Platinum-coated Electrodes rau Hydrogen ntau lawm

Titanium anodeyog lub anode nyob rau hauv titanium-raws li hlau oxide txheej. Raws li qhov sib txawv

nto catalytic txheej, nws muaj kev ua haujlwm ntawm oxygen evolution thiab chlorine evolution feem.

Feem ntau, cov khoom siv electrode yuav tsum muaj hluav taws xob zoo, hloov me me ntawm cov ncej

nrug, muaj zog corrosion kuj, zoo mechanical zog thiab kev ua tau zoo, lub neej ntev,

Tus nqi qis, thiab kev ua haujlwm zoo electrocatalytic rau cov tshuaj tiv thaiv electrode. Titanium yog qhov tsim nyog tshaj plaws

rau cov lus saum toj no Cov hlau xav tau yog feem ntau muaj cov ntshiab titanium GR1 lossis GR2.

Kev faib tawm

Soluble anodes thiab insoluble anodes

Soluble anode plays lub luag hauj lwm ntawm supplementing hlau ions thiab ua hluav taws xob thaum lub sij hawm

Cov txheej txheem electrolysis, thaum lub insoluble anode tsuas yog ua lub luag haujlwm ntawm kev ua hluav taws xob. Qhov ntxov tshaj plaws

Insoluble anodes yog graphite thiab lead-based anodes. Hauv xyoo 1970, titanium anodes pib ua

siv nyob rau hauv electrolysis thiab electroplating li tshiab technology. Insoluble anodes tuaj yeem muab faib ua ob

Pawg: chlorine evolution anodes thiab oxygen evolution anodes. Chlorine evolution anode yog

Feem ntau yog siv nyob rau hauv chloride electrolyte systems. Thaum lub sij hawm electroplating txheej txheem, cov anode tso tawm

chlorine gas, yog li nws yog hu ua chlorine evolution anode; oxygen evolution anode feem ntau yog siv rau hauv

sulfate, nitrate, hydrocyanate, thiab lwm yam electrolyte systems. Thaum lub sijhawm ua haujlwm, cov pa oxygen tso tawm

los ntawm cov anode, yog li nws yog hu ua oxygen evolution anode. Lead alloy anodes yog oxygen-evolution

anodes thiab titanium anodes muaj oxygen-evolution, chlorine-evolution zog, los yog ob qho tib si raws li

rau lawv qhov chaw catalytic txheej.

• Titanium anode rau Chlor-alkali kev lag luam

Piv nrog rau graphite electrode, txoj kev diaphragm tsim cov dej qab zib caustic, thiab ua haujlwm.

voltage ntawm graphite anode yog 8A / DM2, uas tuaj yeem ua ob npaug rau 17A / DM2. Ua li no, cov khoom

tuaj yeem muab ob npaug rau hauv ib puag ncig electrolysis, qhov zoo ntawm cov khoom tsim yog

siab thiab purity ntawm chlorine roj yog siab.

• Titanium anode rau electroplating

Insoluble anodes rau electroplating yog coated nrog noble hlau oxide txheej nrog siab

electrochemical catalytic kev ua tau zoo ntawm titanium substrates (mesh, phaj, ribbon, tubular, thiab lwm yam), thiab

lub txheej muaj valve hlau oxides nrog siab stability. Tus tshiab insoluble titanium anode muaj siab

electrochemical catalytic zog, thiab cov pa oxygen evolution overpotential yog li ntawm 0.5 V qis dua qhov ntawd

ntawm cov hlau lead alloy insoluble anode. Cov pa oxygen evolution overpotential ntawm cov tshiab insoluble titanium

anode kuj tseem qis dua li ntawm platinum-plated insoluble anode, tab sis lub neej ncua yog ntau dua.

ua ob npaug. Nws yog dav siv los ua anode lossis auxiliary anode hauv ntau yam electroplating thiab tuaj yeem hloov tau

cov pa txhuas-raws li alloy anode. Nyob rau hauv tib lub sijhawm, nws tuaj yeem txo qhov hluav taws xob ntawm tes thiab txuag

siv zog; insoluble titanium anode muaj kev ruaj ntseg zoo hauv cov txheej txheem electroplating.

(tshuaj, electrochemical), lub neej ua haujlwm ntev. Qhov no anode yog dav siv nyob rau hauv nickel-plated kub-plated,

chrome-plated, zinc-plated, tooj liab-plated, thiab lwm yam electroplating non-ferrous hlau industries.

Cov hlau lead thiab txhuas anodes

Cov hlau lead hlau anode belongs rau oxygen evolution anode, thiab electrolyte rau cov pa oxygen

Cov tshuaj tiv thaiv evolution yog sulfuric acid thiab sulfate, uas yog siv hauv electrolytic metallurgy. Xws li

anodes muaj qhov tsis zoo uas cov geometry yuav hloov thaum lub sij hawm electrolysis. , Thaum lub sij hawm

Cov txheej txheem electrolysis, cov hlau lead anode matrix yog thawj zaug hloov mus rau hauv cov hlau lead sulfate thiab tom qab ntawd mus rau hauv cov hlau lead oxide.

Lead sulfate yog ib qho nruab nrab txheej uas ua raws li cov insulator thiab ua raws li ib tug

chemical barrier los tiv thaiv cov hlau lead matrix ntawm lub puab txheej nyob rau hauv ib puag ncig sulfuric acid.

Lead oxide yog ib qho electrode nyob rau hauv qhov tseeb qhov tseeb nyob rau hauv lub txheej txheej, thiab ib tug oxygen

Cov tshuaj tiv thaiv evolution tshwm sim rau nws. Cov pa oxygen evolution peev xwm ntawm txhuas oxide yog siab heev,

thiab nws nce nrawm nrog qhov nce ntawm qhov ceev tam sim no. Qhov no feature ntawm txhuas alloy anode

yog tias nws yog oxidized los ntawm nws cov khoom txheej txheej. Cov yam ntxwv tseem ceeb ntawm cov hlau lead oxide yog

txiav txim los ntawm tus neeg xyuas pib tsis zoo ntawm hluav taws xob.

Tsis tas li ntawd, thaum lub sij hawm electrolysis, electrochemical kev ua tau zoo ntawm cov hlau lead oxide anode

qauv yog tas li attenuated, thiab tiam ntawm kev ntxhov siab nyob rau hauv ua rau oxide txheej

poob tawm. Tsis tas li ntawd, kev tsim cov hlau lead peroxide kuj ua rau cov oxide tawg tas li,

thiab cov sulfuric acid raws li cov txheej txheem nruab nrab Cov hlau lead yog hloov mus rau hauv cov hlau lead oxide dua thiab

ua ib qho tshiab electrocatalytic active khoom ntawm cov oxide txheej, thiab cov hlau lead matrix ntawm sab hauv

txheej yog oxidized dua los tsim ib tug tshiab intermediate txheej tiv thaiv ntawm txhuas sulfate. Yog li ntawd,

Thaum lub sij hawm electrolysis txheej txheem, txhuas thiab nws cov alloying ntsiab yog txuas ntxiv yaj mus rau hauv lub

electrolyte thiab precipitated, ua rau muaj kuab paug (tshuaj los nag hauv cov kua) thiab

Cov pa phem ntawm cov khoom cathode (electrodeposition ntawm cov pa phem ntawm qhov chaw ntawm cathode, thiab

purity ntawm electrolysis rau tooj liab tsis tuaj yeem siab heev. zoo yog guaranteed).

• Coated Titanium Anode

Coated titanium anode, feem ntau hu ua DSA (Dimensionally Stable Anode), tseem hu ua DSE

(Dimensionally Stable Electrode), yog ib yam tshiab ntawm insoluble anode khoom tsim nyob rau hauv lig

Xyoo 1960s.

DSA-coated titanium anodes yog siv nyob rau hauv electrochemistry thiab electrometallurgy.
