Chiyambi chachidule

Anodized zotayidwa kapena zotayidwa aloyi mankhwala anayikidwa mu njira electrolyte kwa galvanization mankhwala, ndi ndondomeko kupanga zotayidwa okusayidi filimu padziko ndi electrolysis amatchedwa anodized mankhwala a zotayidwa ndi zotayidwa aloyi.Pambuyo pa anodic makutidwe ndi okosijeni mankhwala, zotayidwa pamwamba akhoza kutulutsa angapo microns - mazana a microns wa okusayidi film.Poyerekeza ndi zachilengedwe oxide filimu aloyi zotayidwa, kukana dzimbiri, kuvala kukana ndi kukongoletsa mwachionekere bwino ndi bwino.

Mfundo yoyenera

Mfundo ya anodic oxidation ya aluminiyamu ndiyo mfundo ya hydroelectrolysis. Mphamvu yamagetsi ikadutsa, zotsatirazi zimachitika:
Pa cathode, H2 imatulutsidwa motere: 2H + + 2e → H2
Pa anode, 4OH-4E → 2H2O + O2, mpweya wa mpweya si molecular oxygen (O2), komanso atomiki okosijeni (O) ndi ayoni okosijeni (O-2), nthawi zambiri amasonyezedwa ngati molekyulu mpweya mu anachita.
Monga anode, aluminiyamu imapangidwa ndi okosijeni ndi mpweya wa okosijeni pa iyo kuti ipange filimu ya Al2O3 popanda madzi: 2AI + 3[O] = AI2O3 + 1675.7kj Ziyenera kunenedwa kuti sizinthu zonse za oxygen zomwe zimagwirizanitsidwa ndi aluminiyamu, koma zina. amadziwikiratu ngati mpweya.
Anodic oxidation yakhala ikugwiritsidwa ntchito kwambiri m'makampani, mongaAluminiyamu CNC Machining zigawo.Pambuyo anodized, zotayidwa CNC Machining mbali akhoza kupeza zodabwitsa maonekedwe ndi wabwino antioxidant mphamvu.

Pali njira zambiri zotchulira mayina osiyanasiyana, zomwe zitha kufotokozedwa mwachidule motere:
Malinga ndi mtundu panopa, akhoza kugawidwa mwachindunji anodizing panopa, alternating anodizing panopa, ndi pulsed panopa anodizing, amene akhoza kufupikitsa nthawi kupanga kufika makulidwe chofunika, wosanjikiza filimu ndi wandiweyani ndi yunifolomu ndi wandiweyani, ndi kukana dzimbiri. ndi bwino kwambiri.
Malinga ndi electrolyte: asidi sulfuric, asidi oxalic, asidi chromic, asidi wothira ndi organic sulfonic asidi njira ya chilengedwe mitundu anodic makutidwe ndi okosijeni.
Malinga ndi mawonekedwe a filimuyo, imatha kugawidwa kukhala filimu wamba, filimu yolimba (filimu yokhuthala), filimu yaporcelain, wosanjikiza wowoneka bwino komanso chotchinga cha semiconductor.
Njira ya anodizing yachindunji ya electrosulfuric acid ndiyomwe imadziwika kwambiri, chifukwa ndi yoyenera kwa anodizing aluminium ndi ma alloys ambiri a aluminiyamu. Wosanjikiza wa filimuyo ndi wandiweyani, wolimba komanso wosavala, ndipo kukana kwa dzimbiri kungapezeke pambuyo posindikiza dzenje. filimu wosanjikiza ndi colorless ndi mandala, ndi mphamvu adsorption mphamvu ndi coloring mosavuta.Low processing voteji, zochepa mphamvu mowa; ndondomeko sifunika kusintha voteji mkombero, amene amathandiza kuti mosalekeza kupanga ndi ntchito zochita zokha; Sulfuric asidi ndi zochepa zoipa. kuposa chromic acid, kupezeka kwakukulu, ubwino wamtengo wotsika.
