Use of aluminum veneer Aluminum veneer is currently widely used in building curtain walls, interior decoration, lobby facades, indoor special-shaped ceilings, overpass corridors, awnings, airports, stations, hospital conference halls, opera houses, sports Venues, beams and columns, balconies, partition decorations, advertising signs, vehicles, furniture, exhibition stands, instrument casings, subways, shipping tools and other fields.

Aluminum veneer types Aluminum fluorocarbon veneer

The outdoor environment is complex, or high temperature baking, or wind and rain, as well as acid rain and salt spray occur from time to time, only fluorocarbon aluminum veneer The panels can withstand such harsh weather tests and remain invincible in the building. Fluorocarbon aluminum veneer has been carefully painted and tested. before leaving the factory. This kind of veneer is exposed to extremely harsh external environments in time, and no powdery paint film will appear on its surface. It has practical advantages such as good durability and strong corrosion resistance.

Wood grain aluminum veneer More and more people like to use wood decorative style in home and office decoration to meet their expectations. Returning to nature, everything is simple, and the imitation wood color shows a natural decorative atmosphere, giving people a comfortable and relaxing feeling. Zhengyi Building Materials aluminum veneer has rich and vivid wood grains, and the texture is clear and natural. It will not fade, crack, fall off or deform under the sun for a long time. Has good anti-aging and weather resistance. It is widely used in the interior and exterior decoration of subways, high-speed train stations, airports, large shopping malls, corridors, leisure places, public health rooms, building exterior walls, office buildings, hotels, shopping malls, office buildings, and convention and exhibition centers.

Colored aluminum veneer The color of aluminum veneer is not only white, gray, red, yellow, etc. Wood and stone colors can also be included. Through various processes, the required pattern color is attached to the surface of the double veneer, which is conducive to giving full play to the architect's imagination. Aluminum-plastic panel manufacturers have studied the multi-color fluorocarbon spray coating process and developed a two-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 .

Among the selection of decorative materials for many large public venues or large buildings, the plastic aluminum veneer is removable and replaceable, and is favored by developers.

Advantages and Disadvantages of Aluminum Veneer Advantages of Aluminum Veneer 1. Light weight, good rigidity and high strength. Aluminum veneer is lighter than traditional stone, glass, etc. The 3.0mm thick aluminum plate weighs 8kg/_ and has a tensile strength of 100-280n/mm2.

2. Good durability and corrosion resistance. PVDF fluorocarbon paint using kynar-500 and hylur500 as base materials can be used for 25 years without staining.

3. Good craftsmanship. Using the process of first processing and then spray painting, the aluminum plate can be processed into various complex geometric shapes such as plane, arc and spherical surfaces.

4. The coating is uniform and the colors are diverse. The advanced electrostatic spraying technology enables uniform adhesion between the paint and the aluminum plate and a variety of colors. It can also be used for various texture transfers such as wood grain, stone grain, blue and white porcelain, and 3D pattern printing, so there is a wide choice.

5. Not easy to stain, easy to clean and maintain. The non-adhesive nature of the fluorine paint film makes it difficult for pollutants to adhere to the surface, and it has good cleanliness; if it is dirty, it can be scrubbed directly with cloth and water, or various detergents.

6. Installation and construction are convenient and fast. The aluminum plates are formed in the factory and do not need to be cut at the construction site, just fixed on the frame. It does not require professional construction personnel and can be installed directly on rough walls or ceramic tiles. It can also be used for renovation of old buildings, etc., saving time, effort and trouble.

7. It can be recycled and reused, which is beneficial to environmental protection. Aluminum panels are different from glass, stone, ceramics, aluminum-plastic panels and other decorative materials, and have a high recycling residual value.

Disadvantages of aluminum veneer 1. The metal fatigue resistance of aluminum veneer is poor. The principle of metal fatigue is: how many times a metal can withstand vibrations at a certain amplitude. If the number exceeds this number, the fatigue limit of the metal is exceeded, and deformation will occur. If the amplitude is large, it will directly deform. If the amplitude is small, the number of vibrations will occur. You can hit unlimited times. For example, the aluminum Coke can was easily pinched, while the steel fruit can was intact.

2. Low elastic modulus. The elastic modulus of different alloys is also different, and the elastic modulus also changes with temperature. The higher the temperature, the smaller the elastic modulus.

The difference between aluminum veneer and aluminum-plastic plate

1. Different concepts: Aluminum veneer refers to the aluminum veneer that has been processed by chromating and then using fluorocarbon spraying technology. Building decoration materials; aluminum-plastic composite panels are composed of multiple layers of materials. The upper and lower layers are high-purity aluminum alloy panels, and the middle is a non-toxic low-density polyethylene (PE) core panel. A protective film is also pasted on the front.

2. The number of layers is different: When studying aluminum veneer and aluminum-plastic panels, you can look at the number of layers. If it is two-layered, it is an aluminum veneer. The first layer is made of aluminum skin, and the second layer is generally made of plastic. But the aluminum-plastic panel has one more layer, because its first and third layers are made of aluminum skin, but the middle one is made of plastic, so it obviously has one more layer.

3. Different processing procedures: Aluminum veneers are processed and formed in the factory. They can be processed according to the size and shape of ceilings, columns, and wall divisions, and complete bending and forming, welding reinforcement, and installation of corner codes, chemical After cleaning, baking and curing processes, the finished product is transported to the site for direct positioning and installation. The plasticity of aluminum-plastic panels is very strong. If slotting is required, aluminum-plastic panels can be selected. The aluminum-plastic panels are cut, bent, and pasted on site. Reinforcing ribs, but the loss is greater.

4. The quality is different: the quality is also different. It is precisely because the aluminum-plastic panel has an extra layer of aluminum skin than the aluminum veneer, so its resistance is better and the quality is more outstanding; Compared with the two, the service life of aluminum-plastic panels is short, while the service life of fluorocarbon sprayed aluminum veneers is more than 20 years.

5. Prices are different: Prices are also different. If we simply compare the prices of the materials themselves, aluminum veneers of the same specifications and thickness are much more expensive than aluminum-plastic panels.

6. Fire protection performance: Aluminum veneer has a certain thickness and does not burn itself, which can meet the fire protection requirements of high-rise buildings; the surface aluminum plate of early aluminum-plastic panels is thin and flammable in case of fire, and the PE interlayer will release when burning Toxic gases. With the advancement of aluminum-plastic panel technology, the fire-proof aluminum-plastic composite panels produced today have greatly improved fire resistance due to the addition of non-toxic flame-retardant materials to their PE, which can fully meet the needs of engineering fire protection.

7. Design structure: Aluminum veneer can be welded, so it can be suitable for diverse building forms, easy to reflect design creativity, and is not restricted by multi-dimensional shapes. The bottom bracket is made of metal to increase strength; aluminum-plastic plate Only two-dimensional deformation processing can be guaranteed, and arc-shaped hemming cannot be completed. Details>>

Purchase of aluminum veneer 1. Observe its shape: The size of the aluminum veneer should be standardized and neat, the thickness should be uniform, the surface should be smooth, and the plate shape should be straight. High-quality aluminum veneers have strict selection of aluminum raw materials and few impurities. The aluminum veneers will not deform even after being sprayed at high temperatures. The processing equipment and management of sheet metal processing all affect the flatness of the aluminum veneers.

2. Smell it: Peel off the aluminum plate and there should be no pungent smell of organic solvents.

3. Look at the thickness: The wall thickness of high-quality aluminum veneers is uniform, and the aluminum veneers are tightly bonded. The quality and thickness of the aluminum veneers can meet national standards. According to national standards, the thickness of exterior wall panels should be 4 mm and the thickness of interior wall panels should be 3 mm. The aluminum panels of exterior wall panels are obviously harder than the aluminum panels of interior wall panels.

4. Look at the spraying process: High-quality aluminum veneer requires the use of the top aluminum veneer spraying line. There will be no penetration of metal and non-metallic debris during the spraying process. The process precision is high and the surface layer And the inner layer feels smooth and smooth, without any spots.

5. Peeling test: The aluminum veneer and the core layer should be difficult to peel off. After peeling off, there should be a roughened film on both the aluminum plate and the plastic core material.

6. Usage occasions: The surface treatment of aluminum veneer includes powder spraying, fluorocarbon spraying, etc. According to the use environment, powder spraying can generally be used for indoor use, while outdoor use has to withstand various harsh natural conditions. The environment and sunlight must be sprayed with fluorocarbon to ensure that the aluminum veneer does not discolor or oxidize for a long time.

7. Aluminum veneer brand: There are many aluminum veneer manufacturers on the market. The editor of 51Dongshi recommends choosing a good aluminum veneer manufacturer. Because better aluminum veneer manufacturers not only have guaranteed product quality, but will also design a set of reasonable plans for customers to choose based on their needs, and also provide thoughtful after-sales services.

Aluminum veneer installation Aluminum veneer curtain wall installation Aluminum veneer curtain wall installation process flow: laying out → fixing the frame connector → fixing the frame → installing aluminum plate → closing structure processing → inspection

1. Laying out: determine the grid according to the design. Determine the baseline according to the grid plan and lay out the lines. Check the quality of the main structure before laying out the wires.

2. Connectors to fix the skeleton: Weld connectors on the columns of the main structure to fix the skeleton.

3. Fixed skeleton: The skeleton is treated with anti-corrosion in advance. The installation frame is in an accurate position and the combination is firm. After installation, check the centerline, surface elevation, etc. In order to ensure the installation accuracy of the board, it is advisable to use theodolite to penetrate the beams and mullion members. Properly handle deformation joints, settlement joints, variable cross-sections, etc. to ensure that they meet usage requirements.

4. Installation of aluminum plates: The installation and fixation of aluminum plates must be firm, reliable, and simple.

5. Closing structure processing: The gap between the boards must be internally processed to make it flat and smooth. After the aluminum plate is installed, cover and protect the parts easily contaminated with plastic film or other materials.

6. Inspection: The overall surface is smooth, clean, and consistent in color; there must be no obvious depressions within 5_; the installation is firm and the glue joints are tight; the board joints are straight and required to be on the same horizontal/vertical line. Details>>

Aluminum veneer ceiling installation 1. Construction preparation: First determine the construction site, measure whether the design elevation and the actual elevation are consistent. If the ceiling elevation is affected by other facilities, submit it to the technical person in charge for implementation. . According to the confirmed accurate 1M line, play the determined elevation line on the wall.

2. The boom adopts Ф10 boom, and the boom spacing is 800-1000mm. The expansion bolts that fix the boom should be fully tightened and cannot be loosened. The distance between the boom and the end of the main keel shall not be greater than 300mm. When it is greater than 300mm, a boom should be added. When the boom meets the equipment, the boom should be adjusted and added. Since the length of the boom exceeds 1500mm, a counter support or conversion layer is required before installing the keel.

3. Before installing the keel, the net height of the room, the elevation of the opening, and the elevation of the pipes, equipment and brackets in the ceiling should be handover inspected according to the design requirements. And by familiarizing themselves with the drawings and communicating with all parties, we can grasp the specific locations of lamps, evacuation speakers, air conditioning outlets (returns), sprinklers, and fire probes on the ceiling, so that the main keel can be avoided as much as possible when hoisting.

4. Heavy lamps and other heavy equipment are strictly prohibited from being installed on the keels of suspended ceiling projects.

5. When installing the corner keels, the arch should be raised, generally 1/200 of the short span (the center of the horizontal line within the 10m span is raised 1 cm higher), and the first corner keel on the wall should be away from the edge of the wall ≤200mm (one more should be added when the final distance from the wall exceeds 200mm). The joints should be staggered and cannot be in a straight line with the adjacent keel joints. The direction of the suspender should also be staggered to prevent the corner keel from tipping to one side.

6. After installing the corner keels, determine the distance between the J-groove keels according to the width of the aluminum veneer, and use Ф6*16 galvanized steel screws to fix the J-groove keels to the corner keels.

7. Install the L-shaped aluminum corners and fix them with the wall with plastic expansion tube self-tapping screws, with a fixed distance of 300MM.

8. Install decorative panels: Before installing decorative panels, the debugging and acceptance of pipelines and equipment in the ceiling should be completed, and concealed acceptance procedures should be completed. The decorative panel and the keel should be tightly connected, and the plane should be flat without any unevenness or warping. Details>>

Aluminum veneer cleaning and maintenance Aluminum veneer cleaning:

Cleaning of exterior wall aluminum veneers and glass requires working outdoors and at high altitudes, so you must find professionals and Use hanging baskets, hanging boards, lifting platforms and other transportation tools. The cleaning method is to first rinse the surface of the aluminum plate with a large amount of water, then gently wipe the surface of the aluminum plate with a soft cloth soaked in water-diluted detergent, and then rinse the surface with a large amount of water to wash away the dirt. Then check the board surface, clean the areas that are not clean with detergent, and then rinse the board surface with clean water until all the detergent is washed away.

Aluminum veneer maintenance:

The maintenance of aluminum veneer curtain wall is mainly to check the sealing condition between the panels. The sealing between boards mainly relies on sealing strips and glass glue. If any falls off, it must be repaired and replaced in time. When repairing or replacing, do not step on the aluminum or pull on the frame for support. This is easy to wear the aluminum veneer curtain wall or cause accidents. Always check the joint between the frame and the wall. If the screws at the joint are found to be loose, tighten them immediately. If the screw footing is loose, use epoxy strong glue mixed with a small amount of cement to seal it.
