Dab tsi yog hom ntawm cov titanium anodes?
1.Soluble anode thiab insoluble anode
Cov soluble anode ua lub luag haujlwm ntawm kev ntxiv cov hlau ions thiab coj hluav taws xob hauv cov txheej txheem electrolysis, thaum lub anode insoluble tsuas yog ua lub luag haujlwm ntawm kev ua hluav taws xob. Lub anodes insoluble ntxov tshaj plaws yog graphite thiab ua series koob anodes. Xyoo 1970, titanium anodes tau siv rau hauv kev kho electrolysis thiab electroplating kev lag luam ua lub thev naus laus zis tshiab. Tam sim no, insoluble anode tuaj yeem faib ua ob pawg: chlorine evolution anode thiab oxygen evolution anode. Chlorine evolution anode tsuas yog siv hauv chloride electrolyte system. Cov tshuaj chlorine tso tawm los ntawm anode thaum siv hluav taws xob, yog li nws yog hu ua chlorine evolution anode; oxygen evolution anode yog siv dav hauv sulfate, nitrate, hydrocyanate thiab lwm lub tshuab hluav taws xob, thiab oxygen tau tso tawm los ntawm anode thaum electroplating, yog li nws hu ua oxygen evolution anode. Lead alloy anode oxygen evolution anode, titanium anode raws li nws txheej catalytic txheej nto muaj cov haujlwm ua haujlwm ntawm oxygen oxygen, chlorine evolution lossis ob qho tib si.
2.Titanium anode rau chlor alkali kev lag luam
Piv nrog graphite electrode, qhov hluav taws xob ua haujlwm ntawm graphite anode hauv kev ua cov dej qab zib ntawm cov khoom siv diaphragm yog 8A / DM2, thiab cov anode coated tuaj yeem muaj txog 17a / DM2. Nyob rau hauv txoj kev no, nyob rau hauv ib puag ncig electrolysis zoo ib yam, cov khoom lag luam tuaj yeem muab ob npaug, thiab cov khoom zoo yog qhov siab thiab cov purity ntawm chlorine gas yog siab.
3.Titanium anode rau electroplating
Insoluble anode rau electroplating yog ib hom kev muaj npe zoo hlau oxide txheej nrog lub siab ntawm kev siv hluav taws xob zoo ntawm kev ua haujlwm ntawm titanium substrate (mesh, phaj, pluaj, tubular, thiab lwm yam), uas muaj cov siab ruaj khov valve hlau oxide. Cov hom tshiab ntawm insoluble titanium anode muaj lub siab electrochemical catalytic zog, oxygen evolution overpotential yog li 0.5 V qis dua ntawm cov hlau lead insoluble anode, nrog lub zog zoo kawg li txuag, siab ruaj khov, tsis muaj kuab paug ntawm plating daws, lub teeb ceeb thawj thiab hloov tau yooj yim. Cov pa oxygen overpotential ntawm tus tshiab insoluble titanium anode tseem qis dua li ntawm cov platinum plated insoluble anode, tab sis nws cov kev pabcuam lub neej tau nce ntau dua ib zaug. Nws yog dav siv raws li anode los yog ntu anode nyob rau hauv ntau yam electroplating. Nws tuaj yeem hloov cov pa txhuas ua raws li cov hlau nplaum anode. Raws li cov xwm txheej qub, nws tuaj yeem txo qis ntawm tes xovtooj ntawm tes thiab txuag hluav taws xob. Insoluble titanium anode muaj kev ruaj khov zoo (tshuaj lom neeg thiab hluav taws xob) thiab kev pab lub neej ntev. Cov anode no yog siv dav hauv npib tsib xee, kub, chromium, zinc, tooj liab plating thiab lwm yam kev lag luam hlau tsis muaj hlau
4.Pb-Titanium anodes
Pb-Titanium anodebelongs rau cov pa oxygen anode. Qhov electrolyte ntawm oxygen evolution tshwm sim yog sulfuric acid thiab sulfate, uas tsuas yog siv hauv electrolytic metallurgy. Qhov no anode muaj qhov tsis xws luag uas qhov loj me yuav hloov thaum lub sijhawm xaim hluav taws xob. Hauv cov txheej txheem electrolysis, cov hlau lead anode matrix yog thawj zaug hloov mus rau hauv cov hlau lead sulfate, thiab tom qab ntawd los ua oxide. Lead sulfate yog txheej nruab nrab, uas yog cov rwb thaiv tsev thiab ua cov txheej txheem tshuaj lom neeg. Nws tuaj yeem tiv thaiv cov xim txhuas sab hauv kev tsim hauv sulfuric acid ib puag ncig. Lead oxide hauv txheej txheej sab nraud yog cov tshuaj electrode. Cov pa oxygen tshwm sim ntawm nws. Cov pa oxygen muaj peev xwm ntawm cov hlau lead ntau heev, thiab nws nce nrawm nrog qhov nce ntawm qhov ntom ntom tam sim no. Cov yam ntxwv ntawm cov hlau lead anode yog txiav txim siab los ntawm qhov xam qhovkev ntawm nws cov khoom txheej sab nraud, cov hlau lead oxide, uas yog cov neeg coj tsis zoo ntawm hluav taws xob. Tsis tas li ntawd, nyob rau hauv cov txheej txheem ntawm electrolysis, qhov ua tau zoo ntawm lub tshuab hluav taws xob anode qauv ntawm cov hlau lead txo qis txuas ntxiv, thiab kev ntxhov siab sab hauv ua rau oxide txheej los ntawm txheej txheej poob tawm. Tsis tas li ntawd, kev tsim cov hlau lead peroxide kuj ua rau kev txhim kho tas mus li ntawm cov oxide. Raws li cov txheej nruab nrab, cov hmoov txhuas sulfate hloov pauv mus rau hauv txhuas oxide dua thiab dhau los ua cov khoom siv hluav taws xob tshiab ntawm cov hlau oxide sab nraud. Lub txhuas nyob rau hauv cov hlau lead yog oxidized dua Ib cov kev tiv thaiv kab ke tshiab ntawm cov hmoov lead sulfate tau tsim. Yog li ntawd, nyob rau hauv cov txheej txheem ntawm electrolysis, cov hlau lead thiab nws cov ntsiab lus sib txuas tsis tu ncua mus rau hauv lub tshuab hluav taws xob thiab cov nag lossis daus, uas ua rau muaj kev daws teeb meem paug thiab cathode cov pa phem.
