imashini nziza ya anodizing imashini igice auto aluminium anodizing umurongo

Umwanya wo kuvura hejuru ya aluminium:
Kuvura hejuru yumwirondoro wa aluminium, bizwi kandi nko kwitegura hejuru, ni ugukoresha ibintu byumubiri nubumara kugirango ukureho umwanda hejuru yumwirondoro wa aluminiyumu, kugirango umubiri wa aluminiyumu ugaragare, bikaba byoroshye kuvura okiside nyuma ya aluminium Umwirondoro.

②Aluminum umwirondoro wubutaka bugabanuka:
Intego yo gutesha agaciro imyirondoro ya aluminiyumu ni ugukuraho amavuta yo kwisiga mu nganda hamwe n’amavuta yo kurwanya ruswa hejuru y’imyirondoro ya aluminiyumu, hamwe n’umwanda n’umwanda ufatiye hejuru y’imyirondoro, kugira ngo alkali yangirika kuri profili ya aluminium, kandi kwemeza isuku y'ibigega bya alkali;no kunoza ubuziranenge bwo kuvura hejuru ya aluminium.

ProcessAluminum yerekana umwirondoro wa acide:
Uburyo bwa acide ya acide hejuru yumwirondoro wa aluminium nugukora imiti yo kwangiza aside aside nyuma yo gutesha agaciro imyirondoro ya aluminium.Intego nyamukuru nugukuraho oxyde yakozwe nyuma ya okiside yibindi byuma hejuru yumwirondoro wa aluminium na firime ya oxyde isanzwe ikorwa na profile;bigomba guhita nyuma yo kuvura aside.Kora amazi, kandi ubushyuhe bwo koza amazi bugenzurwa hakiri kare 50 ° C kugirango wirinde ibimenyetso bitemba hejuru yumwirondoro, hanyuma usukure namazi atemba.Kubera ko umwirondoro wa aluminiyumu urimo ibintu bikozwe mu muringa, ubuso bwijimye nyuma yo kwangirika kwa aside, kandi bugomba gushirwa mu gisubizo cya acide ya nitric mu minota 3-5 kugirango ubuso bwa feza bugaragare.

ProcessIbikorwa bya alkaline byo gutondeka imyirondoro ya aluminium:
Intego nyamukuru yuburyo bwa alkali bwo gutondekanya imyirondoro ya aluminiyumu irasa cyane nuburyo bwo gutema aside, kuvanaho ibintu bisigaye hamwe na metamorphic layer hejuru yumwirondoro wa aluminiyumu mugihe cya okiside, no gukuraho inenge zasigaye kuri hejuru yumwirondoro wa aluminium mugihe cyo gukuramo;Ubuso bwa alkali bwo kuvura bugira uruhare runini mubwiza rusange bwa aluminiyumu.

ProcessAluminum umwirondoro wo kutabogama:
Intego yibikorwa byo kutabogama kwa aluminiyumu ni ugukuraho umuringa, manganese, fer, silikoni nibindi bintu bivangavanze cyangwa umwanda uguma hejuru yumwirondoro wa aluminium nyuma yo guterwa aside no kuvura alkali, bidashonga mugisubizo cya alkaline, na gutesha agaciro umwirondoro wa aluminium.Lye isigaye nyuma yo kuvura alkaline ikoreshwa muri rusange ikoreshwa mugukoresha 30% -50% ya acide acide.Kuri aluminiyumu ya aluminiyumu ya silicon, ikajugunywa mu mavuta, ukoresheje uruvange rwa acide nitric na hydrogène fluoride mu kigero cya acide 1: 3.Silicon ifata hydrogène na aside hydrofluoric ikora aside ya fluorosilic hanyuma igasiga aluminiyumu.

⑥Gukoresha uburyo bwo kuvura imyirondoro ya aluminium:
Uburyo bwo kunanura umwirondoro wa aluminium nugukoresha igisubizo nkigikoresho, hanyuma ugakoresha inama isohoka kugirango ukore firime ya oxyde hejuru yumwirondoro wa aluminium, kugirango umwirondoro wa aluminiyumu ufite imbaraga zo kurwanya ruswa, bitewe nuburinzi bwabonye na anodize ya aluminiyumu Ifite ubukana bwinshi no kurwanya ruswa, kandi uburebure busanzwe ni 10-12μ, bushobora kurushaho kunoza okiside ya okiside ya aluminiyumu no kunoza ubwiza bwimyirondoro.
Acide ya sulfurike isanzwe ikoresha 10-20% H2SO4 nka electrolyte, ubushyuhe bwakazi ni 15-20 ℃, ubucucike buriho ni 1-2.5A / dm2, kandi igihe cya electrolysis giterwa nibisabwa na firime, muri rusange 20-60min.Imbaraga zisanzwe zikomokaho nubu.Umuvuduko ukoreshwa uratandukanye bitewe nubushobozi, ubushyuhe hamwe na aluminium ya electrolyte.Mubisanzwe, ni 15-20V.Ibipimo byimikorere bigira ingaruka zikomeye kumikorere ya membrane.

Umwirondoro wa kashe ya aluminium:
Umwirondoro wa aluminiyumu umaze gushyirwaho, micropores izakorwa hejuru, byoroshye guhinduka okiside no kubora mugihe cyo kuyikoresha.Kuvura kashe bigomba gukorwa nyuma yo kuvura anodize.Inzira yumwobo ikomoka mu Burayi), acide sulfurike anodizing isanzwe ikoresha 10-20% H2SO4 nka electrolyte, ubushyuhe bwakazi ni 15-20 ℃, ubucucike buriho ni 1-2.5A / dm2, igihe cya electrolysis giterwa nubunini bwa firime ibisabwa, muri rusange muri 20- 60min.Imbaraga zisanzwe zikomokaho nubu.Umuvuduko ukoreshwa uratandukanye bitewe nubushobozi, ubushyuhe hamwe na aluminium ya electrolyte.Mubisanzwe, ni 15-20V.Ibipimo byimikorere bigira ingaruka zikomeye kumikorere ya membrane.
