Vim li cas acid pickling tsim nyog rau steel tube billets?

Lub hom phiaj ntawm acid pickling steel tube billets yog tshem tawm cov oxide nplai tsim ntawm cov hlau raj nws tus kheej thiab thaum lub sij hawm vuam. Txawm hais tias qee qhov oxide nplai tuaj yeem tev tawm thaum lub strip billet tau zoo li tus, cov hlau uas muaj cov substrate yuav sai sai ua xeb nrog oxygen thiab ya raws hauv huab cua. Yog tias ob hom oxides no tsis raug tshem tawm ua ntej kub-dip galvanizing, lawv yuav tiv thaiv cov tshuaj tiv thaiv ntawm cov hlau substrate thiab cov zinc molten. Yog li ntawd, thaj chaw yuav tsis raug coated nrog zinc, ua rau tsis muaj galvanizing thiab cov pob dub.
