M'zaka zambiri za 80s ndi pambuyo pa zaka 90, mabuloni a haidrojeni anali ofunikira.Tsopano, mawonekedwe a ma baluni a haidrojeni salinso pazithunzi zamakatuni.Palinso mabuloni ambiri ofiira owoneka bwino okongoletsedwa ndi magetsi, omwe amakondedwa ndi achinyamata ambiri.
Komabe, mabuloni a haidrojeni ndi owopsa kwambiri.Hydrojeni ikakhala m'mlengalenga ndikusisita ndi zinthu zina kuti ipange magetsi osasunthika, kapena ikakumana ndi malawi otseguka, imakhala yosavuta kuphulika.Mu 2017, zidanenedwa kuti achinyamata anayi ku Nanjing adagula mabaluni ofiira asanu ndi limodzi pa intaneti, koma m'modzi mwa iwo mwangozi adamwaza zowala pamabaluni akusuta.Chifukwa cha zimenezi, mabuloni asanu ndi limodziwo anaphulika limodzi ndi lina, ndipo anthu angapo anawotchedwa kwambiri.Awiri a iwo analinso ndi matuza m'manja mwawo, ndipo kupsa kumaso kunafika Sitandade II.
Pofuna chitetezo, mtundu wina wa "helium balloon" wawonekera pamsika.Sichapafupi kuphulika ndi kuwotcha, ndipo ndi otetezeka kuposa baluni ya haidrojeni.
Chifukwa chiyani mumagwiritsa ntchito mabuloni a helium
Choyamba, tiyeni timvetsetse chifukwa chake helium imatha kupanga mabuloni kuwuluka.
Mipweya yodzazitsa wamba m'mabaluni ndi haidrojeni ndi helium.Chifukwa kachulukidwe ka mipweya iwiriyi ndi yotsika poyerekeza ndi mpweya, kuchuluka kwa haidrojeni ndi 0.09kg/m3, kuchulukitsitsa kwa helium ndi 0.18kg/m3, komanso kusachulukira kwa mpweya ndi 1.29kg/m3.Choncho, atatuwo akakumana, mpweya wokhuthala umawakweza m’mwamba pang’onopang’ono, ndipo baluniyo imayandama m’mwamba mosalekeza malinga ndi mmene zimakhalira.
M'malo mwake, pali mpweya wambiri womwe umakhala wocheperako kuposa mpweya, monga ammonia wokhala ndi mphamvu ya 0.77kg/m3.Komabe, chifukwa fungo la ammonia limakwiyitsa kwambiri, limatha kukhala adsorbed pakhungu la mucous mucosa ndi conjunctiva, zomwe zimayambitsa kukwiya komanso kutupa.Pazifukwa zachitetezo, ammonia sangathe kudzazidwa mu baluni.
Helium sikuti ndi yotsika kwambiri, komanso imakhala yovuta kuwotcha, motero yakhala yabwino kwambiri m'malo mwa haidrojeni.
Helium angagwiritsidwe ntchito osati, komanso ambiri.
Helium imagwiritsidwa ntchito kwambiri
Ngati mukuganiza kuti helium ingagwiritsidwe ntchito kudzaza mabuloni, mukulakwitsa.Ndipotu helium ili ndi zambiri kuposa izi pa ife.Komabe, helium sichabechabe.Ndizofunikira kwambiri m'makampani ankhondo, kafukufuku wasayansi, mafakitale ndi magawo ena ambiri.
Ikasungunula ndi kuwotcherera zitsulo, helium imatha kusiyanitsa mpweya, kotero ingagwiritsidwe ntchito kupanga malo oteteza kuti asatengeke ndi mankhwala pakati pa zinthu ndi mpweya.
Kuonjezera apo, helium imakhala ndi malo otsika kwambiri otentha ndipo ingagwiritsidwe ntchito ngati firiji.Helium yamadzimadzi imagwiritsidwa ntchito kwambiri ngati sing'anga yozizira komanso yoyeretsera ma reactor a atomiki.Nthawi yomweyo, itha kugwiritsidwanso ntchito ngati chilimbikitso komanso chilimbikitso chamafuta a rocket.Pafupifupi, NASA imagwiritsa ntchito mazana a mamiliyoni a ma cubic mapazi a helium chaka chilichonse pakufufuza kwasayansi.
Helium imagwiritsidwanso ntchito m'malo ambiri a moyo wathu.Mwachitsanzo, ma airship nawonso adzadzazidwa ndi helium.Ngakhale kachulukidwe ka helium ndi wapamwamba pang'ono kuposa wa haidrojeni, mphamvu yokweza ma baluni odzazidwa ndi helium ndi ma airship ndi 93% ya ma baluni a haidrojeni ndi ma airship okhala ndi voliyumu yofanana, ndipo palibe kusiyana kwakukulu.
Komanso, ndege zodzaza ndi helium ndi mabuloni sangathe kugwira moto kapena kuphulika, ndipo ndi otetezeka kwambiri kuposa haidrojeni.Mu 1915, Germany idagwiritsa ntchito helium koyamba ngati gasi kudzaza ndege.Ngati helium ikusowa, ma baluni olira komanso zoyenda zakuthambo zomwe zimagwiritsidwa ntchito poyeza nyengo sizingakweze kukwera mumlengalenga kuti zigwire ntchito.
Kuphatikiza apo, helium itha kugwiritsidwanso ntchito muzovala zodumphira pansi, nyali za neon, zisonyezo zapamwamba ndi zinthu zina, komanso m'matumba ambiri a tchipisi omwe amagulitsidwa pamsika, omwe amakhalanso ndi helium pang'ono.
