Color-coated coils are light, beautiful and have good anti-corrosion properties, and can be directly processed. The colors are generally divided into gray-white, sea blue and brick red. They are mainly used in advertising, construction, household appliances, electrical appliances, furniture and transportation. Industry. The paint used in the color-coated coil selects the appropriate resin according to the use environment.
Such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. Users can choose according to the purpose. Color steel coil is a composite material, also known as color coated steel plate, which is made of strip steel after continuous chemical transfer treatment such as surface degreasing and phosphating on the production line. A product made with an organic coating and baked. Color steel coil is a composite material, which has both advantages of steel plate and organic material. It not only has the mechanical strength and easy forming properties of steel plates, but also has good decorative properties and corrosion resistance of organic materials.
Pretreatment of Color Coated Coil Substrate If the galvanized steel sheet as the substrate is not directly entered into a color coating process after production, rust (white rust), dust, and other contamination may occur during transportation. If these cannot be removed, it will affect the quality of the color coating. The quality and all physical and chemical properties of the finished color-coated rolls are closely related to the pretreatment.
