma ucabanga ukuthi i-helium ingasetshenziswa kuphela ukugcwalisa amabhaluni, unephutha.Eqinisweni, i-helium inokuningi kunale miphumela kithi.Nokho, i-helium ayisizi ngalutho.Kubaluleke kakhulu embonini yezempi, ucwaningo lwesayensi, imboni kanye neminye imikhakha eminingi.

Lapho kuncibilika futhi kushiselwa insimbi, i-helium ingahlukanisa umoya-mpilo, ngakho-ke ingasetshenziswa ukwakha indawo evikelayo ukuze kugwenywe ukusabela kwamakhemikhali phakathi kwezinto nomoya-mpilo.

Ngaphezu kwalokho, i-helium inephuzu lokubilisa eliphansi kakhulu futhi ingasetshenziswa njengesiqandisi.I-helium ewuketshezi isetshenziswa kakhulu njengendawo yokupholisa kanye ne-ejenti yokuhlanza yama-athomu asabelayo.Ngesikhathi esifanayo, ingasetshenziswa futhi njenge-booster kanye ne-booster ye-liquid rocket fuel.Ngokwesilinganiso, i-NASA isebenzisa amakhulu ezigidi zama-cubic feet we-helium njalo ngonyaka ocwaningweni lwesayensi.

I-Helium isetshenziswa futhi ezindaweni eziningi zokuphila kwethu.Isibonelo, izindiza zezindiza nazo zizogcwaliswa nge-helium.Nakuba ukuminyana kwe-helium kungaphezudlwana kwe-hydrogen, amandla okuphakamisa amabhaluni agcwele i-helium nemikhumbi yomoya angama-93% amabhaluni e-hydrogen nemikhumbi yomoya enevolumu efanayo, futhi awukho umehluko omkhulu.

Ngaphezu kwalokho, izindiza ezigcwele i-helium namabhaluni awakwazi ukubamba umlilo noma ukuqhuma, futhi aphephe kakhulu kune-hydrogen.Ngo-1915, iJalimane yaqala ukusebenzisa i-helium njengegesi ukugcwalisa izindiza.Uma i-helium ingekho, amabhaluni anomsindo nemikhumbi-mkhathi esetshenziselwa ukukala isimo sezulu ingase ingakwazi ukukhuphukela emoyeni ukuze isebenze.

Ngaphezu kwalokho, i-helium ingasetshenziswa futhi kumasudi okuntywila, izibani ze-neon, izinkomba zokucindezela okukhulu nezinye izinto, kanye nasezikhwameni eziningi zokupakisha zama-chips athengiswa emakethe, aqukethe inani elincane le-helium.
