Production process and application of color coated aluminum coil

The color coated aluminum coil is coated and colored on the raw material aluminum plate or aluminum coil. According to the different coatings, there are many kinds of products, the performance is stable and the service life is long. Below we use its production process and scope of use. Learn more about it.
First, the process
The color coated aluminum coil is processed by washing, chromizing, rolling, baking, etc., so that the surface of the aluminum coil is coated with paint of various colors.
1, cleaning and pretreatment
The pretreatment of the aluminum coil is repeated by the water jet spray. This method is more effective than the conventional method, and the water can be reused to reduce the energy consumption. A pretreatment stage is necessary to improve the corrosion resistance of the product and to improve the adhesion of the coating. At this stage, the conversion film is chemically formed on the aluminum surface, and effective process technology improves product quality and reduces resource waste.



2, coil coating
The color coating aluminum coil coating process is mainly divided into two stages, namely, primer coating and top coating. In one stage, the aluminum coil passes through a roll coater and is coated on one or both sides with a primer. After drying, the aluminum coil is passed through two roll coaters, at which time the aluminum roll is coated on one or both sides.
3, curing
The aluminum strip is passed through a curing oven and the temperature is set at a regulated temperature to ensure that the volatiles on the ribbon are removed and the coating is fully cured. According to the needs of the coating system, the curing temperature is set between 200 and 300 degrees Celsius, which is the key technical point to ensure product quality. In addition, in order to protect the environment and control costs, the mist of the solvent is evaporated by high temperature to heat the curing oven.
4, follow-up processing
The coated aluminum coil can be further processed into other shapes: rolling shutters, slitting or compression pattern.
Second, the scope of use
Architectural aspects (aluminum composite panel, aluminum honeycomb, roof wave board, fire veneer panel, aluminum ceiling, shutters, rolling door, garage door, awning, drooping gutter), electronic appliances (computer case, electrical panel), lighting, furniture, solar energy Reflector, air conditioning ducts, etc.
