Heliumndi imodzi mwa mpweya wochepa womwe ndi wopepuka kuposa mpweya. Chofunika kwambiri, ndi yokhazikika, yopanda mtundu, yopanda fungo komanso yopanda vuto, kotero ndi chisankho chabwino kwambiri kuigwiritsa ntchito kuphulitsa mabaluni oyandama okha.

Tsopano helium nthawi zambiri imatchedwa "gas rare earth" kapena "golden gas".Heliumnthawi zambiri imaonedwa kuti ndi chinthu chokhacho chachilengedwe chosabwezeretsedwanso padziko lapansi. Mukamagwiritsa ntchito kwambiri, mumakhala ndi zochepa, ndipo chimagwiritsidwa ntchito m'njira zosiyanasiyana.

Ndiye funso losangalatsa ndilakuti, kodi helium imagwiritsidwa ntchito chiyani ndipo chifukwa chiyani siingabwezeretsedwenso?

Kodi helium ya dziko lapansi imachokera kuti?

HeliumIli pa nambala yachiwiri pa tebulo la zinthu zozungulira. Ndipotu, ndi chinthu chachiwiri chochuluka kwambiri m'chilengedwe chonse, chachiwiri pambuyo pa haidrojeni, koma helium ndi yosowa kwambiri padziko lapansi.

Izi zili choncho chifukwaheliamuIli ndi valence ya zero ndipo sichitapo kanthu pazochitika zonse zabwinobwino. Nthawi zambiri imapezeka mu mawonekedwe a helium (He) ndi mpweya wake wa isotope.

Nthawi yomweyo, chifukwa ndi yopepuka kwambiri, ikangowonekera pamwamba pa dziko lapansi ngati mpweya, imathawira mosavuta mumlengalenga m'malo mokhala padziko lapansi. Pambuyo pa zaka mazana ambiri zothawa, pali helium yochepa kwambiri yotsala Padziko Lapansi, koma kuchuluka kwa helium komwe kulipo pakadali pano kumatha kusungidwa pafupifupi magawo 5.2 pa miliyoni.

Izi zili choncho chifukwa chakuti lithosphere ya Dziko Lapansi ipitiliza kupangaheliamukuti apeze ndalama zomwe zatayika chifukwa cha kuthawa kwake. Monga tanenera kale, helium nthawi zambiri sichita zinthu za mankhwala, ndiye imapangidwa bwanji?

Helium yambiri padziko lapansi ndi yopangidwa ndi kuwonongeka kwa ma radiation, makamaka kuwonongeka kwa uranium ndi thorium. Iyi ndi njira yokhayo yopangira helium pakadali pano. Sitingathe kupanga helium mwa njira yopangira mankhwala. Helium yambiri yopangidwa ndi kuwonongeka kwachilengedwe imalowa mumlengalenga, kusunga kuchuluka kwa helium uku ikutayika nthawi zonse, koma ina yake idzatsekedwa ndi lithosphere. Helium yotsekedwayo nthawi zambiri imasakanizidwa ndi mpweya wachilengedwe, ndipo pamapeto pake imapangidwa ndikulekanitsidwa ndi anthu.

Kodi helium imagwiritsidwa ntchito pa chiyani?

Helium ili ndi kusungunuka kochepa kwambiri komanso kutentha kwake kumakhala kotsika kwambiri. Makhalidwe amenewa amalola kuti igwiritsidwe ntchito m'magawo ambiri, monga kuwotcherera, kupondereza ndi kuyeretsa, zomwe zonse zimakonda kugwiritsa ntchito helium.

Komabe, chomwe chimapangitsadiheliamu"Mpweya wagolide" ndiye malo ake otsika owira. Kutentha kofunikira ndi malo owira a helium yamadzimadzi ndi 5.20K ndi 4.125K motsatana, zomwe zili pafupi ndi zero yeniyeni komanso zotsika kwambiri pakati pa zinthu zonse.

Izi zimapangitsaheliamu yamadzimadziamagwiritsidwa ntchito kwambiri mu cryogenics ndi kuziziritsa kwa ma superconductors.

Zinthu zina zimawonetsa mphamvu ya superconductivity pa kutentha kwa nayitrogeni yamadzimadzi, koma zinthu zina zimafuna kutentha kochepa. Zimafunika kugwiritsa ntchito helium yamadzimadzi ndipo sizingasinthidwe. Mwachitsanzo, zipangizo zoyendetsera superconductor zomwe zimagwiritsidwa ntchito mu zida zojambulira zamaginito ndi European Large Hadron Collider zonse zimazizidwa ndi helium yamadzimadzi.

Kampani yathu ikuganiza zolowa mu gawo la helium yamadzimadzi, chonde khalani tcheru.
