Kutanga, chimiro che nitrogen
Nitrogen, pasi pemamiriro enguva dzose, igasi risina ruvara, risingarakidze, risinganhuhwi uye kazhinji harina chepfu.Nitrogen inosvika 78.12% yemhepo yese (chikamu chechikamu).Pakupisa kwemazuva ose, igasi.Pakumanikidza kwemuchadenga, inova mvura isina ruvara kana yatonhodzwa kusvika -195.8 ℃.Kana yatonhodzwa kusvika -209.86 ℃, mvura yenitrogen inova yakasimba sechando.Kushandiswa: kemikari synthesis (synthetic nylon, acrylic fiber, synthetic resin, synthetic rubber uye zvimwe zvakakosha zvigadzirwa), matai emotokari (nitrogen inogona kunyatsoderedza ruzha rwematairi, kurebesa hupenyu hwebasa rematairi).Nekuda kwekuti nitrogen inopinza mumakemikari, inowanzoshandiswa segasi rekudzivirira, senge mavise, muchero, chikafu, uye gasi remwenje rinozadza girobhu.
Chechipiri, kushandiswa kwenitrogen
Nitrogen musimbi, indasitiri yemakemikari, mwenje indasitiri, zvemagetsi uye mamwe madhipatimendi, se feedstock gasi, inodzivirira gasi, yekutsiva gasi uye yekuvharisa gasi.Liquid nitrogen zvigadzirwa zvinoshandiswawo zvakanyanya mukudya kwakaomeswa nechando, miriwo uye michero kuchengetedza.Inoshandiswawo zvakanyanya mukurima uye kupfuya mhuka, sekuchengetera zvipembenene zvezviyo, kuchengetwa kwechando kwembeu yezvipfuyo zvepamusoro, etc. Ndiyo inoumba mapuroteni muzvirimwa nemhuka.
Nekufambira mberi kwesainzi uye tekinoroji uye kusimukira kwehupfumi, huwandu hwekushandisa hwenitrogen huri kuwedzera zuva nezuva.
Tora mukana we inertia ye nitrogen
Metal thermal processing: kupenya kudzima, kupenya kupenya, carburizing, carbonitriding, nyoro nitriding uye imwe nitrogen yakavakirwa mumhepo kupisa kurapwa kwenitrogen sosi, welding uye poda metallurgy inopisa nzira yekudzivirira gasi, nezvimwe.
Indasitiri yeMetallurgical: inoenderera mberi ichikanda, inoenderera mberi, simbi inonamira inodzivirira mamiriro ekunze, BOF yepamusoro komputa inofuridza nitrogen simbi, kugadzira simbi BOF chisimbiso, BF chepamusoro chisimbiso, BF ironmaking pulverized marasha jekiseni uye mamwe maitiro.
Kushandisa cryogenic liquid nitrogen
Indasitiri yemagetsi: yakakura-yakabatanidzwa dunhu, ruvara TV yepikicha chubhu, TV uye rekodha zvikamu uye conductor kugadzira maitiro ekudzivirira, nezvimwe.
Kuchengetedzwa kwekudya: chikafu, michero (michero), miriwo uye mamwe mhepo yekuchengetedza uye kuchengetedza, nyama, chizi, masardard, tii uye kofi, senge nyowani yekurongedza, jamu, senge nitrogen oxygenation kuchengetedza, akasiyana mabhodhoro ekuchenesa waini uye kuvhara, etc.
Indasitiri yemishonga: Chinese mushonga (ginseng) nitrogen yekuzadza chengetedzo nekuchengetedza, mushonga wekumadokero jekiseni nitrogen kuzadza, tangi rekuchengetedza uye mudziyo nitrogen inozadza okisijeni, mushonga pneumatic kutapurirana kwemhepo sosi, nezvimwe.
Indasitiri yemakemikari: kutsiva, kuchenesa, kuisa chisimbiso, kuona kuvuza uye kuchengetedzwa kwegasi, kuoma kudzima, kugadzirwa patsva, petroleum fractionation, makemikari fiber kugadzirwa, nezvimwe.
Fertilizer industry: mbishi zvinhu zvenitrogen fetiraiza.Catalyst kudzivirira kopi, kugeza gasi, nezvimwe.
Indasitiri yePurasitiki: pneumatic kutapurirana kwepurasitiki zvimedu, kugadzirwa kwepurasitiki uye kuchengetedza oxidation kudzivirira.
Rubber indasitiri: kurongedza uye kuchengetedza, kugadzira matai, nezvimwe.
Indasitiri yegirazi: Dziviriro gasi rekuyangarara girazi kugadzira maitiro.
Indasitiri yePetroleum: nitrogen kuzadza uye kucheneswa kwekuchengetedza, midziyo, catalytic shongwe uye mapaipi, kudzvinyirirwa kudonha kwekuona kwemanejimendi masisitimu, nezvimwe.
Kuvandudzwa kwemafuta ekuOffshore: gasi rinofukidza mapuratifomu emafuta ekumahombekombe, jekiseni renitrogen rekudzoreredza oiri, tangi uye midziyo inopinza, nezvimwe.
Lump kuchengetedza: kudzivirira cellar, dura uye imwe imba yekuchengetera inopisa guruva kupisa uye kuputika, nezvimwe.
Kutumira: mafuta tanker yekuchenesa gasi, nezvimwe.
Aerospace tekinoroji: roketi mafuta anosimudzira, kuvhura padhi yekutsiva gasi uye kuchengetedza gasi rekudzivirira, astronaut control gasi, nzvimbo yekufananidza nzvimbo, ndege yemafuta pombi yekuchenesa gasi, nezvimwe.
Zvimwe: pendi uye kupfekedza nitrogen oxygenation kudzivirira polymerization yekuomeswa kwemafuta, mafuta uye gasi rekuchengetedza gasi matangi uye midziyo nitrogen oxygenation, nezvimwe.
Kushandisa cryogenic liquid nitrogen
Hypothermia mushonga: kuvhiya hypothermia, cryotherapy, firiji yeropa, kutonhora kwezvinodhaka uye cryopatter, nezvimwe.
Biomedicine: cryopreservation uye kutakura kwezvirimwa zvakakosha, masero ezvirimwa, genetic germplasm, nezvimwe.
