Features of aluminum curtain wall

1. The aluminum panel 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 not fade for 25 years. 2. The aluminum panel curtain wall has good craftsmanship. Using the process of first processing and then painting, the aluminum plate can be processed into various complex geometric shapes such as plane, arc and spherical surface. 3. The aluminum panel curtain wall is not easy to be stained, and it is easy to clean and maintain. The non-adhesive properties of the fluorine coating film make it difficult for contaminants to adhere to the surface and have good cleaning properties. 4. The installation and construction of the aluminum panel curtain wall is convenient and quick. The aluminum plate is formed in the factory, and the construction site does not need to be cut and only needs to be simply fixed. 5. The aluminum panel curtain wall can be recycled and reused, which is beneficial to environmental protection. The aluminum plate can be 100% recyclable, and the recycling value is higher. The aluminum panel curtain wall has a unique texture, rich and durable color, and can be diversified in appearance and shape, 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 owners. Its light weight is only one-fifth of marble and one-third of glass curtain wall, which greatly reduces the load of building structure and foundation, and the maintenance cost. Low, performance-to-price ratio is high. As far as the aluminum curtain wall currently used in China is concerned, most of them are composite aluminum panels and aluminum alloy veneers. The composite aluminum plate is made of two layers of 0.5mm pure aluminum plate (0.2-0.25mm for indoor use) and polyethylene (PE or polyvinyl chloride PVC) with a thickness of 3-4mm in the middle layer. Flat plate, such as 1220mm×2440mm. The fluorocarbon paint on the surface of the external composite aluminum plate is also completed by roller coating, rolling and heat sealing at one time. The thickness of the coating is generally about 20 μm. It has no chromatic aberration and has excellent on-site processability, which provides conditions for dealing with the changes in the dimensions of the exterior walls caused by on-site construction errors, reducing the workshop processing cycle and shortening the installation period. The composite aluminum plate should be processed into a wallboard during installation. First, the board should be cut according to the size of the secondary design. When cutting the board, the size of the folded edge should be considered. Generally, about 30mm is added on each side. According to the curtain wall According to the installation company, the finished product rate of the cutting board is generally 60% to 70%. The cut composite board needs four-side planing, that is, cutting off the inner aluminum plate and plastic layer of a certain width, leaving only the outer aluminum plate with a thickness of 0.5mm, and then folding the edges into a 90-degree outside angle, and then using aluminum profiles to make the same size The auxiliary frame is placed in the bent groove of the aluminum-plastic plate. The bottom surface of the auxiliary frame is bonded to the back of the aluminum-plastic plate with structural adhesive, and the folded four sides are fixed on the outside of the auxiliary frame by riveting, and the middle of the auxiliary frame is generally required. There are reinforcing ribs to ensure the mechanical strength of the wall panel. The reinforcing ribs are made of aluminum and are bonded with structural adhesive. Some informal methods are only fixed by adding aluminum corners to the four corners of the composite panel. The reinforcing ribs are bonded with double-sided tape. Its firmness Great discount. The aluminum alloy veneer is generally an aluminum alloy plate of 2 to 4 mm. When it is made into a wall panel, the sheet metal processing is first performed according to the requirements of the secondary design, and the edges are directly folded. The four corners are welded into a tight groove shape by high pressure. The fixing bolts of the reinforcing rib are reserved on the back by means of electric welding planting nails. After the sheet metal work is completed, the fluorocarbon paint is sprayed. Generally, there are two coats and three coats, and the thickness of the paint film is 30-40μm. The aluminum alloy veneer is easy to be processed into arcs and multi-folded edges or acute angles, which can meet the needs of today's ever-changing exterior wall decoration, and is rich in colors, which can be arbitrarily selected according to the design and the owner's requirements, which truly broadens the scope of architects. their design space.
