Product Specification

British Standard Aluminum Panel Metal Glass Curtain Wall for Commercial Office

The aluminum panel curtain wall has a unique texture, rich and durable colors, and the appearance shape can be diversified, and can be perfectly combined with glass curtain wall materials and stone curtain wall materials. Its perfect appearance and excellent quality make it favored by the owners. Its light weight is only one fifth of marble and one third of the glass curtain wall, which greatly reduces the load of the building structure and foundation, and maintenance costs Low, high performance-price ratio. As far as the curtain wall aluminum plates currently used in China are concerned, most of them are composite aluminum plates and aluminum alloy veneers.

Treatment process:

The processing technology of the curtain wall aluminum plate can be divided into two methods, one is anodizing and the other is electrostatic spraying. The anodized oxide film is generally above 12μ, and the colors are only bronze and white. The colors are monotonous. The more serious disadvantage is that the color of each aluminum plate is different. Very ugly. It can be said that this shortcoming cannot be eliminated. It is not caused by production technology, but because the aluminum plate is not made of a batch number, chemical composition, there are small differences, plus factors such as the current density of the electrolytic bath liquid during oxidation cannot be exactly the same, so The color after oxidation is somewhat different, it may not be obvious in a single sheet, if they are all lined up, it is very obvious. Therefore, the surface treatment of the aluminum plate of the aluminum curtain wall must not be anodized.

Another method for surface treatment of curtain wall aluminum plates is electrostatic spraying. Spraying is divided into powder spraying and liquid spraying. Powder spraying materials are mainly: polyurethane, expanded resin, epoxy resin and other raw materials with high color retention pigments, can get dozens of different colors of spray powder. The spray powder is resistant to collision and abrasion, under the impact of 50 kg, the aluminum plate is deformed, the sprayed layer is free of cracks, the layer is not damaged, and it is resistant to dilute acid and mortar. The only shortcoming is that it is afraid of long-term ultraviolet radiation, and it is easy to produce a difference in the color of the yin and yang surfaces after a few years. The spray powders produced by many domestic manufacturers vary greatly in weight. Some powders contain gold shavings. After being hung on the wall, the powder changes with the angle of the sun, changes during the day and dusk, and the color of the wall varies. Use powder spray paint to draw attention.

Aluminum alloy veneer is generally 2 ~ 4mm aluminum alloy plate. When it is made into a wall board, it is first processed according to the requirements of the secondary design, directly folded, and the four corners are welded into a closed groove by high pressure, and the wall board The fixing bolts of reinforcing ribs are reserved on the back by means of electric welding and nail planting. After the sheet metal work is completed, the fluorocarbon paint is sprayed, usually two coatings and three coatings, with a thickness of 30 to 40 μm. Aluminum alloy veneer is easy to be processed into arcs and multiple folds or acute angles, which can meet the needs of today's ever-changing exterior wall decoration, and it is rich in color. It can be arbitrarily selected according to the design and owner's requirements, which truly broadens the architect Design space.
