Lubroj thiab roj avkev lag luam yog ib feem tseem ceeb ntawm kev muab hluav taws xob thoob ntiaj teb, tab sis nws kuj yog ib qho ntawm cov lag luam uas muaj kev cuam tshuam loj tshaj plaws rau ib puag ncig. Txhawm rau kom txo qhov cuam tshuam rau ib puag ncig thiab xyuas kom meej tias kev siv cov peev txheej ruaj khov, kev lag luam tau siv ntau yam kev ntsuas, ib qho ntawm cov no yog kev siv cov thev naus laus zis tiv thaiv cathodic. Cov thev naus laus zis tiv thaiv cathodic siv dav hauv cov kav dej roj thiab roj, cov thoob dej cia khoom, cov chaw ua haujlwm hauv hiav txwv thiab lwm qhov chaw kom ntev lawv lub neej kev pabcuam thiab txo qhov kev pheej hmoo ntawm kev xau los ntawm kev xeb.
Kev tiv thaiv cathodic (CP) yog ib qho electro-Cov txheej txheem tiv thaiv tshuaj lom neeg siv los tiv thaiv kev xeb ntawm cov qauv hlau hauv ib puag ncig electrolyte. Cov thev naus laus zis no ua rau qeeb lossis nres cov txheej txheem xeb hauv cov chaw los ntawm kev siv hluav taws xob rau cov hlau. Muaj ob hom kev tiv thaiv cathodic tseem ceeb: kev tiv thaiv anode sacrificial thiab kev tiv thaiv cathodic tam sim no.
Kev tiv thaiv cathodic ntawm cov kav dej
Cov kav dej tsis muaj CP thov
CP siv rau cov kav dej
1. Kev tiv thaiv anode sacrificial:
Hauv txoj kev no, cov hlau uas muaj zog dua li cov hlau uas raug tiv thaiv (xws li magnesium, zinc lossis txhuas, thiab lwm yam) yog siv ua anode. Thaum lub anode txuas nrog cov hlau uas raug tiv thaiv thiab raug rau electrolyte (xws li av lossis dej), lub anode yuav xeb ntau dua, yog li tiv thaiv cov qauv hlau tseem ceeb.
Cov txiaj ntsig:
● Kev nqis peev thawj zaug thiab cov nqi khiav lag luam qis heev
● Kev tshuaj lom neeg tshwm sim sai, txo qhov nyuaj ntawm kev saib xyuas thiab cov nqi
● Tsis muaj cov khoom tsis zoo, tsis muaj kev cuam tshuam rau ib puag ncig
● Ncaj qha kho rau ntawm cov hlau tiv thaiv, yooj yim rau kev teeb tsa
Qhov Tsis Zoo:
● Yuav tsum tau kuaj xyuas thiab hloov pauv tas li, ua rau cov nqi kho mus sij hawm ntev nce ntxiv
● Tej zaum yuav tsis npog tag nrho cov qauv loj lossis nyuaj
● Cov khoom xeb yuav cuam tshuam rau cov khoom ntawm cov hlau
● Tej zaum yuav tsis ua haujlwm zoo hauv cov dej uas muaj zog tiv taus siab
2. Kev tiv thaiv cathodic tam sim no zoo kawg nkaus:
Kev tiv thaiv cathodic tam sim no yog ib qho thev naus laus zis siv ntau los tiv thaiv kev xeb hlau, tshwj xeeb tshaj yog nyob rau hauv cov teb ntawm kev tsim kho marine, petrochemicals, kev kho dej, thiab lwm yam. Txoj kev no suav nrog kev siv lub zog sab nraud los muab hluav taws xob los ntawm kev txuas cov qauv hlau rau qhov tsis zootus ncejntawm lub zog fais fab, txuasib qho anode pabcuam rau qhov zootus ncej, thiabcov dej ntws tam sim nolos ntawm anoderau qhov kev tiv thaiv.
Cov txiaj ntsig:
● Kev kho kom haum siabkev txawj ntse, tuaj yeem hloov kho rau ntau qhov chaw thiab cov ntaub ntawv sib txawv
● Tus nqi kho tsawg thiab lub neej ua haujlwm ntev
● Kev hloov pauv tau dav, tsim nyog rau ntau yam dej zoo thiab ib puag ncig
● Kev saib xyuas deb, yooj yim rau kev tswj hwm thiab kho
Qhov Tsis Zoo:
● Kev nqis peev loj thaum pib, xav taukev uacov khoom siv thiab thev naus laus zis tshaj lij
● Tej zaum yuav cuam tshuam rau cov qauv hlau nyob ze
● Yuav tsum tau kuaj xyuas tas li
● Kev ua haujlwm tsis raug yuav ua rau muaj kev cuam tshuam rau ib puag ncig
Hauv kev lag luam roj thiab roj av, kev tsim qauv, kev teeb tsa thiab kev saib xyuas cov kab ke tiv thaiv cathodic yog qhov tseem ceeb heev. Kev tiv thaiv cathodic kom zoo tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua, txo cov nqi txij nkawm, thiab ua kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
