Aluminium veneer is the application of an external coating or other treatment to the aluminium product to improve its resistance to certain conditions, such as weather or to enhance its beauty. This is especially common in the building and construction industry where such veneer is referred to as anodising.
Fluorocarbon decorative coating technology mainly refers to the polyvinylidene fluoride resin (KANAR500), sub-primer, paint, varnish of three kinds. The spray coating process is generally divided into two, three or four levels. Fluorocarbon coating has excellent corrosion and weather resistance, is also resistant to acid rain, salt spray and a variety of air pollutants. It has excellent thermal performance and can withstand intense UV irradiation, defies fading, will not oxidise or not powder and is long lasting.
Globally there are two kinds of aluminium veneer fluorocarbon spray coating and roll. In the spraying process aluminium veneer production is divided into two steps: The first step is sheet metal processing. This process is mainly through the plates after the cutting, folding, bending, welding, and grinding processes. The aluminium veneer is next processed into the desired shape and size of the construction.
The second step is spraying. Spraying is divided into two stages, one is the artificial spray, the one is a spray machine. Spraying machines are generally only suitable for flat beds, but if the aluminium veneer is to be applied in small areas artificial spraying is the procedure most domestic manufacturers adopt. Manual spraying is a dangerous job, because of the paint volatility and toxicity which when combined is likely to cause chronic benzene poisoning, seriously affecting people's health. The processing of aluminium plate veneer is more complex, there is a major formation, coating, composite and trimming four step process.
