Color-coated sheet is an often contact us in a variety of construction and industrial production are relatively common, in general, the use of color-coated, in use, will face the loss of their coating changes the optical properties, for Such a change, color-coated factory experts tested, and finally come up with its rule changes, the following, we will follow together caitu manufacturers to understand the next bar. Caitu manufacturers, experts say, in theory, color-coated optical loss test point should be the worst performance in Hainan, Hainan since the maximum intensity of ultraviolet radiation, radiation longest time, it will destroy the coating structure, resulting in degradation of the resin, the coating surface becomes rough, shiny fastest decline. But the actual test result is loss of light performance Baosteel test points are also poor. Analysts believe Baosteel pilot sites located in an industrial environment, the settlement of various industrial pollutants great, but different from the general industrial fallout dust, it has strong corrosion, the coating of color-coated strong Embeddabilty , can not be removed by the cleaning process, resulting in decreased gloss coating. Meanwhile, the industrial fallout are generally corrosive, corrosive coating embedded in the coating resin structure damage, it can also cause decreased gloss. Within three years of the test period, the impact is even greater than the ultraviolet degradation of the coating. The above is a color coated color coated coating manufacturers to bring you the loss of light performance variation, hoping to give us some help. To learn more about caitu knowledge, please pay attention to us.
