Sandblasting
Lub luag haujlwm tseem ceeb yog kev ntxuav saum npoo. Sandblasting (thaum pleev xim los yog tshuaj tsuag yas) ua ntej pleev xim tuaj yeem txhim kho qhov roughness.
Passivation
Passivation yog ib txoj hauv kev hloov cov hlau nto rau hauv qhov tsis muaj oxidizing, ncua tus nqi ntawm corrosion ntawm hlau.
Cov txheej txheem xim
Muaj ob txoj haujlwm tseem ceeb rau txhuas: ib qho yog aluminium oxide xim txheej txheem xim thiab lwm yam yog cov txheej txheem txhuas electrophoresis xim. Ntau yam xim yog tsim los ntawm oxide zaj duab xis kom ua tau raws li qee qhov kev xav tau, piv txwv li cov cuab yeej kho qhov muag feem ntau yog siv rau cov xim dub, cov tshooj ua koob tsheej yog xim daj, thiab lwm yam.
Tshuaj polishing kho tshuaj polishing yog txhuas thiab txhuas alloy nyob rau hauv cov kua qaub los yog txhuas alloy xaiv autolytic dissolution kom txo tau cov nto txhua xyoo kom txo tau nws nto roughness thiab pH tshuaj ua txoj kev. Txoj kev polishing no muaj qhov zoo ntawm cov cuab yeej siv yooj yim, tsis muaj zog, tsis muaj kev txwv loj sab nraud, tus nqi nkag siab, thiab cov nqi ua haujlwm tsawg. Lub purity ntawm txhuas thiab txhuas alloys muaj kev cuam tshuam zoo ntawm cov tshuaj polishing, qhov siab dua qhov purity, qhov zoo dua thiab zoo dua polishing zoo.
Tshuaj oxide zaj duab xis kho
Zaj duab xis, thickness ntawm txog 0.5-4 microns, ntxeem tau, mos, nrog zoo adsorption, yuav siv tau raws li ib tug substrate rau organic coatings, txhuas thiab txhuas alloy tshuaj oxidation txoj kev yuav muab faib ua alkaline oxidation thiab acid oxidation txoj kev raws li lawv cov kev daws teeb meem.
Qhov xwm ntawm zaj duab xis tuaj yeem muab faib ua oxide zaj duab xis, phosphate zaj duab xis, chromate zaj duab xis, thiab chromate-phosphate zaj duab xis.
Txau kev kho mob
Kev tiv thaiv sab nrauv, thiab kho kom zoo nkauj, feem ntau yog ua los ntawm oxidation. Cov khoom siv txhuas yuav tsum tau kho ua ntej ua ntej pleev xim txhawm rau ua kom cov txheej thiab cov khoom ua haujlwm ruaj khov, thiab muaj peb txoj hauv kev: phosphating (phosphate), chromatin (chromate-free chromatin), thiab tshuaj oxidation.
Electrochemical Oxidation Kev Kho Mob
Aluminium thiab aluminium alloy chemical oxidation kho cov cuab yeej yog qhov yooj yim, ua haujlwm tau zoo, ua haujlwm tau zoo, muaj ntau yam kev siv, thiab muaj qee qhov kev txwv. Lub thickness ntawm oxide zaj duab xis yog hais txog 5 mus rau 20 microns (nyuaj anodized zaj duab xis yuav ua tau 60 mus rau 200 microns tuab), nrog siab hardness, zoo tshav kub tsis kam, thiab rwb thaiv tsev, tsis kam mus rau tshuaj oxides, thiab ntxeem tau, thiab zoo heev adsorption muaj peev xwm.
