Electroplating yog txheej txheem uas siv cov txheej txheem electrochemical los npog cov hlau lossis lwm yam khoom ntawm qhov chaw ntawm cov khoom. Los ntawm kev sib koom ua ke ntawm electrolyte, anode, thiab cathode, hlau ions raug txo kom cov hlau ntawm cov cathode los ntawm tam sim no thiab txuas mus rau saum npoo ntawm cov khoom plated, tsim ib qho kev sib txuam, ntom, thiab ua haujlwm tshwj xeeb hlau txheej. Electroplating tshuab tuaj yeem txhim kho cov tsos ntawm cov khoom, nce lawv cov tawv tawv thiab hnav tsis kam, thiab txhim kho lawv cov corrosion kuj.
Cov txheej txheem electroplating muaj xws li chromium plating, tooj liab plating, zinc plating, npib tsib xee plating, thiab lwm yam.
Thiab qhov peb xav qhia ntxiv hauv tsab xov xwm no yog qhov txheej txheem electroplating rau cov khoom flange zoo li cas.
Cov txheej txheem electroplating ntawmflangesyog cov txheej txheem ua ntej kho lub flange nto thiab tso cov hlau ions mus rau lub flange nto los ntawm electrolysis, tsim ib txheej ntawm hlau txheej. Cov txheej txheem electroplating tau muab faib ua ntau hom xws li zinc plating, npib tsib xee plating, chromium plating, thiab lwm yam, uas tuaj yeem xaiv raws li cov khoom siv thiab kev siv ntawm cov flange.
Cov txheej txheem electroplating feem ntau suav nrog cov kauj ruam hauv qab no:
1. Kev ua kom huv hauv qhov chaw: Tshem tawm cov impurities xws li cov roj stains thiab oxides los ntawm flange nto, feem ntau yog siv cov kua qaub thiab alkaline ntxuav kev daws teeb meem.
2. Pretreatment: qhib lub flange nto kom muaj peev xwm khi nrog hlau ions. Acid activators thiab cov tshuaj ua kom muaj zog feem ntau yog siv rau kev kho mob.
3. Electrolytic deposition: Lub flange yog immersed nyob rau hauv ib tug electrolyte uas muaj hlau ions, thiab cov hlau ions raug txo thiab tso rau ntawm qhov chaw ntawm flange los ntawm qhov kev txiav txim ntawm ib tug hluav taws xob tam sim no, tsim ib tug hlau txheej.
4. Tom qab kev kho mob: suav nrog cov kauj ruam xws li kev ua kom txias, yaug, thiab ziab kom zoo thiab du du ntawm cov txheej txheej kawg.
Electroplating tuaj yeem muab tauflange ntocorrosion kuj, hnav tsis kam, zoo nkauj, thiab lwm yam ntxwv, txhim kho kev pab cuam lub neej thiab kev ua tau zoo ntawm flanges. Txawm li cas los xij, kuj tseem muaj qee qhov teeb meem ntawm ib puag ncig cov pa phem thiab cov khoom siv pov tseg thaum lub sij hawm electroplating txheej txheem, uas yuav tsum tau muaj kev tswj kom tsim nyog thiab kev kho mob.
