Recently our company has undertaken a curtain wall project in the United States, including fluorocarbon aluminum veneer, curtain wall glass, and curved aluminum veneer.The total value of the goods is about 5 million USD
The aluminum veneer curtain wall is made of high-quality high-strength aluminum alloy plate, and 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 pre-burying board, panels, reinforcing ribs and angle code. The pre-burying board is connected to the structure by bolts and is stressed, and the corner code can be directly bent and stamped from the panel, or it can be formed by riveting the corner code on the small side of the panel. The reinforcing rib is connected with the electric welding screw behind the panel (the screw is directly welded on the back of the panel), making it a solid whole, which greatly enhances the strength and rigidity of the aluminum veneer curtain wall and ensures the smoothness in long-term use. strength and wind resistance. If sound insulation and insulation are required, efficient sound insulation and insulation materials can be installed on the inside of the aluminum plate
Aluminum veneer is divided into two types in terms of specifications: the thickness of aluminum veneer ess than 1.2mm that is called aluminum square plate, and the thickness of aluminum veneer more than 1.5mm that is called aluminum buckle plate (also called aluminum veneer) and aluminum curtain wall
The surface of the aluminum panel curtain wall is generally treated with fluorocarbon spraying after pre-treatment such as chroming. Polyvinylidene fluoride resin (KANAR500) for fluorocarbon paint topcoats and varnishes. Generally divided into two coats, three coats or four coats. Fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, excellent cold and heat resistance, can resist strong ultraviolet radiation, and can maintain long-term non-fading and non-pulverizing ,long lasting.
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 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 recycled 100%, 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, high performance price ratio.
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. No chromatic aberration and excellent on-site machinability, it provides conditions for dealing with external wall dimensional changes caused by on-site construction errors, reducing workshop processing cycles and shortening installation time.
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 and 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. Aluminum alloy veneer is easy to be processed into arc and multi-fold edges or acute angles, which can adapt to the needs of the ever-changing exterior wall decoration. Moreover, it is rich in color, and can be arbitrarily selected according to the requirements of the design and the owner, which really broadens the design space of architects
