Cov roj av muaj peev xwm muab faib ua cov roj ntshiab thiab muaj kev sib xyaw ua ke ntawm cov pa roj ntshiab thiab kev lag luam lossis cov roj ntau ntawm ib qho roj ntau yam.Hauv National Standard 'Bottle Compressed Gas Classification' (GB16163-1996), nws raug cais raws li lub cev lub cev thiab qhov kub thiab txias hauv lub tog raj kheej roj raws li cov roj ntshiab huv, thiab cov pab pawg hauv cov khoom siv tshuaj lom neeg, combustion, toxicity, thiab corrosive. .
Thawj qeb yog cov roj av tas mus li, thiab nws qhov ntsuas kub tseem ceeb yog <-10 ° C, thaum lub filling, khaws cia thiab kev thauj mus los hauv kev tso cai ua haujlwm kub, muab faib ua pawg A, B: Pab pawg A tsis muaj tshuaj lom thiab tsis muaj tshuaj lom. Cov pa roj carbon monoxide (xws li cov pa oxygen, nitrogen, argon, thiab lwm yam), thiab B pawg yog cov nplaim hluav taws kub thiab tsis muaj tshuaj lom thiab nplaim taws (xws li hydrogen, thiab lwm yam).
Cov chav kawm thib ob yog cov roj liquefied uas nws qhov kub thiab txias yog ≥ -10 ° C, suav nrog cov roj liquefied siab thiab cov roj liquefied tsis tshua muaj siab.Ntawm lawv, qhov kub-siab liquefied roj tseem ceeb yog ≥ -10 ° C, thiab yog ≤70 ° C, uas yog kua thaum lub sij hawm txhaws, tab sis thaum lub sij hawm cia thiab siv thaum lub sij hawm tso cai khiav hauj lwm kub, raws li qhov kub thiab txias yog nce mus rau lub Qhov ntsuas kub tseem ceeb, uas yog, evaporative Lub gaseous, muab faib ua peb pawg ntawm A, B, thiab C: Pawg A yog tsis muaj tshuaj lom thiab tsis muaj tshuaj lom (xws li carbon dioxide), thiab B pawg yog flammable thiab non-toxic thiab Nws tus kheej muaj cov pa phem, thiab C yog yooj yim rau decompose los yog polymerized.Tsawg-pressure liquefied roj qhov tseem ceeb kub> 70 ° C, thaum lub sij hawm them nqi thiab nyob rau hauv lub tso cai ua hauj lwm kub
Thaum lub sijhawm ua haujlwm thiab siv, nws kuj tau muab faib ua peb pawg A, B, C: Pawg A yog tsis muaj tshuaj lom thiab tsis muaj tshuaj lom thiab acidic corrosive gas (xws li chlorine);Pab pawg B yog cov nplaim hluav taws kub thiab tsis muaj tshuaj lom thiab nplaim taws thiab alkaline Corrosion gases (xws li ammonia);C pab pawg yog cov pa roj los yog polymerizable combustible gas.
Cov chav kawm thib peb yog cov roj yaj hauv acetylene, yaj hauv lub tog raj kheej roj hauv qhov siab, thiab tsuas yog Pab Pawg A: Ib pawg ntawm cov roj hluav taws xob los yog cov roj polymeric combustible (xws li acetylene).Qhov no taw tes
Chav kawm yog lub hauv paus rau kev npaj roj sib xyaw.
