Powder coated is included in the process of steel pipe legs, hairpin legs and cast iron legs. Today we will come to know the powder coated process.
A surface treatment method that sprays coating powder onto parts. The utility model has the advantages that no thin material is needed, the construction has no pollution to the environment, and is non-toxic to the human body; the appearance quality of the coating is excellent, the adhesion and mechanical strength are strong; the curing time of the spraying construction is short; the corrosion resistance and wear resistance of the coating is much higher, and the bottom is not needed. The paint, the construction is simple, the technical requirements for the workers are low, and the cost is lower than the painting process.
The powder coated is charged by a high-voltage electrostatic device, and under the action of an electric field, the paint is sprayed onto the surface of the workpiece, and the powder is uniformly adsorbed on the surface of the workpiece to form a powder coating; after the powder coating is baked at a high temperature When the leveling is solidified, the plastic particles will melt into a layer of dense final protective coating; the film is firmly attached to the surface of the workpiece, and the sprayed product is mostly used for indoor use, and the paint film has a flat or matte effect. The spray powder mainly includes acrylic powder, polyester powder and the like.
