MMO titanium anode yog siv ntau dua hauv kev tiv thaiv cathodic. Nws muaj qhov zoo ntawm kev kub siab tam sim no, cov kua qaub tsis kam, lub neej ntev, thiab lwm yam. Cathodic tiv thaiv yog hais txog sab nraud cathodic polarization ntawm cov hlau tiv thaiv kom txo tau cov kev ua haujlwm thiab tiv thaiv cov hlau corrosion. Feem ntau, ob lub tswv yim tuaj yeem siv tau:
1. Txoj kev tiv thaiv cathodic tam sim no txaus siab
Txaus siab tam sim no cathodic tiv thaiv siv impressed tam sim no ua rau tag nrho saum npoo ntawm cov hlau tiv thaiv ib cathode. Thaum ua cov kev tiv thaiv cathodic tam sim no rau cov khoom siv hlau, txuas cov hlau nrog cov xaim mus rau qhov tsis zoo ntawm cov khoom siv hluav taws xob sab nraud, thiab txuas rau lwm qhov kev pabcuam anode rau cov ncej zoo ntawm cov khoom siv hluav taws xob. Nyob rau lub sijhawm no, tam sim no dhau los ntawm kev pabcuam anode, tom qab ntws los ntawm cov tshuaj electrolyte, feem ntau yog tsom rau kev tiv thaiv cathodic ntawm cov hlau, ua rau cov hlau cathodic polarization. Tam sim no ntws rov qab mus rau lub hwj chim mov los ntawm cathode, yog li txo tag nrho cov peev xwm ntawm cov hlau. Yog tias qhov siv tiv thaiv tam sim no loj txaus, qhov qub anode ntawm cov qauv tiv thaiv yuav tsis yaj lawm. Lub sijhawm no, tsuas yog cov tshuaj tiv thaiv cathodic yuav tshwm sim ntawm qhov chaw hlau, thiab cov khoom siv tam sim no ntxiv los ua kom tiav kev tiv thaiv. Thaum xaiv cov khoom siv cathode, peb yuav tsum tsim kho thiab txhim kho kev siv sib txawv.
MMO-coated titanium anode muaj qhov zoo conductivity thiab qhov chaw me me tso tawm tsis kam vim yog siv cov titanium hlau raws li cov substrate thiab platinum pawg hlau oxides nrog cov catalytic siab ua haujlwm raws li cov txheej txheem. Nws tsis yog eroded los ntawm nruab nrab thiab yog ib qho yooj yim rau txheej txheem. Nws tuaj yeem hloov mus rau qhov chaw sib txawv, xws li av, kav dej, thiab lwm yam xov xwm
2. Txoj kev tiv thaiv kev txi anode
Sacrificial anode kev tiv thaiv yog los txuas cov hlau uas muaj peev xwm tsis zoo rau cov hlau tiv thaiv zoo li cov anode, uas tsim cov roj teeb loj nrog cov hlau tiv thaiv hauv electrolyte. Tam sim no ntws los ntawm cov anode mus rau cov khoom siv hlau los ntawm electrolyte, thiab cathodic polarization ntawm cov khoom siv hlau raug tiv thaiv raws li.
