I-Helium (Yena)

Imingcele Yezobuchwepheshe

I-Helium igesi eyivelakancane, igesi engenambala ekhanyayo, engenambala nengenaphunga. Ayisebenzi ngamakhemikhali, futhi kunzima ukusabela nezinye izinto ngaphansi kwezimo ezijwayelekile. Inezici zamakhemikhali ezinzile futhi iphuzi ngokumnyama uma ikhipha ugesi ophansi. I-Helium ingasetshenziswa njenge-ejenti ecindezelayo kanye ne-supercharger kuphethiloli we-rocket liquid, futhi isetshenziswa ngobuningi emicibisholo, imikhumbi-mkhathi kanye nezindiza eziphakeme kakhulu; njengegesi evikelayo ngesikhathi sokuncibilikiswa nokushiselwa, isetshenziswa ekwakheni imikhumbi, izindiza, imikhumbi-mkhathi, amarokhethi, kanye Ukwenziwa kwezikhali kubaluleke kakhulu; I-helium ikwazi ukungeneka kahle kakhulu futhi isetshenziselwa ukupholisa ama-reactors enuzi, kanye nokubona ukuvuza kwamarokhethi namapayipi ezinto eziphehla amandla enuzi kanye nezinto zikagesi nezikagesi; I-helium inobukhulu obuphansi nokuminyana kwesisindo, futhi Ayishi futhi ingasetshenziswa ukugcwalisa izibani namashubhu e-neon. Iphinde ibe igesi ekahle yamabhaluni nemikhumbi yomoya; I-helium ewuketshezi ingathola izinga lokushisa eliphansi eliseduze nezinga lokushisa eliphelele (-273°C) futhi isetshenziselwa ukwenza imishini ye-superconducting; I-helium iwuhlobo lwegesi ye-inert, Ukuncibilika kwegazi kuphansi kune-nitrogen, ngakho-ke i-anesthesia yayo iphansi kune-nitrogen. Ngakho-ke, i-helium nomoya-mpilo kuvame ukuxutshwa njengegesi yokuphefumula yabatshuzi. I-Helium kufanele igcinwe iqondile endaweni engenawo umoya, ephephile futhi engenaso isimo sezulu, futhi izinga lokushisa lokulondoloza akufanele libe ngaphezu kuka-52°C. Akufanele kube khona izinto ezivutha umlilo endaweni yokugcina futhi uqhelelane nezindawo zokungena nokuphuma njalo nezindawo zokuphuma eziphuthumayo, futhi kungabikho usawoti noma ezinye izinto ezigqwalayo. Kumasilinda egesi angasetshenzisiwe, i-valve cap kanye ne-valve yokuphuma kufanele ivalwe kahle, futhi amasilinda angenalutho kufanele agcinwe ngokuhlukana namasilinda agcwele. Gwema isitoreji esiningi kanye nesikhathi eside sokulondoloza, futhi ugcine amarekhodi amahle okulondoloza.

Isicelo:

1.Cryogenic Cooling Ukusetshenziswa:

Igesi ye-Helium esetshenziswa kakhulu esitimeleni se-maglev nakwemishini ye-imaging ye-Nuclear magnetic resonance (NMR) yezokwelapha.

2. Ukusetshenziswa kwebhaluni:

I-inflat yebhaluni yephathi yosuku lokuzalwa noma umgubho noma i-inflat ye-airship.

3.Hlola Ukuhlaziya:

Igesi ye-Helium esetshenziswa kakhulu ekutholeni ukuvuza kwe-vaccum njengesitholi sokuvuza se-helium mass spectrometer.

4.I-Shielding Gas:

I-Helium ivame ukusetshenziswa njenge-magnesium, i-zirconium ne-aluminium, i-titanium nezinye izinsimbi ezishisela igesi evikelayo.

Usayizi Wephakheji:

Izinzuzo:

1. Imboni yethu ikhiqiza i-Helium ngezinto ezingavuthiwe zekhwalithi ephezulu, ngaphandle kwentengo ishibhile.
2. I-Helium ikhiqizwa ngemva kwezinqubo zezikhathi eziningi zokuhlanzwa nokulungiswa embonini yethu.Isistimu yokulawula i-inthanethi iqinisekisa ubumsulwa begesi zonke izigaba.Umkhiqizo oqediwe kufanele uhlangabezane nezinga.
3. Ngesikhathi sokugcwalisa, i-cylinder kufanele yomiswe kuqala isikhathi eside (okungenani amahora angu-16), bese sihlanza isilinda, ekugcineni siyisusa ngegesi yasekuqaleni.Zonke lezi zindlela zenza isiqiniseko sokuthi igesi ihlanzekile ku-cylinder.
4. Sesibe khona emkhakheni weGesi iminyaka eminingi, isipiliyoni esicebile ekukhiqizeni nasekuthumeleni kwamanye amazwe masiwine amakhasimende' ukwethemba, banelisa ngenkonzo yethu futhi basinikeze ukuphawula okuhle.
