Epoxy Coated Gold Aluminum coils for heat exchanger fins

Epoxy coated gold aluminum coils for heat exchanger fins is mainly used in heat exchanger fins. Production process introduction: epoxy coated gold aluminum coils for heat exchanger fins refers to an aluminum coil product with epoxy coating effect on the surface of aluminum coil, which can also be called color coated aluminum coil and color aluminum coil. The purpose of coating treatment is to be used on the fin of heat exchanger for a longer time.
Coating process is a key step in the production of epoxy coated gold aluminum coats for heat exchanger fins, 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. What is the specific process of epoxy coated gold aluminum coils for heat exchanger fins?
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.
Aluminum coil
1、 The raw material 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.
