Cov kua qaub pickling ntawm steel yeeb nkab blanks pab tshem tawm cov hlau oxide nplai tsim thaum lub sij hawm tsim cov yeeb nkab thiab vuam. Txawm hais tias qee qhov nplai tuaj yeem flake tawm thaum lub sij hawm shaping, lub hauv paus hlau raug xeb sai sai thaum raug huab cua thiab ya raws. Yog tias cov oxides tseem tsis tau tshem tawm ua ntej kub -dip galvanizing, lawv yuav cuam tshuam cov tshuaj tiv thaiv ntawm cov hlau substrate thiab zinc molten, uas ua rau cov zinc txheej tsis tiav thiab cov pob dub tshwm sim los ntawm cov chaw tsis muaj txheej txheem.
