We usually say that the color coated aluminum coil is a coating treatment of the raw material aluminum coil, stable performance, not easy to be corroded, long service life, widely used in various industries, is a popular new building materials. The following Xiaobian will explain to you the production process of color coated aluminum coil.
1. After cleaning, chromic, roller coating, baking and other processing, the surface of aluminum roll is coated with various colors of oil paint, that is, color coated aluminum roll.
2. Cleaning and pretreatment
The pre-treated aluminum coil is repeatedly cleaned after the water is sprayed. This method is more efficient than traditional methods, and the water can be reused, thus reducing power consumption. It can improve the corrosion resistance of enterprise products and can improve the cohesiveness of coatings. In this stage, by forming a method on the aluminum surface on the chemical conversion film, an effective technique to improve product quality and reduce waste.
3. Coil coating
The coating process is mainly divided into two stages, respectively called bottom coating and surface coating. In the first stage, the aluminum roll passes through a roller coating machine and one or both sides of it are primed. After DRYING, THE ALUMINUM roll PASSES THROUGH A two-ROLLER COATING machine, at which TIME one OR both sides of the ALUMINUM roll are coated.
4,.Curing, subsequent processing
The strip IS PUT THROUGH a curing FURNACE AT A REGULATED TEMPERATURE TO ENSURE THAT VOLATILES are REMOVED FROM THE STRIP AND THAT THE PAINT IS COMPLETELY 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.
For the processing of coated aluminum coil can be deep processed into other shapes: brake, strip or pressure pattern.
The above is a detailed explanation of the production process of color-coated aluminum coil. When using color-coated aluminum coil in different fields, different coatings and kinds of products can be selected according to different requirements, so that it can play a better role in the field.
