Aluminum tubes are commonly used in various industries, such as automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, household appliances, etc. Aluminum rods have been ubiquitous in our lives. The aluminum rod factory is extremely rich in metal elements on the earth, and its reserves rank first among metals. It was not until the end of the 19th century that aluminum emerged as a competitive metal in engineering applications, and it became popular for a while. Why aluminum circles are so popular? Today I will bring you an introduction in this regard. And, do you know that it is precise because of its characteristics that determine the usefulness of aluminum circles and rods.
Common nominal processing technology of aluminum tubes: painted products
① According to the coating process, aluminum tubes can be divided into: sprayed plate products and pre-rolled plate;
According to the paint varieties, it can be divided into: polyester, polyurethane, polyamide, modified silicon, epoxy resin, fluorocarbon, etc. According to the different metal elements contained in aluminum tubes, aluminum rods can be roughly divided into 8 categories.
② Among the various coatings, the important functional difference is the ability to resist sunlight and ultraviolet rays. Among them, the most commonly used coating on the front is fluorocarbon paint (PVDF), which has a strong ability to resist ultraviolet rays; the back can choose polyester or ring Oxygen resin coating is used as maintenance paint. In addition, a removable maintenance film can be attached to the front side.
