Kev taw qhia luv luv

Anodized aluminium lossis aluminium alloy cov khoom tau muab tso rau hauv cov tshuaj electrolyte rau kev kho galvanization, thiab cov txheej txheem ntawm kev tsim aluminium oxide zaj duab xis rau saum npoo los ntawm electrolysis yog hu ua anodized kho ntawm txhuas thiab txhuas alloy.Tom qab anodic oxidation kev kho mob, txhuas nto tuaj yeem tsim ntau microns - pua pua ntawm microns ntawm oxide zaj duab xis.Piv nrog lub ntuj oxide zaj duab xis ntawm aluminium alloy, nws cov corrosion kuj, hnav tsis kam thiab kho kom zoo nkauj yog pom tseeb thiab txhim kho.

Bacial txoj cai

Lub hauv paus ntsiab lus ntawm anodic oxidation ntawm txhuas yog qhov tseem ceeb ntawm hydroelectrolysis.Thaum ib qho hluav taws xob tam sim no dhau lawm, cov tshuaj tiv thaiv hauv qab no tshwm sim:
Ntawm cathode, H2 raug tso tawm raws li hauv qab no: 2H + + 2e → H2
Ntawm lub anode, 4OH-4E → 2H2O + O2, cov pa precipitated tsis yog molecular oxygen (O2), tab sis kuj atomic oxygen (O) thiab ionic oxygen (O-2), feem ntau qhia raws li molecular oxygen nyob rau hauv cov tshuaj tiv thaiv.
Raws li ib qho anode, aluminium yog oxidized los ntawm cov pa nag lossis daus ntawm nws los ua ib zaj duab xis Al2O3 yam tsis muaj dej: 2AI + 3 [O] = AI2O3 + 1675.7kj Nws yuav tsum tau taw qhia tias tsis yog tag nrho cov pa oxygen generated cuam tshuam nrog txhuas, tab sis qee qhov. ntawm nws yog precipitated nyob rau hauv daim ntawv ntawm cov roj.
Anodic oxidation tau ntev tau siv dav hauv kev lag luam, xws lialuminium CNC machining qhov chaw.Tom qab anodized, aluminium CNC machining qhov chaw tuaj yeem tau txais cov tsos zoo nkauj thiab muaj peev xwm antioxidant zoo.

Muaj ntau txoj hauv kev los sau cov npe sib txawv, uas tuaj yeem ua tiav raws li hauv qab no:
Raws li hom tam sim no, nws tuaj yeem muab faib ua tam sim no anodizing, alternating tam sim no anodizing, thiab pulsed tam sim no anodizing, uas tuaj yeem ua rau lub sij hawm luv luv kom ncav cuag qhov xav tau tuab, zaj duab xis txheej yog tuab thiab sib xws thiab ntom, thiab corrosion kuj. yog kho tau zoo heev.
Raws li cov electrolyte: sulfuric acid, oxalic acid, chromic acid, tov acid thiab organic sulfonic acid tov ntawm ntuj xim anodic oxidation.
Raws li cov khoom ntawm cov yeeb yaj kiab, nws tuaj yeem muab faib ua zaj duab xis zoo tib yam, zaj duab xis tawv (thick film), porcelain zaj duab xis, ci xim txheej txheej thiab txheej txheej txheej ntawm semiconductor kev txiav txim.
Txoj kev anodizing ncaj qha tam sim no electrosulfuric acid yog qhov nrov tshaj plaws, vim nws haum rau anodizing aluminium thiab feem ntau aluminium alloys.Cov zaj duab xis txheej yog tuab, tawv thiab hnav-resistant, thiab zoo corrosion kuj yuav tau tom qab sealing lub qhov. zaj duab xis txheej yog xim tsis muaj xim thiab pob tshab, muaj zog adsorption muaj peev xwm thiab xim yooj yim. Low processing voltage, tsawg zog noj; Cov txheej txheem tsis tas yuav hloov lub voj voog hluav taws xob, uas yog qhov tsim nyog rau kev tsim khoom tas mus li thiab kev ua haujlwm automation; sulfuric acid tsis tshua muaj teeb meem. tshaj chromic acid, khoom siv dav, tus nqi qis zoo.
