Heliumndi imodzi mwa mipweya yochepa yomwe imakhala yopepuka kuposa mpweya. Chofunika koposa, ndi chokhazikika, chopanda mtundu, chopanda fungo komanso chosavulaza, kotero ndi chisankho chabwino kwambiri kuchigwiritsa ntchito pophulitsa mabuloni oyandama.

Tsopano helium nthawi zambiri amatchedwa "gasi osowa padziko lapansi" kapena "gesi wagolide".Heliumnthawi zambiri amaonedwa kuti ndi chilengedwe chokhacho chomwe sichingawonjezeke pa Dziko Lapansi. Mukamagwiritsa ntchito kwambiri, mumakhala ndi zochepa, ndipo zimakhala ndi ntchito zambiri.

Kotero, funso lochititsa chidwi ndiloti, kodi helium imagwiritsidwa ntchito bwanji ndipo n'chifukwa chiyani ndi yosasinthika?

Kodi helium ya padziko lapansi imachokera kuti?

Heliumali wachiwiri pa tebulo la periodic. Ndipotu, ilinso chinthu chachiwiri chochuluka kwambiri m'chilengedwe chonse, chachiwiri kwa haidrojeni, koma helium ndiyosowa kwambiri padziko lapansi.

Izi ndichifukwaheliumali ndi valence ya ziro ndipo samakumana ndi zochitika za mankhwala pansi pazochitika zonse. Nthawi zambiri amangokhala ngati helium (He) ndi mpweya wake wa isotope.

Panthawi imodzimodziyo, chifukwa ndi yopepuka kwambiri, ikangowonekera padziko lapansi mu mawonekedwe a mpweya, idzathawa mosavuta mumlengalenga m'malo mokhala padziko lapansi. Pambuyo pa kuthawa kwazaka mazana mamiliyoni ambiri, padziko lapansi patsala helium yochepa, koma helium yomwe ilipo panopa mumlengalenga ikhoza kusungidwa pafupifupi magawo 5.2 pa milioni.

Izi zili choncho chifukwa lithosphere ya Dziko lapansi idzapitiriza kupangaheliumkuti abwezeretse kutayika kwake. Monga tanenera kale, helium nthawi zambiri simakhudzidwa ndi mankhwala, ndiye amapangidwa bwanji?

Zambiri mwa helium Padziko Lapansi ndizopangidwa ndi kuwonongeka kwa radioactive, makamaka kuwonongeka kwa uranium ndi thorium. Iyinso ndi njira yokhayo yopangira helium pakadali pano. Sitingathe kupanga helium mwachisawawa pogwiritsa ntchito mankhwala. Zambiri mwa helium zopangidwa ndi kuwonongeka kwachilengedwe zidzalowa mumlengalenga, kusunga ndende ya helium pamene ikutayika mosalekeza, koma zina zidzatsekedwa ndi lithosphere. Helium yotsekedwa nthawi zambiri imasakanizidwa ndi gasi, ndipo pamapeto pake imapangidwa ndikulekanitsidwa ndi anthu.

Kodi helium imagwiritsidwa ntchito bwanji?

Helium ili ndi kusungunuka kochepa kwambiri komanso kutsika kwambiri kwamafuta. Makhalidwewa amalola kuti agwiritsidwe ntchito m'madera ambiri, monga kuwotcherera, kuponderezedwa ndi kuyeretsa, zomwe zonse zimakonda kugwiritsa ntchito helium.

Komabe, zomwe zimapangitsa kwenikwenihelium"Golden gas" ndi malo ake owira pang'ono. Kutentha kwambiri ndi kuwira kwa helium yamadzimadzi ndi 5.20K ndi 4.125K motsatira, zomwe zili pafupi ndi ziro komanso zotsika kwambiri pakati pa zinthu zonse.

Izi zimapangitsamadzi heliumamagwiritsidwa ntchito kwambiri mu cryogenics ndi kuziziritsa kwa superconductors.

Zinthu zina zimawonetsa superconductivity pakutentha kwa nayitrogeni wamadzimadzi, koma zinthu zina zimafunikira kutentha kochepa. Ayenera kugwiritsa ntchito helium yamadzimadzi ndipo sangathe kusinthidwa. Mwachitsanzo, zida za superconducting zomwe zimagwiritsidwa ntchito pazida zamaginito zamaginito ndi European Large Hadron Collider zonse zimaziziritsidwa ndi helium yamadzi.

Kampani yathu ikuganiza zolowa m'munda wamadzimadzi a helium, chonde khalani tcheru.
