1.Standard common aluminum veneer specifications: ① The common specifications of the inner wall aluminum veneer are 1200mm*1800mm,600mm*1200mm.
② The common size of aluminum veneer ceiling is 600mm*600mm, 300mm*300mm and other specifications.
The outer wall aluminum veneer specifications are not fixed, can be processed according to the design size, the width should be given priority to 1.5m and below specifications, the length is not recommended to exceed 6m.
Normal thickness of aluminum veneer:
① Thickness of outdoor aluminum veneer: generally choose 2.5mm,3.0mm.
② Outdoor bottom floor and podium part: generally choose 2.0mm thickness.
③ Indoor wall aluminum veneer or indoor ceiling aluminum veneer: Generally, the thinest thickness is 1.0mm or 1.5mm aluminum sheet. The expansion size within 1300*4000mm is a conventional plate, and beyond that, it is an unconventional plate.
Aluminum veneer width direction: Usually the aluminum veneer raw materials of aluminum plate manufacturers are rolled into the factory, and the common width varies from factory to factory, mostly 1.5m to 2.4m and wider.
The width of aluminum veneer should be given priority to 1.5m and below specifications, because this specification has the lowest price and the shortest supply cycle.
The width of the plate not only increases the price, but also increases the deformation capacity with the increase of the size, which is easy to cause the surface deformation of the workpiece and instability after installation.
Aluminum veneer length direction: Because the length of the general bending equipment is up to 6m, it is not recommended to process aluminum veneer workpiece with a length of more than 6m.
2. The difference between aluminum veneer and aluminum-plastic board
1Different concepts Aluminum veneer refers to the building decoration materials formed by processing after chromization and other treatment, and then using fluorocarbon spraying technology; The aluminum-plastic composite board is composed of multi-layer materials, the upper and lower layers are high-purity aluminum alloy plates, the middle is non-toxic low-density polyethylene (PE) core board, and the front side is also pasted with a protective film.
2 the number of layers is different When we study aluminum veneer and aluminum-plastic board, we can look at its number of layers.
If it is two layers, it is aluminum veneer, the first layer is made of aluminum skin, and the second layer is generally plastic. However, the aluminum-plastic board has one more layer, because its first layer and third layer are made of aluminum skin, but the middle is plastic, so it is obvious that there is one more layer.
3, processing process different aluminum veneer in the factory processing, according to the ceiling, column, wall partition size and shape processing, complete bending forming, welding reinforcement, installation Angle code, chemical cleaning, baking curing and other processes, made of products shipped to the site directly positioning installation; The plasticity of aluminum-plastic board is very strong, if you need to slot, you can choose aluminum-plastic board, aluminum-plastic board in the field to cut, bend, paste reinforcement, but the loss is large.
4, the quality of different quality is different, it is because the aluminum-plastic plate than the aluminum veneer more than a layer of aluminum skin, so its resistance is better, the quality is more prominent;
Compared with the two, the service life of aluminum-plastic board is short, and the service life of fluorocarbon sprayed aluminum board is more than 20 years.
5, the price of different prices are different, simply compare the price of the material itself, the same specification, thickness of aluminum veneer is much more expensive than aluminum-plastic board.
6, fire performance aluminum veneer has a certain thickness, itself does not burn, can meet the fire prevention requirements of high-rise buildings;
Early aluminum-plastic plate surface aluminum plate is thin, flammable in case of fire, PE sandwich burning will release toxic gas, now with the development of aluminum-plastic plate technology, now the production of fireproof aluminum-plastic composite board due to the addition of non-toxic flame retardant materials in its PE, fire performance is greatly improved, has been fully able to meet the needs of engineering fire protection.
7, the design structure of aluminum veneer can be welded, so it can be suitable for a variety of building forms, easy to reflect the design creativity, not limited by multidimensional modeling, the bottom bracket using metal can increase strength; Aluminum-plastic plates can only ensure two-dimensional deformation processing, and circular curved edges can not be completed.
