Platinized anode rau dej electrolysis
1. Daim ntawv thov: acid oxidation tej zaum dej rau ion dej tshuab
2. Khoom specifications: tiav raws li drawings
3 tam sim no ceev: <500A/m2
4. Lub hauv paus ntsiab lus ua haujlwm: lub tshuab hluav taws xob ionized dej ua rau siv lub hauv paus ntsiab lus ntawm dej electrolysis thiab kev xaiv kis tau tus mob ntawm cation exchange membrane rau cation. Nyob rau hauv qhov kev txiav txim ntawm DC hluav taws xob teb, cation txauv membrane yog ntxiv ntawm qhov zoo thiab tsis zoo electrodes los tsim ib tug ob-cell electrolytic cell. Thaum cov dej ntws dhau los ntawm lub cathode ntawm electrolytic cell, qhov concentration ntawm hydroxide ion yog siab, thiab hydrogen tso tawm tib lub sijhawm, uas ua rau cov dej me ntsis yooj yim. Txij li thaum cov tshuaj tiv thaiv electrode yog qhov txo qis thiab cov kev daws teeb meem yog nyob rau hauv lub xeev txo, REDOX muaj peev xwm (ORP) ntawm cov dej tau txais ionized yooj yim yog qhov tsis zoo. Ntawm lub anode, hydrogen ions nrog siab concentration yog generated, tso oxygen. Nyob rau tib lub sijhawm, cov dej muaj cov tshuaj chlorine me me, uas poob cov hluav taws xob thiab tsim cov roj chlorine, yog li ua rau cov dej nplua nuj nyob rau hauv hydrogen ions thiab ib qho me me ntawm cov tshuaj chlorine. Cov tshuaj tiv thaiv electrode yog oxidation cov tshuaj tiv thaiv, cov kua qaub ionized dej yog nyob rau hauv oxidation lub xeev, thiab REDOX peev xwm (ORP) yog zoo.
5. Electrochemical kev ua tau zoo thiab kev kuaj lub neej (saib HG/T2471-2007 Q/CLTN-2012)

Ionic dej kev lag luam tus qauv yog alkaline txo cov dej pH nqi 7. muaj zog qhov txo qis, qhov zoo ntawm cov dej zoo. Acidic txo dej pH tus nqi yog 2.5-6.5, ORP Ntau dua lossis sib npaug ntawm 300mV, qhov qis pH tus nqi hauv cov qauv, qhov zoo dua, qhov siab dua ORP, lub zog txo qis, qhov zoo dua dej zoo. Nws tuaj yeem pom los ntawm lub rooj hais tias cov dej zoo ntawm cov dej ionic tsim los ntawm cov tsim Pt / Ti electrode ua tau raws li cov qauv kev lag luam ntawm cov dej ionic, thiab cov dej ua tau zoo ntawm cov dej ionic uas tsim los ntawm Pt / Ti electrode zoo dua. tshaj qhov uas ua los ntawm titan-based MMO electrode.
7.Platinum yog dav siv nyob rau hauv electroplating, electrolytic synthesis, electrochemical kev kho cov dej khib nyiab thiab roj hlwb, thiab lwm yam. Platinum electrodes yog yus muaj zog corrosion kuj, siab catalytic kev ua si, siab oxygen evolution muaj peev xwm thiab tsawg hydrogen evolution muaj peev xwm. Nws tsis yog tsuas yog cov khoom siv anode nrog kev ua haujlwm zoo, tab sis kuj yog cov khoom siv cathode nrog kev ua tau zoo heev. Tsuas yog qee cov kua qaub sib xyaw, platinum pom zoo corrosion kuj nyob rau hauv hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, phosphoric acid thiab feem ntau cov tshuaj electrolyte. Ntau yam tseem ceeb hauv kev lag luam electrochemical, xws li hydrogen peroxide, ammonium persulfate, dej electrolysis tuaj yeem siv los ua cov khoom siv anode. Txawm li cas los xij, cov peev txheej platinum tsis tshua muaj thiab kim, tshwj xeeb tshaj yog cov khoom siv hluav taws xob siv hauv kev lag luam yog qhov loj, yog li nws tsis tuaj yeem siv cov ntshiab platinum anode ncaj qha rau hauv kev tsim khoom, uas txwv tsis pub nrov thiab siv platinum electrode hauv kev lag luam electrochemical. Txhawm rau txuag cov nqi hluav taws xob thiab cov khoom siv platinum, nws yog ib qho tsim nyog yuav tsum siv titanium raws li platinum anode es tsis txhob ntawm cov ntshiab platinum anode. Tam sim no, titanium matrix platinum anode tsuas yog siv P ntsev electroplating txheej txheem. Cov teeb meem tseem ceeb ntawm cov txheej txheem no yog cov khib nyiab loj ntawm cov tshuaj electroplating, tus nqi siab, thiab kev sib khi tsis zoo ntawm plating platinum txheej.
Peb lub tuam txhab tau tsim cov txheej txheem thev naus laus zis ntawm platinum txheej, uas muaj qhov zoo ntawm cov nqi qis, kev tsim khoom yooj yim thiab kev sib txuas lus zoo
Lub sintered PT electrode tau zoo conductivity thiab ntxiv dag zog rau lub neej tshaj li imported Pt - plated Ti electrode. Cov txiaj ntsig kev sim qhia tau hais tias cov nyhuv electrolytic zoo dua li Ruthenium-iridium txheej, uas tuaj yeem tau alkaline ionized dej nrog pH siab tshaj 9.5, acidic ionized dej nrog ORP saum toj no -250mV thiab pH 3-4.
