electrostatic spraying electrostatic spraying is solid powder coating instead of solvent-based liquid coatings, powder coatings by high voltage to the negatively charged by means of electrostatic attraction adsorbed grounded the method of the surface to be coated, heated and melted (or cured) after coating is obtained.
electrostatic spray is a new process, the liquid component solvent-free powder coatings and dispersion medium used, no dilution and adjust the viscosity when used by itself can not flow to the flow of molten, liquid coating did not like sticking to surface. Thus, the electrostatic spray coating with high efficiency, high performance coating, solvent evaporation, little environmental pollution, energy consumption provinces, the process is simple, short production cycle, low cost of painting, painting is easy to implement automation features. Electrostatic spraying powder coating spray called. The principle: The use of corona discharge phenomena powder coating adsorbed on the workpiece. The process is: the powder coating powder from the supply system by means of compressed gas into the gun, the gun front end of a high voltage high-voltage electrostatic generator, corona discharge, resulting in a dense charge in the vicinity of the powder discharged from the muzzle when the formation of charged paint particles, it is subject to static electricity effect, is attracted to their polar opposite of the work up, with the increase of powder sprayed on, the more charge accumulation, when it reaches a certain thickness, due to the electrostatic repulsion , it will not continue adsorption, so that the entire workpiece to obtain a powder coating certain thickness, and then through the high temperature molten powder, leveling, curing, that is a hard film-forming surface of the workpiece.
electrostatic spray with conventional plating zinc process compared
1, galvanized corrosion bag and spray corrosion bag filter bag life expectancy.
2, excellent coating appearance quality, strong adhesion and mechanical strength.
4, corrosion resistant coating is much higher temperature capabilities.
6, the construction is simple.
7, some occasions been clearly put forward the construction must be used electrostatic spray treatment process.
electrostatic spray process flow:
1, pre-treatment (degreasing, rust, phosphate).
2, electrostatic spraying. (The company uses polyester powder)
3, high temperature curing (typically 180 to 260 degrees).
4, baked cooled. You may care about
