Kev txhim kho corrosion ntawm cov tso tsheb hlau luam hauv dej hiav txwv feem ntau yog electrochemical corrosion, uas yog, microcurrent yog generated thaum lub sij hawm corrosion. Los ntawm lub hauv paus ntsiab lus ntawm electrochemistry, nws tuaj yeem pom tias cathode ntawm lub xov tooj ntawm tes tsis corrode, tab sis tsuas yog cov anode corrodes. Yog li ntawd, tig cov hlau tiv thaiv mus rau hauv cathode tuaj yeem tiv thaiv corrosion ntawm cov hlau. Txoj kev no hu ua cathodic tiv thaiv.
Raws li kev cuam tshuam ntawm cov nqi roj thoob ntiaj teb, cov tuam txhab lag luam hauv xeev, cov lag luam ntiag tug, tshwj xeeb tshaj yog cov chaw nres nkoj hauv zos, tau nqis peev hauv kev tsim cov roj av tshwj xeeb. Kev ntsuas dej siab yog txheej txheem tseem ceeb hauv kev tsim kho lub tank loj. Raws li kev cuam tshuam ntawm thaj chaw thiab kev lag luam, feem ntau cov phiaj xwm roj cia siv dej hiav txwv rau kev ntsuas siab. Txhawm rau txo qhov corrosion ntawm cov hlau phaj los ntawm dej hiav txwv thaum lub sij hawm sim, kev tiv thaiv cathodic ib ntus yuav tsum tau muab ntsia rau ntawm qhov chaw ntawm lub tank cia. Txhawm rau txiav txim siab txog daim ntawv thiab ntau npaum li cas ntawm kev tiv thaiv cathodic, ua ke nrog GB50393-2008 thiab lwm yam kev qhia tshwj xeeb, noj 100, 000 cubic cia tank ua piv txwv, tus naj npawb ntawm cathodic tiv thaiv yuav tsum muaj rau 100 , 000 cubic cia tank yog xam, thiab nws yog siv rau hauv qhov project. Lub laj thawj ntawm kev suav yog txheeb xyuas los ntawm kev siv tswv yim.
Hauv Tianjin National Petroleum Reserve Base Project, dej hiav txwv tau siv rau kev ntsuas dej siab ntawm cov tso tsheb hlau luam. Raws li cov lus qhia saum toj no, aluminium-magnesium-indium-cadmium alloy anodes tau siv rau kev tiv thaiv cathodic. Tom qab kev ntsuas dej puv, nws tau pom tias qhov kev tiv thaiv zoo ntawm cov anode yog qhov zoo, uas txo qis corrosion ntawm seawater rau cov phaj hlau.
