1. Aluminum panel has the characteristics of light weight, good rigidity, high strength, 3 mm thick aluminum panel weight 8kg per square panel, tensile strength 1-28N /mm2 2. Aluminum panel has good weather resistance and corrosion resistance. PVDF Cocoa Fluorocarbon lacquer with KYNAR-5 and HYLUR5 as the base material made the surface of aluminum panels colorfast for 5 years. 3. Good performance. The aluminum panel can be processed into complex geometrical shapes such as plane, arc and sphere by using the process of first processing and then painting. 4. Aluminum panel coating is uniform and colorful. Electrostatic spraying technology makes paint and aluminum panel adhesion uniform, color diversity, large choice space. 5. Aluminum panel is not easy to stain, easy to clean and maintain. Fluorine coating film of non-adhesion, so that the surface is difficult to adhere to pollutants, more good self-cleaning. 6. The construction is convenient and fast. Aluminum panel forming in the factory, the construction site without cutting, fixed on the skeleton can be. 7. The aluminum panele can be recycled, conducive to environmental protection. Aluminum panel can be recycled 1%, different from glass, stone, ceramic, aluminum panel and other decorative materials, recycling residual value is high. Application: 1. External wall, beams and columns, balconies 2. Building conference hall, opera house 3. Venues 4. The lobby and so on.
The spraying of PVDF aluminum panel six major processes
1. Purpose of pre-treatment: before spraying aluminum panel and sheet, the surface of the workpiece should be deoiled, decontaminated and chemically treated to produce chromified film, increase the binding force between coating and metal surface and anti-oxidation ability, which is conducive to prolonging the service life of paint film.
2. Primer coating: as a primer coating for sealing substrates, its role is to improve the anti-penetration ability of the coating, enhance the protection of the substrate, stabilize the metal surface layer, strengthen the adhesion of the paint and metal surface, can ensure the color uniformity of the paint coating, the thickness of the paint layer is generally 5-10 microns.
3. Topcoat coating: Topcoat coating is the key layer of spraying layer, is to provide the decorative color needed for aluminum, so that the appearance of aluminum to meet the design requirements, and protect the metal surface from the outside environment atmosphere, acid rain, pollution erosion, to prevent UV penetration. Greatly enhance the anti-aging ability, top paint coating is the thickest layer of paint coating in spraying, paint layer thickness is generally 23-30 microns.
4. Glowing lacquer coating: Glowing lacquer coating is also known as varnish coating, the main purpose is to more effectively enhance the anti erosion ability of the paint layer, protect the finish coating, increase the metallic luster of the finish color, the appearance of more bright color, dazzling, coating thickness is generally 5-10 microns. The total thickness of the three spraying layers is generally 40-60 microns, which can be thickened for special needs.
5. Curing treatment: three spraying layer generally need two curing, aluminum into the curing furnace treatment, curing temperature is generally between 180℃-250℃, curing time for 15-25 minutes, different fluorocarbon-coating manufacturers, will according to their own coating, to provide the best temperature and time. Chlorine carbon spraying factory (curium oil plant) also some according to their own experience to three spray when the two curing instead of a cure.
6. Quality inspection: Quality inspection shall be in accordance with AAMA-605.02.90 standard. Strict quality inspection can ensure high quality spraying products.
