Anodizing: aluminiyamu aluminium yayo asetyenziswa anodes, uziqhube okanye grafayithi zisetyenziswa cathodes. In a xi ethile (ezifana sulphuric acid, oxalic acid, chromic acid, njl) isisombululo conductive, ngenxa ombane isicelo kunye nefuthe umbane, eqinile (8-12um) umaleko luqokelelane phezu le nkampani, leyo eye iipropati elungileyo ngomatshini, lukhuni, nokumelana, anxibe ukuxhathisa, ukugcina ubushushu, adsorbability njalo njalo.
1. bamafutha: eziphilayo sijike bamafutha, amanzi esekelwe ukucoca emulsification bamafutha, bamafutha electrochemical.
2. Chemical ipolishi: Eminye ukususa ukungcola phezu kwamanzi aluminiyam kwaye ingxubevange yayo kunye phosphoric acid, kwaye ukhupha oxide umboniso zendalo phezu komhlaba ingxubevange aluminiyam, ukuze zeendawana aluminiyam bayaboniswa bachazelwe kangangoko lula anodization elandelayo. Kwangaxeshanye, lo wokucoca kwakhona kunesiphumo sokulinganisa, nto leyo ezigudileyo nangakumbi kumphezulu workpiece emva sandblasting, kwaye ukuguda noburhabaxa kumphezulu ingcono.
3. exwebula black umboniso: Emva phosphorylation, ifilim omnyama-esingwevu (metal ezifana nobhedu, nickel, manganese, intsimbi, lesilicon, njl, leyo ezingenakunyibilika in phosphoric acid) ihleli phezu komhlaba workpiece, yaye ke baphathwa nitric acid.
4. oksijini: Inkqubo zokubumba i umboniso oxide kwi imveliso aluminiyam (anode) phantsi kwe inyathelo umsinga isicelo phantsi electrolyte ehambelana neemeko ezithile s. Anodic igcwala, ukuba ingakhankanywanga, ngokuqhelekileyo kuthetha Anodizing sulphuric acid.
5. Ukudaya: Ukudaya kufuneka wenziwe ngokukhawuleza emva kokuba anode kwaye elide kakhulu. Emva igcwala, ngocoselelo pula ngaphandle lentsalela acid ngamanzi abandayo (aphephe lobushushu ukunyuka kunye inwebu ivaliwe ngokuzenzekela).
6. ukutywina: iqondo lobushushu eliphezulu amatywina amanzi abilayo pores, kunye alumina idibanisa kunye iimolekyuli zamanzi ukwenza carbohydrate, iikristali.
7. Ukuqwayita: Beka imveliso kwi-oveni kunye lobushushu oveni ebekwe kwi-70 ° C. Iqondo lobushushu uphawu akufuneki abe phezulu kakhulu, kungenjalo umboniso lithandwa ukuqhekeka. Phambi ukuhlamba, kufuneka ihlanjwe ngamanzi ashushu ukwandisa iqondo lobushushu workpiece ukuze ekuphepheni ukuqhekeza ezibangelwa ngokuba kubanda kakhulu le workpiece.
