Bayan an yi watsi da saman bayanin martabar aluminium, za a samar da fim mai kariya don toshe iska, ta yadda bayanan aluminum ba zai zama oxidized ba.Wannan kuma shine daya daga cikin dalilan da yasa yawancin abokan ciniki suka zaɓi yin amfani da bayanan martaba na aluminum, saboda babu buƙatar fenti kuma farashin kulawa yana da ƙasa.Amma wani lokacin saman bayanin martabar aluminum yana yin baki.Menene dalilin hakan?Bari in ba ku cikakken gabatarwa.
Akwai dalilai da yawa da ke haifar da baƙar fata daga saman alloy na aluminum, wasu daga cikinsu sune:
1. Oxidation: Aluminum yana nunawa zuwa iska kuma yana amsawa tare da oxygen don samar da Layer na aluminum oxide a saman.Wannan Layer oxide yawanci a bayyane yake kuma yana kare aluminum daga ƙarin lalata.Duk da haka, idan Layer oxide ya damu ko ya lalace, yana nuna alamar aluminum zuwa iska kuma zai iya haifar da ƙarin oxidation, wanda ya haifar da bayyanar duhu ko baƙar fata.
2. Chemical dauki: Bayyana wasu sinadarai ko abubuwa na iya haifar da canza launi ko baƙar fata na alloy na aluminum.Misali, fallasa ga acid, maganin alkaline, ko gishiri na iya haifar da halayen sinadarai wanda zai iya haifar da duhu.
3. Maganin zafi: Aluminum alloys sau da yawa ana fuskantar hanyoyin maganin zafi don ƙara ƙarfin su da taurin.Koyaya, idan yanayin zafi ko lokacin maganin zafi ba a sarrafa shi yadda yakamata, zai haifar da canza launin ko baƙar fata.
4. Gurbacewa: Kasancewar gurɓataccen gurɓataccen abu a saman na'urorin aluminium, kamar mai, maiko ko sauran ƙazanta, zai haifar da canza launi ko baƙar fata saboda halayen sinadarai ko hulɗar saman.
5. Anodizing: Anodizing ne a saman jiyya tsari da ya shafi electrochemical jiyya na aluminum don samar da Layer na Oxide a saman.Ana iya yin rini ko tinted wannan Layer oxide don samar da nau'ikan ƙarewa, gami da baki.Duk da haka, idan tsarin anodizing ba a sarrafa shi yadda ya kamata ko rini ko masu launi ba su da kyau, zai iya haifar da rashin daidaituwa ko canza launi.
