Waa maxay faraqa u dhexeeya birta dahaarka leh ee Zinc-Aluminium-Magnesium iyo Aluminium-Zinc-Magnesium-ka Dahaarka leh?
Zinc-Aluminum-Magnesium (Zn-Al-Mg) birta dahaarka leh iyo Aluminium-Zinc-Magnesium (AZM) birta dahaarka ah waa laba nooc oo kala duwan oo ah xaashida dahaarka leh ee dahaarka leh. Kala duwanaanshahooda aasaasiga ah waxay ku jiraan saamiga aluminium (Al), zinc (Zn), iyo magnesium (Mg) ee ku dhex jira daahan, nidaamka substrate-ka hoose, iyo sifooyinkooda waxqabad ee gaarka ah iyo xaaladaha lagu dabaqi karo. Iyada oo ku saleysan heerarka warshadaha iyo ilaha awoodda leh, isbarbardhigga faahfaahsan ayaa lagu soo bandhigay hoos:
Qeexitaanno iyo Halabuurka Dahaarka
Birta Dahaarka leh ee Zinc-Aluminium-Magnesium (Zn-Al-Mg)
Daahan dahaarka ternary ah oo la sameeyay iyadoo lagu darayo aluminium iyo magnesium saldhig galvanized ah oo kulul.
Maadada magnesium waxay caadi ahaan u dhaxaysaa 0.2% ilaa 3%, halka aluminiumku ku kala duwan yahay nooca:
Nooca Aluminium-hoose: 1%-3.5%
Nooca aluminium-dhexe: 5%-11% (Doorashada guud ee codsiyada dhismaha)
Nooca Aluminium-sare: 55% (Asal ahaan wax ka beddelka saldhigga aluminium-zinc; ilaha qaar ayaa tan u kala sooca qaybta Zn-Al-Mg)
Aluminium-Zinc-Magnesium Dahaarka Birta (AZM)
Badeeco la hagaajiyay oo ku salaysan Aluminium-Zinc-Silicon (55% Al, 43.5% Zn, 1.5% Si) daahan, oo lagu daro qadarka raadraaca ee magnesium (caadi ahaan agagaarka 2%).
Halabuurka caadiga ah: 53% Al, 43% Zn, 2% Mg, 1.5% Si.
Waxaa loo tixgeliyaa nooca la cusboonaysiiyay ee daahan Aluminium-Zinc caadiga ah, halkii ay ka ahaan lahayd nidaam cusub oo daahan.
Mudnaanta sii Zinc-Aluminium-Magnesium Birta Dahaarka leh marka:
Iska caabin sare oo alkaline ah ayaa loo baahan yahay (tusaale, tas-hiilaadka xoolaha lagu dhaqdo ama meelaha kiimikada lagu sameeyo).
Awoodda Is-bogsiinta ee Jidhka-Jaray ayaa loo baahan yahay (hubinta ilaalinta daxalka xitaa ka dib marka la gooyo ama la feero).
Nolosha adeegga muddada-dheer waa mudnaanta (sida caadiga ah bixinta dammaanad 20-30 sano ah oo ka madax bannaan miridhku cas).
Tixgeli Birta Dahaarka leh ee Aluminium-Zinc-Magnesium marka:
Iska caabinta Daxalka Jawi Wanaagsan ayaa loo baahan yahay, oo ay weheliso Qurux ahaan "Spangle" (Zinc Crystal) Dusha sare (tusaale, daboolka dhismaha bannaanka).
Xasaasiyadda-kharashka waa arrin, iyo deegaanka ka hawlgala ma aha si adag alkaline.
