Kev txiav txim siab rau Iridium Mixed Hlau Oxide Coated Titanium Anodes

1. Iridium hlau oxide coated titanium anodes (hu ua iridium MMO coated titanium anodes) yuav tsum tau muab ntsia raws li kev pom zoo electrolysis.
2. Tsis txhob kis cov iridium MMO txheej nrog roj lossis roj.
3. Cov txheej iridium MMO yog cov txheej txheem ceramic nrog cov ntxeem tau nto thiab thaj chaw loj tshwj xeeb, uas muaj cov khoom siv hluav taws xob zoo. Iridium MMO yog ib qho yooj yim heev rau khawb los yog puas thaum cov khoom tawv rubs los yog khob ntawm nws qhov chaw: tsis txhob tso lub iridium MMO coated nto ncaj qha rau ntawm cov hlau nto, thiab npog cov tawv tawv nrog daim ntawv tiv thaiv los yog yas zaj duab xis; tsis txhob rub lossis swb lub iridium MMO txheej txheej ntawm ib qho tawv tawv; Yog hais tias muaj av los yog sediment rau ntawm iridium MMO txheej txheej, tsis txhob siv cov tshuab abrasive los ntxuav nws. Kev ntxuav ntawm lub anode nto los ntawm txoj kev xws li hlau txhuam, xuab zeb, xuab zeb lossis cov dav hlau dej siab yog txwv.
4. Thaum lub titanium anode raug tshem tawm ntawm lub tank electroplating, nws yuav tsum tau yaug nrog dej tam sim ntawd. Txhawm rau tiv thaiv acid corrosion, qhov no yog vim qhov concentration ntawm cov kua qaub nce raws li cov electrolyte dries tawm ntawm txheej txheej.
5. Titanium anodes uas yuav tsum tau khaws cia rau lub sij hawm ntev yuav tsum tau ua tib zoo ntim rau hauv, piv txwv li, air-filled yas ntim kom tsis txhob khawb ntawm iridium MMO-coated nto, los yog hmoov av.
6. Kev siv lub iridium MMO txheej rau qhov active feem ntawm titanium anode tso cai rau cov hluav taws xob tam sim no dhau los ntawm coated nto ntawm titanium anode rau hauv electrolyte, thaum lub uncoated titanium nto tseem inert. Yog tias muaj kev puas tsuaj rau thaj tsam me me ntawm iridium MMO txheej, titanium hauv qab txheej yog nyob rau hauv kev sib cuag ncaj qha nrog cov electrolyte, thiab titanium anode tseem tuaj yeem ua haujlwm li qub, vim tias nyob rau hauv cov xwm txheej anodizing, titanium nto tsim kev tiv thaiv. txheej thiab muaj kev sib txuas lus. oxide zaj duab xis mus tas li.
7. Yuav tsum muaj qhov nrug me ntsis ntawm cov electrodes. Kev sib tsoo luv luv ntawm titanium anode thiab plated feem tuaj yeem ua rau tsis muaj kev puas tsuaj rau iridium MMO txheej thiab tseem ua rau cov titanium substrate puas. Nyob rau hauv qhov kev tshwm sim ntawm ib tug loj luv luv Circuit Court, lub titanium anode yog kiag li puas.
8. Ntev npaum li lub titanium anode yog immersed nyob rau hauv los yog ncaj qha nyob rau hauv kev sib cuag nrog cov electrolyte, lub titanium anode yuav tsum nyob rau hauv lub xeev anodized. Yog hais tias lub titanium anode tsis energized, ib tug tsawg zoo voltage (residual voltage) yuav siv tau rau lub titanium anode. Qhov no yuav tsum tsuas yog 2 volts hla lub anode thiab cathode, tsis tas siv lub hwj chim mov thiab tam sim no loj. Iridium MMO-coated titanium anodes raug txwv tsis pub thim rov qab txhua lub sijhawm.
9. Cov kab tsis huv hauv cov electrolyte xws li txhuas, hlau thiab barium cov ntsiab lus yuav tsum tau tswj. Qhov no yuav tsis tsim ib tug loj npaum li cas ntawm anode deposits. Anode deposits tuaj yeem txhaws qhov chaw ntawm titanium anode thiab ua rau tsis sib xws ntawm cov anode tam sim no.
10. Organic additives yog ntxiv rau cov electrolyte, thiab cov additives sib txawv yuav muaj kev sib txawv rau lub neej ntawm titanium anode. Lub neej ntawm iridium MMO-coated titanium anodes tuaj yeem txo qis tshwj xeeb tshaj yog nyob rau hauv kev cuam tshuam ntawm additives lossis ntxiv oxides nrog cov khoom hluavtaws.
11. Deposit Deposit Tshem Tawm ntawm Iridium MMO Coated Titanium Anode Hydrochloric Acid - Cov kua qaub no zoo heev hauv kev tshem tawm txhua hom xeb zoo li cov deposits thiab calcium uas muaj deposits. Vim tias nws cov khoom txo qis, nws tsuas tuaj yeem ua haujlwm ntawm chav tsev kub thiab xav tau cov tshuaj dilute ntawm 37% hydrochloric acid tsis ntau dua 10% ntawm ntim. Vim tias titanium anodes tseem muaj peev xwm txo tau cov kua qaub xws li hydrochloric acid, lub sij hawm cov anode nyob rau hauv kev sib cuag nrog nws yuav tsum tau khaws cia kom tsawg, feem ntau 10 feeb. Txhawm rau txo qis qib ntawm hydrochloric acid nres, 0.1% ferric chloride tuaj yeem muab ntxiv rau cov tshuaj ntxuav ua ntej ntxuav. Lus Cim: Tom qab ntxuav nrog hydrochloric acid, titanium anode yuav tsum tau muab yaug kom huv si nrog dej, nyiam dua tag nrho submerged hauv dej li 10 feeb. Citric Acid --- Ntawm 40--50 degree , 5-10% citric acid hauv dej tuaj yeem siv los tshem tawm cov khoom uas muaj hlau. Tseem yaug lub anode ua tib zoo nrog dej tom qab ntxuav. Txawm li cas los xij, vim tias cov ntsiab lus siab nitric acid muaj zog oxidizing zog ntawm qhov kub thiab txias, ib txheej ntawm titanium oxide zaj duab xis yuav raug tsim nyob rau saum npoo ntawm titanium substrate. Cov conductivity ntawm cov yeeb yaj kiab no yog qhov tsis zoo, yog li nws yuav tsum tsis txhob muab tso rau hauv titanium anode nyob rau hauv concentrated thiab high-temperature nyob rau hauv nitric acid, tab sis tsis tshua muaj concentration thiab tsis tshua muaj kub ntawm nitric acid yog heev pab tau kom tshem tawm ntau yam precipitates uas muaj peev xwm tsim. soluble nitrate, xws li kev lag luam nitric acid diluted tsawg dua 10% thiab nyob rau hauv chav tsev kub.
