Ka dib markii dusha sare ee astaanta aluminiumka la anodized, filim ilaalin ah ayaa la samayn doonaa si loo xannibo hawada, si aluminium aluminiumku aanu u noqon mid oksaydh ah.Tani sidoo kale waa mid ka mid ah sababaha ay macaamiil badani u doortaan inay isticmaalaan aluminium profiles, sababtoo ah ma jirto baahi loo qabo in rinji iyo kharashka dayactirka waa yar yahay.Laakiin mararka qaarkood dusha sare ee aluminium profile waa madow.Waa maxay sababta tani?Aan ku siiyo hordhac faahfaahsan.
Waxaa jiri kara dhowr sababood oo madowga dusha aluminium aluminium, kuwaas oo qaarkood ay yihiin:
1. Oxidation: Aluminiyamku waxa ay soo bandhigtaa hawo waxayna la falgashaa ogsijiin si ay u samaysato lakab aluminium oxide ah oo korka ah.Lakabka oksaydhisku inta badan waa daah-furan wuxuuna aluminiumka ka ilaaliyaa daxal kale.Si kastaba ha ahaatee, haddii lakabka oksaydhku khalkhal galo ama dhaawacmo, waxay u soo bandhigtaa aluminiumka hoose ee hawada waxayna keeni kartaa oksaydh dheeraad ah, taasoo keenta muuqaal caajis ah ama madow.
2. Falcelinta kiimikaad: Soo-gaadhista kiimikooyinka ama walxaha qaarkood waxay sababi karaan midab-beddel ama madowga dusha aluminium alloy-ga.Tusaale ahaan, soo-gaadhista asiidhka, xalalka alkaline-ka, ama milixdu waxay sababi karaan fal-celin kiimikaad oo sababi karta madow.
3. Daawaynta kulaylka: Aluminium aluminiumka aluminiumka ah ayaa inta badan lagu sameeyaa hababka daaweynta kulaylka si ay u kordhiyaan xooggooda iyo adkaantooda.Si kastaba ha ahaatee, haddii heerkulka ama wakhtiga daaweynta kulaylka aan si habboon loo koontaroolin, waxay keeni doontaa midab ama madow oo dusha sare ah.
4. Wasakhowga: Joogitaanka wasakhaha dusha sare ee aluminium aluminium, sida saliidda, dufanka ama wasakhda kale, waxay keeni doontaa midab ama madow sababtoo ah falcelinta kiimikada ama isdhexgalka dusha sare.
5. Anodizing: Anodizing waa hab daawaynta dusha taas oo ku lug leh daawaynta korantada ee aluminium si ay u sameeyaan lakabka oksaydh ee dusha sare.Lakabka oksaydhisku waa la midabayn karaa ama la midabayn karaa si loo soo saaro dhammays kala duwan, oo uu ku jiro madow.Si kastaba ha noqotee, haddii habka anodizing-ka aan si habboon loo koontaroolin ama midabada ama midabada ay yihiin kuwo tayadoodu liidato, waxay keeni kartaa dhamaystir aan sinnayn ama midab.
