Chii ichi chinyorwa?
Helium igasi risina ruvara, risinganhuhwi, risingaravi iro rakareruka kupfuura mweya. Mumamiriro ayo echisikigo, helium inowanzovapo mune zvidiki mumhepo yePasi segasi. Zvisinei, inonyanya kutorwa kubva mumatsime egasi chaiwo, uko inowanikwa munzvimbo dzakakwirira.
Ndekupi kushandisa zvinhu izvi?
Mabharumu eKutandara: Helium inonyanya kushandiswa kufuridzira mabharumu, achiita kuti ayangamire mumhepo. Iyi isarudzo yakakurumbira yemhemberero, mapato uye zviitiko.
Mabharuni eMamiriro ekunze: Mabharuni emamiriro ekunze akazadzwa neHelium anoshandiswa kuunganidza data remuchadenga mune zvidzidzo zvemamiriro ekunze uye mamiriro ekunze. Ziva kuti mashandisirwo chaiwo uye mirau yekushandiswa kwehelium inogona kusiyana nenyika, indasitiri uye chinangwa.
Zvikepe zvendege: Iyo yakareruka-kupfuura-mhepo zvimiro zvehelium inoita kuti ive yakakodzera kusimudza ngarava uye dhirigibles. Mota idzi dzinowanzo shandiswa mukushambadzira, kutora mafoto emuchadenga netsvagiridzo yesainzi.
Cryogenics: Helium inoshandiswa sechinhu chinotonhorera mu cryogenic systems. Iyo ine basa rekuchengeta tsvakiridzo yesainzi, michina yekufungidzira yekurapa (senge MRI scanners) uye superconducting magineti kutonhora.
Welding: Helium inowanzoshandiswa sekudzivirira gasi mune arc welding maitiro akadai tungsten inert gas (TIG). Inobatsira kuchengetedza nzvimbo yewelding kubva kumagasi emuchadenga uye inovandudza weld mhando.
Leak Detection: Helium inoshandiswa setracer gasi kuona kubuda mumasisitimu akasiyana senge pombi, maHVAC masisitimu, uye midziyo yefiriji. Helium leak detectors inoshandiswa kuona nemazvo uye kutsvaga kuvuza.
Kufema musanganiswa: Vanosiyana-siyana nevanoona nezvemuchadenga vanogona kushandisa heliox musanganiswa, senge heliox uye trimix, kuti vadzivise mhedzisiro yakaipa yekufema-kudzvanywa mhepo pakadzika kana munzvimbo.
Tsvagiridzo yeSainzi: Helium inoshandiswa mune dzakasiyana siyana kuyedza uye mashandisirwo ekutsvagisa, kusanganisira cryogenics, kuyedza zvinhu, nuclear magnetic resonance (NMR) spectroscopy, uye semutakuri gasi mugasi chromatography.
Ziva kuti mashandisirwo chaiwo uye mirau yekushandiswa kwechinhu ichi / chigadzirwa chinogona kusiyana nenyika, indasitiri uye chinangwa. Gara uchitevera mirairo yekuchengetedza uye bvunza nyanzvi usati washandisa chinhu ichi / chigadzirwa mune chero application.
