Process flow: workpiece grinding pretreatment - hanging workpiece - powder coating - out of the powder coating room into the curing furnace - curing completed - cooling and removing the workpiece.

Advertising Industry

Electrostatic powder coating line is an advanced surface treatment technology, which is widely used in the production process of logo production, display equipment, billboards and other products in the advertising industry.

The electrostatic powder coating line charges powder with a high-voltage static generator, which is then sprayed onto grounded workpieces using a spray gun. Static electricity evenly attracts the powder to form a uniform coating on the workpiece surface.

Components

Pretreatment system

The workpiece needs to be cleaned, degreased, and derusted before painting to ensure good adhesion between the coating and the workpiece surface.

Spraying equipment

The pretreated workpiece is sprayed with powder coating through an electrostatic spray gun.

Baking and curing equipment

The sprayed workpiece is sent to a baking furnace, where the powder coating is melted and cured by high-temperature baking to form a tough protective layer.

Post-processing system

The cured workpiece undergoes subsequent steps such as cooling, inspection, and packaging to ensure product quality.

Features

Scope of application

1. Why is the coating not shiny enough?

Reasons: The baking time is too long, the temperature is too high, other harmful gases are mixed in the baking, the workpiece surface is too rough, and the pre-treatment method is not selected properly. Solutions: Adjust the baking time and temperature, ensure the baking environment is clean, and select the appropriate pre-treatment method
2. Why does the coating change color?

Reasons: Repeated baking, other gases are mixed in the oven, and the baking is excessive during curing.
Solutions: Optimize baking conditions, purify the baking oven, and strengthen cleaning before construction
3. Why is the coating surface orange peel?

Reasons: The thickness of the sprayed coating is uneven, the powder atomization is not good, the spray gun has powder accumulation, the curing temperature is low, the powder is damp, the workpiece grounding is poor, the baking temperature is too high, the workpiece itself has material problems, and the pre-treatment is not handled well.
Solutions: Adjust the distance and angle of the spray gun to ensure uniform powder atomization, control the curing temperature and coating thickness, adjust the workpiece material, and adjust the pre-treatment method.
4. Concave holes appear in the coating?

Reasons: improper treatment, incomplete degreasing, contaminated source, incomplete degreasing and dewatering of compressed air, uneven surface of workpiece, contaminated by dust or other impurities.
Solution: Strengthen pre-treatment, ensure that the compressed air is clean, and clean the surface of the workpiece
5. Why do bubbles appear in the coating?

Reasons: The moisture is not completely dried after the surface treatment of the workpiece, the degreasing and rust removal is not thorough, the bottom volatiles are not removed, there are pores on the surface of the workpiece, and the powder coating is too thick.
Solution: Thoroughly dry the surface of the workpiece, ensure thorough degreasing and rust removal, and control the thickness of the powder coating.
6. Why is the coating uneven?

Reasons: Uneven powder spraying, too close distance between the spray gun and the workpiece, and unstable high-voltage output.
Solution: Adjust the distance and angle of the spray gun to stabilize the high-voltage output
7. Why is the impact strength and adhesion of the coating poor?

Reasons: The phosphate film is too thick, the curing temperature is too low, the time is too short, and the base metal is not cleaned.
‌Solution‌: Control the thickness of the phosphating film, adjust the curing temperature and time, and ensure that the base metal is cleanly processed.
8. Why does the coating produce pinholes?

‌Reason‌: Foreign matter in the air, too high spray gun voltage, too close distance between the spray gun and the workpiece, too thin coating, and insufficient curing of the coating.
‌Solution‌: Clear foreign matter in the air, adjust the spray gun voltage and distance, and ensure that the coating is fully cured.
9. Why does a small amount of sand appear on the surface of the coating?

‌Reason‌: Spray blockage or poor airflow, poor spray gun atomization, powder dripping in the powder spraying room, and other debris contaminating the workpiece surface.
‌Solution‌: Clean the spray system, purify the powder spraying room, and avoid debris contamination.
10. Why does the coating fall off?

‌Reason‌: The surface treatment of the workpiece is not good, the degreasing and rust removal is not thorough, the output voltage of the high-voltage electrostatic generator is insufficient, and the workpiece grounding is poor.
‌Solution‌: Strengthen the surface treatment of the workpiece, ensure thorough degreasing and rust removal, check the output voltage of the electrostatic generator, and ensure that the workpiece is well grounded.
11. Why is the powder supply uneven?

‌Reason: The powder supply pipe or powder spray pipe is blocked, the air pressure is insufficient or unstable, the air compressor is mixed with oil or water, and the powder feeder fluidization is unstable.
‌Solution: Clean the powder supply pipe and powder spray pipe, ensure the air pressure is stable, check the air compressor, and adjust the powder feeder fluidization.
12. Why is the powder flying and the adsorption poor?

‌Reason: The electrostatic generator has insufficient high voltage, the workpiece is poorly grounded, and the air pressure is too high.
‌Solution: Check the output voltage of the electrostatic generator, ensure that the workpiece is well grounded, and adjust the air pressure.
13. Why is the powder spraying amount small?

‌Reason: Insufficient air pressure, insufficient air volume, too high air pressure, water vapor and oil mixed in the air.
‌Solution: Adjust the air pressure, ensure sufficient air volume, and clean the water vapor and oil in the air.
14. Why is the powder spraying pipe blocked?

‌Cause‌: Problem with the material of the powder spraying tube, the powder adheres and hardens at the nozzle, and the air pressure for conveying powder is too low.
‌Solution‌: Replace the material of the powder spraying tube, clean the nozzle regularly, and increase the air pressure for conveying powder.
