Vim li cas MMO Titanium Ribbon Anode nrog Titanium Conductive Sawb Ua Mainstream rau Tank Hauv qab Cathodic Protection

Corrosion-induced leakage ntawm cov roj crude loj thiab cov tshuaj cia tank hauv qab yog ib qho kev pheej hmoo tseem ceeb ntawm kev nyab xeeb rau cov chaw khaws roj roj. Cov xuab zeb txaj hauv qab tso tsheb hlau luam nta cov av noo siab, cov ntsev cov ntsiab lus thiab hloov pauv av tiv taus. Kev sib cais anodes feem ntau ua rau muaj kev tiv thaiv tam sim no, tawm hauv ib feem ntawm lub tank-hauv qab qhov chaw tiv thaiv. Pitting leakage tuaj yeem tshwm sim tom qab ob peb xyoos ntawm kev pabcuam, ua rau kev khawb thiab kho cov nqi siab heev.

Nyob rau hauv niaj hnub ICCP impressed tam sim no cathodic tiv thaiv tej yaam num,faib mesh anode systems sib txuas MMO titanium ribbon anodes thiab titanium conductive stripstau dhau los ua cov kev daws teeb meem zoo tshaj plaws rau cov tshiab-tsim tank hauv qab cathodic tiv thaiv. Muaj ntau tus engineers sib xyaw ua ke ntawm lawv cov haujlwm. MMO titanium ribbon anode yog coated nrog iridium-tantalum sib xyaw hlau oxide, ua rau oxygen-evolution electrochemical cov tshuaj tiv thaiv thiab tso tawm tiv thaiv tam sim no. Lub titanium conductive strip tsis muaj cov txheej txheem catalytic, ua raws li cov khoom siv tam sim no kom xa tawm tam sim no los ntawm rectifier sib npaug rau txhua ntu ntawm MMO titanium ribbon anode. Hla-spot-welded pob qij txha tsim ua tiav mesh kom tshem tawm cov chaw dig muag tam sim no.

Substrates txais ASTM B265 Qib 1 ua lag luam ntshiab titanium nrog zoo ductility. Muab nyob rau hauv cov coils nruam, lawv tuaj yeem txiav ntawm qhov chaw. Tsis muaj coke backfill yuav tsum tau, thiab lawv tau muab tso ncaj qha rau ntawm lub tank-hauv qab xuab zeb txaj, yooj yim kev tsim kho piv nrog cov tsoos zoo sib sib zog nqus anode txaj. Qhov ntau thiab tsawg muaj xws li MMO titanium ribbon 6.35 × 0.635 mm, 12.7 × 0.9 mm. Titanium conductive strip cross-section yog xaiv raws li mesh dimension. Tus qauv coil ntev yog 152 m kom txo cov pob qij txha thiab cov kev pheej hmoo ua tsis tiav tom qab.

Ua pov thawj nyob rau hauv ntau qhov project hauv ntiaj teb no, qhov mesh anode system muab cov khoom faib tam sim no tshaj lub tank hauv qab, tsis txhob muaj kev tiv thaiv ntau dhau lossis kev tiv thaiv qis. Nws tsim kev pab cuam lub neej ncav cuag 25-50 xyoo, txuam lub tank tsim lub neej nrog yuav luag tsis muaj kev tu hauv av yuav tsum tau ua. Piv nrog graphite thiab high-silicon cam khwb cia hlau anodes, MMO titanium ribbon qhia tau hais tias tsis tshua muaj nqi noj. Tsis muaj kev xeb loj heev los ntawm cov khoom lag luam sib sau los thaiv cov kab nruab nrab, tiv thaiv qhov hluav taws xob tsis tu ncua thaum lub sijhawm ua haujlwm ntev.

 

 

Ib qho kev xaiv yuam kev yog siv MMO titanium ribbon anode ib leeg tsis muaj titanium conductive sawb rau kev sau tam sim no. Rau thaj tsam loj mesh layout, cia siab rau ntawm MMO ribbon cov conductivity ua rau qhov zoo tshaj plaws voltage poob tshaj qhov deb. Nyob deb anodes xa cov tam sim no tsis txaus thiab ua rau corrosion ntawm lub tank hauv qab ntug. Titanium conductive sawb ua haujlwm raws li cov pob txha pob txha kom ruaj khov tam sim no cov khoom siv thoob plaws tag nrho daim phiaj.

Qhov kev daws teeb meem no siv rau cov phiaj xwm tshiab-tsim thiab rov ua dua tshiab ntawm cov roj tso tsheb hlau luam, cov khoom siv roj tso tsheb hlau luam, cov tso tsheb hlau luam tshuaj thiab cov dej khib nyiab. Thaum muab khoom, txheeb xyuas qib titanium, MMO thermal-decomposition txheej txheej txheem thiab titanium qhov chaw-welding zoo kom muaj kev ruaj ntseg ntev kev ua haujlwm ntawm mesh anode systems.
