Helium (Iye)

Magawo aukadaulo

Helium ndi mpweya wosowa, wopepuka kwambiri, wopanda mtundu komanso wopanda fungo. Sigwira ntchito ndi mankhwala, ndipo zimakhala zovuta kuchitapo kanthu ndi zinthu zina pansi pa mikhalidwe yabwinobwino. Ili ndi mphamvu zokhazikika za mankhwala ndipo imakhala yachikasu chakuda ikatulutsa mphamvu zochepa. Helium ingagwiritsidwe ntchito ngati choponderezera komanso chowonjezera mphamvu ya mafuta a roketi, ndipo imagwiritsidwa ntchito kwambiri m'mabomba, zombo zam'mlengalenga ndi ndege za supersonic; ngati mpweya woteteza panthawi yosungunulira ndi kuwotcherera, imagwiritsidwa ntchito popanga zombo, ndege, zombo zam'mlengalenga, zombo zam'mlengalenga, zombo zam'mlengalenga, ndi kupanga zida ndikofunikira kwambiri; helium ili ndi mphamvu yabwino kwambiri yolowera ndipo imagwiritsidwa ntchito kuziziritsa ma reactor a nyukiliya, komanso kuzindikira kutuluka kwa ma rocket ndi mapaipi a ma reactor a nyukiliya ndi zida zamagetsi ndi zamagetsi; helium ili ndi mphamvu yochepa komanso kulemera kochepa, ndipo siingayaka ndipo ingagwiritsidwe ntchito kudzaza mababu amagetsi ndi machubu a neon. Ndi mpweya wabwino kwambiri wa mabaluni ndi zombo zamlengalenga; helium yamadzi imatha kutentha pang'ono pafupi ndi kutentha konse (-273°C) ndipo imagwiritsidwa ntchito kupanga zida zowongolera mphamvu; Helium ndi mtundu wa mpweya wopanda mpweya, Kusungunuka m'magazi kumakhala kotsika kuposa kwa nayitrogeni, kotero mankhwala ake oletsa kupweteka ndi otsika kuposa a nayitrogeni. Chifukwa chake, helium ndi mpweya nthawi zambiri zimasakanizidwa ngati mpweya wopumira kwa osambira. Helium iyenera kusungidwa moyimirira pamalo opumira bwino, otetezeka komanso opanda nyengo, ndipo kutentha kosungirako sikuyenera kupitirira 52°C. Sipayenera kukhala zinthu zoyaka moto m'malo osungiramo ndipo sungani kutali ndi malo olowera ndi kutuluka pafupipafupi komanso malo otulukira mwadzidzidzi, ndipo palibe mchere kapena zinthu zina zowononga. Pa masilinda a gasi osagwiritsidwa ntchito, chivundikiro cha valavu ndi valavu yotulutsa ziyenera kutsekedwa bwino, ndipo masilinda opanda kanthu ayenera kusungidwa padera ndi masilinda athunthu. Pewani kusungirako mopitirira muyeso komanso nthawi yayitali yosungiramo, ndipo sungani zolemba zabwino zosungiramo.

Ntchito:

1. Kugwiritsa Ntchito Kuziziritsa kwa Cryogenic:

Mpweya wa helium umagwiritsidwa ntchito kwambiri mu sitima ya maglev ndi zida zamankhwala zojambulira za Nuclear magnetic resonance (NMR).

2. Kugwiritsa Ntchito Baluni:

Ikani baluni pa phwando la kubadwa kapena chikondwerero kapena ikani baluni pa ndege.

3. Kusanthula kwa Chongani:

Mpweya wa helium umagwiritsidwa ntchito kwambiri pozindikira kutuluka kwa vaccum monga chowunikira kutuluka kwa helium mass spectrometer.

4. Gasi Woteteza:

Helium nthawi zambiri imagwiritsidwa ntchito ngati magnesium, zirconium ndi aluminiyamu, titaniyamu ndi zitsulo zina zowotcherera mpweya woteteza.

Kukula kwa Phukusi:

Ubwino:

1. Fakitale yathu imapanga Helium kuchokera ku zinthu zopangira zapamwamba kwambiri, kupatulapo mtengo wake ndi wotsika mtengo.
2. Helium imapangidwa pambuyo pa njira zambiri zoyeretsera ndi kukonza mu fakitale yathu. Dongosolo lowongolera pa intaneti limaonetsetsa kuti mpweya umakhala woyera pagawo lililonse. Chogulitsa chomalizidwa chiyenera kukwaniritsa muyezo.
3. Pakudzaza, silinda iyenera kuuma kaye kwa nthawi yayitali (osachepera maola 16), kenako timatsuka silindayo ndi vacuum, kenako timaiyika ndi mpweya woyambirira. Njira zonsezi zimatsimikizira kuti mpweya uli woyera mu silindayo.
4. Takhalapo m'munda wa Gasi kwa zaka zambiri, chidziwitso chochuluka pakupanga ndi kutumiza kunja chimatithandiza kupeza makasitomala' Amatidalira, amakhutitsidwa ndi ntchito yathu ndipo amatipatsa ndemanga zabwino.
