Cov piv txwv ntawm kev lag luam gases yog dab tsi?
Industrial gases ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam thiab kev lag luam, muab cov ntsiab lus tseem ceeb thiab txhim kho cov txheej txheem tsim khoom. Cov pa roj carbon monoxide no, uas feem ntau yog tsim los ntawm ntau qhov ntau thiab siab purity, muaj ntau yam kev siv hauv thaj chaw xws li kev tsim tshuaj lom neeg, hlau refining, khoom noj thiab dej haus, kev kho mob, thiab lwm yam. Hauv tsab xov xwm no, peb yuav tshawb txog qee qhov piv txwv ntawm kev lag luam gases thiab lawv siv.
1. Cov pa oxygen (O2):
Oxygen yog ib qho ntawm cov khoom siv dav siv ntau tshaj plaws. Nws yog ib qho tseem ceeb rau ntau yam txheej txheem combustion, xws li cov tshwm sim nyob rau hauv furnaces, kilns, thiab boilers. Oxygen kuj tseem ceeb heev hauv cov hlau txiav thiab vuam ua haujlwm vim nws ua kom yooj yim dua thiab siv tau zoo dua. Tsis tas li ntawd, oxygen pom cov ntawv thov hauv cov chaw kho mob los pab cov neeg mob ua pa thiab hauv cov txheej txheem kho dej.
2. Nitrogen (N2):
Nitrogen yog lwm cov roj siv dav siv hauv kev lag luam. Nws cov khoom inert ua rau nws tsim nyog rau ntau yam kev siv uas yuav tsum muaj qhov chaw tsis muaj zog. Nitrogen feem ntau yog siv rau daim pam cia tso tsheb hlau luam thiab cov kav dej los tiv thaiv oxidation lossis degradation ntawm cov ntaub ntawv rhiab heev. Nws kuj tseem siv rau hauv kev lag luam zaub mov thiab dej haus kom tshem tawm cov pa oxygen thiab txuas ntxiv cov khoom txee lub neej. Tsis tas li ntawd, nitrogen muaj cov ntawv thov hauv kev lag luam hluav taws xob thaum lub sij hawm tsim khoom ntawm semiconductors.
3. Cov pa roj carbon dioxide (CO2):
Cov pa roj carbon dioxide yog ntau yam kev lag luam roj nrog ntau hom kev siv. Hauv kev lag luam khoom noj khoom haus thiab dej haus, CO2 yog siv rau carbonating dej haus, khov cov khoom noj, thiab raws li ib tug preservative mus rau lub neej txee. Nws kuj tseem pom cov ntawv thov hauv cov hluav taws tua hluav taws, qhov chaw uas nws txav cov pa oxygen kom tshem tawm cov hluav taws kub. Tsis tas li ntawd, carbon dioxide yog siv nyob rau hauv kev lag luam xws li roj thiab roj, tshuaj, thiab tshuaj raws li ib tug hnyav los yog raw khoom nyob rau hauv ntau yam txheej txheem.
4. Hydrogen (H2):
Hydrogen muaj ntau daim ntawv thov kev lag luam, feem ntau hauv kev lag luam tshuaj. Nws yog ib qho tseem ceeb hauv kev tsim cov ammonia, methanol, thiab lwm yam tshuaj. Hydrogen kuj tseem siv rau hauv cov roj av refineries kom tshem tawm impurities los ntawm cov roj. Tsis tas li ntawd, cov roj hlwb uas tsim hluav taws xob los ntawm kev sib xyaw hydrogen thiab oxygen tau txais txiaj ntsig zoo li lub zog huv rau ntau yam kev siv, suav nrog kev thauj mus los.
5. Argon (Argon):
Argon yog ib qho roj inert feem ntau siv hauv kev lag luam hlau. Nws tsis tshua muaj reactivity thiab siab thermal conductivity ua rau nws zoo tagnrho rau shielding vuam txheej txheem, txo qhov kev pheej hmoo ntawm weld contamination thiab txhim kho qhov zoo ntawm welds. Argon kuj tseem siv rau hauv kev tsim cov iav tshwj xeeb thiab ua ib qho chaw tiv thaiv hauv kev kho cua sov ntawm cov hlau.
6. Helium (Nws):
Helium, paub txog nws qhov ntom ntom thiab siab thermal conductivity, pom cov ntawv thov hauv ntau yam kev lag luam. Nws yog dav siv nyob rau hauv daim ntawv thov cryogenic, xws li cua txias superconducting hlau nplaum hauv magnetic resonance imaging (MRI) cov cav tov thiab lwm yam khoom siv scientific. Helium's inert zog kuj ua rau nws tsim nyog rau kev kuaj pom hauv kev lag luam thiab ua cov pa roj hauv cov roj chromatography.
7. Acetylene (C2H2):
Acetylene yog ib qho hluav taws kub heev uas muaj roj siv rau ntau yam kev siv, feem ntau hauv kev ua hlau. Nws cov cua kub tso tawm thaum lub sij hawm combustion ua rau nws zoo tagnrho rau oxy-acetylene vuam, txiav, thiab brazing kev khiav hauj lwm. Acetylene kuj yog siv rau hauv cov tshuaj synthesis ntawm ntau yam organic tebchaw thiab ua ib tug roj rau portable teeb pom kev zoo thiab cua sov.
8. Chlorine (Cl2):
Cov tshuaj chlorine yog cov roj corrosive thiab tshuaj lom neeg feem ntau siv hauv kev lag luam tshuaj lom neeg los tsim ntau cov tebchaw, suav nrog cov tshuaj chlorine-raws li cov kuab tshuaj, plastics, thiab tshuaj ntxuav. Nws kuj yog ib qho tshuaj tua kab mob tseem ceeb rau kev kho dej kom tshem tawm cov kab mob tsis zoo. Txawm li cas los xij, vim nws cov tshuaj tiv thaiv thiab toxicity, chlorine yuav tsum tau ceev faj tuav thiab ntsuas ntsuas.
9. Ammonia (NH3):
Ammonia plays lub luag haujlwm tseem ceeb hauv kev lag luam chiv ua ib qho tseem ceeb hauv kev tsim cov chiv nitrogen. Nws kuj tseem siv los ua cov tub yees hauv cov tshuab tub yees vim nws lub peev xwm nqus cua sov siab. Ammonia pom daim ntawv thov nyob rau hauv ntau yam tshuaj synthesis txheej txheem thiab plays lub luag hauj lwm nyob rau hauv kev tsim tshuaj, dyes, thiab plastics.
10. Sulfur Dioxide (SO2):
Sulfur dioxide feem ntau yog siv rau hauv kev tsim cov sulfuric acid, ib qho tseem ceeb tshuaj nyob rau hauv ntau yam lag luam, xws li chiv, detergents, thiab roj teeb. SO2 kuj pom daim ntawv thov raws li kev khaws cia hauv winemaking los tiv thaiv kev lwj thiab oxidation. Ntxiv mus, nws yog siv los ua tus neeg sawv cev txo qis hauv qee cov txheej txheem kev lag luam thiab tshuaj tua kab mob hauv dej kom huv.
Xaus:
Kev lag luam gases yog ntau haiv neeg thiab cov khoom tseem ceeb rau ntau cov haujlwm thiab kev siv. Los ntawm cov pa oxygen thiab nitrogen mus rau carbon dioxide thiab hydrogen, txhua lub roj ua haujlwm tshwj xeeb thiab pab txhawb rau kev tsim khoom, tshuaj synthesis, hlau ua haujlwm, kev kho mob, thiab lwm yam. Nkag siab txog cov kev lag luam gases thiab lawv cov ntawv thov yog qhov tseem ceeb rau kev lag luam thiab kev lag luam los txhim kho lawv cov haujlwm thiab ua kom muaj txiaj ntsig zoo.
