Dab tsi yog qhov cuam tshuam uas cuam tshuam cov haujlwm electrandlating?

Dab tsi muaj xwm txheej cuam tshuam hluav taws xob ua haujlwm?

1. Lub Cathodic tam sim no ceev ntawm cov tshuaj elevelplating muaj cov kev pom zoo tam sim no ceev. Tsis pub dhau cov txheej txheem kev cai tshwj xeeb ntau, ua kom cov Cathodic tam sim no nyob rau hauv lub tshuab hluav taws xob nce ntxiv catherlity polarization, ua rau finer tso cov muaju. Cov nyhuv no yog tshaj tawm thaum Cathodic Polarization yog siab. Txawm li cas los xij, thaum lub Cathodic tam sim no ceev tshaj qhov txwv sab sauv, scorching tuaj yeem tshwm sim ntawm cov ces kaum ntawm workpiece. Yog li ntawd, nruj nreem rau kev ua haujlwm cov txheej txheem thiab cov txheej txheem tseev kom muaj qhov tseem ceeb rau kev ua tiav cov txheej zoo.

2. Kev daws qhov kub yog qhov mob tseem ceeb hauv electroplating. Kev ntsuas ntau dhau los lossis cov tshuaj qis tseem ceeb tuaj yeem cuam tshuam rau cov txheej, yog li nws yog qhov tseem ceeb heev los tswj cov kev daws teeb meem hauv cov txheej txheem qub. Nyob rau hauv ib qho kev mob electroplating, thaum lwm cov txheej txheem cov txheej txheem tseem nyob zoo li qub, txo tus nqi kev siv hluav taws xob, thiab thaum kawg txo qis kev ua haujlwm. Ntau dua cov lus kub siab tuaj yeem ua rau coarser tso cov muaju. Txawm li cas los xij, los ntawm kev kho kom haum nrog nrog lwm cov kev daws teeb meem, thaum tseem ua kom muaj zog ntxiv, thiab thaum kawg nce kev ua tau zoo dua.

3. Txau kev ntxhov siab thiab nplawm tuaj yeem nrawm kev lees paub hauv kev daws teeb meem electroplating thiab txo qis polarization tshwm sim los ntawm canhode kev sib txawv. Cov khoom siv hluav taws xob kev kho mob tsim los ntawm lub tuam txhab tuaj yeem nce Cathode tam sim no, ua tiav cov txheej txheem zoo ntawm qhov siab tam sim no. Agitation hauv cov cuab yeej electroplating tseem tuaj yeem tiv thaiv qhov tsis xws luag xws li cov pits thiab pinholes tshwm sim los ntawm hydrogen khaws cia rau ntawm workpiece nto. Stirringing txoj kev suav nrog cov tshuab stirring, cathode Tsiv kev nplawm, thiab kev ua cua compressed.

4. Daws p yog qhov ntsuas tseem ceeb hauv cov txheej txheem electroplating. Nws tuaj yeem cuam tshuam cov nyhuv hluav taws xob los ntawm kev cuam tshuam rau cov txheej txheem hlau ion thiab cov khoom hluav taws xob. Tsis pub dhau cov khoom lag luam zoo, cov solubility thiab outitional feem pua ​​ntawm cov hlau ions areeasedeased,, thaum tseem txhawb hydrogen tiam thiab txhim kho electroplating efficiency. Yog tias cov pH tsawg dhau, hlau ions yuav precipitate ntawm electrode, sib sau ib txheej insulating, yog li cuam tshuam cov nyhuv electroplilating. Yog tias tus pH yog siab dhau, hlau ions yuav tsim hydroxide precipitates hauv kev daws, kuj cuam tshuam rau cov nyhuv electroplilating. Yog li no, thaum lub sij hawm cov haujlwm electrandating ua haujlwm, cov kev daws teeb meem pH yuav tsum tau sim ua ntu zus thiab kho tau.

5. Lub xub ntiag ntawm impurities tuaj yeem cuam tshuam rau cov nyhuv hluav taws xob. Lub xub ntiag ntawm qee qhov tsis zoo, xws li qee cov organic additives thiab cov neeg sawv cev sib ntxiv, tuaj yeem pab txhim kho tus nqi xa khoom thiab cov hlau ntsig txog hlau. Txawm li cas los xij, qee qhov impurities, xws li hnyav hlau ions thiab ncua cov teeb meem, kuj tseem tuaj yeem cuam tshuam lub electroplating txheej txheem. Cov impurities no tuaj yeem tsim cov txheej insulating rau ntawm electrode, txo qhov ceev tam sim no, lossis daim ntawv suav nrog hauv cov qauv, cuam tshuam rau nws cov qauv thiab cov khoom. Yog li ntawd, nruj kev tswj hwm ntawm lub impurity cov ntsiab lus hauv kev daws teeb meem yog qhov tseem ceeb thaum lub sijhawm electrandating ua haujlwm. Hauv ntej, qhov cuam tshuam ntawm ntau yam yuav tsum tau txiav txim siab txiav txim siab thiab tswj tau zoo thiab tswj lub sijhawm cov haujlwm electroplating. Tsuas yog nyob rau hauv txoj kev no tuaj yeem siab - Zoo incliaglated txheej txheej ua tiav.
