Ua ntej, qhov xwm ntawm nitrogen

Nitrogen, nyob rau hauv ib txwm muaj mob, yog xim tsis muaj xim, tsis qab, tsis muaj ntxhiab tsw thiab feem ntau tsis muaj tshuaj lom.Nitrogen suav txog 78.12% ntawm tag nrho cov huab cua (qhov feem pua).Ntawm qhov kub thiab txias, nws yog ib qho roj.Ntawm tus qauv atmospheric siab, nws dhau los ua kua tsis muaj xim thaum nws txias rau -195.8 ℃.Thaum nws txias rau -209.86 ℃, kua nitrogen ua cov khoom zoo li daus.Kev siv: cov khoom siv hluavtaws (synthetic nylon, acrylic fiber, hluavtaws cob, hluavtaws roj hmab thiab lwm yam ntaub ntawv tseem ceeb), tsheb log tsheb (nitrogen tuaj yeem txo lub suab nrov ntawm lub log tsheb, ua kom lub neej ntev ntawm cov log tsheb).Vim tias nitrogen tsis muaj tshuaj lom neeg, nws feem ntau yog siv los ua cov roj tiv thaiv, xws li cov txiv hmab txiv ntoo, txiv hmab txiv ntoo, zaub mov, thiab lub teeb ntim roj.

Ob, siv cov nitrogen

Nitrogen hauv metallurgy, tshuaj lom neeg kev lag luam, lub teeb kev lag luam, electronics thiab lwm yam departments, raws li feedstock gas, tiv thaiv roj, hloov roj thiab sealing gas.Cov khoom ua kua nitrogen kuj tau siv dav hauv cov khoom noj khov, zaub thiab txiv hmab txiv ntoo khaws cia.Nws kuj yog siv dav hauv kev ua liaj ua teb thiab tsiaj txhu, xws li tshuaj tua kab kab cia, khov cia ntawm cov phev ntawm cov tsiaj nyeg, thiab lwm yam. Yog cov ntsiab lus ntawm cov protein nyob hauv cov nroj tsuag thiab tsiaj txhu.

Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev loj hlob ntawm kev lag luam, daim ntawv thov ntawm nitrogen tau nthuav dav txhua hnub.

Ua kom zoo dua ntawm inertia ntawm nitrogen

Hlau thermal ua: ci quenching, ci annealing, carburizing, carbonitriding, mos nitriding thiab lwm yam nitrogen raws cua kub kev kho mob ntawm nitrogen qhov chaw, vuam thiab hmoov metallurgy hlawv txheej txheem tiv thaiv roj, thiab lwm yam.

Kev lag luam metallurgical: nruam casting, nruam dov, steel annealing tiv thaiv cua, BOF sab saum toj compound tshuab nitrogen steelmaking, steelmaking BOF foob, BF sab saum toj foob, BF ironmaking pulverized thee txhaj tshuaj thiab lwm yam txheej txheem.

Siv cryogenic kua nitrogen

Kev lag luam hauv hluav taws xob: kev sib xyaw ua ke loj loj, xim TV duab raj, TV thiab recorder Cheebtsam thiab tus neeg xyuas pib tsim cov txheej txheem tiv thaiv, thiab lwm yam.

Kev khaws cia zaub mov: zaub mov, txiv hmab txiv ntoo (txiv hmab txiv ntoo), zaub thiab lwm yam cua txias cia thiab khaws cia, nqaij, cheese, mustard, tshuaj yej thiab kas fes, xws li cov ntim tshiab, jam, xws li nitrogen oxygenation preservation, ntau lub raj mis ntawm cawv purification thiab npog, lwm.

Kev lag luam kws tshuaj: Suav tshuaj (ginseng) nitrogen filling cia thiab khaws cia, western tshuaj txhaj nitrogen filling, cia tank thiab ntim nitrogen filling oxygen, tshuaj pneumatic kis tau tus mob ntawm huab cua qhov chaw, thiab lwm yam.

Kev lag luam tshuaj: hloov, tu, sealing, xau thiab tiv thaiv cov roj, qhuav quenching, catalyst regeneration, roj av fractionation, tshuaj fiber ntau, thiab lwm yam.

Fertilizer kev lag luam: raw khoom ntawm nitrogen chiv.Catalyst tiv thaiv daim ntawv, ntxuav roj, thiab lwm yam.

Plastics kev lag luam: pneumatic kis tau tus mob ntawm cov khoom yas, yas ntau lawm thiab cia oxidation tiv thaiv.

Roj hmab kev lag luam: roj hmab ntim thiab cia, log tsheb tsim, thiab lwm yam.

Kev lag luam iav: Kev tiv thaiv roj rau ntab iav txheej txheem ntau lawm.

Petroleum kev lag luam: nitrogen filling thiab purification ntawm cia, ntim, catalytic yees thiab pipelines, siab leak nrhiav kom tau cov kev tswj, thiab lwm yam.

Offshore roj kev loj hlob: roj npog ntawm offshore roj platforms, nitrogen txhaj rau roj rov qab, tank thiab thawv inerting, thiab lwm yam.

Lub thawv cia: txhawm rau tiv thaiv cellar, lub tsev txhab nyiaj thiab lwm lub tsev khaws khoom pov tseg cov plua plav hluav taws xob thiab tawg, thiab lwm yam.

Shipping: roj tanker ntxuav roj, thiab lwm yam.

Aerospace technology: foob pob hluav taws roj booster, tso pa taws hloov roj thiab kev tiv thaiv kev nyab xeeb roj, astronaut tswj roj, chaw simulation chav, aircraft roj pipeline tu roj, thiab lwm yam.

Lwm yam: xim thiab txheej txheej nitrogen oxygenation los tiv thaiv cov polymerization ntawm cov roj kom qhuav, cov roj thiab cov nkev cia tank thiab ntim cov nitrogen oxygenation, thiab lwm yam.

Siv cryogenic kua nitrogen

Hypothermia tshuaj: phais hypothermia, cryotherapy, ntshav tub yees, tshuaj khov thiab cryopatter, thiab lwm yam.

Biomedicine: cryopreservation thiab kev thauj mus los ntawm cov nroj tsuag muaj txiaj ntsig, cov hlwb cog, cov kab mob caj ces, thiab lwm yam.
