Feem ntau, qhov kub lossis siab nce ncaj qha ua rau tus nqi corrosion ntau dua vim tias cov tshuaj electrochemical feem ntau tshwm sim sai dua ntawm qhov kub siab dua. Kub nce ntxiv zog rau cov tshuaj tiv thaiv, uas ua rau nce tus nqi corrosion.
Dab tsi yog qhov cuam tshuam ntawm qhov kub thiab txias ntawm corrosion?
Nws pom tau tias qhov kub thiab txias tsis tsuas yog txo qis cov pa oxygen solubility thiab nce cov pa diffusivity hauv cov kua zaj duab xis , tab sis kuj txhawb nqa cov ions (xws li Cl -) thiab nrawm tsim cov khoom Al corrosion.
Vim li cas ho tsis cov khoom uas xeb kub?
Ntau cov khoom xeb hauv lub neej niaj hnub, xws li tsheb, shovels, thiab lwm yam, muaj thaj chaw me me uas xeb thiab yog li yuav tsis xeb ze li sai thiab yog li yuav tsis tsim kom muaj cua sov pom hauv koj qhov kev sim.
Dab tsi yog qhov cuam tshuam ntawm qhov ntsuas kub ntawm tus nqi ntub dej?
Peb paub tias, ntawm nce kub ceev ntawm ions koom nrog hauv cov tshuaj tiv thaiv nce. Yog li, lawv feem ntau nrawm nrog qhov kub thiab txias.=> Corrosion ua sai dua nyob rau hauv ib puag ncig sov dua li qhov txias dua.. Tab sis, lub luag haujlwm tseem ceeb hauv corrosion yog ua los ntawm Oxygen.
Yuav ua li cas thiaj nce tus nqi xeb?
Xeb yog tshuaj tiv thaiv uaskoom nrog kev sib pauv ntawm electrons ntawm atoms; Qee cov tshuaj tuaj yeem ua kom xeb los ntawm nce cov hluav taws xob ua haujlwm ntawm hlau thiab oxygen. Cov khoom xws li cov ntsev thiab cov kua qaub ua kom cov dej noo nyob ib puag ncig cov hlau, ua rau xeb tshwm sim sai dua.
