The quality of the curtain wall aluminum veneer directly affects the quality of the entire building curtain wall, so the quality control of the procurement of plates is the key. Aluminum veneer is generally made of pure aluminum. The thickness of the aluminum veneer commonly used for external walls is generally 2.5 to 3 mm. In order to strengthen the surface strength of the aluminum veneer, a reinforcement rib must be installed on the back of the aluminum plate. The reinforcement rib is made of thick aluminum tape (the reinforcement rib is located by the plate). Calculate its size at different heights), first use a flash welder to weld the screw caps to the back of the aluminum plate, and then insert the aluminum rib drilling holes into the screws and fix them with screws. The back of the aluminum veneer should be reinforced because the aluminum plate will not sag and the second will not bulge under the positive and negative pressure of the outside world. This avoids the vibration sound caused by the repeated vibration of the aluminum veneer inside and outside. If sound insulation is needed, rock wool, slag wool or foam treatment can be placed inside the aluminum plate. Domestic aluminum veneer manufacturers can produce all kinds of aluminum veneers with wide, long, and arc-shaped curtain walls according to user requirements, and weld the reinforcing ribs. The installation of the reinforcing ribs is also very important. Some manufacturers have not effectively connected the reinforcing ribs to the flanges of the aluminum plates, which has destroyed the force transmission effect of the reinforcing ribs and caused the deformation of the plates after use, affecting the facade effect. The surface treatment method of Anhui aluminum veneer products is electrostatic spraying. Spraying is divided into powder spraying and liquid spraying. Powder spraying materials are mainly: polyurethane, expanded resin, epoxy resin and other raw materials with high color retention pigments, can get dozens of different colors of spray powder. The spray powder is resistant to collision and abrasion, and the aluminum plate is deformed under a 50 kg impact. The sprayed layer is free of cracks and layers, intact and intact, and resistant to dilute acids and mortar. The only shortcoming is that it is afraid of long-term ultraviolet radiation, and it is easy to produce a difference in the color of the yin and yang surfaces after a few years. The weight of spray powder produced by many domestic manufacturers varies greatly, and some powders contain gold scraps. After hanging on the wall, this powder changes with the angle of the sun, and changes during the day and dusk. The color of the wall is different. Choose the powder Spray paint should attract attention.
