Cold Rolled Steel Phaj yog dov tawm ntawm cov kub dov kauj, feem ntau hais lus, yog kub dov →pickling passivation→ Tus txheej txheem no txias. Txawm hais tias nyob rau hauv cov txheej txheem vim tias yob yuav tseem ua cov hlau phaj kub, tab sis tseem hu ua khaub thuas colled.
Vim yog kub dov tom qab hloov chaw txias ua rau cov khaub thuas dov, hauv cov khoom siv tshuab hluav taws xob tsis zoo, hardness yog siab dhau. Yuav tsum tau faded los rov qab nws cov yam ntxwv yam, tsis muaj fading hu ua cov ntim tawv. Cov dov lub ntim tawv yog feem ntau siv los ua yam uas tsis muaj khoov, ncab cov khoom.
Tab sis cov khaub thuas cold steel phaj filling steel phab ntsa tuab yog qhov ua tau zoo li qub, yog li ntawd cov khaub thuas uas tsis zoo, corrosion kuj yog neeg pluag.
Yog li ntawd, cov khaub noom txias steel feem ntau xaiv los siv cov hlau tsis muaj kev daws teeb meemstainless hlau pickling passivationKev daws teeb meem tuaj yeem ua tau nyob rau hauv tib lub sijhawm kom tshem tawm cov nplaim ntawm cov roj chomium heev ntawm cov hlau. Thaum cov tawv nqaij oxide tau muab tshem tawm, tag nrho cov tshuaj tiv thaiv tau hloov mus ua cov txheej txheem passivation, ua rau muaj kev tiv thaiv busivation. Yuav yog txhua yam ntawm cov roj hlau stainless deg, oxide daim tawv nqaij, thiab muaj qhov tshwm sim ntawm cov zaj duab xis ua yeeb yam, zoo heev txhim kho lub corrosion tsis kam ntawm lub workpiece.
