The treatment process of curtain wall aluminum plate can be divided into two methods: anodizing and electrostatic spraying. The anodized film is generally larger than 12μ, the color is only bronze and white, and the color is monotonous. The more serious disadvantage is that the color of each aluminum plate is different, and many curtain wall panels are combined to form the curtain wall. The overall effect is very ugly. It can be said that this defect cannot be eliminated, not caused by the production process, but because the aluminum plate is not caused by the batch number, the chemical composition, there are small differences, and the factors such as oxidation of the cell current density cannot be exactly the same, so The color after oxidation is different, the single appearance may not be obvious if all the arrangements are obvious. Therefore, the surface treatment must usa 5052 Anodized aluminum plate for curtain wall



Another surface treatment method for curtain wall aluminum plate is electrostatic spraying. Spraying is divided into powder spraying and liquid spraying. The powder coating material is mainly composed of raw materials with high color retention pigments such as polyurethane, swellable resin, epoxy resin, etc., and can obtain dozens of different colors of powder spray. Sprayed powder is resistant to impact and abrasion. Under the impact of 50kg, the aluminum plate is deformed, the sprayed layer has no cracks, no falling layer is complete, and it is resistant to dilute acid and mortar. The only disadvantage is that ultraviolet rays are prone to produce yin and yang color differences. Spray powders produced by many domestic manufacturers have very different weights. Some powders contain gold powder. After hanging the powder on the wall, it changes with the angle of the sun. Day and dusk change, and the color depth of the walls is different. Use powder spray paint to attract attention.
