Yuav ua li cas xaiv cov kev ua teeb meem nyuaj hauv kev ua electroplating ua? Dab tsi yog qhov sib txawv ntawm cov teeb meem sib txawv?

Kev nyuaj rau hauv electroplating: xaiv thiab sib txawv

Electroplating yog txheej txheem uas tso cov hlau lossis alloy txheej ntawm ib qho txheej txheem los ntawm cov hau kev electrochemical. Nws yog dav siv nyob rau hauv kev zoo nkauj, corrosion - tiv taus, hnav {{2} {resistant, thiab kev siv cov ntawv thov. Txawm li cas los xij, hauv kev tsim tiag, electroplating feem ntau ntsib ntau yam nyuaj uas cuam tshuam cov khoom zoo, kev ua tau zoo, thiab tswj kev tswj hwm. Yog li ntawd, yuav ua li cas xaiv thiab daws cov teeb meem no ua qhov teeb meem tseem ceeb hauv electroplating. Kab lus no yuav tshuaj xyuas cov teeb meem uas elotlating, txheeb xyuas lawv qhov sib txawv, thiab daws lawv cov tswv yim.

I. Cov teeb meem uas nyuaj hauv electroplating

1. Kev xaiv substrate thiab pretreatment

Kev xaiv substrate thiab kev ua tiav yog thawj cov nyom hauv electroplating. Txawv cov txheej txheem (xws li hlau, tooj liab, txhuas, thiab yas) sib txawv, thiab cov txheej txheem kev ua kom zoo nkauj, cuam tshuam nrog cov txheej electroplated. Piv txwv li, steel substrates yog nquag mus xeb, txhuas substrates yog nquag ua yeeb yaj kiab oxide thiab yas substrates raug kev txom nyem los ntawm cov khoom muaj zog thiab tsis muaj zog.

Qhov sib txawv:

{{0- steel subtrates: nto teev, roj, thiab xeb yuav tsum tau muab tshem tawm, feem ntau siv cov hau kev xws li ntxuav, lossis kev siv tshuab polishing.

{{0-} Aluminium substrates: vim tias cov duab xim tuab xws li cov txheej txheem tshwj xeeb zoo li cov tshuaj tshwj xeeb lossis anodizing yuav tsum muaj.

-} Lub zog yas ntxiv: Lub zog saum npoo yuav tsum tau nce ntxiv thiab kev kho tshuaj etching, lossis ntshav kho mob.

2. Electroplating daws teeb meem kev tswj hwm thiab txij nkawm

Cov qauv tsim ntawm cov kev daws teeb meem electroplating ncaj qha cuam tshuam qhov zoo ntawm txheej. Cov tsis muaj xws li ntsev loj, ntxiv, pH, pH, pH, hauv lub electroplating daws yuav tsum tau tswj kom ncaj. Tsis tas li ntawd, cov kev daws teeb meem electroplate tuaj yeem maj mam dhau los ua qhov tsis xws luag xws li pinholes, pitting, thiab blister nyob rau hauv txheej.

Qhov sib txawv:

- Cov Hniav Hluav Taws Xob (xws li chrome plating thiab cov nickel plating thiab cov khoom sib xyaw ua ke, xav tau cov kev sib xyaw ua ke, xav tau kev sib xyaw ua ke, xav tau kev sib xyaw ua ke, xav tau kev sib xyaw ua ke, xav tau kev sib xyaw ua ke, xav tau cov kev sib xyaw ua ke, xav tau kev sib ntxiv, yuav tsum tau ua ib qho ntxiv ntawm cov neeg sawv cev ntawm cov hluav taws xob thiab theem ntsuas hluav taws xob.

-}}}}}}} Ua haujlwm electroplating (xws li zinc thiab plating): Ua ntej rau corrosion tsis kam thiab kev coj ua ntawm cov txheej. Cov txheej txheem daws teeb meem yooj yim, tab sis nws yog rhiab rau impurities.

3. Tam sim no ceev thiab coating Thickness tswj

Ceev tam sim no yog qhov tseem ceeb cuam tshuam rau cov txheej txheem zoo. Kev nrawm dua tam sim no tuaj yeem ua rau muaj cov xim ntxhib thiab hluav taws xob; Tsis tshua muaj ntom ntom ntom tso nyiaj ntxiv thiab tuaj yeem tiv thaiv cov txheej txheej sib dhos. Tsis tas li ntawd, kev tswj txheej txheej tuab yog qhov nyuaj. Dhau dhau lawm yuav ua rau muaj cov khoom tiv thaiv tsis txaus, thaum cov tuab tuab dhau toj thiab yuav ua rau muaj kev ntxhov siab tawg.

Qhov sib txawv:

{{0 {0} high tam sim no ceev intrasspleccing: tsim nyog rau kev kho kom sai, tab sis kev saib xyuas yuav tsum tau coj los tiv thaiv kev ntsuas lossis kev ua kom pom tseeb.

4. Txheej - rau -} Substrate Adhesion

Txheej - rau -} Substrate Adhesion yog qhov taw qhia tseem ceeb ntawm cov khoom lag luam hauv hluav taws xob. Cov nplaum tsis txaus tuaj yeem ua rau muaj teeb meem xws li ya thiab tawg. Cov xwm txheej cuam tshuam rau cov adhesion xws li substrate mob txawv, pretreatment txheej txheem, plating daws cov tshuaj muaj pes tsawg leeg, thiab plating tsis sib xws.

Qhov sib txawv:

- pa} hlau substrates: adhesion tau txiav txim siab los ntawm qhov kev nyiam huv thiab ua ntej.

- Kuv tsis yog- pa taws (xws li cov txheej txheem sib xyaw ua ke, qhov zoo ntawm cov txheej txheem conductive, thiab txheej txheem plating.

5. Ib puag ncig thiab kev nyab xeeb teeb meem

Cov txheej txheem hluav taws xob koom nrog ntau yam tshuaj, alkalis, thiab cov kav dej hlau hnyav, uas tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv. Yog li ntawd, ib puag ncig thiab kev nyab xeeb teeb meem muaj cov nyom tseem ceeb hauv electroplating.

Qhov sib txawv:
