Njira yopaka utoto ya anodic oxidation ya zigawo za aluminiyamu imayambitsidwa

1. Njira yopaka utoto wa monochrome: nthawi ya 4 koloko, zinthu za aluminiyamu zomwe zatsukidwa ndikutsukidwa ndi madzi zimamizidwa nthawi yomweyo munjira yopaka utoto. 40-60 ℃. Kumira nthawi: kuwala masekondi 30 mpaka 3 mphindi; Wakuda, wakuda kwa mphindi 3-10. Mukadaya, chotsani ndikusamba ndi madzi. 2, njira yopaka utoto wamitundu yambiri: ngati mitundu iwiri kapena kupitilira apo idayikidwa pa pepala limodzi la aluminiyamu, kapena kusindikiza malo, maluwa ndi mbalame, zolemba ndi zolemba, njirayi idzakhala yovuta kwambiri, kuphatikiza njira yopaka masking, kusindikiza mwachindunji ndi utoto. , njira yopangira thovu, etc. Njira zomwe zili pamwambazi zimagwira ntchito mosiyana, koma mfundo ndi yofanana. Tsopano, njira yophimba chophimba ikufotokozedwa motere: Njirayi makamaka imakhala ndi zokutira zoonda komanso zofananira za varnish yowuma mwachangu komanso yosavuta kuyeretsa pachikasu chofunikira kwambiri kuti chiphimbe. Pambuyo pouma filimu ya penti, sungani mbali zonse za aluminiyamu mu njira yothetsera chromic acid, chotsani mtundu wachikasu wa ziwalo zosaphimbidwa, muzimutsuka ndi madzi, zouma kutentha pang'ono, kenaka mupaka utoto wofiira. Ngati mukufuna kupaka utoto wachitatu ndi wachinayi, mutha kutsatira njirayi. 3. Kusindikiza: Pambuyo pa pepala lopangidwa ndi aluminiyamu latsukidwa ndi madzi, nthawi yomweyo amawiritsa m'madzi osungunuka pa 90-100 ℃ kwa mphindi 30. Pambuyo pa mankhwalawa, pamwamba pamakhala yunifolomu komanso yopanda porous, ndikupanga filimu yowonjezereka ya okusayidi. Utoto womwe umagwiritsidwa ntchito popaka utoto umayikidwa mufilimu ya oxide ndipo sungathenso kufufutidwa. Filimu yosindikizira ya oxide sikhalanso adsorbent, ndipo kukana kwake kuvala, kukana kutentha ndi kusungunula kumawonjezeka. Pambuyo posindikiza chithandizo, pamwamba pa zigawo za aluminiyumu zimauma ndi kupukutidwa ndi nsalu yofewa kuti mupeze chinthu chokongola komanso chowala cha aluminiyamu, monga utoto wamitundu yambiri. Pambuyo pa kusindikiza chithandizo, chotetezera chomwe chimagwiritsidwa ntchito pazigawo za aluminiyamu chiyenera kuchotsedwa, madera ang'onoang'ono ayenera kupukuta ndi acetone woviikidwa mu thonje, ndipo madera akuluakulu akhoza kuviikidwa mu acetone kuti asambe utoto. 1, mbali zotayidwa pambuyo kutsuka mafuta mankhwala, ayenera yomweyo oxidized, ndipo sayenera kuikidwa kwa nthawi yaitali. Zigawo za aluminiyamu zikapangidwa kukhala mafilimu a okusayidi, zonse ziyenera kumizidwa mu electrolyte, mphamvu ya batri iyenera kukhala yokhazikika komanso yosasinthasintha kuyambira koyambirira mpaka kumapeto, ndipo gulu lomwelo lazinthu liyenera kukhala losasinthasintha, ngakhale litapaka utoto. 2, panthawi ya anodizing, aluminiyumu, mkuwa, chitsulo, ndi zina zotero mu electrolyte zikupitiriza kuwonjezeka, zomwe zimakhudza kuwala kwa aluminiyumu. Pamene aluminiyumu ili yaikulu kuposa 24g/l, mkuwa umaposa 0.02g/l, ndipo chitsulo chimakhala choposa 2.5 o 'clock. 3, pogula zopangira ndi utoto, muyenera kusankha zinthu zoyera kwambiri, chifukwa zonyansa zonse zikangowonjezereka kapena kusakanizidwa ndi anhydrous sodium sulfate ndi dextrin, zopaka utoto sizili bwino. 4, pamene utoto wochuluka, njira yopaka utoto idzakhala yopepuka pambuyo pa ndende yoyamba, ndipo mtundu pambuyo popaka utoto udzawonetsa matani osiyanasiyana. Chifukwa chake, chidwi chiyenera kulipidwa pakusakaniza utoto wokhazikika pang'ono munthawi yake kuti musunge kusasinthika kwamtundu wa utoto momwe mungathere. 5. Popaka utoto wamitundu yosiyanasiyana, utoto wowala uyenera kudayidwa kaye, kenako mtundu wakuda uyenera kudayidwa ndi chikasu, chofiyira, chabuluu, chofiirira ndi chakuda. Musanayambe kudaya mtundu wachiwiri, utoto uyenera kukhala wouma kuti utoto ukhale pafupi ndi aluminiyamu pamwamba, apo ayi utoto udzalowetsedwa ndipo malire a burr sadzakhala omveka. 6, zonyansa za aluminiyamu zimakhudza utoto: zomwe zili ndi silicon ndizoposa 2.5%, filimu yapansi ndi imvi, iyenera kupakidwa utoto wakuda. Zomwe zili ndi magnesium ndizokulirapo kuposa 2%, ndipo gulu lothimbirira ndilopanda phokoso. Otsika mu manganese, koma osawala. Mtundu wa mkuwa ndi wofiyira, ndipo ngati uli ndi chitsulo chochuluka, faifi tambala, ndi chromium, mtunduwo umakhalanso wosawoneka bwino.
