Txawm hais tias muaj cov pa roj carbon monoxide feem ntau muaj nyob rau hauv daim ntawv tsis muaj xim thiab tsis muaj ntxhiab, lawv ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv ntau qhov kev lag luam. Lawv cov kev siv ntau yam thiab qhov cuam tshuam loj heev cuam tshuam rau tag nrho cov saw hlau los ntawm kev tsim khoom yooj yim mus rau kev txiav- thev naus laus zis, ua rau lawv muaj kev txhawb nqa tseem ceeb rau kev lag luam niaj hnub no.
Nyob rau hauv metallurgical thiab hlau ua teb, industrial gases yog cov xov xwm tseem ceeb rau cov txheej txheem tseem ceeb. Oxygen, siv hauv steelmaking, tuaj yeem ua kom kub kub thiab cov tshuaj tiv thaiv, txo cov voj voog smelting, thiab txo cov roj noj; nitrogen ua raws li kev tiv thaiv roj hauv kev kho cua sov hlau, tiv thaiv cov ntaub ntawv los ntawm oxidizing thiab decarburizing ntawm qhov kub thiab txias, kom ntseeg tau cov khoom siv kho tshuab; argon tsim cov cua inert thaum lub sij hawm welding ntawm stainless hlau thiab tsis yog -ferrous hlau, tiv thaiv porosity thiab tawg nyob rau hauv welds, thiab txhim kho kev twb kev txuas lub zog thiab sealing.
Hauv kev lag luam tshuaj thiab hluav taws xob, cov khoom siv roj tau koom nrog ntau yam kev sib txuas thiab kev hloov pauv. Hydrogen, uas yog ib qho tseem ceeb raw cov ntaub ntawv, yog dav siv nyob rau hauv synthesis ntawm ammonia, methanol, thiab hydrorefining, txhawb kev ntxuav chiv thiab roj refining. Cov pa roj carbon dioxide tuaj yeem siv rau hauv urea synthesis, oilfield txhim kho cov roj rov qab, thiab khoom noj khoom haus -qib foaming, ntsuas tus nqi lag luam- ntxiv nrog cov peev txheej rov ua dua. Nitrogen yog siv los ua kev hloov pauv thiab purging roj hauv cov nroj tsuag tshuaj, ua kom lub cev muaj kev nyab xeeb thiab cov tshuaj tiv thaiv purity.
Hauv electronics thiab optoelectronics industries, siab -purity tshwj xeeb gases txiav txim siab precision manufacturing. High-purity nitrogen, argon, thiab helium yog siv los tswj qhov chaw huv thiab muab cua txias hauv semiconductor wafer ntau lawm; fluorine- thiab chlorine- muaj cov pa roj tshwj xeeb yog siv rau plasma etching thiab nyias- zaj duab xis tso tawm, ua kom muaj kev tsim cov qauv ntawm nanoscale Circuit Court; laser sib tov muab qhov chaw ruaj khov rau kev sib txuas lus fiber ntau optic thiab precision machining.
Hauv kev kho mob thiab kev noj qab haus huv, kev kho mob cov pa oxygen ncaj qha txhawb nqa txoj kev ua pa thiab kev kho mob thaum muaj xwm txheej ceev, nitrous oxide ua lub luag haujlwm hauv kev kho mob tsis mob, thiab kev kho mob carbon dioxide yog siv los tsim pneumoperitoneum hauv kev phais me me xws li laparoscopy. Kev lag luam khoom noj khoom haus siv cov pa roj carbon dioxide thiab nitrogen rau kev hloov pauv huab cua ntim thiab khaws cia kom khov, txuas lub neej txee thiab tswj kom zoo.
Tsis tas li ntawd, kev lag luam gases muaj kev siv dav hauv kev tshawb fawb thiab kev sim, kev saib xyuas ib puag ncig, thiab aerospace propulsion. Nws muaj peev xwm nkag mus rau ntau qhov xwm txheej thiab thoob plaws kev lag luam qhia txog tus nqi tseem ceeb ntawm kev lag luam gases raws li lub zog tsis pom hauv kev lag luam niaj hnub.
