Curtain wall aluminum
profile refers to the high-quality and high-strength aluminum alloy sheet used to make curtain walls, because aluminum is the most used metal structure material in the construction industry after steel. The main projects that use aluminum in the construction industry are aluminum doors, windows and curtain walls. Because aluminum has good material properties, such as low density (2710kg/m3), suitable strength, good chemical stability, easy to keep clean, high conductivity, good radiation performance, suitable for anodizing, and easy to process. Aluminum can change the properties of aluminum in a wide range through additives such as magnesium (Mg), manganese (Mn), copper (Cu), silicon (Si) and some other elements, making a variety of aluminum alloy materials with superior properties. The process of forming aluminum alloy profiles: bauxite, and then to pure aluminum. Pure aluminum is extracted from the ore through a two-stage refining method. The first-stage refining method is called the Bavarian refining method. This method uses a chemical process: from aluminum and vanadium. Alumina powder is extracted from the soil. Every two tons of bauxite can provide one ton of alumina. The second level is called fusion electrolysis, which is to put alumina into a high-temperature molten pool to melt, and turn on the current to decompose it into oxygen and aluminum. One ton of pure aluminum can be extracted for every two tons of alumina. Pure aluminum is also called electrolytic aluminum, and its purity is between 99.5% and 99.8%, which is the final product of smelting aluminum. curtain wall profiles generally use 6063-T5 aluminum-magnesium-silicon alloy. The production process is to add the required chemical components to the pure aluminum ingot solution, and continuously 'cast' into various specifications of aluminum alloy bars. Considering the influence of chemical composition on mechanical properties, it is necessary to adjust the content ratio of magnesium to silicon to 1.73:1. In particular, excess magnesium will reduce the strength of aluminum alloy materials; excess silicon will damage the extrusion performance and electrolytic coloring performance of aluminum, and too little silicon will reduce the mechanical properties of the profile; excessive iron content will cause the extrusion of the profile. The surface will be rough, which will affect the gloss of the oxide film and increase the color difference. The iron content must be strictly controlled to reduce it to the minimum range; too high zinc and copper content will significantly reduce the appearance quality of the oxide film, so The adjustment of the chemical composition during casting must be carried out strictly according to the requirements. curtain wall aluminum profile features: made aluminum veneer curtain wall panels have good rigidity, light weight and high strength. The aluminum veneer curtain wall panel has good corrosion resistance, and the fluorocarbon paint can last for 25 years. The aluminum veneer curtain wall panels produced by have good craftsmanship. The aluminum plate can be processed into a variety of complex geometric shapes such as plane, arc and spherical surface by adopting the process of processing first and then spraying paint. The aluminum veneer curtain wall panel made by is not easy to be stained and is easy to clean and maintain. The non-adhesiveness of the fluorine coating film makes it difficult for contaminants to adhere to the surface, and it has good cleanliness. The aluminum veneer curtain wall panel made by is convenient and quick to install and construct. The aluminum plate is formed in the factory, and the construction site does not need to be cut and simply fixed. The aluminum veneer curtain wall panels made by can be recycled and reused, which is good for environmental protection. The aluminum plate can be recycled 100%, and the recycling value is higher. The application range of aluminum veneer curtain wall made of curtain wall aluminum profile is: aluminum veneer curtain wall is suitable for all kinds of building interior and exterior walls, lobby facades, column decorations, elevated corridors, pedestrian bridges, elevator edging, balcony packaging, advertising signs, indoor special shapes Decoration such as ceiling.
