How long is the service life of aluminum veneer?
Aluminum veneer refers to the building decoration material formed by processing after chromium treatment and then using fluorocarbon spraying technology. Fluorocarbon coatings mainly refer to polyvinylidene fluoride resin (KANAR500), divided into primer, top paint, varnish three kinds. The spraying process is generally divided into two, three 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, can maintain long-term color, no powder, long service life.
Light weight, good steel, high strength 3.0mm thick aluminum plate per square plate weight 8kg, tensile strength 100-280n/mm2. Good durability and corrosion resistance. pvdf fluorocarbon paint with kynar-500 and hylur500 as the base material can be used for 25 years without fading. Good manufacturability. Using the process of first processing and then painting, the aluminum plate can be processed into a variety of complex geometric shapes such as plane, arc and sphere. Uniform coating, diverse colors. Advanced electrostatic spraying technology makes the adhesion between paint and aluminum plate uniform, diverse colors, large choice space.
Easy to stain, easy to clean and maintain. The non-adhesion of fluorine coating film makes it difficult to attach pollutants to the surface and has good cleaning property. Convenient installation and construction. The aluminum plate is formed in the factory, and the construction site does not need to be cut, and it is fixed on the skeleton. Recyclable and environmentally friendly. Aluminum plate can be 100% recycled, different from glass, stone, ceramic, aluminum-plastic plate and other decorative materials, recycling residual value is high. The application of metal plate curtain wall has been decades of history, and there are still three kinds of aluminum veneer, aluminum-plastic composite board and aluminum honeycomb board in use. Among these three materials, the most commonly used are aluminum veneer and aluminum-plastic board. Aluminum veneer generally uses 2-4mm thick AA1100 pure aluminum plate or AA3003 and other high-quality aluminum alloy plate, the domestic general use of 2.5mm thick AA3003 aluminum alloy plate; Aluminum-plastic composite panels generally use a 3-4mm three-layer structure, including the upper and lower two 0.5mm PVC or PE. We can see from the material that the cost of aluminum-plastic composite board is certainly much lower than that of aluminum veneer. The market is about 4mm thick composite board than 2.5mm thick aluminum veneer price is more than 120 yuan/square, a 10,000 square project, the use of aluminum-plastic board than the use of aluminum veneer to reduce the cost of 1.2 million yuan.
