ã€ALUMINIUM NETWORK】Aluminum plates, plate-type materials made of aluminum or aluminum alloy materials, or plate-type materials manufactured by the process of heating, rolling, straightening, or solid-solution aging of flat alumina embryos Aluminum products.
Aluminum plates used in construction include single-layer aluminum plates, composite aluminum plates, and other materials. Generally, they are often referred to as single-layer aluminum plates (also called single aluminum plates or pure aluminum plates). They are mostly used in architectural decoration projects. Aluminum curtain walls are a type of curtain wall. They are simple. To say that the curtain wall is made of aluminum instead of glass. Aluminum curtain walls are mostly used for wall protection and non-lighting walls, and foreign aluminum curtain walls have always used single-layer aluminum panels. As for aluminum curtain walls currently used in China, the use of single-layer aluminum panels is more common, because they can obtain a variety of colors of the spray surface, good strength, low cost, long life, if not in direct contact with steel, aluminum hanging on the wall In the past, it will not fall off and erode in 50 years.
Composite aluminum plate and aluminum alloy veneer comparison
Materials
Composite aluminum plate: two layers of 0.5mm thick aluminum plate sandwiched between PVC or PEC plastic roll, heat together.
Aluminum alloy single board: 2 - 3mm aluminum alloy board.
Fluorocarbon coating
Composite aluminum plate: one-off roll printing, coating thickness is generally 20μm.
Aluminum alloy veneer: 2 or 3 sprays are completed, and the coating thickness is generally 30-40μm.
colour
Aluminium composite panels: Choose from a wide range of colors, primary color systems in monochrome, and magic color systems. Patented color products have a film layer on the surface that provides excellent durability and good color identity.
Aluminum alloy veneer: Any color can be selected according to the design and owner's requirements.
life
Composite aluminum plate: domestic plate about 10 years, import plate color and strength up to 20 years, maintenance-free.
Aluminum alloy veneer: more than 15 years, due to the climate caused by wind pressure deformation, the board color to spend.
Confined
Composite aluminum plate: four corners.
Aluminum alloy veneer: Four corners welded closely.
Wind resistance
Composite aluminum plate: Small deformation resistance to wind pressure, high wind pressure resistance of imported composite plate.
Aluminum alloy veneer: The wind pressure deformation is large, easily deformed.
Temperature change resistance
Composite aluminum plate: The composite plate processed by common plastic processing technology has a large difference in expansion coefficient between aluminum plate and plastic, and is prone to blistering and peeling.
Aluminum alloy veneer: the same material, when the temperature changes, the wall plate itself has no effect.
Lightning resistance
Composite aluminum plate: not resistant to lightning, strong current is difficult to ground through the composite aluminum plate, 0.5mm thick aluminum plate will be broken down.
Aluminum alloy veneer: It can be used as a good conductor of electricity. It quickly transports lightning currents to the ground through building grounding systems.
Processability
Composite aluminum plate: can be processed on site and can cope with dimensional changes brought about by on-site construction errors.
Aluminum alloy veneer: Made by the production plant, it is poorly adapted to the error of the on-site construction and requires high secondary design.
Product rate
Composite aluminum: generally 80% - 95%.
Aluminum alloy single board: 100%.
Yield
Composite aluminum plate: Hand-operated planer at the site, if the depth of the slot is not well controlled, it will injure the outer aluminum plate, causing breakage of the bend, resulting in waste, and the yield is generally 96%-98%.
Aluminum alloy veneer: Made by the production plant, the finished product rate is 100%.
Construction Quality
Composite aluminum plate: Because the wall plate is mostly processed on the spot, poor quality control conditions, cutting corners, and shoddy materials are easy to appear in this link, the quality of the wall plate will affect the construction quality.
Aluminum alloy veneer: The production plant controls the production quality according to the international standards, and the quality of the wall plate is reliable, providing the prerequisite for ensuring the construction quality.
Environmental protection
Composite aluminum plate: The selection of the core material, the general core material will produce harmful gases in case of high temperature, not fireproof, difficult to recycle.
Aluminum alloy veneer: Fireproof, easy to recycle, no pollution to the environment.
Scope of application
Composite aluminum plate: suitable for curtain wall engineering.
Aluminum alloy veneer: Suitable for facade decoration, elevated corridors, pedestrian bridges, and low-rise curtain walls.
The building curtain wall market is increasingly rich in products, forming a diversified market structure dominated by four major materials, namely aluminum, plastic, wood, and steel. The application of new materials and new technologies will lead to more new products. Compared with other industries, aluminum curtain wall products have less product differentiation and more intense competition. The appearance of aluminum curtain wall can be diversified, and it can be perfectly combined with glass curtain wall material and stone curtain wall material. Its light weight, only one-fifth of marble, is one-third of the glass curtain wall, significantly reducing the building structure and the underlying load, but also the low maintenance cost, high performance and price ratio.
The surface of the aluminum curtain wall is generally subjected to pretreatment such as chromizing and then treated with fluorocarbon spraying. The fluorocarbon coating has excellent corrosion resistance and weather resistance, is resistant to acid rain, salt spray and various air pollutants, is excellent in resistance to cold and heat, and is resistant to strong UV radiation, and can maintain long-term non-fading and long service life. .
Affected by the energy conservation policy, the domestic product structure of aluminum curtain walls will be greatly changed. The aluminum alloy curtain wall is still dominated by open frame, hidden frame and aluminum curtain wall. The unit type curtain wall has good development prospects in large and medium-sized cities. The aluminum alloy double-layer, intelligent and sun visor curtain walls will gradually mature and improve. The market share of aluminum curtain walls in the curtain wall market will remain at more than 55%, and the product structure will undergo major changes. Affected by the national building energy conservation policy and the energy crisis, the proportion of energy-saving and environmentally friendly aluminum curtain walls will be greatly increased.
