The aluminum veneer curtain wall is made of high-quality high-strength aluminum alloy plate. 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 panels, ribs and corner codes. The corner code can be bent or stamped directly from the panel, or it can be angled on the small side of the panel. The ribs and the welding screws behind the board (the screws are directly welded to the back of the board) make it a solid whole, which greatly enhances the strength and rigidity of the aluminum veneer curtain wall, ensuring the flatness in long-term use. Degree and resistance to wind and earthquake. If sound insulation is required, efficient sound insulation can be installed inside the aluminum plate.
The surface of the aluminum curtain wall is generally pretreated by chromization and then treated with fluorocarbon. Fluorocarbon coatings and varnishes of polyvinylidene fluoride resin (KANAR500). 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, has excellent cold and heat resistance, can resist strong ultraviolet radiation, and can maintain no fading and no powder for a long time. ,long lasting.
