Ua ntej, hom kev kho mob saum npoo:
Kev kho saum npoo av yog txheej txheem ntawm kev ua cov txheej txheej nyob rau saum npoo ntawm kev ua haujlwm los ntawm qee txoj kev. Lub hom phiaj ntawm cov txheej txheem saum npoo yog muab cov khoom saum npoo ntawm qhov zoo nkauj thiab tiv thaiv xeb. Cov txheej txheem kev kho saum npoo yog ntaus nqi rau cov hau kev hauv qab no:
1. Kev Siv Hluav Taws Xob: Cov roj electroplated tau muab tso rau hauv cov kua aqueous uas muaj cov ntawv tso ua hlau, thiab cov hluav taws xob hluav taws xob dhau los ntawm cov hlau plating ua rau cov hlau electroplated yuav tsum tso thiab tso nyiaj rau ntawm cov khoom tiv. Feem ntau, electroplating suav nrog galvanizing, tooj liab, npib tsib xee, chromium, tooj-nickel alloy, thiab lwm yam.
Qee zaum hauv paus dub (xiav), phosphating, thiab lwm yam.
2. Kub duav galvanizing: Qhov no tau ua tiav los ntawm kev ua kom cov pa roj carbon steel sib xyaw rau hauv lub plating da dej ntawm molten zinc ntawm qhov kub txog 510 ° C. Qhov tshwm sim yog hais tias cov hlau-zinc alloy nyob rau saum npoo ntawm steel daim maj mam dhau los ua passivated zinc ntawm lub npoo sab nraud ntawm cov khoom. Kub dip aluminizing yog cov txheej txheem sib xws.
3. Neeg kho tshuab plating: Qhov saum npoo ntawm cov khoom yog cuam tshuam los ntawm cov xim hlau tsis sib xyaw thiab txheej txheej txias txias txuas rau saum npoo ntawm cov khoom.
