1. Cov yam ntxwv tshwj xeeb: Kev ua haujlwm zoo tiv thaiv corrosion; ntev kev pab cuam lub neej ntawm electrodes; high tam sim no ceev thiab high tam sim no efficiency. Kev khiav hauj lwm tam sim no ceev: 10000A / M2 belongs rau oxygen evolution hom anode raws li kev lag luam ntshiab titanium.
2. Kev ua haujlwm siab catalytic: Platinum-plated electrode yog lub peev xwm peroxygen siab (1.563V txheeb ze rau mercurous sulfate) electrode, uas paub zoo. MMO anode yog qhov tsis tshua muaj oxygen evolution overcharge (1.385V txheeb ze rau mercurous sulfate) electrode, thiab cov pa oxygen evolution cheeb tsam ntawm anode yog yooj yim rau evolve oxygen. Yog li ntawd, lub cell voltage feem ntau tsis tshua muaj thaum lub sij hawm electrolysis, uas siv tsawg zog. Qhov tshwm sim no tau pom meej meej nyob rau hauv alkaline tooj liab-plated phab ntsa tom qab daim ntawv tooj liab.
3. Tsis muaj kuab paug. MMO Cov oxide no yog cov oxide ruaj khov thiab cov anodic txheej yog ceramic oxide ntawm cov hlau muaj nuj nqis iridium. Nws yuav luag insoluble nyob rau hauv tej acid los yog alkali, thiab oxide txheej yog li ntawm 20-40 μm. Tag nrho cov txheej txheej oxide cov ntsiab lus yog me me. Yog li ntawd, MMO anode yuav tsis ua phem rau cov tshuaj electroplating, uas yog qhov pib zoo ib yam li cov platinum-plated electrode.
4. Kev ua haujlwm siab: Tus nqi ntawm MMO anode yog kwv yees li 80 feem pua ntawm cov platinum-plated electrodes. MMO electrodes muaj kev ruaj ntseg electrochemical zoo dua hauv alkaline electroplating tooj liab electrolytes thiab tau tuav tib lub neej kev pab cuam xws li platinum-plated electrodes (txheej thickness 3.5mm). Nyob rau tib lub sijhawm nws muaj kev ua haujlwm zoo electrolytic thiab ua haujlwm ntev.)
5. Chlorides muaj nyob rau hauv qhov chaw galvanic nyob rau hauv sulfuric acid electrolyte. Siv lub dimensionally ruaj khov anode tiv thaiv qhov tshwm sim no thiab tso cai rau insoluble anode thev naus laus zis kom ua tiav kev ua tau zoo hauv daim ntawv thov no.
6. Anodes tsis tu ncua. Tsis tas yuav tsum tso tseg kev tsim khoom rau kev tu thiab rov ua dua anodes, hloov lub hnab anode, thiab rov txheej anodes (ua kom cov khoom tsim tau nce ntxiv thiab txo qis kev siv zog).
7. Lub neej ntawm insoluble anode nyob ntawm hom, kev ua haujlwm ceev tam sim no, thiab kev sib cuag nrog ntau yam tshuaj electroplating; vim tooj liab ions yog ib qho yooj yim mus mloog nyob rau ntawm ntug ntawm lub qhov (high tam sim no ceev cheeb tsam) thiab tsub zuj zuj sai, thaum lub hauv paus ntawm lub qhov (uas yog, tsis tshua muaj tam sim no cheeb tsam) cov tsub zuj zuj ceev kuj qeeb qeeb. Qhov no ua rau muaj kev sib faib tsis sib xws ntawm cov tooj liab: tus cwj pwm hu ua "dog pob txha". Kev khiav hauj lwm ntawm qhov nruab nrab tam sim no ua rau cov pob txha dev, ntawm qhov qis tam sim no qhov tshwm sim ntawm lub thoob tawg tshwm sim, thiab nyob rau hauv qhov siab dua tam sim no qhov tshwm sim tshwm sim. Qhov tshwm sim hlawv tshwm sim. Nws undoubtedly muaj kev cuam tshuam hnyav rau electroplated circuit boards. Kev siv platinum-titanium insoluble anodes nyob rau hauv sulfuric acid electrolytes ua rau thim rov qab mem tes plating anodes. Cov chlorides muaj nyob rau hauv ib puag ncig tam sim no thiab tom qab lub sijhawm yuav ua rau platinum txheej tev tawm.
