I-Helium 99.999% ubumsulwa He Electronic Gas

Umthombo oyinhloko we-helium imithombo yegesi yemvelo. Itholakala ngokusebenzisa i-liquefaction kanye nemisebenzi yokuhlubula.Ngenxa yokushoda kwe-helium emhlabeni, izicelo eziningi zinezinhlelo zokubuyisela kabusha i-helium.
I-Helium inezinhlelo zokusebenza ezibalulekile emkhakheni we-aerospace, njengegesi yokulethwa kanye ne-pressurization yama-rocket kanye ne-spacecraft propellants, futhi njenge-ejenti yokucindezela yezinhlelo zamanzi aphansi kanye nendiza. Ngenxa yokuminyana kwayo okuncane kanye nemvelo ezinzile, i-helium ivame ukusetshenziselwa ukugcwalisa amabhaluni okubuka isimo sezulu namabhaluni okuzijabulisa ukuze inikeze ukuphakamisa. I-Helium iphephile kune-hydrogen evuthayo ngoba ayishi noma ibangele ukuqhuma. I-liquid helium ingahlinzeka ngendawo yokushisa ephansi kakhulu ukuze isetshenziswe kubuchwepheshe be-superconducting kanye ne-magnetic resonance imaging (MRI), igcine izimo zokushisa eziphansi kakhulu ezidingekayo kuma-superconducting magnetic.

Emkhakheni wezokwelapha, i-helium isetshenziselwa ukugcina indawo ye-cryogenic yama-superconductors kumadivayisi we-magnetic resonance imaging kanye nokwelashwa okuhambisanayo njengokwesekwa kokuphefumula. I-Helium isebenza njengegesi evikelayo engasebenzi ukuze ivimbele ukusabela kwe-oxidation ngesikhathi sokushisela futhi isetshenziselwa ukuthola igesi kanye nobuchwepheshe bokubona ukuvuza ukuze kuqinisekiswe ukucinana kwemishini namasistimu. Ocwaningweni lwesayensi nasemalabhorethri, i-helium ivame ukusetshenziswa njengegesi ethwala i-chromatography yegesi, ihlinzeka ngendawo yokuhlola ezinzile. Enqubweni yokukhiqiza i-semiconductor, i-helium isetshenziselwa ukupholisa nokudala indawo ehlanzekile, iqinisekisa ukuzinza kwenqubo yokukhiqiza kanye nekhwalithi yomkhiqizo.

Imiyalo yokuphepha

Uhlolojikelele oluphuthumayo: Ayikho igesi, isitsha sesilinda kulula ukusicindezela ngaphansi kokushisa, kunengozi yokuqhuma.
I-GHS Hazard Category: Ngokohlelo Lwekhemikhali, Ilebula Yesexwayiso kanye Nochungechunge Lwezicaciso Zesexwayiso, lo mkhiqizo uyigesi engaphansi kwengcindezi - igesi ecindezelwe.
Igama lesixwayiso: Isexwayiso
Ulwazi lwengozi: Igesi ngaphansi kwengcindezi, uma ukushisisa kungaqhuma.
Izinyathelo zokuzivikela:
Izexwayiso: Zigcine kude nemithombo yokushisa, amalangabi avulekile, nezindawo ezishisayo. Akukho ukubhema emsebenzini.
Ukusabela ngengozi: nqamula umthombo ovuzayo, ngenisa umoya ofanele, sheshisa ukusabalalisa.
Ukugcina okuphephile: Gwema ukukhanya kwelanga, gcina endaweni enomoya omuhle Ukulahlwa kwemfucuza: Lo mkhiqizo noma isitsha sawo kufanele ulahlwe ngokuhambisana nemithetho yendawo.
Izingozi ezingokomzimba namakhemikhali: igesi elicindezelweyo elingashi, isitsha sesilinda kulula ukusicindezela kakhulu lapho sishiswa, futhi kunengozi yokuqhuma. Ukuhogela okugxilile kakhulu kungabangela ukuminza. Ukuchayeka ku-helium ewuketshezi kungabangela isithwathwa.
Ingozi yezempilo: Lo mkhiqizo uyigesi engasebenzi, ukugxila okuphezulu kunganciphisa ukucindezela okuncane futhi kube nobungozi bokuminyanisa. Lapho ukugcwala kwe-helium emoyeni kwanda, isiguli siqala ukuphefumula ngokushesha, ukunganaki, kanye ne-ataxia, kulandele ukukhathala, ukucasuka, isicanucanu, ukuhlanza, ukukhohlakala, ukudlikizela, nokufa.
Ukulimala kwemvelo: Akukho monakalo emvelweni.
