1. Xuab zeb blasting , lub ntsiab tseem ceeb yog ntxuav qhov chaw. Xuab zeb blasting ua ntej nrag (pleev xim los yog txau) tuaj yeem ua rau qhov chaw npoo thiab ua rau kev ua kom zoo dua, tab sis cov nyiaj pab tsawg, tsis zoo li ua ntej tshuaj lom neeg.
2. Piv txwv yog ib txoj kev hloov ntawm lub hlau tawm mus rau hauv lub xeev uas nws tsis yooj yim oxidized, thiab retarding tus corrosion tus nqi ntawm cov hlau.
3. Xim : Muaj ob txoj hau kev tseem ceeb rau cov xim txhuas xim: ib qho yog txhuas oxidation coloring, thiab lwm yam yog txhuas electrophoresis txheej txheem. Ntau cov xim yog tsim rau ntawm zaj duab xis oxide kom tau raws li qee qhov yuav tsum tau ua, xws li dub qhov chaw ntawm cov twj paj nruag kho qhov muag, kub sib tw, thiab kub kub. Ua cov pa oxidation (chromate conversion movie) - siv rau kev tiv thaiv thiab hluav taws xob.
4. Tshuaj Polishing yog ib hom tshuaj ua siv tshuaj uas siv cov txhuas thiab txhuas aluminium los txhuam tus kheej los ntawm cov kua qaub los yog alkaline electrolyte kom sib npaug ntawm cov nplai ntawm qhov chaw kom tsis txhob muaj cov kab npoo thiab pH. Txoj kev xaiv polishing muaj qhov zoo ntawm cov cuab yeej yooj yim, tsis muaj fais fab mov, tsis muaj kev txwv ntawm qhov loj ntawm lub workpiece, high speed ntawm ntuav thiab qes ua tus nqi. Lub purity ntawm txhuas thiab aluminium alloy muaj ib tug zoo cawv rau qhov zoo ntawm tshuaj polishing. Qhov siab dua qhov purity, qhov zoo dua qhov polishing zoo, thiab vice versa.
5, Cov tshuaj oxidation : oxidation oxidation , tuab ntawm li ntawm 0.5 ~ 4 microns, thiab ntxeem tau, mos, nrog adsorption zoo, yuav siv tau rau hauv qab txheej ntawm cov organic txheej, tab sis nws txoj kev hnav tsis zoo thiab kev sib txhuam tawm tsis zoo li anode Oxide zaj duab xis; cov txheej txheem tshuaj oxidation ntawm txhuas thiab txhuas txhuas tau muab faib ua ob pawg: alkaline oxidation hom thiab acid oxidation txoj hauv kev raws li cov khoom tov. Raws li qhov ntawm zaj duab xis txheej, nws muaj peev xwm yuav muab faib ua: oxide zaj duab xis, phosphate zaj duab xis, chromate zaj duab xis, chromic acid-phosphate movie.
6, Txau : rau sab nraud tiv thaiv, kho kom zoo nkauj ntawm cov khoom siv, feem ntau yog nyob ntawm oxidation. Aluminium yuav tsum tau ua ntej kho ua ntej txheej txheem kom cov txheej thiab cov workpiece khov kho. Nws muaj peb txoj kev: phosphating (phosphate method), chromium (chromium tsis pub chrome), thiab tshuaj oxidation.
7. Electrochemical oxidation , oxidation tshuaj oxidation tshuaj txhuas thiab txhuas txhuas yog yooj yim, yooj yim rau kev lag luam, ua haujlwm siab, tsis muaj hwj chim ntau, ntau daim ntawv thov, thiab tsis txwv los ntawm qhov loj thiab zoo. Lub thickness ntawm oxide zaj duab xis yog kwv yees li 5-20 microns (lub thickness ntawm cov zaj duab xis nyuaj anodized ncav 60-200 microns), cov hardness siab, kub kub thiab rwb thaiv tsev zoo, tus corrosion kuj siab dua tshaj ntawm cov tshuaj oxide zaj duab xis, thiab nws ntxeem tau. Zoo peev txheej adsorption.
