makina apamwamba kwambiri a anodizing semi auto aluminium anodizing line
①Aluminium mbiri pamwamba chithandizo:
Chithandizo chapamwamba cha mbiri ya aluminiyamu, chomwe chimatchedwanso kuti pretreatment, ndikugwiritsa ntchito zinthu zakuthupi ndi mankhwala kuchotsa dothi pamwamba pa mbiri ya aluminiyamu, kuti mawonekedwe amtundu wa aluminiyumu awonekere, omwe ndi abwino kuti azitha kuchiritsa makutidwe ndi okosijeni pambuyo pake. mbiri pamwamba.
②Aluminiyamu pamwamba degreasing ndondomeko:
Cholinga cha ndondomeko degreasing kwa mbiri zotayidwa ndi kuchotsa mafakitale lubricating mafuta ndi odana dzimbiri mafuta padziko mbiri zotayidwa, komanso dothi ndi zonyansa kutsatira pamwamba mbiri, kuonetsetsa yunifolomu alkali dzimbiri mbiri zotayidwa, ndi kuonetsetsa ukhondo wa akasinja etching matanki;ndi kupititsa patsogolo chithandizo chapamwamba cha mbiri ya aluminiyamu.
③Aluminiyamu mbiri asidi etching ndondomeko:
Njira yopangira asidi pamwamba pa mbiri ya aluminiyamu ndikupangira mankhwala owononga asidi pambuyo pochotsa mbiri ya aluminiyamu.Cholinga chachikulu ndikuchotsa ma oxide omwe amapangidwa pambuyo pa makutidwe ndi okosijeni azinthu zina zachitsulo pamwamba pa mbiri ya aluminiyamu ndi mafilimu a oxide omwe amapangidwa mwachilengedwe ndi mbiri;ziyenera kuchitika mwamsanga pambuyo mankhwala dzimbiri asidi.Tsukani madzi, ndipo kutentha kwa kutsuka kwamadzi kumayendetsedwa kuyambira 50 ° C kuti mupewe zizindikiro zotuluka pamwamba pa mbiriyo, kenako kuyeretsa ndi madzi oyenda.Popeza mbiri ya aluminiyamu imakhala ndi zinthu zamkuwa, pamwamba pamakhala mdima pambuyo pa dzimbiri la asidi, ndipo iyenera kuviikidwa mu njira ya nitric acid kwa mphindi 3-5 kuti pamwamba pakhale siliva wowala.
④Njira ya alkaline etching ya mbiri ya aluminiyamu:
Cholinga chachikulu cha ndondomeko ya alkali etching ya mbiri ya aluminiyamu ndi yofanana ndi ndondomeko ya asidi etching, kuchotsa zinthu zotsalira ndi zigawo za metamorphic pamwamba pa mbiri ya aluminiyumu panthawi ya makutidwe ndi okosijeni, ndi kuthetsa zolakwika zowonongeka zomwe zatsala pa pamwamba pa aluminiyamu mbiri pa ndondomeko extrusion;Chithandizo chapamwamba cha alkali etching chimagwira ntchito yofunika kwambiri pazambiri zonse za aluminiyamu.
⑤Aluminiyamu kusalowerera ndale:
Cholinga cha ndondomeko zotayidwa mbiri neutralization ndi kuchotsa mkuwa, manganese, chitsulo, pakachitsulo ndi zinthu zina aloyi kapena zosafunika kuti kukhala pamwamba pa mbiri zotayidwa pambuyo etching asidi ndi alkali etching mankhwala, amene insoluble mu njira zamchere, ndi kusokoneza mbiri ya aluminiyamu.Sopo yotsala pambuyo popangira mankhwala a alkaline etching nthawi zambiri amagwiritsa ntchito 30% -50% nitric acid solution.Pamwamba pa silicon aluminiyamu aloyi, kuponyera mu aloyi, ntchito chisakanizo cha nitric acid ndi hydrogen fluoride voliyumu chiŵerengero cha 1:3 asidi.Silikoni imakumana ndi haidrojeni ndi hydrofluoric acid kupanga fluorosilicic acid ndikusiya pamwamba pa aluminiyamu.
⑥Anodizing mankhwala a aluminiyamu mbiri:
Njira anodizing mbiri zotayidwa ndi ntchito yankho monga sing'anga, ndi ntchito nsonga kumaliseche kupanga okusayidi filimu pamwamba pa mbiri zotayidwa, kotero kuti zotayidwa mbiri ali wapamwamba dzimbiri kukana, chifukwa cha wosanjikiza zoteteza analandira. ndi mbiri ya aluminiyamu ya anodized Ili ndi kuuma kwakukulu komanso kukana kwa dzimbiri, ndipo makulidwe ake ndi 10-12μ, omwe amatha kusintha kukana kwa makutidwe ndi okosijeni a mbiri ya aluminiyamu ndikuwongolera kukongola kwambiri.
Sulfuric acid anodization nthawi zambiri amagwiritsa 10-20% H2SO4 monga electrolyte, kutentha ntchito ndi 15-20 ℃, kachulukidwe panopa ndi 1-2.5A/dm2, ndi electrolysis nthawi zimadalira filimu makulidwe amafuna, zambiri 20-60min.Gwero lamphamvu kwambiri lamagetsi ndi Direct current.Mphamvu yamagetsi yomwe imagwiritsidwa ntchito imasiyanasiyana kutengera ma conductivity, kutentha ndi aluminiyumu zomwe zili mu electrolyte.Nthawi zambiri, ndi 15-20V.Magawo azinthu amakhudza kwambiri magwiridwe antchito a nembanemba.
⑦ Chithandizo chosindikizira mbiri ya Aluminium:
Pambuyo pa mbiri ya aluminiyamu ndi anodized, ma micropores adzapangidwa pamwamba, omwe ndi osavuta kukhala oxidized ndi corrod pa ntchito.Kusindikiza mankhwala ayenera kuchitidwa pambuyo anodizing mankhwala.Njira dzenje zimachokera ku Ulaya), sulfuric acid anodizing nthawi zambiri amagwiritsa ntchito 10-20% H2SO4 monga electrolyte, kutentha kwa ntchito ndi 15-20 ℃, kachulukidwe kameneka ndi 1-2.5A / dm2, nthawi ya electrolysis imadalira makulidwe a filimu. zofunikira, nthawi zambiri mu 20- 60min.Gwero lamphamvu kwambiri lamagetsi ndi Direct current.Mphamvu yamagetsi yomwe imagwiritsidwa ntchito imasiyanasiyana kutengera ma conductivity, kutentha ndi aluminiyumu zomwe zili mu electrolyte.Nthawi zambiri, ndi 15-20V.Magawo azinthu amakhudza kwambiri magwiridwe antchito a nembanemba.
