Cov txheej txheem electroplatingyog ib txoj kev ntawm txheej ib tug neeg xyuas pib nrog ib txheej ntawm hlau siv lub hauv paus ntsiab lus ntawm electrolysis.Electroplating yog hais txog kev ua txheej txheem saum npoo uas lub hauv paus hlau yuav tsum tau plated yog siv los ua cov cathode hauv cov tshuaj ntsev uas muaj cov hlau ua ntej-plated, thiab cov cations ntawm cov hlau pre-plated nyob rau hauv cov tshuaj plating yog tso rau ntawm qhov chaw. puag hlau los ntawm electrolysis los tsim ib txheej.
Cov khoom ntawm cov txheej yog txawv ntawm cov hlau puag thiab muaj cov yam ntxwv tshiab.Raws li kev ua haujlwm ntawm cov txheej txheem, nws tau muab faib ua cov txheej txheem tiv thaiv, cov txheej txheem zoo nkauj thiab lwm yam txheej txheem ua haujlwm.
Thaum lub sij hawm electroplating, plated hlau los yog lwm yam insoluble khoom yog siv raws li anode, lub workpiece yuav plated yog siv raws li cathode, thiab cov cations ntawm cov hlau plated raug txo rau saum npoo ntawm lub workpiece yuav plated los ua ib tug plated txheej. .Nws tuaj yeem txhim kho corrosion kuj ntawm cov hlau (cov hlau txheej yog feem ntau corrosion-resistant hlau), nce hardness, tiv thaiv hnav, txhim kho conductivity, smoothness, kub tsis kam thiab nto zoo nkauj.
Tseem ceeb
Electroplatingyog cov txheej txheem electrochemical nrog rau cov txheej txheem redox.Cov txheej txheem yooj yim ntawm electroplating yog raus rau hauv ib qho kev daws ntawm cov ntsev ntsev raws li cathode, cov phaj hlau ua cov anode,atom qab lub DC lub hwj chim qhib, cov txheej xav tau muab tso rau ntawm qhov chaw.
CraftingProcess
Feem ntau, nws suav nrog peb theem ntawm pre-plating pretreatment, electroplating thiab tom qab plating kev kho mob.
Ua tiav cov txheej txheem: 1. Pickling → tag nrho phaj electroplating
Copper → qauv hloov → acid degreasing → Secondary countercurrent rinsing → micro-etching → Secondary → pickling → tin plating → Secondary countercurrent rinsing 2, countercurrent rinsing → pickling → qauv tooj liab plating → Secondary countercurrent rinsing → npib tsib xee plating → immersion theem 2 citric acid → kub plating → recycling → theem 2-3 ntxuav dej ntshiab → ziab.
