Bulk alumium panel is a kind of exterior wall decoration material, it is mainly made of aluminum alloy material, with light weight, high strength, corrosion resistance and other characteristics. Curtain wall aluminum veneer is beautiful and generous, rich in color, which can not only meet the appearance needs of modern buildings, but also add a unique artistic style to the building.
Bulk alumium panel has excellent quality and performance, is not easy to age, bright color, and has good corrosion resistance and ultraviolet resistance, can adapt to various extreme environments. In addition, the curtain wall aluminum veneer also has the characteristics of heat insulation, sound insulation, fire prevention, etc., making it one of the commonly used materials for modern architectural decoration.
Bulk alumium panel is widely used in commercial buildings, office buildings, hotels, public buildings and other building exterior wall decoration, green environmental protection, in line with the requirements of modern buildings. At the same time, curtain wall aluminum veneer has gradually spread to the field of home decoration, and the quality continues to improve, you can see that more and more families use curtain wall aluminum veneer as an exterior wall decoration material. These measures make the curtain wall aluminum veneer become an important part of China's construction industry, and bring beautiful appearance and good performance to the building.

bulk alluminum panel surface spraying process
bulk Aluminum panel spraying belongs to fluorocarbon spraying, the specific process is as follows:
Pre-treatment process:
Aluminum degreasing decontamination (pickling for about 10 minutes)→ water washing (through two channels of clean water)→ chromizing (about 5 minutes)→ water washing (through two channels of clean water)→100 degrees drying.
Spraying process:
hook (hanging aluminum on the assembly line)→ polishing decontamination → spraying primer → top paint → varnish → curing (baking for about 20 minutes at 180℃-250℃)→ quality inspection → unloading → packing film.

Bulk aluminum panel surface spraying process
1.The purpose of pretreatment:
Before spraying aluminum alloy profiles and plates, the surface of the workpiece should be degreased, decontaminated and chemically treated to generate chromizing film, increase the binding force and oxidation resistance of the coating and the metal surface, which is conducive to extending the service life of the paint film.
2.Hooks
Different shapes of aluminum are hung on the assembly line with corresponding hooks.
3. Primer spraying
As the primer coating of the closed substrate, its role is to improve the permeability resistance of the coating, enhance the protection of the substrate, stabilize the metal surface, strengthen the adhesion between the top paint and the metal surface, and ensure the color uniformity of the top paint.
4. Top paint:
Top paint coating is a key layer of spraying, which provides the decorative color required for aluminum, so that the appearance of aluminum meets the design requirements, and protects the metal surface from the external environment and prevents ultraviolet penetration. The anti-aging ability is greatly enhanced, and the top paint is the z-thick paint layer in the spray.
5. Varnish:
The main purpose is to effectively enhance the resistance to external corrosion of the paint layer, protect the top paint, increase the metallic luster of the top paint color, and make the appearance more gorgeous.
6. Curing treatment:
The aluminum sprayed three times enters the curing furnace for treatment, the curing temperature is generally between 180℃-250℃, and the curing time is about 20 minutes.
