Aluminum magnesium manganese plate is a kind of roof and exterior wall material with high cost performance. Aluminum alloy has been widely used in the construction industry, and has played an important role in the development of modern architecture towards comfort, light weight, durability, economy and environmental protection. Aa3004 aluminum magnesium manganese alloy is widely recognized as a roof and exterior wall material with a service life of more than 50 years in architectural design due to its moderate structural strength, weather resistance, stain resistance, easy bending, welding and processing.
Coating of aluminum magnesium manganese alloy plate
Commonly used coatings are polyester (PE) paint coating and fluorocarbon (PVDF) paint coating.
PVDF coating: good wear resistance and excellent electrical performance; Excellent UV resistance; Good weather aging resistance, fire resistance, oil resistance and chemical corrosion resistance.
There are two types of PVDF coating systems:
1) Pre roll coated aluminum plate: the base material content of PVDF in the coating used for pre roll coating is as high as 70%, which is made by the horizontal automatic two coat two bake or three coat three bake roll coating process. Each coating needs to be baked and cured before coating; The compactness, corrosion resistance and aging resistance of the three coat and three bake coating are far better than those of the two coat and two bake coating.
2) Common sprayed aluminum plate: two coating and one baking or three coating and two baking coating is usually adopted, and the process is completed manually. The adhesion and surface color difference of the coating are inferior to those of the pre roll coated plate.
Main application
Due to the strong plasticity of aluminum magnesium manganese colored aluminum plate, it can be made into aluminum magnesium manganese sector plate, aluminum magnesium manganese arc plate, etc., which greatly meets the design requirements of metal roof for beauty and durability. Therefore, aluminum magnesium manganese metal roof system is widely used on the metal roof of large buildings such as steel structure workshop, gymnasium metal roof, airport metal roof, theater metal roof, high-end workshop metal roof, urban landmark buildings, civil buildings, etc.
