Anodizing: aruminiyamu uye ayo alloys zvinoshandiswa sezvo anodes, uye kutungamirira kana graphite zvinoshandiswa sezvo cathodes. Mune imwe pfungwa (akadai sulfuric acid, oxalic acid, chromic acid, etc.) conductive mhinduro, kuburikidza rakaiswa voltage nokuitika Magetsi, mumwe ukobvu (8-12um) rukoko achiumbwa pasi pose akasimba, iro rine zvakanaka zvemaziso ehupfumi, zvakaoma, ngura nemishonga, vanopfeka nemishonga, kuputira, adsorbability uye zvichingodaro.
1. Degreasing: makemikari solvent degreasing, mvura inobva emulsification rokutsvaira mumiriri degreasing, electrochemical degreasing.
2. Chemical makorari: Uyezve dzichibvisa tsvina pamusoro pechiso aruminiyamu uye chiwanikwa waro phosphoric acid, uye kubvisa dzinongoitika oxide firimu pamusoro pemvura aruminiyamu chiwanikwa, saka kuti aruminiyamu substrate iri pachena kuti zviite tevera anodization. Panguva imwe cheteyo, pakuonekwa anewo nezvaizoitwa munoenzanisa, izvo zvinogona zvakare vamugadzirire pemvura workpiece pashure sandblasting, uye pose unaku iri nani.
3. peeling dema firimu: Mushure phosphorylation, firimu dema-pfumbu (simbi yakadai mhangura, nickel, manganese, simbi, nesilicon, nezvimwewo, izvo insoluble mune phosphoric acid) zvinosara pemvura workpiece, uye ipapo kubatwa nitric acid.
4. Oxidation: The muitiro pokubatana oxide firimu ane aruminiyamu chigadzirwa (anode) pasi zvinoitwa ane Zvakarurama kuitika pasi runoenzanirana electrolyte uye yakananga S ezvinhu. Anodic oxidation, kana kusingajekeswi, Rinowanzoreva Anodizing sulfuric acid.
5. kudhaya: kudhaya zvinofanira kuitwa pakarepo mushure anode uye kwete yakarebesa. Mushure oxidation, vachinyatsoongorora sukurudza kure residual asidhi nemvura inotonhora (kudzivisa tembiricha kumuka uye Kamudzira iri kwaita chisimbiso).
6. chisimbiso: yakakwirira tembiricha kufashaira mvura zvisimbiso pores, uye alumina rinobatanidza nemvura mamorekuru yokuumba hydrates, zvichiumba crystals.
7. Kuomesa: Nzvimbo chigadzirwa mu sechoto pamwe muchoto tembiricha wakaiswa pa 70 ° C. Kuiswa chisimbiso tembiricha haafaniri kukwirira, zvimwe firimu asingatani makatsemuka. Asati kugeza, inofanira kusukwa nemvura inopisa kuwedzera tembiricha pamusoro workpiece kuitira kuti anzvenge kutsemuka anokonzerwa workpiece kungokurumidza chando.
