Surface Treatment Method
Powder coating is a type of coating that is applied as a free-flowing, dry powder, which is then heated to form a skin. Uniformly, evenly spraying powder coating on the surface of the workpiece and baking it at high temperatures, the protective film formed on the surface is uniform and smooth.
Galvanizing is a protective treatment for metal, where a steel or iron object is coated with a layer of zinc metal, which acts as a barrier to protect the underlying metal. The zinc is then allowed to adhere tightly, forming a uniform, strong and corrosion resistant protective layer by processes like hot-dip or electroplating, resulting in prolonged metal service life.
Spray painting is a type of surface treatment technology used for metals or other materials. It is a process of applying a liquid coating evenly on the surface of material by spray and then it is dried naturally or baked at low temperature, as a result a smooth, uniform and strong protective film is formed which can also be used as color and decoration for the material.
