curtain Introduction to aluminum veneer products
Curtain wall aluminum veneer It is a new and beautiful metal decorative material for building curtain wall, gradually replacing traditional curtain wall materials Mosaic , Marble And sandblasting exterior walls. Curtain wall aluminum veneer has advantages in the use of high-rise building curtain wall because of its light weight and high strength. Because high-rise buildings are always subjected to various loads, especially the wind pressure, the mosaic materials are easy to fall off, and the curtain wall materials with low hardness will be deformed due to the wind pressure. Curtain wall aluminum veneer is widely used based on its unique advantages, and is the main force of new curtain wall decorative materials.
Curtain wall aluminum veneer High quality Aluminum plate It is the base material. The thickness of the base aluminum plate is 2.0mm, 2.5mm, 3.0mm, 4.0mm, 5.0mm and other specifications. The size of the formed workpiece can reach 7500mm * 1500mm * 3000mm (L * W * H). The structure of curtain wall aluminum veneer is mainly composed of panel, stiffener, corner code and other components.

Metal plate curtain wall has been used for decades, and the ones still in use include Aluminum veneer , aluminum plastic composite panel and aluminum honeycomb panel. Among the three materials, aluminum veneer and aluminum composite panel 。 Aluminum veneer appeared earlier. Later, in the late 1960s and early 1970s, aluminum plastic composite panel was invented in Germany, and quickly became popular in most countries.
Aluminum plastic plate and Aluminum veneer What's the difference? Here I will make a simple comparison between the two materials.
Aluminum veneer Generally, 2-4mm thick AA1100 pure aluminum plate or AA3003 aluminum alloy plate is used, and 2.5mm thick AA3003 aluminum alloy plate is generally used in China; Aluminum plastic composite board generally adopts 3-4mm three-layer structure, including two 0.5mm upper and lower PVC or PE sandwiched. We can see from the materials that the cost of the aluminum plastic composite panel is certainly much lower than that of the aluminum veneer. The current market is about that the price of 4mm thick composite board is more than 120 yuan/m2 lower than that of 2.5mm thick aluminum veneer. For a 10000 m3 project, the cost of using aluminum plastic board is 1.2 million yuan lower than that of using aluminum veneer.

At present, the world's Aluminum veneer There are two kinds of materials: aluminum veneer spraying and roller coating. Because aluminum panels need to be shaped before coloring, the processing process of aluminum veneer is generally material spraying production. The spraying production of aluminum veneer is divided into two steps: sheet metal processing is the first step. This process is mainly to process the aluminum veneer into the shape and size required for construction through cutting, folding, arc bending, welding, polishing and other processes on the flat plate. The second step is spraying. Spraying is to spray paint on the processed sheet metal. There are two kinds of spraying: manual spraying and machine spraying. Generally, machine spraying is only suitable for regular plates, but this kind of aluminum veneer is rarely used in actual use, and most domestic manufacturers use manual spraying. Manual spraying is a dangerous job, because the volatility and toxicity of paint are relatively strong, it is easy to cause chronic benzene series
Poison seriously affects people's health. One of the advantages of manual spraying is that the color can be selected regardless of the amount, while the roll coating of aluminum plastic plate must reach a certain amount before processing. The processing process of aluminum plastic plate is more complicated than that of aluminum veneer, mainly including four processes: formation, coating, compounding and trimming. Except trimming, these four processes are all automated production. From its processing, it can be seen that the aluminum plastic plate has certain advantages in environmental protection and safety. In addition, the sheet metal processing process of aluminum veneer is simple, and some private workshops have begun to get involved, which has seriously affected the stability of the market quality of aluminum veneer.
