Helium 99.999% kuchena Iye Electronic Gasi

Nzvimbo huru yehelium matsime egasi chaiwo. Inowanikwa kuburikidza nekuita liquefaction uye kubvisa mabasa.Nekuda kwekushomeka kwehelium munyika, maapplication mazhinji ane masisitimu ekudzoreredza kuti adzore helium.
Helium ine zvakakosha mashandisirwo muchikamu chemuchadenga, sekutumira uye kudzvanya gasi reroketi uye spacecraft propellants, uye semumiririri wepressurization yepasi uye ndege fluid masisitimu. Nekuda kwehudiki hwayo uye yakagadzikana hunhu, helium inowanzoshandiswa kuzadza mabharuni ekutarisa mamiriro ekunze uye mabharumu evaraidzo kupa kusimudza. Helium yakachengeteka kudarika haidrojeni inobvira nekuti haipisi kana kukonzera kuputika. Liquid helium inogona kupa yakadzika kwazvo tembiricha nharaunda kuti ishandiswe mune superconducting tekinoroji uye magineti resonance imaging (MRI), kuchengetedza yakanyanya kuderera tembiricha inodiwa kune superconducting magineti.

Munzvimbo yezvokurapa, helium inoshandiswa kuchengetedza cryogenic nharaunda ye superconductors mune magineti resonance imaging zvishandiso uye nekuwedzera marapirwo akadai sekufema kutsigirwa. Helium inoshanda senge inert inodzivirira gasi kudzivirira oxidation maitiro panguva yewelding uye inoshandiswawo mukuonekwa kwegasi uye tekinoroji yekuona inodonha kuve nechokwadi kusimba kwemidziyo nemasisitimu. Mukutsvagisa kwesainzi uye marabhoritari, helium inowanzoshandiswa semutakuri gasi kune gasi chromatography, ichipa yakagadzikana nharaunda yekuyedza. Mune semiconductor yekugadzira maitiro, helium inoshandiswa kutonhora uye kugadzira nzvimbo yakachena, kuve nechokwadi kugadzikana kwemaitiro ekugadzira uye mhando yechigadzirwa.

Mirayiridzo Yekuchengetedza

Emergency overview: Hapana gasi, iyo silinda mudziyo iri nyore kudzvinyirira pasi pekupisa, kune njodzi yekuputika.
GHS Hazard Category: Zvinoenderana neChemical Classification, Yambiro Label uye Warning Specification series, chigadzirwa ichi igasi riri pasi pekumanikidzwa - yakamanikidzwa gasi.
Yambiro izwi: Yambiro
Njodzi ruzivo: Gasi pasi pekumanikidzwa, kana inopisa inogona kuputika.
Zvekungwaririra:
Chengetedzo: Chengetedza kure nenzvimbo dzekupisa, marimi akavhurika, uye nzvimbo dzinopisa. Hapana kuputa kumabasa.
Mhinduro yetsaona: cheka kwainobvinza, kufefetedza kwakanaka, mhanyisa kupararira.
Kuchengetera kwakachengeteka: Dzivisa chiedza chezuva, chengeta munzvimbo ine mhepo inofefetera Kurasa tsvina: Chigadzirwa ichi kana chigaba chacho chicharaswa zvichitevedza mirau yenzvimbo.
Njodzi dzemuviri uye dzemakemikari: gasi rakamanikidzwa risingabatike, chigadziko checylinder chiri nyore kudzvinyirira kana ichipisa, uye kune njodzi yekuputika. Kufuridzira kwakanyanya kunogona kukonzera kudzipwa. Kusangana nemvura helium kunogona kukonzera chando.
Njodzi yehutano: Ichi chigadzirwa igesi inert, kuwanda kwakanyanya kunogona kuderedza kudzvinyirira uye kuve nengozi yekukachidza. Kana huwandu hwehelium mumhepo huchiwedzera, murwere anotanga kufema nekukurumidza, kusava nehanya, uye ataxia, zvichiteverwa nekuneta, kugumbuka, kusvotwa, kurutsa, coma, kugwinha, uye kufa.
Kukuvadza kwezvakatipoteredza: Hapana kukuvadza kune zvakatipoteredza.
