Aluminum curtain walls used in construction include single-layer aluminum panels, aluminum-plastic composite panels, aluminum honeycomb panels and other materials. Building decoration works. Aluminum curtain wall is also a form of curtain wall. Simply put, aluminum curtain wall is used instead of glass to make curtain wall. Aluminum curtain wall is mostly used for wall shielding and non-lighting walls. For example, the Guangzhou World Trade Center used nearly 150 tons of aluminum plates with different curvatures, and the surface was electrostatically sprayed. Foreign aluminum curtain walls have been using single-layer aluminum panels. Single-layer aluminum panels generally use pure aluminum panels.

 Ø Casting rolling process of aluminum plate production

Aluminum ingots or waste aluminum are melted and cast, and after degassing, the melt enters the casting rolling mill and the cold rolling mill to be rolled into aluminum plates.

Aluminum casting rolling is a new process that directly "casts and rolls" aluminum or aluminum alloy melts into semi-finished billets or finished products. The remarkable feature of this process is that its crystallizer is two rotary casting rolls with water cooling system, and the melt completes two processes of solidification and hot rolling between the roll gaps, and completes it in a very short time (2-3s). . Its advantage is that the molten metal liquid is directly crystallized, cast and rolled through the rotating crystallizer to directly produce aluminum plate products .

Curtain wall aluminum plate: Aluminum veneer curtain wall is made of high-quality high-strength aluminum alloy plate. Its common thickness is 1.5, 2.0, 2.5, 3.0MM, the model is 3003, and the state is H24. Its structure is mainly composed of panels, panels, ribs and corner pieces .

 Process flow from aluminum sheet processing to aluminum curtain wall panels: cutting, perforation, CNC cutting, perforation, planning, arc bending, welding, assembly, polishing, cleaning, painting, inspection and testing, packaging, storage.

The surface of the aluminum curtain wall is generally treated with fluorocarbon spraying after pretreatment such as chrome plating of the aluminum strip. Polyvinylidene fluoride resin (KANAR500) for fluorocarbon paint topcoats and varnishes. Generally divided into two coatings, three coatings or four coatings. Fluorocarbon coatings have excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, have excellent cold resistance, heat resistance, can resist strong ultraviolet radiation, and can maintain long-term non-fading, non-toxic Powdered, timeless.

The aluminum alloy veneer is easy to be processed into arcs and multiple folded edges or sharp angles, which can adapt to today's ever-changing exterior wall decoration needs, and has rich colors. The color can be freely selected according to the design and the owner's requirements, which really broadens the architect's design space.

Ø Advantages of aluminum curtain wall

1. Aluminum curtain wall has good rigidity, light weight and high strength. The aluminum veneer curtain wall panel has good corrosion resistance, and the fluorocarbon paint can last for 25 years.

2. The aluminum curtain wall has good manufacturability. Using the process of processing first and then painting, the aluminum plate can be processed into a variety of complex geometric shapes such as planes, arcs, and spheres.

3. Aluminum curtain wall is not easy to stain, easy to clean and maintain. The non-adhesion of the fluorine coating film makes it difficult for pollutants to adhere to the surface, which has good cleanliness.

4. The installation and construction of aluminum curtain wall is convenient and quick. The aluminum plate is formed in the factory, and there is no need to cut it on the construction site, just simply fix it.

5. The aluminum curtain wall can be recycled and reused, which is conducive to environmental protection. The aluminum plate can be 100% recycled, and the recycling value is higher .
