I-nitrogen (N2)

Iiparamitha zobugcisa

I-Nitrojeni (N2) yenza eyona nxalenye ingundoqo yeatmosfera yomhlaba, ibalelwa kuma-78.08% ewonke.Yigesi engenambala, ayinavumba, ayinancasa, ayinatyhefu kwaye iphantse ibe yigesi engasebenziyo ngokupheleleyo.I-nitrojeni ayinakutsha kwaye ithathwa njengegesi efunxayo (oko kukuthi, ukuphefumla i-nitrogen ecocekileyo kuya kuhlutha umzimba womntu oksijini).I-nitrogen ayisebenzi kwiikhemikhali.Iyakwazi ukusabela nge-hydrogen ukwenza i-ammonia phantsi kobushushu obuphezulu, uxinzelelo oluphezulu kunye neemeko ze-catalyst;inokudibanisa neoksijini ukwenza i-nitric oxide phantsi kweemeko zokukhutshwa.I-nitrogen idla ngokubizwa ngokuba yigesi engasebenziyo.Isetyenziswe kwi-atmospheres ye-inert ethile yonyango lwetsimbi kunye nakwii-bulbs ukukhusela i-arcing, kodwa ayiyi-inert ye-chemically.Yinto ebalulekileyo kubomi bezityalo nezilwanyana, kwaye iyinxalenye yezinto ezininzi eziluncedo.I-nitrojeni idibanisa neentsimbi ezininzi ukwenza i-nitrides eqinile, enokusetyenziswa njengeentsimbi ezikwaziyo ukunxiba.Inani elincinci le-nitrogen kwintsimbi liya kuthintela ukukhula kweenkozo kumaqondo aphezulu kwaye liya kwandisa amandla eentsimbi ezithile.Ingasetyenziselwa ukuvelisa iindawo ezinzima kwintsimbi.I-nitrogen ingasetyenziselwa ukwenza i-ammonia, i-nitric acid, i-nitrate, i-cyanide, njl.ekwenzeni iziqhushumbisi;ukuzalisa i-thermometers yobushushu obuphezulu, ii-incandescent bulbs;ukwenza izinto ze-inert zokugcina izinto, ezisetyenziselwa kwiibhokisi zokumisa okanye iingxowa zeglavu.Ulwelo lwenitrogen ngexesha lokukhenkceza kokutya;isetyenziswe njengesipholisi kwilabhoratri.I-nitrogen kufuneka igcinwe nkqo kwindawo engenamoya, 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:

①Kwizixhobo ezahlukeneyo zohlalutyo:

Irhasi ye-Carrier ye-chromatography yegesi, igesi yenkxaso ye-Electron Capture Detectors, i-Liquid Chromatography Mass Spectrometry, i-gas yokucoca i-Inductive Couple Plasma.

② Izinto:

1. Ukuzalisa iibhalbhu zokukhanya.
2. Kwi-atmospheric ye-antibacterial kunye nemixube yesixhobo sokusetyenziswa kwezinto eziphilayo .
3. Njengecandelo kwi-Controlled Atmosphere Packaging and Modified Atmosphere Packaging applications, 4. Imixube yerhasi yokulinganisa kwiinkqubo zokubeka iliso kokusingqongileyo, imixube yegesi yelaser.
5. Ukungenisa iikhemikhali ezininzi zomisa iimveliso ezahlukeneyo okanye imathiriyeli.

③Nitrojeni elulwelo:

Njengomkhenkce owomileyo, ukusetyenziswa okuphambili kwenitrogen engamanzi kufana nefriji.

Iphakheji eqhelekileyo:

I-advanteji:

① Ngaphezu kweminyaka elishumi kwimarike;

②ISO umenzi wesatifikethi;

③Ukuhanjiswa ngokukhawuleza;

④Umthombo wemathiriyeli ekrwada;

⑤Inkqubo yokuhlalutya kwi-intanethi yokulawula umgangatho kwinqanaba ngalinye;

⑥Imfuno ephezulu kunye nenkqubo enobuchule yokuphatha isilinda ngaphambi kokuzaliswa;
