New energy-saving color aluminum doors and windows

New energy-saving color aluminum doors and windows At present, the world's advanced industrial countries more commonly use color energy-saving aluminum alloy doors and windows, such as Japan, the United States, Germany, Italy and other countries in the construction project occupies a large proportion, and the technology is more mature. China's new color energy-saving aluminum doors and windows in the 90s just started, with the rapid increase in people's consumption levels in recent years, the continuous development of materials science and technology, new energy-saving aluminum doors and windows in the big cities are also gradually used. The main feature of the color energy-saving aluminum doors and windows is that the surface of the profile is painted with acrylic paint, fluorocarbon paint or polyurethane powder spray, and the aluminum profile is covered with a beautiful coat. This new type of aluminum material not only has a beautiful color, but also has the advantages of anti-dust, anti-powdering, anti-ultraviolet radiation and no fading. Moreover, the coating film with a thickness of 60-70u can reduce the heat conduction. The sound insulation is about 30Db. This new type of energy-saving aluminum profile has a non-metallic interlayer cold bridge, which is mainly divided into three types. One is to wear glass fiber reinforced nylon strip to cut off heat, and the second is to inject polyurethane foam material in the middle of the profile. The third type is heat insulation in the middle of the profile. The glass is a low-heat-conducting hollow glass and adopts two-way sealing. The hardware opening part is a high-grade multi-point locking mechanism. Its physical properties are: resistance to wind pressure deformation is I; watertight performance is II; airtight performance is I; heat transfer coefficient is k
