Thaum cov khoom hlau raug huab cua thiab dej vapor rau lub sijhawm ntev, lawv yooj yim raug rau oxidative corrosion, ua rau xeb ntawm cov hlau.
Yuav kom daws tau qhov teeb meem ntawm cov hlau corrosion, tib neeg tau tsim cov tshuaj tiv thaiv xeb.Nws cov ntsiab cai tiv thaiv xeb feem ntau suav nrog cov txheej txheem thaiv thiab cathodic tiv thaiv txoj cai.
Ua ntej tshaj plaws, ib qho ntawm cov txheej txheem tiv thaiv xeb ntawm cov xim pleev xim yog cov txheej txheem thaiv.Anti-xeb xim muaj cov tshuaj uas tuaj yeem tsim cov yeeb yaj kiab tiv thaiv.Cov yeeb yaj kiab tiv thaiv no tuaj yeem npog cov hlau nto, thaiv huab cua thiab dej vapor thiab tiv thaiv lawv los ntawm corroding cov hlau.Cov txheej txheem ntawm cov yeeb yaj kiab tiv thaiv no ua lub luag haujlwm hauv kev cais cov hlau los ntawm ib puag ncig sab nraud, yog li ncua kev pabcuam lub neej ntawm cov khoom hlau.
Lwm txoj hauv kev tiv thaiv xeb yog lub hauv paus ntsiab lus ntawm kev tiv thaiv cathodic.Antirust xim feem ntau muaj qee yam hlau ions.Cov hlau ions tuaj yeem tsim muaj kev tiv thaiv electrochemical barrier ntawm cov hlau nto, tig cov hlau mus rau hauv ib qho anode, yog li txo cov tshuaj tiv thaiv oxidation ntawm cov hlau nto thiab ua rau cov hlau ua kom qeeb.Cov xim tiv thaiv xeb tuaj yeem tsim kev tiv thaiv cathodic zoo li zinc, txhuas thiab lwm yam hlau, yog li ua tiav kev tiv thaiv xeb ntawm cov hlau.
Feem ntau, cov txheej txheem tiv thaiv xeb ntawm cov xim pleev xim feem ntau ncua sij hawm qhov tshwm sim ntawm cov hlau xeb los ntawm kev thaiv thiab cathodic tiv thaiv, thiab tiv thaiv qhov zoo thiab kev pab lub neej ntawm cov khoom hlau.Yog li ntawd, hauv kev siv engineering tiag tiag, nws yog ib qho tseem ceeb heev uas yuav tsum xaiv cov xim uas tsim nyog los tiv thaiv xeb, uas tuaj yeem ua rau lub neej ntawm cov khoom siv hlau thiab txo cov nqi tu.
