Taw qhia Ntawm Tantalum-iridium Coated Titanium Phaj Anode
Tantalum-iridium coated titanium phaj, qhov anode yog raws li titanium mesh, thiab β-PbO2 yog electroplated rau nws. Nws yog tsiag ntawv los ntawm cov pa super siab thiab tuaj yeem siv hauv kev daws teebmeem, tshwj xeeb hauv qee cov organic electrolysis. Qhov tshuaj tiv thaiv anodizing yuav tsum muaj peev xwm siab. Tab sis kom txo qis kev tshwm sim sab ntawm cov pa oxygen, PbO2 electrode yog cov khoom zoo dua. Xws li perchlorate electrolysis, dej phwj kho mob oxidizes organic teeb meem, xws li phenol-muaj dej phwj tuaj. Nws kuj tseem siv tau ua cov pa hluav taws xob uas siv hluav taws xob tsawg. Txawm hais tias nws cov pa yog super siab, nws tus nqi yog pheej yig dua li Ta-Ir electrode, yog li nws yog siv hauv cov organic electrolysis, electroplating, dej phwj thiab ntau lwm qhov chaw.
Tantalum-iridium coated titanium phaj yog ib hom oxygen evolution resistant anode, feem ntau yog siv rau cov kev hloov oxygen oxygen, tshwj xeeb tshaj yog haum rau cov kua roj ntsha, xws li qee qhov concentration ntawm sulfuric acid electrolyte, uas muaj ultra-low oxygen, yuav siv tau rau oxygen evolution electrolysis, thiab tseem tiv taus cov tshuaj chlorine xeb Nws tuaj yeem siv rau hluav taws xob uas tso pa oxygen thiab chlorine, xws li seawater electrolysis. Nws yog cov khoom siv hluav taws xob zoo rau cov xov xwm acidic kom tso oxygen, thiab muaj cov khoom siv hluav taws xob tsawg tsawg nyob rau hauv qhov chaw zoo li no. Cov kua hluav taws xob tau siv nyob rau hauv cov organic electrolysis, xws li cysteine, glyoxylic acid, succinic acid, thiab lwm yam Nws tuaj yeem siv rau oxidation ntawm Cr3+ → → Cr6+ electrolysis hauv organic electrolysis, thiab kev lim dej yog siv los oxidize organic thiab muaj tshuaj lom hauv dej. Xws li kev hloov pauv ntawm CN–. Nws kuj tseem siv tau los ua kev pabcuam electrode hauv kev lag luam electroplating, xws li ntu anode rau Cr plating, ntu anode rau electrolytic tooj liab, ntu anode rau electrolytic zinc, ntu anode rau kev tiv thaiv cathodic, thiab lwm yam.
Ruthenium-iridium-titanium ternary txheej anode
Cov anode coated yog siv hauv electrolytes nrog high hydroxide radicals, uas tiv taus cov pa corrosion thiab zoo rau ion-pauv membrane electrolysis. Txheej Performance Index:
1. Cov peev txheej paug tawm yog 1.18 volts (SCE) ntawm qhov ceev ntawm 4000A / m2 tam sim no.
2. txhim kho lub neej (txheej txheej txheej yuag yuag) 1.02mv / 4 teev. cm2, kev pabcuam lub neej yog lav rau ntau dua 5 xyoos, thiab nws tau siv rau hauv kev lag luam hauv cov tshuab hluav taws xob loj.
Ru-Ir-Sn-Ti (Ru-Ir-Sn-Ti) quaternary txheej electrode.
1. Cov chlorine evolution muaj peev xwm tsawg, thiab kev siv nyiaj ntau dhau me me. Cov chlorine muaj peev xwm tawm tsis ntau tshaj li 1.12V thiab qhov sib zog siv hluav taws xob tsawg dua 20mv ntawm qhov ceev ntawm 2000A / m2 tam sim no.
2.Qhov polarizability tsawg dua 30mv / 10 chav tsev tam sim no ntom ntom.
3. Lub neej ntev dua li ntawm 0.5N H2SO4, 1A / cm2 ntom ntom tam sim no, siv sijhawm ntev dua 1500 feeb.
Cov lus qhia saum toj no peb tau zoo dua li cov kev cai hauv kev lag luam (qhov ntsuas qhov kev lag luam yog: muaj peev xwm 1.13 volts, kev cai polarization 40mv / 10 chav ntsuas tam sim no, lub neej muaj zog ntau dua 1000 feeb). Cov xim pleev tau siv dav hauv kev lag luam chlor-alkali, thiab lub neej ua haujlwm tiag tiag tuaj yeem ncav cuag 8 xyoo.
