Yuav ua li cas xaiv cov kev ua qauv rau cov electroplating? Dab tsi yog qhov sib txawv ntawm cov tsis sib xws?
Tso lus
Electroplating yog txheej txheem uas tso nyiaj hlau los yog alloys ntawm substrates los ntawm cov hau kev electrochemical. Nws yog dav siv nyob rau hauv electronics, Automotive, Aerospace, thiab Machinery raug. Kev xaiv ntawm electroplating elegeters ncaj qha cuam tshuam cov kev cuam tshuam zoo, kev ua tau zoo, thiab ntau lawm kev ua haujlwm ntawm cov txheej. Cov ntsiab lus hauv qab no qhov tseem ceeb electropers thiab lawv cov qauv kev xaiv, raws li tau tshuaj xyuas qhov cuam tshuam ntawm cov qhab nia sib txawv ntawm cov qhabnias hluav taws xob.
1. Electroplating daws cov tshuaj
Cov txheej txheem hauv hluav taws xob yog qhov tseem ceeb ntawm cov txheej txheem electroplating, thiab nws txoj kev muaj pes tsawg leeg cuam tshuam rau qhov zoo thiab ua tau zoo ntawm txheej. Cov kev daws teeb meem hluav taws xob feem ntau suav nrog cov neeg muaj tswv yim tseem ceeb, cov ntsev ua tau, cov nplauv, thiab ntxiv.
- Cov ntsev tseem zoo: Cov no muab cov hlau ions, xws li tooj liab sulfate thiab Nickel chloride. Qhov kev xav ntawm cov neeg muaj kev cuam tshuam loj cuam tshuam cov nqi thauj khoom thiab cov kev sib dhos ntawm txheej. Kev txiav txim siab ntau dhau tuaj yeem ua rau txheej txheej ntxhib, thaum lub sijhawm qis zuj zus tuaj yeem qeeb tus nqi tso nyiaj qeeb.
