Color coated aluminum coil is the raw material aluminum plate or aluminum coil coated coloring treatment, according to its coating of different types of products, stable performance, long service life, the following we through its production process and use range to understand in detail.

First, the process as follows:

Color coated aluminum coil is after cleaning, chrome, roller coating, baking and other processing, so that the surface of the aluminum coil with a variety of colors of paint coating.

1. Cleaning and pretreatment The pretreatment of aluminum coils is more effective than traditional methods, and water can be reused to reduce energy consumption through repeated cleaning of water flow sprays. The pretreatment phase 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, effective process technology to improve product quality and reduce waste of resources.

2. Coil Coatings Color coated aluminum coil coating process is mainly divided into two stages, respectively, called bottom coating and surface coating. In one stage, the aluminum coil passes through the roller coating machine, its single or double-sided coated with primer.

After drying, the aluminum roll passes through two rollers, at which point the aluminum roll is coated on one or both sides of the coat.

3. Curing Aluminium belt through the curing furnace, the temperature is set at a well-adjusted temperature to ensure that the volatile objects on the aluminum belt are removed and the paint is completely cured. According to the needs of the coating system, the curing temperature is set at 200-300 degrees Celsius, which is the key technical point to ensure the quality of the product.

In addition, in order to protect the environment and control costs, the solvent fog is evaporated by high temperature to heat the curing furnace.

4. Follow-up processing

Coated aluminum rolls can be deeply processed into other appearance: reel, stripe or pressurized pattern, etc.
