Cov yeeb nkab steel tau ua raws li kev kho mob nyob rau hauv ib qho acid da dej nrog tsawg concentration tab sis siab hlau ntsev cov ntsiab lus. Thaum lub sijhawm no, cov kua qaub ntsuas kub tuaj yeem nce siab kom tshem tawm cov roj seem thiab impurities ntawm cov yeeb nkab nto. Thib ob, nyob rau hauv qhov siab -kub acid da dej, tuab hlau oxide nplai dissolves sai dua, ua kom yooj yim hydrogen diffusion mus rau hauv cov yeeb nkab substrate los tsim cov roj chlorine. Raws li hydrogen khiav tawm, nws ua rau cov hlau oxide detach. Thib peb, txij li qhov tseem ceeb ntawm cov hlau oxide nplai thiab lwm yam kab mob tseem nyob hauv chav da dej ua ntej, qhov no ua kom huv si ntawm cov kua qaub da dej hauv theem kawg ntawm kev kho cov kua qaub.
