Faa'iidooyinka iyo khasaaraha ee saxan bir ah oo aluminium-zinc ah

Birta galvanized-ka kulul ayaa si weyn loogu isticmaalay dhismaha, qalabka guriga iyo warshadaha kale ee waaweyn tan iyo muuqaalkeeda.Sababtoo ah balaadhinta joogtada ah ee baaxadda isticmaalka, qaabeynta iyo sifooyinka kala duwan ee alaabooyinka ee saxanka birta ayaa si joogto ah loo wanaajiyaa, iyo natiijada aluminium-zinc ee saxanka birta ah ayaa ka sarreeya saxanka birta ah ee kuleylka leh ee guryaha qaarkood.Aluminium-zinc saxan bir ah oo dahaadhay
Saxan bir ah oo isku dhafan oo aluminium-zinc ah oo ka samaysan al-Zn waxaa lagu helaa dahaadh kulul oo leh saxan bir adag oo qabow-duuban oo xoog iyo dhumuc kala duwan leh sida walxaha saldhigga ah.Dahaarku wuxuu ka kooban yahay 55% aluminium, 43.5% zinc, 1.5% silicon iyo walxaha kale ee raadraaca.
Habka wax soo saarka iyo habaynta, waxqabadka aluminium-zinc plating ayaa ka sarreeya tan galvanizing-kulul, inta badan dhinacyada soo socda
Hagaajinta waxqabadka
Waxqabadka farsamaynta ee saxan bir ah oo aluminium-zinc ah ayaa la mid ah kan galvanizing-kulul, kaas oo si buuxda u buuxin kara shuruudaha habaynta ee duubista, shaabadda, foorarsiga iyo foomamka kale.
Iska caabbinta daxalka
Tijaabada waxaa lagu sameeyaa iyada oo la hoos dhisayo xaashida birta galvanized-kulul iyo aluminium-zinc bir ah oo dahaarka leh oo leh dhumuc isku mid ah, daahan iyo daaweynta dusha sare.Dahaarka aluminium-zinc wuxuu leeyahay iska caabin daxalka aad u fiican marka loo eego galvanizing kulul, iyo nolosheeda adeeggu waa 2-6 jeer saxan birta galvanized caadiga ah.
Waxqabadka iftiinka iftiinka
Awoodda zinc aluminiumka ah si ay u muujiso kulaylka iyo iftiinka ayaa laba jeer ka badan saxan birta galvanized ah, milicsiguna wuu ka weyn yahay 0.70, taas oo ka fiican 0.65 oo ay qeexday EPA Enerav Star
Iska caabbinta kulaylka
Alaabooyinka galvanized-ka ah ee caadiga ah waxaa lagu isticmaalaa heerkul aan ka badneyn 230 ℃, waxayna bedeli doonaan midabka 250 ℃, halka saxan aluminium-zinc ah loo isticmaali karo waqti dheer 315 ℃ iyada oo aan la bedelin midabka.Ka dib 120 saacadood oo ah 300 ℃, isbeddelka midabka ee aluminium-zinc saxan bir ah oo lagu daaweeyay kuleylka u adkaysta ee Baosteel ayaa aad uga hooseeya kan saxan aluminium ah iyo saxan aluminium ah
hantida farsamada
Qalabka farsamaysan ee aluminium-zinc ee saxan bir ah oo dahaadhay ayaa inta badan lagu muujiyaa xoogga dhalidda, xoogga xajinta iyo dhererka.Saxanka caadiga ah ee DC51D galvanized birta ah ee 150g/m2 waxa uu leeyahay xoog wax soo saar oo ah 140-300mpa, xoog xajin ah oo ah 200-330 iyo dhererka 13-25.Summada sumadda DC51D+AZ
Awoodda wax-soo-saarka ee xaashida birta ah ee aluminium-ku-salaysan ee leh 150g/m2 aluminium zinc waxay u dhaxaysaa 230-400mpa, xoogga adkaysigu waa inta u dhaxaysa 230-550, tareenka dhererkuna wuxuu u dhexeeyaa 15-45.
Sababtoo ah dahaarka aluminium-zinc waa birta aluminium-cufnaanta sare leh, waxay leedahay faa'iidooyin badan iyo cillado qaarkood
1. Waxqabadka alxanka
Sababtoo ah kororka guryaha farsamada, cufnaanta daahan ee dusha sare ee gudaha waa mid wanaagsan, iyo maadada manganese waa mid aad u sareysa, sidaas darteed zinc aluminium ah laguma alxan karo xaaladaha alxanka caadiga ah, waxaana lagu xiri karaa oo kaliya by rivets iyo dhinacyada kale.Marka la eego alxanka, saxanka birta ah ee galvanized-kuleylku si fiican ayuu u shaqeeyaa, mana jirto dhibaato alxanka.
2. Ku habboonaanta shubka heerkulka qoyan
Halabuurka aluminium-zinc ee daahan waxaa ku jira aluminium, kaas oo u nugul falcelinta kiimikaad ee xiriir toos ah la leh shubka qoyan ee acidic.Sidaa darteed, ma aha mid aad ugu habboon in la sameeyo looxyada sagxadda.
