Good color coated board in use, whether it is to the use effect or service life has a very important correlation, and color coated board can not do without the role of coating, therefore, for the quality of color coated board should also pay attention
to the choice of coating, the following to understand.
Good color coated board should pay attention to the choice of coating
1、 In general, the color coated plate can be selected according to the standard color of the manufacturer, which can reduce the workload in the early stage of production. If a
special color is needed, the coating can be produced only when the sample configuration is carried out in the coating manufacturer and the performance meets the requirements. Therefore, the production time from ordering to color coated plate will be longer.
2、 The higher the value is, the higher the glossiness of the coating surface is measured by 60 degree reflection angle. The medium gloss and sub gloss of coatings used in architecture are between 30-55. This is because the high gloss coating is used
in buildings to reflect sunlight strongly and glare; if it is indoors, it is easy to cause visual fatigue in the light at night.
3、 The coating of color coated board is made of baking synthetic resin coating. When it is used outdoors, due to the
influence of sunlight, temperature and rain, the film will gradually deteriorate. If you carefully observe the surface of the steel plate or touch it with your finger, you can find the existence of white powder. This phenomenon is the pulverization of
the film, which is inevitable.
4、 Different types of coatings should be selected for color coated board, which can delay the time of powdering. In addition, the service life varies in different areas such as coastal areas, industrial areas and rural
areas. In case of corrosion such as powdering and cracking of the coating, repainting shall be carried out to prolong the service life.
