Thaum pib ntawm sab nraud blasting thiab so ntawm zinc, nws yuav tsum tau muab ob npaug rau cov roj ntws los xyuas kom meej tias cov galvanized steel yeeb nkab nkag mus rau hauv cov pa roj. Muaj ob qho laj thawj rau qhov no:
(1) Qhov kawg ntawm cov yeeb nkab steel galvanized uas tawm ntawm cov zinc molten ua ntej txias hauv huab cua rau lub sijhawm ntev. Yog li ntawd, txheej galvanized solidifies sai sai. Yuav kom ua tiav lub hom phiaj ntawm kev ua kom cov blasting thiab so quab yuam thiab kom du tawm cov kua zinc ntau dhau ntawm cov txheej txheem ze li ntawm galvanized, yuav tsum muaj cov pa loj dua.
(2) Thaum cov yeeb nkab steel galvanized tseem tsis tau nkag mus rau lub nplhaib nozzle qhib, cov pa tawm sai sai thiab tsis tuaj yeem ua kom muaj zog rau saum cov yeeb nkab kawg rau blasting thiab so. Yog li ntawd, lub blasting thiab wiped quab yuam yog tsis txaus, thiab nws yog tsim nyog los ua kom cov roj ntws los kho qhov no. Thaum lub galvanized steel yeeb nkab nkag mus rau lub nozzle lub nplhaib qhib, cov pa roj tau zoo tshuab mus rau sab nrauv ntawm cov yeeb nkab steel galvanized, ua rau kom lub blasting thiab wiped quab yuam. Nyob rau lub sijhawm no, cov roj ntws tuaj yeem raug txo kom tsim nyog.
