Choyamba, chikhalidwe cha nayitrogeni

Nayitrojeni, mumkhalidwe wabwinobwino, ndi mpweya wopanda mtundu, wosakoma, wopanda fungo ndipo nthawi zambiri umakhala wopanda poizoni.Nayitrojeni amawerengera 78.12% ya mlengalenga wonse (gawo lagawo).Pa kutentha kwabwino, ndi mpweya.Pakuthamanga kwa mumlengalenga, kumakhala madzi opanda mtundu akazizira mpaka -195.8 ℃.Ikazizira mpaka -209.86 ℃, nayitrogeni wamadzimadzi amakhala ngati chipale chofewa.Kagwiritsidwe: kaphatikizidwe ka mankhwala (nayiloni yopangira, acrylic fiber, resin synthetic, rabara yopangira ndi zinthu zina zofunika), matayala agalimoto (nayitrogeni imatha kuchepetsa phokoso la matayala, kutalikitsa moyo wantchito wa matayala).Popeza kuti nayitrogeni ndi amene amalowa mu mankhwala, nthawi zambiri amagwiritsidwa ntchito ngati mpweya woteteza, monga vwende, zipatso, chakudya, ndi mpweya wodzaza mababu.

Chachiwiri, kugwiritsa ntchito nayitrogeni

Nayitrogeni mu zitsulo, makampani opanga mankhwala, mafakitale kuwala, zamagetsi ndi madipatimenti ena, monga feedstock mpweya, zoteteza mpweya, m'malo gasi ndi kusindikiza gasi.Zinthu za nayitrogeni zamadzimadzi zimagwiritsidwanso ntchito kwambiri muzakudya zozizira, masamba ndi kusunga zipatso.Amagwiritsidwanso ntchito kwambiri mu ulimi ndi kuweta nyama, monga insecticidal tirigu yosungirako, mazira yosungirako umuna wapamwamba ziweto, etc. Ndi constituent wa mapuloteni mu zomera ndi nyama.

Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso chitukuko chachuma, kuchuluka kwa nayitrogeni kukukulirakulira tsiku ndi tsiku.

Gwiritsani ntchito mwayi wa nayitrogeni

Chitsulo matenthedwe processing: quenching yowala, annealing kuwala, carburizing, carbonitriding, nitriding zofewa ndi nayitrogeni zina zochokera m'mlengalenga kutentha mankhwala a nayitrogeni gwero, kuwotcherera ndi ufa zitsulo zoyaka moto ndondomeko chitetezo mpweya, etc.

zitsulo makampani: mosalekeza kuponyera, mosalekeza anagubuduza, zitsulo annealing zoteteza mpweya, BOF pamwamba pawiri kuwomba nayitrogeni steelmaking, steelmaking BOF chisindikizo, BF pamwamba chisindikizo, BF ironmaking pulverized malasha jekeseni ndi njira zina.

Kugwiritsa ntchito cryogenic liquid nitrogen

Makampani amagetsi: gawo lalikulu lophatikizika, chubu lachithunzi cha TV, TV ndi zojambulira zida ndi chitetezo cha okonda kupanga, ndi zina zambiri.

Kusungirako chakudya: chakudya, zipatso (zipatso), masamba ndi zina zosungirako mpweya ndi kusunga, nyama, tchizi, mpiru, tiyi ndi khofi, monga ma CD mwatsopano, kupanikizana, monga nayitrogeni oxygenation kusunga, mabotolo osiyanasiyana vinyo kuyeretsedwa ndi chophimba, ndi zina.

Makampani opanga mankhwala: Mankhwala aku China (ginseng) kusungirako ndikusunga nayitrogeni, mankhwala akumadzulo a jakisoni wa nayitrogeni, thanki yosungiramo ndi chidebe chodzaza mpweya wa nayitrogeni, kutumiza kwa pneumatic kwa mpweya, etc.

Makampani a Chemical: m'malo, kuyeretsa, kusindikiza, kuzindikira kutayikira ndi kuteteza gasi, kuzimitsa kowuma, kusinthika kothandizira, kugawa mafuta, kupanga ma fiber, etc.

Makampani a feteleza: zopangira za feteleza wa nayitrogeni.Kope lachitetezo chothandizira, gasi wochapira, ndi zina.

Makampani apulasitiki: kufala kwa pneumatic kwa tinthu tating'onoting'ono tapulasitiki, kupanga pulasitiki ndi kupewa kuteteza okosijeni.

Makampani a mphira: kuyika ndi kusungirako mphira, kupanga matayala, etc.

Makampani agalasi: Gasi woteteza popanga magalasi oyandama.

Makampani a petroleum: kudzaza nayitrogeni ndikuyeretsa posungira, zotengera, nsanja zothandizira ndi mapaipi, kuzindikira kutayikira kwamayendedwe kasamalidwe, ndi zina zambiri.

Kukula kwamafuta akunyanja: kuphimba gasi pamapulatifomu amafuta akunyanja, jakisoni wa nayitrogeni pakubwezeretsa mafuta, tanki ndi kulowetsa ziwiya, ndi zina.

Kusungirako mphumphu: kuteteza cellar, barani ndi malo ena osungira fumbi kuyatsa ndi kuphulika, etc.

Kutumiza: gasi woyeretsa matanki amafuta, etc.

Ukadaulo wamumlengalenga: chowonjezera chamafuta a rocket, kuyambitsa gasi wolowa m'malo ndi chitetezo chachitetezo, gasi wowongolera wapamlengalenga, chipinda chofananira mlengalenga, mpweya woyeretsa mapaipi a ndege, ndi zina zambiri.

Other: utoto ndi ❖ kuyanika nayitrogeni oxygenation kuteteza polymerization wa kuyanika mafuta, mafuta ndi gasi yosungirako akasinja ndi muli nayitrogeni oxygenation, etc.

Kugwiritsa ntchito cryogenic liquid nitrogen

Hypothermia mankhwala: opaleshoni hypothermia, cryotherapy, magazi firiji, mankhwala kuzizira ndi cryopatter, etc.

Biomedicine: cryopreservation ndi kayendedwe ka zomera zamtengo wapatali, maselo a zomera, majeremusi amtundu, etc.
