Helium 99.999% ubunyulu Yena Electronic Gas

Umthombo oyintloko we-helium yimithombo yegesi yendalo. Ifunyenwe ngokusebenzisa i-liquefaction kunye ne-stripping operations.Ngenxa yokunqongophala kwe-helium kwihlabathi, izicelo ezininzi zineenkqubo zokubuyisela ukubuyisela i-helium.
I-Helium inezicelo ezibalulekileyo kwicandelo le-aerospace, njengokuhanjiswa kunye negesi yoxinzelelo kwi-rocket kunye ne-spacecraft propellants, kunye ne-agent agent ye-pressurization ye-ground and flight fluid systems. Ngenxa yobuninzi bayo obuncinci kunye nendalo ezinzileyo, i-helium isoloko isetyenziselwa ukuzalisa iibhaluni zokuphonononga imozulu kunye neebhaluni zokuzonwabisa ukubonelela ngokuphakamisa. I-Helium ikhuselekile kune-hydrogen enokutsha ngenxa yokuba ayitshisi okanye ibangele ugqabhuko-dubulo. I-helium yolwelo inokubonelela ngemekobume yobushushu obuphantsi kakhulu ukuze isetyenziswe kubuchwephesha be-superconducting kunye ne-imaging resonance magnetic (MRI), ukugcina iimeko zobushushu eziphantsi kakhulu ezifunekayo kwiimagnethi ezinkulu.

Kwicandelo lezonyango, i-helium isetyenziselwa ukugcina indawo ye-cryogenic ye-superconductors kwizixhobo zokucinga ze-magnetic resonance imaging kunye nonyango olongezelelweyo olufana nenkxaso yokuphefumula. I-Helium isebenza njengegesi ekhuselayo engasebenziyo ukukhusela ukuphendula kwe-oxidation ngexesha le-welding kwaye isetyenziselwa ukukhangela igesi kunye nobuchwepheshe bokubona ukuvuza ukuze kuqinisekiswe ukuqina kwezixhobo kunye neenkqubo. Kuphando lwezenzululwazi kunye neebhubhoratri, i-helium isoloko isetyenziswa njengegesi ethwala i-chromatography yegesi, ibonelela ngendawo yovavanyo oluzinzileyo. Kwinkqubo yokuvelisa i-semiconductor, i-helium isetyenziselwa ukupholisa kunye nokudala indawo ecocekileyo, iqinisekisa ukuzinza kwenkqubo yokuvelisa kunye nomgangatho wemveliso.

Imiyalelo yoKhuseleko

Uphononongo olungxamisekileyo: Akukho rhasi, isikhongozeli se-cylinder silula ukucinezela phantsi kobushushu, kukho umngcipheko wokuqhuma.
I-GHS Hazard Category: Ngokutsho koHlelo lweMichiza, iLeyibhile yeSilumkiso kunye neNgcaciso yeSilumkiso, le mveliso yigesi ephantsi koxinzelelo - igesi ecinezelweyo.
Igama lesilumkiso: Isilumkiso
Ulwazi ngengozi: Igesi phantsi koxinzelelo, ukuba ubushushu bunokuqhuma.
Ukulumkela:
Izilumkiso: Zigcine kude nemithombo yobushushu, amadangatye avulekileyo, kunye neendawo ezishushu. Akutshaywa emsebenzini.
Impendulo ngengozi: Sika umthombo wokuvuza, ukungena komoya okufanelekileyo, ukukhawulezisa ukusasaza.
Ugcino olukhuselekileyo: Kuphephe ukukhanya kwelanga, gcina kwindawo enomoya owaneleyo.
Ubungozi bomzimba kunye neekhemikhali: igesi ecinezelweyo engatshiyo, isitya se-cylinder silula ukuxinzelela xa sishushu, kwaye kukho umngcipheko wokuqhuma. Ukuphefumla okugxininise kakhulu kunokubangela ukuphefumla. Ukuvezwa kwi-helium engamanzi kunokubangela iqabaka.
Ingozi yempilo: Le mveliso yigesi engasebenziyo, ukugxila okuphezulu kunokunciphisa uxinzelelo oluncinci kwaye kube nobungozi bokuminxa. Xa ukuxinana kwe-helium emoyeni kunyuka, isigulane siqala ukuphefumla ngokukhawuleza, ukungakhathaleli, kunye ne-ataxia, kulandelwa kukudinwa, ukucaphuka, isicaphucaphu, ukuhlanza, isiqaqa, ukuxhuzula nokufa.
Ukwenzakala kokusingqongileyo: Akukho bungozi kokusingqongileyo.
