Aluminized zinc coil yog cov khoom siv hlau nrog txheej txheej ntawm aluminium-zinc alloy coated rau saum npoo ntawm cov ntawv txias-rolled steel ntawv los ntawm kub-dip galvanizing txheej txheem. Nws muab cov kev tiv thaiv corrosion ntawm txhuas nrog kev tiv thaiv kev tiv thaiv ntawm zinc, thiab yog siv dav hauv kev tsim kho, cov khoom siv hauv tsev, thiab cov khoom siv hauv tsev.
Lub ntsiab nta thiab cov qauv
- Coating Composition: Typically composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, forming a dense quaternary crystalline structure at high temperatures, enhancing adhesion and protective performance.
- Dual Protection Mechanism: Aluminium ua ib qho kev tiv thaiv oxide insoluble, muab kev tiv thaiv lub cev; Zinc nyiam dua corrodes ntawm thaj chaw ntawm txheej puas, ua tiav kev tiv thaiv electrochemical (sacrificial anode).
- Kev Ua Tau Zoo: Muab piv rau cov ntawv galvanized steel, nws muaj kev tiv thaiv corrosion zoo tshaj, tiv thaiv tshav kub, thiab muaj kev cuam tshuam, nrog rau kev pab cuam lub neej ntawm ntau tshaj 20 xyoo.
- Cov txheej txheem ntau lawm: substrate tu thiab pretreatment kom tshem tawm cov roj thiab oxides; Kub-dip plating hauv aluminium-zinc alloy molten da dej ntawm kwv yees li 600℃; Passivation los yog oiling tom qab txias los txhim kho stability thiab processability; Rolling rau hauv coils thiab txiav kom loj raws li xav tau.
