Nyob rau hauv lub tshav pob ntawm electroplatings, yuav tsum tau coated hlau yog yaj nyob rau hauv lub electrolyte, lub plated hlau matrix yog siv raws li ib tug tsis zoo electrode, thiab titanium anode yog siv raws li ib tug zoo electrode, uas ua rau ib tug tag nrho tam sim no kis tau tus mob voj voog. Cov tshuaj tiv thaiv uas tshwm sim ib txhij nrog electroplating hauv lub plating da dej yog nag lossis daus ntawm oxygen rau ntawm qhov chaw ntawm lub anode.
Piv rau cov anodes uas tsis yog-inert xws li graphite, titanium anodes muaj qhov zoo ntawm kev tswj xyuas qhov kev ncua deb ntawm qhov zoo thiab tsis zoo electrodes (nruab nrab ntawm electrodes) rau lub sijhawm ntawm lawv lub neej. Lub graphite anode yuav maj mam yaj hauv kev siv, ua rau muaj kev nce ntxiv ntawm qhov kev ncua deb ntawm cov electrodes, thaum lub inert titanium anode tuaj yeem ua kom ruaj khov voltage thiab khoom zoo. Vim lub catalytic yam ntxwv ntawm platinum pab pawg neeg cov ntsiab lus, qhov sib pauv tam sim no ceev tus nqi ntawm lub electrode nto yog loj, nag lossis daus overpotential ntawm oxygen yog tsawg, thiab cov txheej txheem tshwj xeeb yog siv los ua ib tug zoo qauv oxide zaj duab xis ntawm titanium nto, thiab Qhov chaw ua haujlwm saum npoo yog tau txais ib cheeb tsam electrode, yog li nws yog tshwj xeeb tshaj yog haum rau high-speed thiab high-tam sim no ntom electroplating ntau lawm.
Ntxiv nrog rau titanium anodes thiab graphite, txhuas anodes kuj tseem siv tau rau hauv daim teb no. Txawm li cas los xij, thaum cov hlau lead anode dissolves, nws cov reactants tuaj yeem muaj kev cuam tshuam tsis zoo rau ib puag ncig. Yog tias siv titanium anodes, cov teeb meem no tuaj yeem zam tau. Kev khiav hauj lwm voltage ntawm oxygen evolution titanium anode yog tsawg, uas kuj txuag zog.
Lwm qhov zoo ntawm kev siv titanium anodes yog cov titanium matrix reusable. Thaum lub neej ntawm titanium anodic txheej mus txog nws lub neej muaj txiaj ntsig, anodized aluminium ntawv ci yog cov khoom siv feem ntau siv hauv kev lag luam lithographic. Nws ua haujlwm ntawm tib lub hauv paus ntsiab lus raws li cov txheej txheem electroplating, nrog ib txheej nyias ntawm cov hlau npog rau saum npoo ntawm lub hauv paus hlau. Los ntawm kev tso aluminium rau hauv lub xeev anodic, qhov saum npoo ntawm aluminium oxidizes. Tom qab anodizing (oxidation) txheej txheem ntawm txhuas, qhov saum npoo ntawm txhuas tuaj yeem ua tau zoo dua rau cov txheej txheem photosensitive xav tau hauv kev lag luam lithographic luam ntawv.
Hauv kev lag luam hlau electroplated, anodes yog siv los electroplate ntau yam sib txawv substrates, los ntawm kev tsim cov hniav nyiaj hniav kub hauv cov khoom me me mus rau qhov loj me ntawm cov ntawv hlau plated. Lub tuam txhab cov khoom lag luam anode tau pab ua kom muaj kev sib txawv ntawm cov plating substrate, thiab nws qhov kev sib txawv yog cuam tshuam los ntawm kev sib txawv ntawm lub tuam txhab cov khoom anode.
1. Daim ntawv thov teb: electro galvanizing, precious hlau plating (xws li kub plating, nyiaj plating, palladium plating, thiab lwm yam); Electroplated nyuaj chrome; Nickel plating;
Electro-tin plating (steel phaj tinning).
2. Txheej hom: titanium-raws li ruthenium-iridium, titanium-based iridium-tantalum, titanium-based platinum
3. Kev sib piv nrog cov superiority ntawm txhuas anodes rau pa electroplating
1) Tsawg qhov hluav taws xob thiab siv hluav taws xob tsawg
2) Cov electrode poob tus nqi me me thiab qhov loj yog ruaj khov
3) Cov electrode muaj kev tiv thaiv corrosion zoo, yog insoluble, thiab tsis ua qias neeg da dej, ua rau kev ua tau zoo ntawm txheej txheej txhim khu kev qha.
4) Lub titanium anode txais cov ntaub ntawv tshiab thiab cov qauv, uas txo nws qhov hnyav thiab pab txhawb kev ua haujlwm txhua hnub
5) Lub neej ua haujlwm ntev, thiab cov matrix tuaj yeem rov qab siv tau, txuag nqi
6) Cov pa oxygen evolution overpotential yog hais txog 0.5V qis dua qhov insoluble anode ntawm txhuas alloy, uas txo cov tank voltage thiab txo lub zog noj.
