Helium (Yena)

Iiparamitha zobuGcisa

I-Helium yigesi enqabileyo, ukukhanya kakhulu, igesi engenambala kwaye engenavumba.Ayisebenzi kwiikhemikhali, kwaye kunzima ukusabela kunye nezinye izinto phantsi kweemeko eziqhelekileyo.Ineempawu zeekhemikhali ezizinzileyo kwaye imnyama tyheli xa ikhupha i-low-voltage discharge.I-Helium ingasetyenziswa njenge-arhente yoxinzelelo kunye ne-supercharger ye-rocket liquid fuel, kwaye isetyenziswe ngobuninzi kwimijukujelwa, i-spacecraft kunye neenqwelomoya eziphezulu;njengerhasi ekhuselayo ngexesha lokunyibilikiswa nokuwelda, isetyenziswa ekwakhiweni kweenqanawa, kwinqwelomoya, kwiziphekepheke, kwiirokethi, nakwi Ukwenziwa kwezixhobo kubaluleke kakhulu;I-helium inokungena okugqwesileyo kwaye isetyenziselwa ukupholisa izixhobo zenyukliya, kunye nokukhangela ukuvuza kwiirokethi kunye nemibhobho yezixhobo zenyukliya kunye nezixhobo zombane nezombane;I-helium inobunzima obuphantsi kunye nobunzima bobunzima, kwaye Ayinakutsha kwaye ingasetyenziselwa ukugcwalisa iibhalbhu zokukhanya kunye ne-neon tubes.Ikwayigesi efanelekileyo yeebhaluni kunye neenqwelomoya;I-helium engamanzi inokufumana ubushushu obuphantsi kufutshane nobushushu obupheleleyo (-273°C) kwaye isetyenziselwa ukwenza izixhobo ze-superconducting;I-helium luhlobo lwegesi ye-inert, I-solubility egazini iphantsi kune-nitrogen, ngoko ke i-anesthesia yayo iphantsi kune-nitrogen.Ke ngoko, i-helium kunye neoksijini zihlala zixutywa njengegesi yokuphefumla kwabo bahlukeneyo.I-Helium kufuneka igcinwe ime nkqo kwindawo engena moya, ekhuselekileyo nengenamozulu, kwaye ubushushu bokugcina akufunekanga bube ngaphezulu kwe 52°C.Akufunekanga kubekho izinto ezinokutsha kwindawo yokugcina kwaye ugcine kude kwiindawo zokungena nokuphuma rhoqo kunye neendawo zokuphuma ngokukhawuleza, kwaye kungabikho tyuwa okanye ezinye izinto ezidliwayo.Kwiisilinda zegesi ezingasetyenziswanga, i-valve cap kunye ne-valve yokuphuma kufuneka ivalwe kakuhle, kwaye iisilinda ezingenanto kufuneka zigcinwe ngokwahlukileyo kwiisilinda ezipheleleyo.Gwema ukugcinwa ngokugqithiseleyo kunye nexesha elide lokugcina, kwaye ugcine iirekhodi ezilungileyo zokugcina.

Isicelo:

1.Ukusetyenziswa kokupholisa kweCryogenic:

Irhasi yeHelium esetyenziswa kakhulu kuloliwe we-maglev kunye nezixhobo zonyango zeNyuclear magnetic resonance (NMR).

2.Ukusetyenziswa kwebhaluni:

I-inflat yebhaloni yetheko lokuzalwa okanye umbhiyozo okanye i-inflat ye-airship.

3.Jonga uHlahlelo:

Irhasi yeHelium isetyenziswa kakhulu ekubhaqweni kokuvuza kwe-vaccum njengesixhobo sokuvuza se-helium mass spectrometer.

4.IGesi yokuKhusela:

I-Helium isoloko isetyenziswa njenge-magnesium, i-zirconium kunye ne-aluminiyam, i-titanium kunye nezinye izinyithi zokuwelda igesi ekhuselayo.

Ubungakanani Bepakethe:

Izinto eziluncedo:

1. Umzi-mveliso wethu uvelisa i-Helium kwimathiriyeli ekrwada ekumgangatho ophezulu, ngaphandle kwexabiso eliphantsi.
2. I-Helium iveliswa emva kweenkqubo ezininzi zokuhlanjululwa kunye nokulungiswa kwifektri yethu.Inkqubo yokulawula i-intanethi iqinisekisa ukucoceka kwegesi yonke inqanaba.Imveliso egqityiweyo kufuneka ihlangabezane nomgangatho.
3. Ngethuba lokuzaliswa, i-cylinder kufuneka iqale yomiswe ixesha elide (ubuncinci i-16hrs), emva koko sicoce i-cylinder, ekugqibeleni siyikhuphe nge-gas yokuqala.Zonke ezi ndlela ziqinisekisa ukuba igesi ihlambulukile kwi-cylinder.
4. Sikhona kwintsimi yeGesi iminyaka emininzi, amava atyebileyo kwimveliso kunye nokuthumela ngaphandle masiphumelele abathengi' bathembe, bayanelisa ngenkonzo yethu kwaye basinike izimvo ezilungileyo.
