Nayitrogeni (N2)

Zosintha zaukadaulo

Nayitrojeni (N2) ndiye gawo lalikulu la mlengalenga wa dziko lapansi, omwe amawerengera 78.08% ya chiwopsezo chonse. Ndi gasi wopanda mtundu, wopanda fungo, wosakoma, wopanda poizoni komanso pafupifupi mpweya wokwanira. Nayitrojeni siwopsereza ndipo imatengedwa ngati mpweya woziziritsa (ndiko kuti, kupuma kwa nayitrogeni woyera kumalepheretsa thupi la munthu mpweya). Nayitrojeni sagwira ntchito ndi mankhwala. Ikhoza kuchitapo kanthu ndi haidrojeni kuti ipange ammonia pansi pa kutentha kwakukulu, kupanikizika kwakukulu ndi zinthu zochititsa chidwi; imatha kuphatikiza ndi okosijeni kupanga nitric oxide pansi pamikhalidwe yotulutsa. Nayitrojeni nthawi zambiri imatchedwa mpweya wa inert. Amagwiritsidwa ntchito m'malo ena opangira zitsulo pochiza zitsulo ndi mababu kuti ateteze kutsetsereka, koma sikuti amangogwiritsa ntchito mankhwala. Ndi chinthu chofunika kwambiri pa moyo wa zomera ndi zinyama, ndipo ndi gawo la zinthu zambiri zothandiza. Nayitrojeni amaphatikiza ndi zitsulo zambiri kuti apange nitrides olimba, omwe amatha kugwiritsidwa ntchito ngati zitsulo zosamva kuvala. Kuchuluka kwa nayitrogeni muzitsulo kudzalepheretsa kukula kwa mbewu pa kutentha kwakukulu komanso kudzawonjezera mphamvu zazitsulo zina. Angagwiritsidwenso ntchito popanga malo olimba pazitsulo. Nayitrogeni angagwiritsidwe ntchito kupanga ammonia, nitric acid, nitrate, cyanide, etc.; popanga zophulika; kudzaza ma thermometers otentha kwambiri, mababu a incandescent; kupanga zinthu zopanda pake kuti zisunge zinthu, zomwe zimagwiritsidwa ntchito m'mabokosi owumitsa kapena matumba a magolovesi. Nayitrogeni wamadzimadzi pa nthawi ya kuzizira kwa chakudya; amagwiritsidwa ntchito ngati ozizira mu labotale. Nayitrojeni iyenera kusungidwa molunjika pamalo olowera mpweya wabwino, wotetezeka komanso wopanda nyengo, ndipo kutentha kusungidwe sikuyenera kupitirira 52°C. Pasakhale zinthu zoyaka moto m'malo osungiramo komanso kukhala kutali ndi malo olowera ndi kutuluka nthawi zambiri komanso potulukira mwadzidzidzi, ndipo pasakhale mchere kapena zowononga zina. Kwa ma silinda a gasi osagwiritsidwa ntchito, kapu ya valve ndi valve yotulutsa iyenera kusindikizidwa bwino, ndipo ma cylinders opanda kanthu ayenera kusungidwa mosiyana ndi ma cylinders onse. Pewani kusungirako kwambiri komanso nthawi yayitali yosungira, ndipo sungani zolemba zabwino zosungirako.

Ntchito:

①Muzida zowunikira zosiyanasiyana:

Gasi wonyamulira wa chromatography ya gasi, gasi wothandizira wa Electron Capture Detectors, Liquid Chromatography Mass Spectrometry, purge gas for Inductive Couple Plasma.

②Zinthu:

1. Kudzaza mababu.
2. Mu antibacterial mlengalenga ndi zida zosakanikirana zachilengedwe.
3. Monga gawo la Controlled Atmosphere Packaging and Modified Atmosphere Packaging applications, 4. Kusakaniza kwa gasi wamagetsi kwa machitidwe owunikira zachilengedwe, kusakaniza kwa gasi la laser.
5. Kuti alowetse zambiri zamakemidwe amawumitsa zinthu zosiyanasiyana kapena zida.

③Nayitrogeni wamadzi:

Mofanana ndi ayezi wouma, ntchito yaikulu ya nayitrogeni yamadzimadzi imakhala ngati firiji.

Phukusi labwinobwino:

Ubwino:

①Kupitilira zaka khumi pamsika;

② ISO wopanga satifiketi;

③Kutumiza mwachangu;

④Stable zopangira gwero;

⑤Dongosolo lowunikira pa intaneti pakuwongolera kwamtundu uliwonse;

⑥Kufunika kwakukulu komanso kusamala pogwira silinda musanadzaze;
