Overview of aluminium profile and surface treatment
Aluminum anodized electrophoretic spraying composite film has many advantages. Firstly, the thickness of the electrophoretic spraying paint film is very uniform and easy to control accurately. At the same time, it can cover surfaces that are difficult to achieve by electrostatic spraying, which is completely different from electrostatic spraying film and the Aluminium Profile show obvious advantages. In addition, as the bottom layer of the electrophoretic paint film, the aluminum anodized film basically does not have the problem of filamentous corrosion under the film in terms of Aluminium Construction Profiles performance, which is the biggest advantage of the composite film. The results of a long-term Aluminum Extrusion Profile atmospheric corrosion test show that the electrophoretic powder coating film has tested its salt alkali resistance and nitric acid resistance, but no corrosion problems have occurred. Not only did it all pass the performance test, but it is also significantly outperformed the ordinary sealed anodized film. The gloss retention rate of the 5-year atmospheric exposure corrosion test shows that the electrophoretic coating film can be comparable to the fluorocarbon powder coating film,significantly superior to the performance of powder coating and anodized sealing film.
Hard anodized film for Aluminium Profile is an anodizing technology that prioritizes the hardness and wear resistance. Hard anodizing technology not only significantly improves the surface hardness and wear resistance of Aluminum Extrusion Profile, but also enhances their corrosion and heat resistance. The principle, equipment, process, and detection of hard anodizing are not fundamentally different from those of ordinary anodizing. Therefore, the theory and practice of anodizing have guiding significance for hard anodizing technology. However, there are still some different focuses in terms of specific process measures. Therefore, compared with ordinary anodized films, hard anodized films are generally thicker, have higher hardness, and have better wear resistance. The industrial application of Industrial Aluminum Profile anodizing treatment technology has been over 50 years. With the development of the market, the surface treatment technology of aluminum will become more mature and the scale will also become larger.
Aluminium is the most widely used metal materials among non-ferrous metals. In industry and construction, we can see cases of Aluminium Profile application everywhere, and its application scope is constantly expanding. Since the 21st century, China's aluminum extrusion industry has entered a rapidly rising golden period with the accelerated development of the entire aluminum processing industry, and the scale of the aluminium industry has also significantly increased and improved. With the continuous development of the market, the surface treatment of aluminum materials cannot only focus on building aluminum doors and windows, but must also be extended to various forms of aluminum profiles, CNC processed products, etc.
Aluminium Profile and their alloy products have a series of excellent chemical, physical, mechanical, processing properties and characteristics, which enables the rapid development of the Aluminum Extrusion Profile industry. In the process of social and economic development, Aluminium Construction Profiles are usd in variuos industries. Surface treatment technology enables aluminum and its alloys to achieve better surface properties, not only improving and enhancing the physical and chemical properties of aluminum, such as corrosion resistance, chemical resistance, wear resistance and other surface features, but also endowing aluminum surfaces with various colors, greatly enhancing the surface decoration of aluminum. Aluminum surface treatment films can be classified from various perspectives according to production processes,, such as anodized films, electrostatic powder coating films, electrophoretic coating films, etc., and classified according to film layer materials, such as aluminum anodization films, fluorocarbon paint films, etc.
