Cov kev paub yooj yim thiab daim ntawv thov ntawm titanium anode
1-titanium anode yog dab tsi?
Cov titanium anode yog hu ua titanium-based hlau oxide coated titanium anode (MMO). Kuj tseem hu ua DSA anode (Dimensionally Stable Anodes) .Nws siv cov titanium ua cov khoom siv rau txhuam thiab txhuam cov xim hlau zoo rau ntawm cov titanium ua kom nws muaj cov electrocatalytic zoo thiab hluav taws xob conductivity.
Titanium anodes tau faib rau cov roj tso tawmfromthe daws bythe anode hauv cov hluav taws xob hluav taws xob. Yog tias nws yog chlorine, peb hu nws tias chlorine evolution anodes, xws li ruthenium-coated titanium electrode.Yog hais tias nws yog oxygen, peb hu nws cov pa oxygen anodes, xws li iridium coated titanium electrode thiab platinum-titanium mesh / phaj anode.
Anode Cov Khoom
Qhov sib cais ntawm roj yog hu ua Chlorine evolution anodes,xws li ruthenium-coated titanium electrode; qhov sib cais ntawm oxidation yog hu ua oxygen evolution anode, xws li iridium coated titanium electrode thiab platinum-titanium mesh / phaj.
Chlorine evolution anodes (ruthenium series coatedtitanium anode): siab Chloride ion muaj nyob hauv cov hluav taws xob, cov khoom muaj nyob hauv hydrochloric acid ib puag ncig thiab cov kua dej electrolytic, ib puag ncig electrolytic ntsev ib puag ncig, xws li ruthenium-iridium titanium anode, ruthenium-iridium tin-titanium anode.
Oxygen evolution anodes (iridiumseriescoated titanium anode): electrolyte feem ntau yog sulfuric acid ib puag ncig. Cov kev siv dav siv iridium tantalum titanium anode, iridium tantalum tin titanium anodeand siab purity iridium coated titanium anode.
Platinum plated titanium anode (Platinumcoatedtitanium mesh / platinum titanium phaj): titanium li cov substrate, plated nrog lub platinum hlau zoo. Lub plating txheej yog 0. 5 - 5 um feem ntau. Qhov txiav txim siab ntawm lub mesh yog 3 * 6 mm, {{4}} * {{{7 {}}} hli thiab 12. {{7 } * 4. 5 hli.
Mmo Mesh Anode Rau Kev Kho Dej Khub
2-Qhov zoo ntawm titanium anode.
Peb cov txheej tshuab yog txhuam.Qhov anodes muaj ntau qhov zoo dua li lwm cov meterial.
1 > Lub dimensionof titanium anode yog qhov ruaj khov thiab qhov kev ncua deb ntawm electrodes tsis hloov thaum lub sijhawm electrolysis, uas tuaj yeem xyuas kom meej tias electrolysis operatio n tuaj yeem nqa nyob hauv qhov xwm txheej ntawm lub tank tsis ruaj khov.
2 > Tsis siv hluav taws xob ua haujlwm tsawg, kev siv hluav taws xob tsawg, kev siv fais fab dc tuaj yeem txo los ntawm 10-20%
3 > Titanium substrate anode muaj cov tshuaj tiv thaiv zoo heev, tuaj yeem ua haujlwm ntev dua.
4 > Piv nrog graphite anode thiab lead dioxide anode, nws tuaj yeem kov yeej txoj kev yaj thaum ua haujlwm. Tsis tas li yuav tsum zam qhov paug ntawm electrolyte, inhance qhov purity ntawm cov khoom lag luam cathodic.
5 > Siab tam sim no ntom ntom, tsis muaj overpotential, siab catalytic kev ua ub no ntawm electrode, tuaj yeem ntes cov khoom lag luam ntau lawm.
6 > Nws tuaj yeem zam luv luv Circuit Court tom qab leaddioxideanode deformation thiab txhim kho kev ua haujlwm tam sim no.
7 > Kev ua lub ntsej muag yog yooj yim thiab tuaj yeem ua nrog qhov siab.
8 > Titanium substrate tuaj yeem rov ua dua tshiab.
9 > Nrog rau cov yam ntxwv overpotential qis, npuas cov nplaim hluav taws xob thiab cov hluav taws xob tau yooj yim tshem tawm, uas tuaj yeem txo qis hluav taws xob ntawm tes hluav taws xob.
Titanium Anode Rau Electrolysis
Hauv kev siv hlau electrolytic, nws tuaj yeem hloov cov pa hlau lead alloy anode, nyob rau hauv tib qho xwm txheej, qhov hluav taws xob tuaj yeem raug txo, thiab lub zog noj yuav txuag tau. Piv txwv li, cov tshuaj electrolysis ntawm zinc ib txwm siv cov hlau lead txhuas qhov muaj cov nyiaj me me, strontium lossis calcium. Itoffen existproblems: cov hlau lead txhuas electrode tsis khov ntawm qhov loj me; cov pa oxygen muaj peev xwm loj dhau (txog 800 mV); corrosion tshwm sim thaum lub anode yog polarized; cov hlau lead ions yog yaj hauv cov electrolyte, tso rau ntawm cathode, paug cov hlau zinc, cuam tshuam rau cov khoom zoo. Titanium anodes rau electrowinning hlau tuaj yeem kov yeej qhov tsis zoo ntawm cov hlau lead anodes, thiab tsim nyog rau kev ua haujlwm siab tam sim no thiab cov ncej nqaim sib txawv rau cov hluav taws xob; tsis tsuas yog rau cov tshuaj sulfate, tab sis kuj tseem siv rau cov tshuaj chlorine ntsev, sulfate thiab chloride sib xyaw tshuab.
