Kev tsom xam luv luv ntawm titanium anode txheej
Titanium electrode yog electrochemical electrode feem ntau yog ua los ntawm ntshiab titanium los yog titanium alloy. Lawv tau siv dav hauv kev lag luam electrochemistry, piv txwv li hauv cov txheej txheem electrolysis, kev tshawb fawb corrosion, electrodeposition, dej kho, electrochemical tsom xam thiab lwm yam kev siv. Txawm li cas los xij, qhov chaw ntawm titanium electrodes raug oxidized yooj yim, ua rau tsim titanium dioxide (TiO2) ntawm qhov chaw thiab txo nws cov electrochemical kev ua si. Yuav kom kov yeej qhov teeb meem no, titanium electrodes yog coated nrog ntau hom ntaub ntawv xws li platinum, ruthenium, iridium, titanium nitride, thiab sib xyaw hlau oxides los txhim kho lawv cov electrochemical kev ua si thiab durability. Coatings kuj pab txhim kho cov kev xaiv thiab kev ruaj ntseg ntawm electrodes rau cov tshuaj tiv thaiv tshwj xeeb kom haum rau cov kev xav tau tshwj xeeb.
Lub hom phiaj ntawm txheej txheej muaj xws li hauv qab no:
1. Txhim kho cov kev ua haujlwm ntawm electrocatalytic ntawm electrode: Los ntawm kev ua kom cov catalyst ntawm lub electrode nto, cov catalytic kev ua ntawm cov electrode tuaj yeem txhim kho thiab cov tshuaj tiv thaiv electrochemical tuaj yeem txhawb nqa.
2. Ua kom cov corrosion kuj ntawm cov electrode: Titanium electrode nws tus kheej muaj corrosion kuj zoo, tab sis nyob rau hauv tej qhov chaw huab cua, nws tseem yuav corroded. Yog li ntawd, cov txheej txheem tuaj yeem ua rau muaj kev tiv thaiv corrosion ntawm electrode.
3. Txhim kho txoj kev sib hloov electrode: Cov txheej txheej tuaj yeem xaiv qhov ua tau zoo ntawm qee qhov kev cuam tshuam thiab txo qis lwm yam tsis xav tau.
4. Txhim kho qhov conductivity ntawm electrode: Cov txheej txheej tuaj yeem txhim kho cov conductivity ntawm cov electrode kom ntseeg tau tias tam sim no tuaj yeem sib npaug sib npaug ntawm tag nrho cov electrode nto.
Cov txheej tsis sib xws tuaj yeem ua rau electrode kev ua haujlwm tsis zoo li qhov xav tau, yog li cov hauv qab no yuav tsum tau sau tseg:
Ntshiab huv: Ua ntej txheej, nws yog ib qho tsim nyog los xyuas kom meej tias cov electrode nto huv si thiab tsis tas yuav tsum tau hloov los yog hloov. Pickling, electrostatic tu thiab lwm txoj kev feem ntau yog siv los ntxuav qhov chaw.
Tswj txheej txheej thickness: Lub thickness ntawm txheej yuav tsum tau tswj kom zoo ib yam kev faib tawm ntawm tag nrho cov electrode nto. Nws yog feem ntau ua tiav los ntawm kev txau, dipping lossis electrodeposition.
Xaiv cov khoom txheej txheej zoo: Xaiv cov khoom txheej txheej kom ua tau raws li qhov xav tau ntawm koj daim ntawv thov tshwj xeeb. Feem ntau siv cov ntaub ntawv txheej xws li platinum, kub, rubidium oxide, thiab lwm yam.
Tswj txheej txheem txheej txheem tsis: Hauv txheej txheej txheej txheej, nws yog ib qho tsim nyog los tswj cov txheej txheem txheej txheej, xws li qhov kub, qhov siab, lub sijhawm, thiab lwm yam.
Kev tshuaj xyuas zoo: Tom qab txheej txheej, kev tshuaj xyuas zoo feem ntau yuav tsum tau ua, xws li kev sim, tshuaj ntsuam xyuas electron microscopy, thiab lwm yam, kom ntseeg tau tias txheej txheej zoo tsim nyog.
Txhua lub sij hawm tom qab satin raug rho tawm haujlwm, nws yuav tsum raug yuam kom txias rau chav tsev kub ua ntej txheej tom ntej tuaj yeem siv tau, txwv tsis pub cov txheej yuav tsis zoo ib yam.
Cov txheej txheej ntawm lub substrate yog coated ntau zaus. Thawj txheej ntawm txheej txheej yog qhov ntxeem tau. Thaum cov txheej txheej yog thov, cov cua kub-kho cov pa tuaj yeem dhau los ntawm cov txheej txheem ntxeem tau thiab ua rau cov hlau ntsev nyob hauv qab txheej. Nyob rau hauv txoj kev no, lub porosity ntawm generated oxide txheej txo qis raws li tus naj npawb ntawm coatings nce. Kev ua haujlwm ntawm txheej txheej, ziab, thiab thermal oxidation yog rov ua dua kom txog thaum cov kua txheej yog siv tag.
Tom qab thermal oxidation, xyuas cov titanium anode tiav: so nws nrog cov ntawv lim, thiab tsis muaj cov xim dub pom tseeb ntawm daim ntawv lim, qhia tias cov txheej thiab cov substrate tau ruaj khov; so nws nrog cov ntawv lim, thiab pom tias muaj cov xim dub pom tseeb, qhia tias Xu txheej raug tshem tawm tiag tiag. Yog vim li cas: Kev kho cua sov yog tsawg; cov kua txheej yog siv tuab heev txhua zaus; Tom qab calcining, titanium anode tsis txias rau chav tsev kub thiab cov kua txheej yog siv dua. Yog hais tias titanium anode hloov xiav, nws yuav tshwm sim los ntawm thermal oxidation kub siab dhau lawm.
Txheej txheej txheej xaiv rau titanium electrodes yuav txawv nyob ntawm seb cov ntawv thov tshwj xeeb thiab cov khoom siv, thiab feem ntau yuav tsum tau kho raws li qhov xwm txheej. Cov txheej txheem txheej txheej feem ntau suav nrog lub cev vapor deposition, txoj kev daws teeb meem, electrochemical deposition, thiab lwm yam. Cov txheej txheem tsis thiab cov kauj ruam yuav nyob ntawm qhov txheej txheem txheej txheej. Kho thiab optimize txheej txheej txheem thiab xav tau kev ua tau zoo.
Hauv cov ntsiab lus, txheej txheej yog qhov tseem ceeb los txhim kho kev ua haujlwm ntawm electrochemical ntawm titanium electrodes. Txhawm rau ua kom pom kev ua tau zoo, nws yog ib qho tseem ceeb uas yuav tsum tau tsom mus rau qhov zoo ntawm cov txheej, nrog rau kev sib xws, kev pab them nqi thiab thickness. Tsim nyog kev ntsuas yuav tsum tau coj los ua cov txheej txheem txheej txheej thiab tsim nyog tswj kev tswj hwm zoo yuav tsum tau ua kom ntseeg tau cov txheej txheej zoo.
