The Spraying Process Of Aluminum Veneer Is Introduced.

1, electrostatic powder spraying process Electrostatic powder spraying process is aluminum veneer manufacturer is one of the most commonly used process, spraying powder is the first ingredient of polyurethane, epoxy resin particles, the process of strength is very simple to operate, spraying aluminum veneer products through this process, generally has a good wear resistance and corrosion function, but unable to uv radiation, if by ultraviolet light to shine for a long time, The product will have a decolorization situation, so the aluminum veneer products treated with this process are mostly used in indoor scenes. 2, polyester paint spray workers Polyester paint spraying process is also a kind of process, which are frequently used polyester lacquer is more groups of paint, the primary ingredient is polyester resin, this kind of paint is a high quality paint, has a solid coating, and road surface is relatively strong, but also because such a lacquer layer to the effect of aluminum veneer play a maintenance, has the very strong corrosion resistant function, and the color is gorgeous, Mostly used in indoor scenes. 3, fluorocarbon spraying treatment Using carbon coating process of aluminum sheet used in the field more scenario, by coating a first component containing perfluorinated propylene, ptfe such copolymer compound, the coating itself has very good heat resistance, weather resistance, and other functions, can resist the high temperature of two hundred and sixty degrees, spots is not simple, in the harsh environment will not change color and fade, Able to resist ultraviolet rays, aluminum veneers treated with this coating inherit these characteristics, and therefore very suitable for outdoor use.

          The appearance quality of aluminum veneer has the characteristics of corrosion resistance and weather resistance, so that aluminum veneer products can effectively extend the use time. When aluminum veneer material is processed, aluminum veneer manufacturers adopt multi-layer spraying technique for its appearance, so as to better play the role of aluminum veneer material.


         From the perspective of the production process of aluminum veneer, the main steps of multi-layer spraying process are: firstly, the primer coating of aluminum veneer is carried out, then the finish coating is carried out, and finally the corresponding appearance curing effect of aluminum veneer material is processed.


        The first step in aluminum veneer coating is a primer coating, which is a decorative primer closed by aluminum veneer. As an internal decorative process, this layer is mainly used to improve the permeability resistance of the coating during further finishing. The aluminum veneer is protected by an effective undercoat. This can not only stabilize the surface effect of the material, so that the finishing effect has a good uniformity, improve the adhesion of the surface paint material and metal plate. The thickness of the primer should be controlled at 5-10 microns.


       The second step of aluminum veneer coating is the finish coat. Finishing coat is the spraying of corresponding color on the surface of aluminum veneer, which is an important step for decoration.

The finish coat is a direct finish on top of the aluminum veneer material and is operated according to the design requirements. Finish coating can be added to effectively decorate the appearance and beautify the aluminum veneer material, making it more suitable for the needs of architectural decoration.

At the same time, aluminum veneer material can avoid direct contact with the external air, so that it is not subjected to acid rain, pollutants, etc., to delay the aging of the material. The thickness of the general topcoat should be controlled in 20-30 micron.


        The third step of aluminum veneer coating is the finish coating treatment. Varnish coating is also what we often say varnish coating. The main reason for varnish treatment is to increase the anti-invasion ability of the coating to the external environment, better protect the integrity of the finish coat, enhance the gloss effect on the surface, and maintain the bright color. The thickness of varnish coating is generally required to be about 5-10 microns.


       The final step of aluminum veneer spraying is the solidification treatment as a consolidation effect, that is, the further consolidation of the three layers of coating, so that it has a better decorative effect.

This step requires the aluminum alloy to be kept in a curing furnace for high temperature consolidation at a temperature between 180 and 250 degrees Celsius. Of course, different aluminum veneer manufacturers will be based on their own production of materials and other conditions to control the temperature and length of certain.
