Cov kua pa oxygen yog cov kua xiav daj ntseg ntawm qhov kub thiab txias, nrog rau qhov kub thiab txias heev. Qhov kub ntawm cov kua oxygen yog -183 ℃, uas ua rau nws ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig piv rau gaseous oxygen. Nyob rau hauv cov ntaub ntawv ua kua, qhov ceev ntawm oxygen yog kwv yees li 1.14 g / cm³, ua kua oxygen yooj yim rau khaws thiab thauj dua gaseous oxygen. Cov pa oxygen tsis yog tsuas yog muaj cov pa oxygen siab xwb tab sis kuj muaj cov khoom muaj zog oxidizing, muaj peev xwm ua tau sai sai nrog ntau cov organic tshuaj.

Cov yam ntxwv ntawm qhov kub thiab txias ntawm cov kua oxygen yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev ntsuas thaum lub sijhawm khaws cia thiab kev thauj mus los, xws li siv cov thawv uas tsis muaj qhov kub thiab txias los tiv thaiv cov cua sov. Nws tsis muaj ntxhiab tsw thiab tsis muaj xim, tab sis vim nws qhov kub thiab txias tsis tshua muaj, cov pa oxygen ua kua yuav ua rau frostbite thiab lwm yam kev phom sij rau tib neeg lub cev, yog li yuav tsum tau saib xyuas tshwj xeeb thaum lub sijhawm ua haujlwm.

Kev tsim thiab tsim cov txheej txheem ua kua oxygen

Kev tsim cov kua oxygen feem ntau yog siv cov tshuab sib sib zog nqus cryogenic huab cua sib cais, uas yog ib txoj hauv kev sib cais cov khoom ntawm cov huab cua los ntawm qhov kub thiab txias txias thiab ua kom zoo compression. Lub hauv paus ntsiab lus ntawm kev sib sib zog nqus cryogenic huab cua sib cais yog cais ntau yam ntawm huab cua raws li lawv cov ntsiab lus sib txawv. Ua ntej, huab cua yog compressed, tom qab ntawd los ntawm ntau theem ntawm kev nthuav dav thiab txias, huab cua maj mam nce mus txog qhov kub tsis tshua muaj siab, thiab thaum kawg oxygen tau cais tawm ntawm huab cua thiab liquefied. Kev tsim cov kua oxygen yuav tsum tau ua kom muaj cua txias kom zoo thiab cov cuab yeej ua kom huv huv kom ntseeg tau tias cov purity thiab stability ntawm cov kua oxygen.

Sib sib zog nqus cryogenic huab cua sib cais tshuab tuaj yeem tsis tsuas yog tsim cov pa oxygen xwb tab sis kuj tseem tau txais lwm cov roj cua kub xws li kua nitrogen thiab kua argon. Cov khoom no kuj muaj kev siv dav hauv kev lag luam. Lub siab purity thiab qis-kub yam ntxwv ntawm cov kua oxygen ua rau nws tseem ceeb hauv ntau daim ntawv thov tshwj xeeb.

Lub ntsiab daim ntawv thov teb ntawm kua oxygen

Cov pa oxygen ua kua muaj kev siv dav hauv ntau qhov chaw lag luam. Ua ntej, nyob rau hauv aerospace teb, kua oxygen yog ib qho ntawm feem ntau siv foob pob ua ntxaij oxidants, raws li nws muaj ib tug siab oxygen cov ntsiab lus thiab combustion kev pab muaj peev xwm, uas muaj peev xwm hnov ​​​​mob nrog roj sai heev los tsim ib tug loj npaum li cas ntawm lub zog rau propel foob pob ua ntxaij launches. Kev sib xyaw ua ke ntawm cov pa oxygen thiab kua hydrogen yog hu ua ib qho ntawm cov foob pob hluav taws ntau tshaj plaws, thiab nws lub zog thrust thiab kev ua tau zoo heev ua rau nws nyiam heev hauv aerospace technology.

Thib ob, hauv kev kho mob, kua oxygen yog siv los ua cov pa oxygen tseem ceeb. Cov pa oxygen yog khaws cia ntawm qhov kub thiab txias thiab vaporized rau kev siv cov pa oxygen, pab cov neeg mob ua pa nyuaj kom tau txais cov pa oxygen txaus. Tsis tas li ntawd, kua oxygen ua lub luag haujlwm tseem ceeb hauv metallurgy, chemical engineering, thiab lwm yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv high-temperature combustion thiab chemical synthesis processes, qhov twg nws muaj zog oxidizing muaj peev xwm yog dav siv.

Kev tiv thaiv kev nyab xeeb rau cov kua oxygen

Txawm hais tias cov pa oxygen ua kua muaj kev siv dav, vim nws qhov kev ua haujlwm siab thiab cov yam ntxwv kub qis, muaj qee yam kev nyab xeeb. Ua ntej, kua oxygen yog ib qho muaj zog oxidant, uas tuaj yeem ua kom cov txheej txheem combustion, yog li nws yuav tsum raug zam los ntawm kev sib cuag nrog cov khoom siv hluav taws xob thaum khaws cia thiab siv. Nyob rau tib lub sijhawm, qhov kub tsis tshua muaj siab ntawm cov pa oxygen tuaj yeem ua rau frostbite, yog li cov cuab yeej tiv thaiv tsim nyog xws li cov hnab looj tes tiv thaiv kab mob khaub thuas thiab lub qhov ncauj qhov ntswg yuav tsum tau hnav thaum ua haujlwm ua kua oxygen kom tsis txhob raug mob ntawm daim tawv nqaij thiab qhov muag.

Kev khaws cia ntawm cov pa oxygen yuav tsum tau tsim tshwj xeeb hauv cov thawv uas muaj qhov kub thiab txias, uas feem ntau muaj cov khoom siv rwb thaiv tsev zoo los tiv thaiv cov cua sov sab nraud los ntawm kev nkag mus thiab ua rau qhov kub ntawm cov kua oxygen nce. Tsis tas li ntawd, thaum lub sij hawm vaporization txheej txheem ntawm cov kua oxygen, nws yuav nthuav dav thiab tsim cov pa oxygen ntau, uas tuaj yeem ua rau muaj qhov nce ntawm cov pa oxygen hauv ib puag ncig, ua rau muaj kev pheej hmoo ntawm hluav taws. Yog li ntawd, thaum lub sij hawm cia thiab kev thauj mus los ntawm cov kua oxygen, cov kev cai muaj feem xyuam rau kev nyab xeeb yuav tsum tau ua raws li nruj me ntsis raws li kom muaj kev nyab xeeb nyob rau hauv lub chaw ua hauj lwm thiab qhov cua.

Kev sib piv ntawm cov pa oxygen ua kua nrog rau lwm cov pa roj

Cov pa oxygen, xws li kua nitrogen thiab kua argon, qhia qee qhov zoo sib xws ntawm lub cev, tab sis muaj qhov sib txawv tseem ceeb hauv daim ntawv thov thiab cov khoom. Qhov kub ntawm cov kua nitrogen yog -196 ℃, uas yog qis dua li cov pa oxygen, yog li cov kua nitrogen feem ntau yog siv los ua cov dej txias, thaum cov pa oxygen, vim nws cov khoom muaj zog oxidizing, feem ntau yog siv los ua kev pab cuam los yog oxidant. Tsis tas li ntawd, cov kua argon, uas yog cov roj inert, tsis nquag ua rau muaj kev cuam tshuam nrog lwm yam tshuaj thaum muaj tshuaj lom neeg thiab feem ntau yog siv los tiv thaiv huab cua. Thaum cov pa oxygen ua kua, vim nws cov reactivity siab, feem ntau yog siv nyob rau hauv tshuaj synthesis thiab combustion txheej txheem.

Ntawm cov kev lag luam gases, kua oxygen yog qhov tshwj xeeb vim nws cov khoom muaj zog oxidizing, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau muaj zog combustion thiab khaus oxidation cov tshuaj tiv thaiv. Cov yam ntxwv ntawm cov pa roj sib txawv ua rau lawv ua lub luag haujlwm tseem ceeb hauv lawv cov ntawv thov kev lag luam.

Ib puag ncig tus phooj ywg thiab sustainability ntawm kua oxygen

Txawm hais tias cov pa oxygen ua kua, raws li cov khoom siv roj, muaj qhov ua haujlwm siab heev hauv daim ntawv thov, nws tsis ua rau muaj kuab paug rau ib puag ncig hauv cov ntsiab lus. Oxygen, ua ib feem tseem ceeb ntawm cov huab cua, nws cov khoom kawg hauv cov txheej txheem tshuaj tiv thaiv feem ntau yog cov khoom tsis zoo xws li dej lossis carbon dioxide. Txawm li cas los xij, cov txheej txheem tsim cov kua oxygen xav tau ntau lub zog, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem sib sib zog nqus txias txias, yog li kev txhim kho lub zog ntawm cov kua oxygen ntau lawm yog qhov tseem ceeb heev rau kev tiv thaiv ib puag ncig.

Los ntawm kev siv cov cuab yeej siv tau zoo dua thiab txhim kho cov txheej txheem ntws, nws tuaj yeem txo qis kev siv hluav taws xob thaum txo qhov cuam tshuam ib puag ncig ntawm cov kua oxygen ntau lawm. Nrog rau txoj kev loj hlob ntawm ntsuab zog technologies, zus tau tej cov kua pa oxygen yuav tsum ua ntau environmentally friendly thiab sustainable nyob rau hauv lub neej yav tom ntej, muab ib tug huv qhov chaw ntawm oxygen rau industrial ntau lawm thiab tib neeg lub neej. Xaus

Cov pa oxygen ua kua, ua kua hauv cov pa oxygen, tau siv dav hauv kev lag luam, aerospace, thiab kev kho mob vim nws lub cev tshwj xeeb thiab muaj zog oxidizing xwm. Txawm hais tias kev tsim thiab siv cov kua oxygen xav tau kev ntsuas kev nyab xeeb nruj, nws lub luag haujlwm tseem ceeb hauv ntau qhov chaw yog irreplaceable. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm thev naus laus zis tsis tu ncua, kev tsim khoom thiab kev siv cov pa oxygen yuav tsum ua kom muaj txiaj ntsig zoo thiab ib puag ncig zoo, yog li ua tau raws li cov kev xav tau ntawm tib neeg.
