1. Anodizing
Anodizing ndi njira yochizira pamwamba pazitsulo zotayidwa zomwe zimagwiritsidwa ntchito popanga porous oxide wosanjikiza pamwamba pazitsulo.Njirayi imaphatikizapo anodizing (electrolytic oxidation) ya aluminiyamu mu njira ya asidi.Makulidwe a oxide wosanjikiza amatha kuwongoleredwa, ndipo chotsatiracho chimakhala cholimba kwambiri kuposa chitsulo choyambira.Njirayi ingagwiritsidwenso ntchito kuwonjezera mtundu kuzitsulo za aluminiyamu pogwiritsa ntchito mitundu yosiyanasiyana.Anodizing imathandizira kukana kwa dzimbiri, kukana kwambiri kuvala, komanso kukana kwa abrasion.Kuphatikiza apo, imatha kukulitsa kuuma komanso kumathandizira kumamatira kwa zokutira.
2. Kuphimba kwa Chromate
Chromate conversion coating ndi njira yochizira pamwamba pomwe zokutira zosinthira chromate zimayikidwa pamwamba pa aluminiyumu aloyi.Njirayi imaphatikizapo kumiza zigawo za aluminiyamu alloy mu njira ya chromic acid kapena dichromate, yomwe imapanga nsalu yopyapyala ya kutembenuka kwa chromate pamwamba pa chitsulo.Chosanjikizacho nthawi zambiri chimakhala chachikasu kapena chobiriwira, ndipo chimapereka chitetezo chokhazikika cha dzimbiri, kumamatira ku penti, komanso maziko abwino omatira ku zokutira zina.
3. Pickling (Kudula)
Pickling (etching) ndi njira yochizira pamwamba pa mankhwala yomwe imaphatikizapo kumiza ma aluminiyamu aloyi mu njira ya asidi kuti achotse zonyansa zapamtunda ndikupanga mawonekedwe owoneka bwino.Njirayi imaphatikizapo kugwiritsa ntchito njira yowonongeka kwambiri, monga hydrochloric kapena sulfuric acid, kuchotsa pamwamba pazitsulo.Izi zimatha kuchotsa zotsalira kapena zotsalira za oxide pamwamba pa aluminiyamu alloy pamwamba, kusintha mawonekedwe a pamwamba, ndikupereka gawo lapansi labwinoko lomatira.Komabe, sizimakulitsa kukana kwa dzimbiri, ndipo pamwamba pake imatha kukhala pachiwopsezo chambiri komanso kuwonongeka kwamitundu ina ngati sikutetezedwa mokwanira.
4. Plasma Electrolytic Oxidation (PEO)
Plasma Electrolytic Oxidation (PEO) ndiukadaulo wotsogola wapamtunda womwe umapereka wosanjikiza wokhuthala, wolimba, komanso wandiweyani pamwamba pa ma aluminiyamu.Njirayi imaphatikizapo kumiza zigawo za aluminiyumu alloy mu electrolyte, ndiyeno kugwiritsa ntchito magetsi kuzinthuzo, zomwe zimapangitsa kuti makutidwe ndi okosijeni achitike.Chosanjikiza cha oxide chomwe chimachokera kumapereka kukana kovala bwino, kukana dzimbiri, komanso kuuma kowonjezereka.
5. Kupaka ufa
Kupaka ufa ndi njira yotchuka yochizira pamwamba pazitsulo za aluminiyamu zomwe zimaphatikizapo kuwonjezera ufa woteteza pamwamba pazitsulo.Njirayi imaphatikizapo kupopera mankhwala osakaniza a pigment ndi binder pamwamba pa zitsulo, kupanga filimu yogwirizana yomwe imachiritsidwa pa kutentha kwakukulu.Chovala chaufa chotsatirachi chimapangitsa kuti chikhale cholimba, chosayamba kukanda, komanso chosawononga dzimbiri.Imapezeka mumitundu yosiyanasiyana, mawonekedwe, ndi zomaliza, zomwe zimapangitsa kuti ikhale yankho labwino pamapulogalamu ambiri.
Mapeto
Pomaliza, njira zochizira pamwamba zomwe tazitchula pamwambapa ndi zitsanzo zochepa chabe za njira zambiri zomwe zimagwiritsidwa ntchito popangira zida za aluminiyamu.Chilichonse mwamankhwalawa chimakhala ndi phindu lake lapadera, ndipo zosowa zanu zofunsira zimatsimikizira kuti ndi mankhwala ati omwe ali abwino kwambiri pantchito yanu.Komabe, mosasamala kanthu za njira yochiritsira yomwe imagwiritsidwa ntchito, chinthu chofunikira kwambiri ndikuwonetsetsa chidwi chokonzekera pamwamba ndikuyeretsa kuti mupeze zotsatira zabwino.Posankha njira yoyenera yochizira pamwamba, mutha kusintha mawonekedwe, kulimba, komanso magwiridwe antchito a zida zanu za aluminiyamu, zomwe zimapangitsa kuti mukhale ndi zinthu zapamwamba kwambiri zomwe zimatha nthawi yayitali.
