Nkoj Engineering

Thaum lub nkoj nyob hauv dej hiav txwv, nws cov qauv hlau tsim cov txheej txheem electrochemical corrosion nrog dej hiav txwv. Vim tias cov dej hiav txwv muaj cov ntsev ntau thiab lwm cov electrolytes, suav tsis txheeb cov galvanic hlwb yuav tsim nyob rau hauv cov hlau nto, ua rau cov hlau mus rau oxidation cov tshuaj tiv thaiv thiab corroded. Nkoj corrosion tuaj yeem ua rau txo qis ntawm lub zog ntawm lub nkoj, cuam tshuam rau kev nyab xeeb thiab kev pabcuam lub neej ntawm lub nkoj.

Hauv nkoj engineering, kev tiv thaiv cathodic yog ib qho tseem ceeb thev naus laus zis los tiv thaiv cov qauv hlau los ntawm kev corroded los ntawm seawater. Los ntawm inhibiting cov tshuaj tiv thaiv electrochemical corrosion ntawm cov hlau nto, nws txuas ntxiv lub neej kev pab cuam ntawm cov nkoj thiab ua kom muaj kev nyab xeeb kev nyab xeeb.

Cov txheej txheem kev tiv thaiv cathodic feem ntau hauv nkoj engineering suav nrog kev tiv thaiv kev tiv thaiv cathodic thiab txaus siab rau kev tiv thaiv cathodic tam sim no.

Sacrificial anode cathodic tiv thaiv

Sacrificial anode cathodic tiv thaiv Nws suav nrog kev txhim kho cov khoom siv hlau uas muaj peev xwm tsis zoo dua li cov hlau uas yuav tsum tau tiv thaiv (xws li zinc alloys, aluminium alloys, thiab lwm yam) raws li kev txi anode rau sab nrauv ntawm lub nkoj. Nyob rau hauv ib puag ncig dej hiav txwv, kev txi anodes corrode nyiam, muab kev tiv thaiv tam sim no rau cov khoom tiv thaiv thiab yog li tiv thaiv cov qauv hlau.

 

 

 

 

• Qhov zoo:Kev txhim kho yooj yim, tsis tas yuav muaj cov khoom siv hluav taws xob sab nraud, cov kev xav tau qis dua rau cov hluav taws xob rwb thaiv tsev ntawm cov nkoj, thiab kev ua haujlwm qis thiab cov nqi tu.
• Qhov tsis zoo: Lub neej kev pab cuam ntawm lub sacrificial anode yog txwv thiab nws yuav tsum tau hloov tsis tu ncua. Qhov loj thiab kev faib tawm ntawm kev tiv thaiv tam sim no yog qhov nyuaj rau kev tswj hwm qhov tseeb, thiab rau cov nkoj loj, yuav tsum muaj kev txi ntau dua anodes.

Rau txoj kev txi ntawm anode, cov khoom siv thiab cov khoom tshwj xeeb uas tsim nyog yuav tsum raug xaiv raws li qhov loj me, cov duab thiab cov kev taw qhia ib puag ncig ntawm lub nkoj, thiab lawv yuav tsum tau npaj kom tsim nyog nyob rau hauv cov cheeb tsam hauv qab dej ntawm lub nkoj, xws li hneev nti, stern thiab sab ntawm lub nkoj, uas yog feem ntau corrosion. Thaum txhim kho kev txi anodes, nws yog ib qho tsim nyog los xyuas kom meej tias qhov kev sib txuas ntawm lub anode thiab lub plhaub yog ruaj khov thiab txhim khu kev qha los tiv thaiv lub anode los ntawm kev poob thaum lub sij hawm navigation. Nyob rau tib lub sijhawm, xyuam xim rau qhov chaw teeb tsa thiab kev taw qhia ntawm lub anode kom ntseeg tau tias nws nyob hauv kev sib cuag nrog dej hiav txwv.

Peb kuj tsim cov khoom ua haujlwm rau cov nkoj, tshwj xeeb - zoo li cov anodes thiab cov ntaub ntawv siv.

Txaus siab rau kev tiv thaiv cathodic tam sim no

Txaus siab rau kev tiv thaiv cathodic tam sim no siv cov khoom siv hluav taws xob sab nraud los nruab rau lub anode ntawm qhov chaw tsim nyog ntawm lub nkoj, xws li lub stern lossis sab ntawm lub nkoj, nrog lub hull ua lub cathode. Cov zis tam sim no los ntawm cov khoom siv hluav taws xob ntws mus rau hauv cov dej hiav txwv los ntawm cov anode thiab tom qab ntawd mus txog qhov chaw ntawm lub nkoj, ua rau cathodic polarization ntawm lub hull thiab suppressing cov tshuaj tiv thaiv corrosion ntawm cov hlau.

• Qhov zoo: Qhov loj thiab kev faib tawm ntawm kev tiv thaiv tam sim no tuaj yeem raug kho raws li qhov tseeb ntawm lub nkoj, muab kev tiv thaiv zoo heev. Kev siv cov khoom siv anode kuj qeeb thiab nws lub neej kev pab cuam ntev.
• Qhov tsis zoo: Nws xav tau kev teeb tsa ntawm cov khoom siv hluav taws xob DC siab thiab tswj cov tshuab, ua rau cov nqi peev siab. Cov kev xav tau hluav taws xob rwb thaiv tsev rau cov nkoj yog qhov siab, thiab kev teeb tsa thiab kev saib xyuas yog qhov nyuaj.

Nkoj cathodic tiv thaiv yog cov cuab yeej tseem ceeb rau kev ua haujlwm ntev ntawm cov nkoj thiab txo cov nqi tu. Nws yog ib qho tsim nyog los xaiv ib qho kev daws teeb meem (saib anode lossis sab nraud tam sim no) raws li hom nkoj thiab qhov chaw corrosive, thiab tsim ib qho peb -dimensional anti-corrosion system los ntawm "cathodic tiv thaiv + txheej + ntse saib xyuas". Nrog rau kev txhim kho ntsuab thiab ntse thev naus laus zis, kev tiv thaiv cathodic rau cov nkoj yav tom ntej yuav ua tau zoo dua, lub zog-txuag thiab tus phooj ywg ib puag ncig, muab kev txhawb nqa rau kev tsim kho kom ruaj khov ntawm Marine engineering.
