Aluminum plate is widely used in building decoration industry. It has good aesthetics and corrosion resistance. In order to ensure its good performance, it is necessary to carry out surface treatment in the processing process. The following aluminum plate manufacturers will introduce several surface treatment methods.
The aluminum curtain wall is made of two layers of 0.5mm thick pure aluminum plates sandwiched between PVC or PEC plastics and rolled and heat sealed. Aluminum alloy veneer - 2 ~ 3mm aluminum alloy plate. In terms of color, gray has more choices. Specific colors need to be processed in large quantities. Good color uniformity and high directivity.
The surface of aluminum curtain wall shall be subject to fluorocarbon spraying after chrome plating and other pretreatment. Fluorocarbon coating is made of polyvinylidene fluoride resin plus top coat and varnish. Aluminum plate manufacturers believe that the fluorocarbon coating treated in this way has good corrosion resistance and weather resistance, can resist acid rain, salt fog and various air pollutants, has good cold and heat resistance, can resist strong ultraviolet radiation, and will not fade or powdered for a long time.
Processing mainly includes reinforcement, corner code and surface phenomenon spraying. The corner code can be bent and stamped directly from the panel, or it can be formed by riveting the corner code on the small edge of the panel. The reinforcing rib is connected with the electric welding screw behind the plate (the screw is directly welded on the back of the plate), making it a solid whole.
The surface treatment of curtain wall aluminum plate can be divided into two methods: anodic oxidation and electrostatic spraying. The anodic oxide film is generally larger than 12, with only two colors, bronze and white, and the color is monotonous. Because the aluminum plate is not composed of one batch number, and there is little difference in chemical composition, and factors such as the current density of the electrolyzer liquid cannot be the same during the oxidation process, the color after oxidation may be different, which may not be obvious in a single plate, but it is very obvious if they are all arranged together. Therefore, anodic oxidation shall not be used for the surface treatment of aluminum curtain wall.
Another method for surface treatment of curtain wall aluminum plate is electrostatic spraying. Spraying is divided into powder spraying and liquid spraying. Powder spraying materials mainly include polyurethane, polyexpandable resin, epoxy resin and other raw materials with high color retention pigments. Dozens of different colors of spraying powders can be obtained. Spray powder impact resistant, wear-resistant, dilute acid resistant and mortar.
