Coated aluminum coil refers to a product with color spraying effect on the surface of aluminum coil, also known as color coated aluminum coil and color coated aluminum coil. The purpose of coating treatment is to have beautiful effect in construction,
decoration, home and other fields; the second is because the coating process and coating thickness are directly related to the product quality and service life of coated aluminum coil.
Coating process is a key step in the production of color aluminum coil, which directly affects the final coating quality and product durability. Therefore, the coating process is very strict. With the continuous improvement of coating equipment and the
development and utilization of new coatings, the production of coated aluminum coil is more mature, and the processing cost is also decreasing. Therefore, coated aluminum coil has obtained rapid development. So what is the specific process of coated aluminum
Generally, the production process of coil coating has five steps: coil input, cleaning and chemical treatment, painting, curing and finished product output. The process layout and equipment composition are different in different situations,
but the basic parts are the same.
1、 The rawmaterial coil input is the continuous uncoiling of Uncoiler to ensure the continuous and stable input of the coil into the production line. Some adopt the cross rotating beam coiler, and some adopt two
sets of alternate uncoilers, in short, it is for timely coil supply;
2、 Surface cleaning and chemical treatment means that the upper and lower surfaces of aluminum coil must be cleaned, and chemical pretreatment shall be carried
out to ensure that the paint can adhere firmly;
3、 It is painting. There are at least two roller coating machines in one production line to ensure two layers of finish and primer;
4、 It refers to the curing of the paint layer, which means
that the tape coil that has just been painted should be fixed before contacting the next roll surface, so as to avoid adhesion and damage to each other. Generally speaking, it contains at least two curing boxes;
5、 Is the finished product output,
to ensure that the production line speed and finished roll transfer synchronization.
