What is sprayed aluminum plate?

Spraying aluminum plate is to spray various colors of fluorocarbon paint (or polyester paint) on the surface of aluminum plate, which is also called baking aluminum plate after high temperature baking and curing. Can be used for exterior wall and interior wall decoration, indoor ceiling, etc.

Sprayed aluminum alloy profiles have excellent corrosion resistance and weather resistance, durability, beautiful appearance decoration, simpler production process than anodic oxidation, environmental protection and other characteristics, and have been widely used in construction, decoration, transportation and other industries.

The key to ensure the quality of chromate conversion film and spraying is to chemically clean and corrode the aluminum alloy profile during pre-spraying, so as to remove the adhesions, natural oxide film and dust on the oil surface, expose the aluminum alloy matrix and form a uniform activated surface.

Generally, aluminum plates are sprayed with three layers of paint and baked twice: aluminum plates are sprayed with three layers of paint and baked twice. It means that three groups of spray guns are turned on during spraying, the first primer, the second color paint (fluorine paint or polyester paint) and the third protective topcoat (varnish). The second baking is to coat the aluminum plate with three layers and bake it twice. But now the spraying production line is basically: three layers, one drying, two coating and one drying.

Extended data:

Generally, the surface of aluminum veneer curtain wall is pretreated by chromium plating, and then sprayed with fluorocarbon. Polyvinylidene fluoride resin (KANAR500) is used in fluorocarbon coatings, topcoats and varnishes. Generally divided into two coating, three coating or four coating. Fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has excellent cold resistance and heat resistance, can resist strong ultraviolet radiation, can remain colorfast and non-powdering for a long time, and has long service life. applied range

The aluminum veneer curtain wall is suitable for the decoration of various buildings, such as internal and external walls, lobby facades, column decorations, elevated corridors, pedestrian overpasses, elevator packages, balcony packaging, advertising signs, indoor special-shaped ceilings, etc. Building exterior walls, beams and columns, balconies, canopy airports, railway stations, conference halls of hospitals, reception halls of opera houses and other high-rise buildings.
