    Color coated coating types can be divided into: polyester, silicon modified polyester, vinylidene fluoride, plastic sol.
    Coating production process The world's production of color coated plate technology mainly roll coating method, electrostatic powder coating and curtain flow method. Roller coating is currently a production color-coated plate is a more mature and widely used in the production process.
    The liquid coating material is applied to the upper and lower surfaces of the strip steel by a roll coater to be cooled and solidified by baking to complete the production of the product. The production process using the largest number of units, the unit can be high-speed, high-volume production, the product can be used in construction, home appliances and automobiles and other industries, and at the same time with the film coating in the same unit carried out. Roll coater is a major factor affecting roll coating production.
    When configuring a roll coater, consider the coating quality first and roll coaters must be reliable and ensure a stable coating surface. The wet film thickness controlled by the roll coater itself is a key indicator (dry film thickness depends on the proportion of cured material in the coating). Precise control of the coating thickness is not only a prerequisite for ensuring a good coating surface, but it also reduces paint consumption and production costs.
