Qhov sib txawv tseem ceeb ntawm cov pa roj tshwj xeeb thiab cov roj hluav taws xob zoo tib yam yog nyob rau hauv plaub qhov loj: purity, daim ntawv thov, cov khoom, thiab cov kev xav tau siv.
Nyob rau hauv cov nqe lus ntawm purity, zoo tib yam industrial gases muaj qis purity (xws li, industrial nitrogen feem ntau yog 99.5%-99.9%), ua tau raws li cov kev xav tau ntawm kev lag luam; cov roj tshwj xeeb muaj cov purity siab heev (Ntau dua lossis sib npaug li 99.999%), haum rau siab -qhov tseeb thiab qhov xav tau siab.
Hais txog cov ntawv thov, cov pa roj carbon monoxide zoo tib yam yog siv dav hauv - lub hom phiaj xwm txheej, xws li oxygen rau vuam thiab txiav, nitrogen rau kev tiv thaiv yooj yim inert, thiab carbon dioxide rau tua hluav taws lossis kev txuag zaub mov; gases tshwj xeeb yog siv rau hauv cov txheej txheem tshwj xeeb lossis siab -kawg teb, xws li cov roj hluav taws xob tshwj xeeb rau kev tsim cov chips, cov pa roj tshwj xeeb rau kev siv tshuaj loog lossis kev kho mob, thiab cov kev tshawb fawb tshawb fawb tshwj xeeb gases rau kev txiav- ntug kev sim.
Hais txog cov khoom, cov roj av zoo tib yam feem ntau yog tib yam -cov khoom thiab ruaj khov (piv txwv li, nitrogen thiab argon yog inert heev), nrog rau kev phom sij tsawg; Cov pa roj tshwj xeeb qee zaum muaj cov nplaim taws, tawg, muaj kuab lom, lossis cov khoom muaj zog heev, ua rau muaj kev pheej hmoo siab dua rau ib puag ncig thiab tib neeg kev noj qab haus huv. Nyob rau hauv cov nqe lus ntawm kev siv yuav tsum tau, zoo tib yam industrial gases muaj yooj yim daim ntawv thov txheej txheem thiab tsawg yuav tsum tau rau cov khoom thiab ib puag ncig; Cov roj tshwj xeeb xav tau cov cuab yeej tshwj xeeb, kev tswj xyuas meej ntawm qhov ntsuas (kub, siab, ntws tus nqi), thiab cov neeg ua haujlwm yuav tsum tau txais kev cob qhia.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov scenarios, zoo tib yam industrial gases yog tsim rau cov tsoos industrial ntau lawm (xws li steel smelting thiab tsev welding) thiab cov kev xav tau txhua hnub (xws li kev khaws zaub mov thiab kev txiav dav dav); Txawm li cas los xij, rau cov ntawv thov hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, kev kho mob siab - kawg kev kho mob, cov tshuaj precision, thiab txiav- kev tshawb fawb txog kev tshawb fawb, cov hom roj tshwj xeeb yuav tsum raug xaiv, xws li hluav taws xob tshwj xeeb gases rau chip manufacturing, ultra- siab purity helium rau nuclear magnetic resonance imaging khoom rau tumor radon.
