I-nitrogen (N2)

Iiparameter zobugcisa

I-nitrogen (N2) yenza inxalenye ephambili yomoya womhlaba, ithatha i-78.08% yento yonke. Yigesi engenambala, engenavumba, engenancasa, engenatyhefu kwaye phantse ayinabungozi ngokupheleleyo. I-nitrogen ayitshi kwaye ithathwa njengegesi efunxayo (oko kukuthi, ukuphefumla i-nitrogen ecocekileyo kuya kuncitshisa umzimba womntu i-oxygen). I-nitrogen ayisebenzi ngamakhemikhali. Ingasabela ne-hydrogen ukwenza i-ammonia phantsi kobushushu obuphezulu, uxinzelelo oluphezulu kunye neemeko ze-catalyst; ingadibana ne-oxygen ukwenza i-nitric oxide phantsi kweemeko zokukhupha. I-nitrogen idla ngokubizwa ngokuba yi-gas engasebenziyo. Isetyenziswa kwiindawo ezithile ezingasebenziyo zonyango lwesinyithi nakwiibhalbhu ukuthintela ukuqhekeka, kodwa ayisebenzi ngamakhemikhali. Yinto ebalulekileyo kubomi bezityalo nezilwanyana, kwaye yinxalenye yeekhompawundi ezininzi eziluncedo. I-nitrogen idibana neentsimbi ezininzi ukwenza ii-nitrides eziqinileyo, ezinokusetyenziswa njengeentsimbi ezinganyangekiyo. Inani elincinci le-nitrogen kwintsimbi liya kuthintela ukukhula kweenkozo kumaqondo obushushu aphezulu kwaye liya kwandisa namandla eentsimbi ezithile. Ingasetyenziselwa ukuvelisa iindawo eziqinileyo kwintsimbi. I-nitrogen ingasetyenziselwa ukwenza i-ammonia, i-nitric acid, i-nitrate, i-cyanide, njl.njl.; ekwenziweni kwezinto eziqhumayo; ukuzalisa ii-thermometers zobushushu obuphezulu, iibhalbhu ze-incandescent; ukwenza izinto ezingasebenziyo ukugcina izinto, ezisetyenziswa kwiibhokisi zokomisa okanye kwiingxowa zeglavu. I-nitrogen engamanzi ngexesha lokukhenkceza ukutya; isetyenziswe njengesipholisi kwilebhu. I-nitrogen kufuneka igcinwe ime nkqo kwindawo enomoya ococekileyo, ekhuselekileyo nengenamozulu, kwaye ubushushu bokugcina akufuneki bube ngaphezulu kwama-52°C. Akufanele kubekho zinto ezinokutsha kwindawo yokugcina kwaye zigcinwe kude neendawo zokungena nokuphuma rhoqo kunye neendawo zokuphuma ezingxamisekileyo, kwaye akukho tyuwa okanye ezinye izinto ezirhabaxa ezikhoyo. Kwiisilinda zegesi ezingasetyenziswanga, isiciko sevalvu kunye nevalvu yokuphuma kufuneka zivalwe kakuhle, kwaye izilinda ezingenanto kufuneka zigcinwe ngokwahlukileyo kwizilinda ezipheleleyo. Kuphephe ukugcina kakhulu kunye nexesha elide lokugcina, kwaye ugcine iirekhodi ezilungileyo zokugcina.

Isicelo:

①Kwizicelo ezahlukeneyo zezixhobo zohlalutyo:

Igesi yokuthwala i-chromatography yegesi, igesi yokuxhasa ii-Electron Capture Detectors, i-Liquid Chromatography Mass Spectrometry, igesi yokucoca i-Inductive Couple Plasma.

②Izinto eziphathekayo:

1. Ukugcwalisa iibhalbhu zokukhanyisa.
2. Kwindawo eneentsholongwane kunye nemixube yezixhobo ezisetyenziselwa ukusetyenziswa kwezinto eziphilayo.
3. Njengenxalenye kwizicelo zokuPakisha i-Atmosphere eLawulwayo kunye nokuPakisha i-Atmosphere eGuquliweyo, 4. Imixube yegesi yokulinganisa iinkqubo zokubeka esweni okusingqongileyo, imixube yegesi yelaser.
5. Ukungasebenzisi iikhemikhali ezininzi, komisa iimveliso okanye izinto ezahlukeneyo.

③I-nitrogen engamanzi:

Njengomkhenkce owomileyo, ukusetyenziswa okuphambili kwe-nitrogen engamanzi kukuyibeka efrijini.

Iphakheji eqhelekileyo:

Inzuzo:

①Iminyaka engaphezu kweshumi ikwimarike;

②Umenzi wesatifikethi se-ISO;

③Ukuhanjiswa okukhawulezayo;
