(1) What is aluminum veneer? Aluminum veneer is a type of building decoration material, mainly composed of panels, reinforcing bars, corner brackets, and other components. Aluminum veneer is made of high-quality aluminum alloy sheet as the substrate; The surface is usually treated with pre-treatment such as chrome plating, and then treated with fluorocarbon spraying; Corner codes can be directly formed by bending and stamping the panel, or by riveting corner codes on the small edges of the panel. Is aluminum sheet aluminum veneer? The aluminum plate is a pure metal plate, and the aluminum veneer is a composite material with a layer of foam on the thin aluminum plate.
1. Common specifications for aluminum veneer: ① Common specifications for interior wall aluminum veneer include 1200mm * 1800mm and 600mm * 1200mm. ② The commonly used sizes for aluminum veneer ceilings are 600mm * 600mm, 300mm * 300mm, etc The specifications and dimensions of the exterior aluminum veneer are not fixed, and can be processed and formed according to the design dimensions. The width should prioritize specifications of 1.5m or less, and the length is not recommended to exceed 6m.
2. Conventional thickness of aluminum veneer: ① Outdoor aluminum veneer thickness: generally choose 2.5mm and 3.0mm. ② The outdoor ground floor and podium section: generally choose a thickness of 2.0mm Indoor wall aluminum veneer or indoor ceiling aluminum veneer: generally choose the thinnest thickness of 1.0mm or 1.5mm
(3) Aluminum veneer material: The aluminum veneer is made of high-quality high-strength aluminum alloy sheet, with commonly used thicknesses of 1.5, 2.0, 2.5, and 3.0mm. The model is 3003 and the status is H24. The maximum size of conventional materials is 1220mm × 2440mm.
Aluminum veneer is widely used in various fields such as building curtain walls, interior decoration, lobby facades, indoor irregular ceilings, pedestrian bridges and corridors, rain shelters, airports, stations, hospital conference halls, opera houses, sports venues, beams and columns, balconies, partition decorations, advertising signs, vehicles, furniture, exhibition booths, instrument casings, subways, and shipping tools.

(5) Aluminum veneer type 1, aluminum fluorocarbon veneer
The outdoor environment is complex, with high temperature baking, wind and rain, as well as occasional acid rain and salt spray. Only fluorocarbon aluminum veneer can withstand such harsh weather conditions and stand undefeated in construction. The fluorocarbon aluminum veneer has been carefully coated and tested. Before leaving the factory. This type of veneer is timely exposed to extremely harsh external environments, and its surface will not exhibit powdery paint film phenomenon. It has practical advantages such as good durability and strong corrosion resistance.
2. More and more people prefer to use wood grain aluminum veneer in their home and office decoration to meet their expectations. Returning to nature, everything is simple, and the imitation wood color expresses a natural decorative atmosphere, giving people a comfortable and relaxing feeling. Zhengyi Building Materials aluminum veneer has rich and vivid wood grain, clear and natural texture. Long term exposure to sunlight without fading, cracking, peeling, or deformation. It has good aging resistance and weather resistance. Widely used in the interior and exterior decoration of subways, high-speed train stations, airports, large shopping malls, corridors, leisure places, public health clinics, building facades, office buildings, hotels, shopping malls, office buildings, and exhibition centers.
3. The colors of colored aluminum veneer are not only white, gray, red, yellow, etc. The colors of wood and stone can also be included. By various techniques, the required pattern colors are attached to the surface of the double veneer, which is conducive to fully unleashing the imagination of architects. Aluminum plastic panel manufacturers have studied the process of multi-color fluorocarbon spray coating and developed dual color aluminum veneer. It has been used outdoors for more than ten years, breaking the limitations of traditional multi-color screen printing fading technology after three months of outdoor use. Multi color aluminum veneer is widely used in outdoor curtain walls, indoor curtain walls, ceilings, cinemas, hospitals and other places.
4. Plastic aluminum veneer is favored by developers as it is movable and replaceable in many large public places or large building decoration materials. In order to ensure that every construction project has its unique appearance, Jinrui provides customers with a wide range of design styles, materials, and colors for plastic aluminum veneers. It can be processed into various types of boards, with the addition of concave, convex, curved, etc. as desired. It provides valuable design creativity and visual feast for architects, and plastic aluminum panels have high artistic value and prospects, appreciating performance.

?。?) Advantages and disadvantages of aluminum veneer
1. The advantages of aluminum veneer are (1) light weight, good rigidity, and high strength. Aluminum veneer is lighter than traditional stone, glass, etc., with a 3.0mm thick aluminum plate weighing 8kg/㎡ and a tensile strength of 100-280n/mm2. (2) Good durability and corrosion resistance. PVDF fluorocarbon paint based on kynar-500 and hylur500 can last for 25 years without fading. (3) Good craftsmanship. By adopting the process of processing before painting, aluminum plates can be processed into various complex geometric shapes such as flat, curved, and spherical shapes. (4) Uniform coating and diverse colors. Advanced electrostatic spraying technology ensures uniform and consistent adhesion between paint and aluminum plates, with diverse colors. It can also be used for various grain transfer printing such as wood grain, stone grain, blue and white porcelain, as well as 3D pattern printing, with a large selection space. (5) Not easy to stain, easy to clean and maintain. The non adhesiveness of fluorine coating film makes it difficult for pollutants to adhere to the surface, and it has better cleaning properties; If it gets dirty, you can directly wipe it with a cloth and water, or various cleaning agents. (6) Installation and construction are convenient and fast. Aluminum plates are formed in the factory and do not need to be cut on the construction site. They can be fixed on the skeleton. No professional construction personnel are required, it can be directly installed on rough walls or tiles, and can also be used for renovation and renovation of old buildings, saving time, effort and trouble. 7. Recyclable and reusable, beneficial for environmental protection. Aluminum panels are different from decorative materials such as glass, stone, ceramics, aluminum-plastic panels, etc., and have a high recycling residual value.
2. Disadvantages of aluminum veneer: (1) The metal fatigue of aluminum veneer is poor. The principle of metal fatigue is: how many times can a metal withstand vibrations at a certain amplitude? If the vibration exceeds this limit, the metal's fatigue limit will be exceeded, and deformation will occur. If the amplitude is large, deformation will occur directly. If the amplitude is small, the number of vibrations can be infinite. For example, aluminum cola cans can easily be pinched open, while steel fruit cans are safe and sound. (2) Low elastic modulus. Alloys have different elastic moduli, and the elastic modulus also varies with temperature. The higher the temperature, the smaller the elastic modulus.
