Aluminum veneer after sheet metal processing molding, to the spraying workshop. The spraying workshop receives the next day's work instruction one day before production, and finds the corresponding next day's work all paints and the quantity confirmation in the paint warehouse. Go to work in the morning, turn on the power supply of equipment, and start the surface cleaning and chromatization of the pendant according to the work instruction sheet. Count the number of personnel and divide them into engineering categories. After hanging into the spray cleaning process, cleaning is divided into degreasing, pure water cleaning, pickling, pure cleaning, collation, pure water washing. After cleaning the aluminum veneer into the next process, the wind blowing dry, into the drying box, drying box out after air cooling. Aluminum veneer after cooling chain transfer some distance into the paint room, good in primer spray primer inflow flat last in the room, go after a distance into the paint spray, spray well inflow flat surface paint last in the room, on the flow flat chamber after gone some distance to cover the light paint room, spray flow flat after good on the surface of the paint coat, walked a distance after aluminum veneer into the oven, The temperature in the oven is from the bottom to the top to the bottom. After 20 to 25 minutes of baking, the aluminum veneer slowly rotates out of the chain, enters the cooling area, and moves to the next part area. After the next part of the aluminum veneer enters the packaging area, and then puts it into the finished product area, waiting for delivery.
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.
The above is the spraying technological process of aluminum veneer, finishing the production of multilayer coating of aluminum veneer material.
