Yuav ua li cas Electroplating txhim kho cov khoom muaj kev ntseeg tau? Dab tsi cov txheej txheem tuaj yeem txhim kho cov khoom lag luam ruaj khov?

Electroplating yog txheej txheem uas siv cov electrolysis kom tso ib lossis ntau txheej ntawm cov hlau lossis alloy rau ntawm cov hlau lossis tsis - hlau cov npoo. Nws yog dav siv nyob rau hauv electronics, machinery, automotive, Aerospace, thiab lwm thaj teb. Electroplating tuaj yeem tshem tawm corrosion tsis kam, kev coj tawm tsam, thiab kho kom zoo nkauj rau kev txhim kho cov khoom muaj kev cia siab thiab kev ruaj khov.

I. Npaum li cas thiaj siv hluav taws xob cov khoom muaj kev ntseeg tau?

1. Txhim kho corrosion resistance: electroplating tuaj yeem cais cov txheej txheem los ntawm kev tawm tswv yim, xeb, yog li muaj cov khoom lag luam, yog li ntau zuj zus khoom siv nyiaj txiag lithespan thiab kev ntseeg tau. Piv txwv li, zinc thiab npib npib tsib xee ntawm cov chaw tsheb tuaj yeem tiv thaiv cov xeb hauv cov chaw puag ncig huab.

2. Txhim kho cov hnav tsis kam: electroplilating tuaj yeem nce lub hardness thiab hnav tsis kam ntawm substrate sab, txo kev sib txhuam thiab hnav, thiab nthuav cov khoom lag luam lub neej. Piv txwv li, nyuaj chrome plating rau pwm tuaj yeem txhim kho nws cov hnav tsis kam thiab kev pabcuam lub neej.

3. Txhim kho kev ua haujlwm: electroplilating tuaj yeem nce cov txheej txheem txheej txheem, txo kev sib chwv tiv thaiv, thiab txhim kho cov khoom lag luam hluav taws xob. Piv txwv li, kub lossis nyiaj plating rau ntawm Cheebtsam hluav taws xob tuaj yeem txhim kho lawv kev coj ua thiab kev ntseeg tau.

4. Txhim kho kev kho kom zoo nkauj: electroplating tuaj yeem muab cov xim sib txawv thiab sheen mus rau substrate, txhim kho lub loog thiab ntxiv cov txiaj ntsig ntawm cov khoom. Piv txwv li, kub lossis nyiaj plating rau cov hniav nyiaj hniav kub thiab cov khoom siv tuav tuaj yeem txhim kho kev kho kom zoo nkauj thiab tus nqi ntawm cov khoom.

Ii. Cov txheej txheem twg tuaj yeem txhim kho cov khoom lag luam ruaj khov?

Yuav kom ua tiav siab - Zoo, ruaj khov Electroplated txheej, txheej txheem txhim kho thiab kev tswj hwm yog qhov tsim nyog hauv cov chaw hauv qab no:

1. PretReatment:

Degreasing: kom huv si tshem cov roj, roj, thiab lwm yam paug los ntawm txheej sib raug zoo ntawm cov txheej hluav taws xob ntawm cov txheej electroplated thiab lub substrate.

Rust tshem tawm: Tshem tawm cov nplai thiab xeb los ntawm substrate saum npoo kom tiv thaiv kev txwv ntawm cov txheej electroplated.

Ua kom: Tshem tawm cov yeeb yaj kiab oxide ntawm cov chaw ua si sab nraud, txhim kho cov kev ua si substrate, thiab txhawb nqa cov txheej txheem ntawm electropcrated.

2. Tswj cov txheej txheem electroplating:

Ntsej ceev tam sim no: Tswj cov ntawv tso tawm mus thiab tuab ntawm cov txheej electroplated kom tsis txhob muaj qhov tsis xws luag xws li scorching thiab pinholes.

Qhov kub thiab txias: tswj qhov kub ntawm electroplating kev daws teeb meem cuam tshuam cov crystal morphology thiab cov khoom ntawm cov txheej electroplated.

PH: Tswj cov ph ntawm cov kev daws teeb meem electroplating cuam tshuam cov muaj pes tsawg leeg thiab cov khoom ntawm cov txheej electroplated.

Cov tshuaj ntxiv: Ntxiv cov quav ntxiv tuaj yeem txhim kho cov siv lead ua kom zoo nkauj, ci, thiab cov txheej txheem ntawm cov txheej electroplated.

3. Post -} cov txheej txheem kho:

Ntxuav: kom huv si muab cov txheej txheej plating cov plating los ntawm qhov chaw ntawm electroplated ib feem los tiv thaiv corrosion thiab paug.

Kom qhuav: meej qhuav lub electroplated ib feem kom tiv thaiv xeb thiab discoloration.

Hla: passivating qee cov txheej electroplated tuaj yeem txhim kho lawv cov corrosion tsis kam.

III. Piv txwv ntawm cov txheej txheem tshwj xeeb txhim kho cov khoom lag luam ruaj khov:

Cyanide -} dawb electroplating: Tsoos Kev Ua Ntej Electroplating cov txheej txheem feem ntau siv cov cyanide ua ib tus neeg sawv cev sib luag. Txawm li cas los xij, cyanide yog cov tshuaj lom tau heev thiab ua tus yuav phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv. Cyanide - dawb electroplaps elecication lossis qis {{4 4} {{4 4} {{4 4} {{4 4} {{4 4} {{4 4} Kev ua phooj ywg ib puag ncig thiab kev ruaj ntseg ntawm cov khoom.

Mem tes plating: Mem Tes Plating siv tam sim no los yog voltage Wavefated, txhim kho nws qhov ceev, thiab corrosion tsis kam, yog li kev txhim kho cov khoom ruaj khov.

Composite plating: Composite plating yuav ntxiv cov khoom siv ntxiv rau cov plating daws, tso cai rau co {} tso nrog hlau ions los ua cov txheej txheem sib xyaw. Composite cov txheej txheem tuaj yeem npaj siab dua hardness, thiab corrosion tsis kam rau substrate, li kev txhim kho khoom ruaj thiab kev pabcuam lub neej.

IV. Ntsiab lus:

Electroplating yog qhov tseem ceeb txhais tau tias ntawm kev txhim kho cov khoom muaj kev ntseeg tau thiab ruaj khov. Los ntawm kev ua kom zoo ua ntej - kev kho, ua tiav cov khoom lag luam, thiab cov khoom siv hluav taws xob, txuas ntxiv nws lub neej kev ua lag luam thiab txhim kho nws txoj kev sib tw ua lag luam. Nyob rau hauv lub neej yav tom ntej, nrog thev naus laus zis, muaj ntau puag ncig ua ke, muab cov khoom lag luam hluav taws xob ruaj khov, muab cov khoom lag luam hluav taws xob ruaj khov, muab cov khoom lag luam zoo dua thiab cov kev pabcuam rau ntau yam kev lag luam.
