Cov gases siv rau blasting thiab so lub unsolidified zinc kua nyob rau hauv lub puab phab ntsa ntawm galvanized steel kav feem ntau muaj xws li superheated chav, compressed cua, pressurized kub, thiab saturated chav, ntawm cov uas superheated chav yog siv ntau dua. Qhov no yog vim tias cov chav superheated tuaj yeem ua kom sov siab tshaj qhov zinc solidification point nyob rau hauv cov txheej txheem txheej txheem siab thiab muaj cov dej noo tsawg heev. Thaum siv los tawg thiab so cov kua zinc ntawm cov phab ntsa sab hauv ntawm cov kav dej galvanized, nws tsis txias cov kua zinc; hloov, nws nce nws qhov kub thiab txias me ntsis. Qhov no yog qhov zoo rau blasting thiab so cov kua zinc ntawm sab hauv phab ntsa kom ua tiav qhov chaw du. Tsis tas li ntawd, cov cuab yeej siv rau kev tsim cov chav superheated yog qhov yooj yim thiab tuaj yeem siv tau yooj yim hauv ntau lub hoobkas. Hauv qhov sib piv, saturated chav muaj cov dej noo ntau dua thiab muaj qhov kub thiab txias, uas tuaj yeem nqus cua sov los ntawm cov kua zinc thiab ua kom nws lub zog. Cov cua compressed, txawm tias tsis muaj dej noo, tuaj yeem ua kom lub zog ntawm cov kua zinc, ua rau cov cua compressed los ntawm lub puab tsaig ntawm cov kav dej galvanized thiab cuam tshuam cov txheej txheem blasting thiab so. Kev siv cov cua kub siab rau sab hauv blasting thiab so ntawm zinc tsis tshua muaj tshwm sim vim muaj teeb meem hauv kev ua tiav qhov yuav tsum tau muaj qhov kub thiab txias, siab, thiab ntws tus nqi, nrog rau cov khoom siv ntau dua thiab kev siv zog.
Yog hais tias compressed cua yog thawj zaug siv rau sab nraud blasting thiab so, nws yog ib qho tsim nyog yuav tau txais superheated chav (los yog cua kub pressurized) ntawm qhov kub thiab txias siab rau sab hauv blasting thiab so ntawm zinc.
