Differential Aeration Corrosion tshwm sim thaum muaj qhov tsis sib xws ntawm cov pa oxygen rau thaj chaw ntawm tib cov hlau tivthaivNws yog hom electrochemical corrosion uas cuam tshuam rau cov hlau xws li hlau thiab hlau.. … Qhov no yog qhov uas cov oxidation tshwm sim, cov khoom siv corrosion thiab ib lub qhov ua rau cov hlau tsis muaj zog.
Dab tsi yog qhov txawv ntawm aeration corrosion piv txwv?
Corrosion vim ua ntej oxidation thiab txhuam. Qhov sib txawv aeration tshwm sim thaum ib feem ntawm ib daim hlau nyob twj ywm ntub ntev(thaum tsau rau ntawm phab ntsa lossis rau txoj kev pav, piv txwv li) thaum cov khoom seem qhuav. Tom qab ntawd qhov corrosion tshwm sim hauv thaj tsam nruab nrab ntawm ob sab (Daim duab 13.30).
Ntawm qhov twg ntawm cov hlau sib txawv aeration ntawm corrosion yuav tshwm sim?
Hauv qhov sib txawv aeration corrosion, cheeb tsam nrog cov pa oxygen ntau dua dhau los ua cov cathodethaj chaw uas muaj cov pa oxygen qis dua ua cov anode. Yog li ntawd, qhov seem ntawm cov hlau uas muaj cov pa oxygen tsawg dua yog qhov feem cuam tshuam rau corrosion.
Qib ntawm aeration cuam tshuam rau corrosion li cas?
Nyob rau hauv cov ntsiab lus, aeration accelerates anodic corrosion txheej txheem… Tsis tas li ntawd, qhov tseeb corrosion puas tuaj yeem ua phem dua vim tias muaj cov pa oxygen ntau ntxiv, kev txhim kho hauv cheeb tsam tuaj yeem nce tus nqi ntawm kev tawm tsam los ntawm Lwm qhov kev txiav txim ntawm qhov loj me uas tuaj yeem ua rau tag nrho 100 npaug ntawm qhov nkag mus.
Dab tsi yog qhov sib txawv aeration cell?
Ib qhov sib txawv aeration ntawm tes ua rau xeb ntawm cov hlau vim yog kev tsim cov pa oxygen concentration cell, uas yog tshwm sim los ntawm huab cua tsis sib xws ntawm cov hlau. … Ib lub xov tooj cua sib txawv tseem hu ua oxygen concentration cell.
