Platinum-raws li txheej
Anode rau dej electrolysis yog siv hauv kev lag luam.
50-200 A / m2 ntawm qhov ceev tam sim no
Keeb kwm thiab kev taw qhia txog kev siv cov khoom siv: Platinum yog cov khoom siv hluav taws xob uas siv hauv electroplating, electrolytic synthesis, kev kho dej khib nyiab, roj hlwb, thiab lwm yam kev siv. Platinum electrodes muaj corrosion kuj zoo, siab catalytic kev ua si, thiab yog heev resistant rau oxidation, siab oxygen evolution muaj peev xwm, tsis tshua muaj hydrogen evolution muaj peev xwm, thiab lwm yam ntxwv yog ob qho tib si kev ua tau zoo ntawm cov khoom siv anode, tab sis kuj muaj kev ua tau zoo ntawm cov khoom siv cathode. Platinum nthuav tawm zoo corrosion kuj nyob rau hauv hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, phosphoric acid, thiab feem ntau ntawm electrolyte daws, tshwj xeeb tshaj yog ob peb tov acids. Hydrogen peroxide, ammonium persulfate, dej electrolyzed, thiab lwm yam tseem ceeb hauv kev lag luam electrochemical domains tuaj yeem ua haujlwm ua cov khoom siv anode. Txawm li cas los xij, kev nce qib thiab kev siv platinum electrodes hauv electrochemical sector raug txwv los ntawm qhov tsis txaus thiab tus nqi siab ntawm platinum cov peev txheej, uas ua rau muaj qhov tsis zoo los ntawm ntau cov khoom siv hluav taws xob siv hauv kev lag luam. Nws yog ib qho tseem ceeb uas yuav tsum tau siv lub titanium-raws li platinum anode nyob rau hauv qhov chaw ntawm cov ntshiab platinum anode thiaj li yuav txo tau tus nqi ntawm cov electrode thiab txuag platinum kev pab cuam; Tam sim no, titanium-raws li platinum anode feem ntau yog, thiab lub zog sib txuas ntawm electroplating platinum hlau platinum txheej tsis zoo.
Cov txheej txheej platinum txheej tshuab uas peb lub tuam txhab tau tsim muaj cov txiaj ntsig ntawm tus nqi qis, cov txheej txheem tsim khoom ncaj nraim, thiab kev tswj hwm kev sib raug zoo. Tsis tas li ntawd, sintered platinum electrodes muaj kev ua tau zoo dua qub thiab lub neej ntev dua li titanium electrodes uas tau raug xa tawm nrog platinum plating. Hauv kev sim, nws tau pom tias cov nyhuv electrolysis zoo dua li ntawm ruthenium-iridium txheej thiab cov dej alkaline ionized nrog pH ntawm 9.5 lossis ntau dua, acidic ionized dej nrog ORP ntau dua -250mv, thiab pH qib ntawm 3 txog 4, tuaj yeem tau txais ob qho tib si.
Muaj txiaj ntsig:
1. Khaws cov pH ntawm cov dej acidic qis dua 2.5 thiab pH ntawm cov dej alkaline siab tshaj 8.5, ORP tus nqi ntawm cov dej alkaline tsawg dua -250 mV, thiab cov dej acidic ntau dua 1000 mV;
2. Muaj ntau tshaj 3000 teev;
3. Tus nqi qis thiab cov txheej txheem tsim khoom yooj yim;
4. Muaj peev xwm oxygen evolution, Ntau dua lossis sib npaug ntawm 1.68V.
