1. What is powder coating?
– Electrostatic powder coating technology is known in English as Electrostatic Powder Coating. It appeared since 1950 and was invented by Dr. Erwin Gemmer after going through much research.
– Powder coating is applied in the form of a heated dry powder, also known as thermoplastic. Powder coating uses an electrostatic charge method for powder coating to create a stable bond with the parts to be coated. According to the principle that the current carrying a positive charge (+) will always be closely associated with a negative charge (-). That’s why the powder coating provides a uniform quality and adheres firmly to the surface.
2. Principle of operation of powder coating
Powder coating works on the principle of creating a coating on the surface of the material using a spray gun. Spray the charged coating on the surface of the material and then heat it. At this time, the paint powder will flow out and adhere to the surface layer of the material, creating a strong bond.
Equipment used in powder coating technology includes spray guns and automatic line systems. In addition, to ensure the principle and process of electrostatic painting, it is also necessary to invest in more spray booths, paint recovery rooms, steam chambers, drying chambers, air compressors, moisture separators and chemical tanks for treatment. Surface treatment of materials before painting.
