As a new type of building material, wood grain aluminum veneer is a good alternative material. The degree of imitation of wood grain is extremely high. With the promotion and popularization of the concept of environmental protection, various curtain wall decoration materials have entered the market one after another. Wood grain aluminum veneer has greater advantages than traditional curtain wall decoration materials.
This article mainly introduces wood grain aluminum veneer, one of the types of aluminum panels.

1. Introduction of Wood Grain Aluminum panel
Wood grain transfer aluminum panel is a decorative material that uses high-grade aluminum alloy as the main material. On the basis of electrostatic powder spraying, the wood grain pattern is quickly transferred and penetrated into the aluminum material through the transfer process. The wood grain transfer aluminum panel has a better simulation effect and can be used in place of wood in special parts. Its size, shape and bending degree can be customized according to the design and use requirements, and it is a common material for indoor and outdoor decoration.

2. Types of Wood Grain Aluminum panel Processing Technology
The processing technology of wood grain transfer aluminum panel is commonly divided into three types: thermal transfer, watermark transfer and water drape transfer.
Thermal Transfer
The principle of wood grain thermal transfer printing process is to transfer the wood grain pattern on the film to the surface of the aluminum panel sprayed with electrostatic powder by heating the thermal transfer film to form a decorative film.
The thermal transfer process is also divided into two production processes: gluing and thermal transfer.
Gluing is to paste the transfer paper with wood grain on the aluminum panel with special glue, and then bake the aluminum panel at high temperature. After a certain period of time, the required pattern will be displayed on the aluminum panel.
Thermal transfer printing is to press the paper on the aluminum panel through high-pressure equipment, and bake it at high temperature, so that the pattern is displayed and the quality of the wood grain is better. As it is more complicated than that of gluing, and more processes are used, the price of panel using thermal transfer printing will be higher than that of gluing.

Watermark Transfer
The watermark transfer process can completely transfer the graphics and text on the transfer paper to the surface of the substrate, which is suitable for the transfer of specific patterns, text information, etc..
Compared with the thermal transfer process, the difference is that watermark uses water pressure. Its low investment makes it very popular in the market. The watermark transfer process does not require activator, which avoids the pollution of organic solvents, and has obvious advantages in the production of handicrafts and decorations.
Not only aluminum panel, but also plastics, ceramics, and many other materials can be used as carriers for watermark transfer, and the textures of the transfer are also very diverse.

Water Drape Transfer
Water drape film is printed on the surface of water-soluble polyvinyl alcohol film by traditional gravure printing process. The disadvantage is that during the coating process, the graphics and text are easily deformed due to the large flexibility of the substrate. For this reason, graphics and texts are generally designed as continuous patterns, and even if the transfer is deformed, the decorative effect will not be affected. The gravure water-coating film uses water transfer ink. Compared with traditional ink, water transfer ink has good water resistance, and the drying method is volatilization drying.
In most cases, Alumideas will use the wood grain heat transfer process, not only because of its low cost, but also because the wood grain heat transfer technology is more mature, the quality assurance of wood grain is high, and the printing effect of aluminum panel can be well guaranteed.

3. Process of Wood Grain Heat Transfer Gluing
Premièrement, grind and clean the aluminum panel to ensure that the surface of the aluminum panel is smooth and free of particles, and then spray the primer coating on the surface of the aluminum panel in the process of electrostatic spraying.
Then the aluminum panel is coated with a special glue to fix the wood grain transfer paper. Then wrap the aluminum panel with wood grain transfer paper, and fix the interface of the transfer paper again with high temperature-resistant tape to prevent the paper from loosening in the following steps.
After pasting the wood grain transfer paper, put the aluminum panel into the oven, and use high temperature to transfer the wood grain on the transfer paper to the aluminum panel. The baking temperature and time need to be adjusted according to the texture depth to be transferred on the surface of the aluminum panel.
After the baking is completed, take out the transferred aluminum panel from the oven, and dry the wood grain paper on the layout, so that the wood grain paper is completely stick to the surface of the panel. The grain of the wood grain paper will be transferred to the surface of the aluminum panel. The wood grain color is the color obtained by the interaction between the primer coating and the color transferred from the wood grain paper.
After the transfer is completed, the high temperature resistant tape will be peeled off and the surface of the aluminum panel will be cleaned. Carefully check the wood grain transfer in case of some places are without wood grain or the grain is incomplete. After the inspection is completed, the protective film will be attached to the surface of the aluminum panel.

4. Advantages of Wood Grain Aluminum Veneer
Imitation wood grain aluminum veneer is made of aluminum veneer as a base material, mixed with paints of three or more colors, and painted under certain temperature conditions and manufacturing processes.
Compared with wood panels, wood grain aluminum alloy veneer has the advantages of light weight, environmental protection, durabilité, pollution resistance, nettoyage facile, and convenient transportation.
The wood grain aluminum veneer not only has a beautiful appearance, but also has a rich choice of wood grains and a clear and realistic texture. En même temps, it also has fire resistance, corrosion resistance and moisture resistance that wood does not have.
Entre-temps, the wood grain aluminum veneer also has the characteristics of anti-rust, anti-breakage, anti-ultraviolet and so on. It has strong ductility and can be processed into various complex shapes, and its back can also be filled with insulating materials, sound insulation materials, etc..
The most important point is that the wood grain aluminum veneer can be recycled, which protects the ecological environment, and reduces the waste of material resources.

5. Summary:
This article introduces the process of wood grain aluminum panel and its advantages.
Aluminum veneer not only has common colors, such as white, black, etc., but also has wood grain and stone grain texture. Customers can determine what kind of aluminum veneer through their own design and preferences.
