(1) A coating with a thickness of 100-300 μm can be obtained by powder coating once, while it takes 4-8 times of construction to use ordinary coatings, which improves the construction efficiency and shortens the production cycle.
(2) There is no solvent in the coating, no need to dilute and adjust the viscosity, which improves the working conditions and reduces the risk of fire, which is conducive to protecting the environment.
(3) The adhesion and compactness of the coating are improved, and the metal powder, ceramic powder, etc. are mixed together for coating, which can improve the mechanical and physical properties of the coating, and the corrosion resistance of the coating film is greatly improved.
(4) The degree of mechanization is high, and the excess paint can be recycled, which reduces the consumption of paint. (5) The coating equipment is complex, the investment cost is high, the appearance and leveling of the coating are not as good as the spraying method, and some powder coating methods have requirements on the shape and size of the workpiece. It can only be applied to powder coatings, and the cost is high.
