Daim ntawv thov

ntshiab iridium yog tshwj xeeb yog siv nyob rau hauv lub txim plug ntawm lub dav hlau, thiab yog tsuas yog saws los tsim scientific apparatus, thermo-coupling, kuj hlau, thiab lwm yam. Siv raws li alloy, iridium yuav txhim khu hardness thiab corrosion kuj ntawm lwm yam hlau. Ntshiab iridium feem ntau yog siv nyob rau hauv alloy, thiab yog tsis tshua siv ib leeg. Thaum iridium siv ib leeg, nws feem ntau yog nyob rau hauv daim ntawv ntawm ingot, crucible los yog hlau.

Nyob rau hauv acid nruab nrab oxygen evolving cov tshuaj tiv thaiv, muaj cov khoom siv hluav taws xob tsawg kawg nkaus, tab sis iridium-tantalum coated titanium anode yog cov khoom siv hluav taws xob zoo heev. Cov khoom no muaj feem xyuam rau electrolysis ntawm cov organic teeb meem xws li cysteine, glyoxylic acid, succinic acid, thiab lwm yam, Cr3+﹢→ Cr6+ electrolysis ntawm indirect oxidation, dej phwj pov tseg rau oxidize organic teeb meem thiab tshuaj lom cov khoom nyob rau hauv dej, xws li kev hloov dua siab tshiab ntawm CN-, nrog rau kev ua haujlwm ntawm cov khoom siv electrode hauv kev lag luam electro-plating, xws li Cr plated auxiliary anode, auxiliary anode ntawm electrolytic tooj liab, auxiliary anode ntawm electrolytic zinc, auxiliary electrode ntawm cathode tiv thaiv, thiab lwm yam. , cov khoom yuav siv tau nyob rau hauv electrolysis ntawm electrolytic cobalt thiab electrolytic nickel.

Iridium-tantalum coated titanium anode, nrog rau qhov zoo uas lwm cov anodes tsis muaj, yog suav hais tias yog lub tswv yim tshaj plaws thiab cov khoom siv zoo tshaj plaws anode nyob rau lub sijhawm tam sim no. Nyob rau hauv lub cathode tiv thaiv teb, titanium, uas yog coj los ua substrate, yog ib qho yooj yim mus ua ntau yam xav tau duab thiab yog lub teeb nyob rau hauv qhov hnyav, thiab muaj peev xwm ua rau nws yooj yim mus nqa thiab mount. Sab nraud titanium anode rau kev tiv thaiv cathode tam sim no nyob rau hauv daim ntawv strip-puab los yog tubular daim ntawv. Cov txheej txheem oxide nrog cov catalysis siab ua haujlwm them rau saum npoo ntawm cov electrode tuaj yeem tswj cov peev txheej ntawm titanium substrate uas tau nthuav tawm los ntawm qee qhov tsis xws luag hauv 2v, txhawm rau kom tsis txhob tawg lossis puas tsuaj ntawm cov yeeb yaj kiab ntawm titanium substrate (feem ntau, sab nraud voltage qis dua 60v thaum nws siv rau hauv av).

Iridium-tantalum oxide titanium anodemuaj kev ua tau zoo ntawm lub cev, tshuaj lom neeg thiab electro-chemical, thiab cov qauv khoom tuaj yeem txiav txim siab nyob ntawm tus neeg siv khoom xav tau.

Technical parameters: resistivity ntawm txheej yog {{0}} omegas.m; lub anode tsis tshua muaj resistant rau acid ib puag ncig, tsis tshua muaj polarity thiab sib piv tsis tshua muaj noj; lub anode yog yoog mus rau ntau qhov chaw xws li dej hiav txwv, dej tshiab thiab av los ntawm kev tswj cov khoom ntawm oxide txheej; kev pab cuam lub neej ntawm hybrid metallic oxide anode yog 20 xyoo nyob rau hauv kev ua hauj lwm tam sim no ceev ntawm 100A / m2 nyob rau hauv av txaj thiab kev noj ceev yog hais txog 0.1 mg / Aa; phenomenon ntawm passivating los yog dissolving yog zam txawm tias tam sim no ceev yog 5000A / square meter, yog li stabilizing kev ua tau zoo thiab txo nqi; nyob rau hauv kev tiv thaiv ntawm cov av saum npoo los yog tob hauv av ntim, kev pab cuam lub neej ntawm cathode tiv thaiv anode tsis tsawg tshaj li 20 xyoo nyob rau hauv tam sim no ceev ntawm 100A / m2; thiab kev pab cuam lub neej ntawm cathode tiv thaiv titanium anode tsis tsawg tshaj li 20 xyoo nyob rau hauv tam sim no ceev ntawm 600A / m2 nrog rau cov seawater nruab nrab.

Qhov sib ntxiv ntawm nws mus rau titanium anode nto tsim ib qho chaw ruaj khov thiab corrosion-resistant nto uas yog qhov zoo tagnrho rau ntau hom kev siv electrochemical, suav nrog electroplating, kev kho dej khib nyiab, thiab tsim cov tshuaj chlorine thiab caustic soda los ntawm cov txheej txheem chlor-alkali. .

Titanium Anode Txheej muaj ntau yam txiaj ntsig tshaj lwm yam khoom siv anode, suav nrog kev ua haujlwm siab rau corrosion, kev ua neej ntev, thiab kev saib xyuas tsawg. Lawv kuj tau txais txiaj ntsig zoo, vim tias kev siv iridium oxide tsawg tsawg piv rau lwm cov hlau muaj txiaj ntsig uas feem ntau siv hauv anodes, xws li platinum thiab palladium.

Zuag qhia tag nrho, iridium oxide txheej anodes yog ib qho kev txhim khu kev qha thiab muaj txiaj ntsig zoo rau ntau yam kev siv hluav taws xob hluav taws xob uas xav tau kev ua haujlwm siab thiab ua haujlwm rau corrosion.
