Aluminium oxide tiag tiag yog aluminium oxide lossis aluminium alloy.Muaj ntau txoj hauv kev los oxidize aluminium, thiab lawv txhua tus siv tau.Aluminium oxidation muaj qee yam tshwj xeeb.Lub oxidized nto ntawm txhuas yuav muaj zog adsorption quab yuam thiab siab porosity, uas yuav ua rau cov txhuas yooj yim polluted tom qab oxidation.Yog li ntawd, tom qab anodic oxidation, lub oxide zaj duab xis yuav tsum tau muab kaw, thiaj li mus ntxiv txhim kho corrosion kuj thiab hnav tsis kam.Piv txwv li, boiling dej thiab chav sealing, hydrolytic ntsev sealing, dichromate sealing, sau thiab foob.Boiling dej thiab chav sealing txoj kev kuj yog cov feem ntau sealing txoj kev.
Cov txheej txheem boiling dej vapor sealing yog tshuaj oxidation cov tshuaj tiv thaiv, feem ntau yog tso cai rau alumina kom undergo anhydrous oxidation nyob rau hauv kub kub.Tom qab anhydrous oxidation, nws dhau los ua monohydrate, thiab qhov ntim ntawm oxide nce thiab oxidized rau hauv trihydrate.Thaum recombined, oxides nce hauv ntim ntau dua.Ntawm lawv, txoj kev sib khi ntawm cov dej kub npau npau yog muab cov oxidized aluminium rau hauv dej kub, thiab cov oxide zaj duab xis nyob rau sab hauv phab ntsa ntawm cov txheej thaiv txheej thiab cov txheej ntxeem tau yuav hydrated ua ntej, tab sis muaj qee qhov sib txawv ntawm ob, uas yuav ua rau hauv qab ntawm lub qhov yuav tsum tau muab kaw kom txog thaum nws kaw tag., lub voj voog dej yuav tsis mus, thiab cov dej kub npau npau oxidation pib los ntawm cov txheej membrane kom txog thaum qhov sib txawv tom qab raug thaiv.
Tau kawg, chav sealing yuav ua tau zoo dua ntawm kev sib khi qhov sib txawv dua li cov dej kub npau npau.Vim li no, qee qhov chaw tsim hluav taws xob aluminium oxidation tau pib siv peb lub tshuab hluav taws xob ua hluav taws xob, uas tuaj yeem zam qhov tsis sib xws los ntawm kev thaiv ntau npaum li qhov ua tau, tuaj yeem txhim kho kev ua haujlwm zoo ntawm lub Hoobkas, thiab txhim kho cov txheej txheem ntawm txhuas oxidation thiab kev txhim kho. ntawm qhov zoo ntawm cov khoom siv txhuas tau echoed hauv kev ua lag luam Zoo heev.
Vim li cas nws thiaj zoo dua los siv lub tshuab hluav taws xob rau txhuas oxidation?Qhov tseeb, thaum lub sij hawm txhuas oxidation txheej txheem, lub tshuab hluav taws xob tuaj yeem ncav cuag qhov kub thiab txias uas yuav tsum tau ua rau txhuas oxidation, thiab yuav tsis txo cov txhuas oxidation efficiency los yog ua rau lwm yam txawv txav vim muaj teeb meem.Lub tshuab hluav taws xob tuaj yeem ua kom sov cov dej kub, uas txhais tau hais tias tsis yog tsuas yog cov txheej txheem sib khi tuaj yeem pom tau, tab sis kuj tseem tuaj yeem ua tiav txoj kev sib khi ntawm cov dej kub npau npau.Rau cov nroj tsuag oxidation aluminium, muaj ntau txoj kev sib khi uas tuaj yeem xaiv los ntawm lawv tus kheej, uas tuaj yeem tsis tsuas yog txuag cov cuab yeej, tab sis kuj txhim kho kev ua haujlwm ntawm txhuas oxidation thiab txhim kho qib ntawm txhuas oxidation txheej txheem.
