Intangiriro

Ibicuruzwa bya aluminiyumu cyangwa aluminiyumu bishyirwa mu gisubizo cya electrolyte yo kuvura galvanisation, kandi inzira yo gukora firime ya aluminium oxyde hejuru ya electrolysis yitwa anodised treatment of aluminium na aluminium.Nyuma yo kuvura okiside ya anodic, ubuso bwa aluminiyumu burashobora kubyara microne nyinshi - microni amagana ya firime ya okiside. Ugereranije na firime ya okiside isanzwe ya aluminiyumu, kurwanya ruswa, kurwanya imyenda no gushushanya biragaragara ko byateye imbere kandi bigatera imbere.

Ihame rya Bacial

Ihame rya okiside ya anodic ya aluminium ni ihame rya hydroelectrolysis.Iyo umuyagankuba wanyuze, reaction ikurikira iba:
Kuri cathode, H2 irekurwa gutya: 2H + + 2e → H2
Kuri anode, 4OH-4E → 2H2O + O2, umwuka wa ogisijeni waguye ntabwo ari ogisijeni ya molekile gusa (O2), ahubwo ni ogisijeni ya atome (O) na ogisijeni ionic (O-2), ubusanzwe igaragazwa nka ogisijeni ya molekile mu myitwarire.
Nka anode, aluminiyumu ihindurwamo umwuka wa ogisijeni kuri yo kugirango ikore firime ya Al2O3 idafite amazi: 2AI + 3 [O] = AI2O3 + 1675.7kj Twakagombye kwerekana ko ogisijeni zose zabyaye zikorana na aluminium, ariko zimwe yacyo igwa mu buryo bwa gaze.
Okiside ya Anodic imaze igihe kinini ikoreshwa cyane mu nganda, nkaaluminium CNC ibice byo gutunganya.Nyuma ya anodize, aluminium CNC ikora ibice birashobora kubona isura itangaje hamwe nubushobozi bwiza bwa antioxydeant.

Hariho inzira nyinshi zo kuranga amazina atandukanye, ashobora kuvunagurwa muburyo bukurikira:
Ukurikije ubwoko bwubu, irashobora kugabanywa muburyo butaziguye bwa anodizing, guhinduranya guhinduranya anodizing, hamwe na pulsed current anodizing, bishobora kugabanya igihe cyo gukora kugirango bigere kubyimbye bisabwa, igipande cya firime kibyimbye kandi kimeze kimwe kandi cyuzuye, hamwe no kurwanya ruswa. ni Byateye imbere.
Ukurikije electrolyte: aside sulfurike, aside oxyde, aside chromic, aside ivanze hamwe na acide sulfonique acide ya acide ya anodic oxydeire.
Ukurikije imiterere ya firime, irashobora kugabanywamo firime isanzwe, firime ikomeye (firime yuzuye), firime ya farashi, icyerekezo cyiza cyo guhindura hamwe na bariyeri yibikorwa bya semiconductor.
Uburyo bwa anodizing ya acide ya electrosulfurike itaziguye niyo ikunzwe cyane, kuko ikwiranye na anodize ya aluminium na aluminiyumu nyinshi. Igice cya firime kibyibushye, gikomeye kandi kidashobora kwangirika, kandi kirashobora kuboneka neza nyuma yo gufunga umwobo. firime ya firime ntigira ibara kandi ibonerana, hamwe nubushobozi bukomeye bwa adsorption hamwe nibara ryoroshye.Gabanya gutunganya voltage, gukoresha ingufu nke; inzira ntikeneye guhindura voltage cycle, ifasha kubyara umusaruro uhoraho no gukora ibikorwa bifatika; acide sulfurique ntabwo yangiza cyane kuruta acide chromic, itangwa ryinshi, ibyiza biri hasi.
