Kupaka mafuta: aluminiyamu ndi zitsulo zake zimagwiritsidwa ntchito ngati ma anode, ndipo lead kapena graphite zimagwiritsidwa ntchito ngati ma cathode. Mu kuchuluka kwina (monga sulfuric acid, oxalic acid, chromic acid, ndi zina zotero) yankho loyendetsa magetsi, kudzera mu mphamvu yamagetsi yogwiritsidwa ntchito komanso mphamvu yamagetsi, makulidwe ena (8-12um) amapangidwa pamwamba pa kampani, yomwe ili ndi mphamvu zabwino zamakanika, kuuma, kukana dzimbiri, kukana kukalamba, kutchinjiriza, kukana kukhuthala ndi zina zotero.
1. Kuchotsa mafuta: kuchotsa mafuta osungunuka achilengedwe, kuchotsa mafuta pogwiritsa ntchito madzi pogwiritsa ntchito emulsification, kuchotsa mafuta pogwiritsa ntchito electrochemical.
2. Kupukuta mankhwala: Kuchotsa dothi pamwamba pa aluminiyamu ndi aloyi yake ndi phosphoric acid, ndikuchotsa filimu yachilengedwe ya oxide pamwamba pa aloyi ya aluminiyamu, kuti gawo la aluminiyamu liwonekere kuti lithandizire anodization yotsatira. Nthawi yomweyo, kupukuta kumakhalanso ndi mphamvu yolinganiza, yomwe imatha kusalala pamwamba pa workpiece pambuyo popukuta mchenga, ndipo mawonekedwe a pamwamba amakhala abwino.
3. Filimu yakuda yochotsa: Pambuyo pa phosphorylation, filimu yakuda-imvi (chitsulo monga mkuwa, nickel, manganese, chitsulo, silicon, ndi zina zotero, zomwe sizisungunuka mu phosphoric acid) zimakhalabe pamwamba pa workpiece, kenako zimatsukidwa ndi nitric acid.
4. Kusungunuka kwa Oxidation: Njira yopangira filimu ya oxide pa chinthu cha aluminiyamu (anode) pansi pa mphamvu yamagetsi yomwe imagwiritsidwa ntchito pansi pa electrolyte yofanana ndi mikhalidwe yeniyeni ya s. Kusungunuka kwa anodic, ngati sikunatchulidwe, nthawi zambiri kumatanthauza Anodizing sulfuric acid.
5. Kupaka utoto: Kupaka utoto kuyenera kuchitika nthawi yomweyo pambuyo pa anode ndipo osati nthawi yayitali. Mukapaka utoto, tsukani mosamala asidi wotsalayo ndi madzi ozizira (pewani kukwera kwa kutentha ndipo nembanembayo imatsekedwa yokha).
6. Kutseka: madzi otentha kwambiri amatseka ma pores, ndipo alumina imasakanikirana ndi mamolekyu amadzi kuti apange ma hydrate, ndikupanga makhiristo.
7. Kuumitsa: Ikani chinthucho mu uvuni pomwe kutentha kwa uvuni kuli pa 70 °C. Kutentha kotseka sikuyenera kukhala kokwera kwambiri, apo ayi filimuyo imatha kusweka. Musanatsuke, iyenera kutsukidwa ndi madzi otentha kuti kutentha kwa chinthucho kuwonjezere kuti chisasweke chifukwa cha kuzizira kwambiri.
