The coating types of color coated plate can be divided into: polyester, silicon modified polyester, vinylidene fluoride, plastic sol.
Coating production process in the world, the production process of color coating plate mainly includes roll coating, electrostatic powder coating and screen flow. At present, roller coating is a mature and widely used production process for color coated
The liquid coating is applied to the upper and lower surface of the strip steel by the roller coating machine, and the product production is completed after baking, curing and cooling. The number of units adopting this production process
is the largest, and the units can be produced in high-speed and mass production. The products can be used in construction, home appliances, automobiles and other industries, and can be carried out on the same unit with the film coating. Roller coater
is one of the main factors that affect roller coater production.
When the roller coater is configured, the coating quality should be considered first. The roller coater must be reliable and can produce stable coating surface. The wet film thickness
which can be controlled by the roller coater itself is a main index (the dry film thickness depends on the proportion of solidified substance in the coating). Accurate control of coating thickness is not only the premise to ensure a good coating surface,
but also to reduce paint consumption and production cost.
