The fully automatic spraying line improves the utilization rate of paint in many ways, as follows:

1. Use advanced spraying technology

Electrostatic spraying technology: Electrostatic spraying is to atomize and charge the paint through a high-voltage electrostatic field. The charged paint particles are adsorbed to the grounded workpiece surface under the action of the electric field to form a uniform coating. The advantages of this technology are high paint utilization and stable spraying quality.

High-pressure airless spraying technology: This technology uses a high-pressure airless sprayer to atomize the paint at extremely high pressure and spray it onto the workpiece surface. Due to the less scattering of atomized paint and solvent, environmental pollution and labor conditions are improved, and the paint utilization rate is also high.

Powder spraying technology: Powder spraying technology realizes solvent-free and non-toxic dry coating production, and one coating can achieve the coating thickness of multiple coatings of solvent-based paint. Excess powder coating can be recycled, basically without environmental pollution, and high paint utilization.

2. Optimize spraying parameters

Spraying pressure and flow control: By accurately controlling the spraying pressure and paint flow, paint waste can be reduced.

Adjustment of spray gun parameters: Adjust the spray gun's spray angle, spray distance and paint flow rate to ensure that the paint is evenly covered on the workpiece surface.

3. Efficient recovery system

Powder recovery system: For powder spraying, an efficient powder recovery system can significantly reduce powder waste.

Paint recovery: In the process of spraying certain liquid paints, the paint that is not attached to the workpiece surface can be recycled and reused by designing a reasonable recovery system.

4. Choose the right paint and equipment

High solid content paint: The use of high solid content paint can reduce the volatile organic compound (VOC) content in the paint and improve the spraying efficiency.

Automated equipment: The introduction of automated spraying equipment, such as a robotic spraying system, can achieve efficient and uniform spraying effects and reduce paint waste.

5. Reduce the number of color changes and reworks

Fast color change technology: The use of fast color change technology can reduce paint waste and production interruptions caused by color changes.

Improve product quality: By optimizing the spraying process and equipment parameters, reduce the number of reworks and improve the one-time qualified rate of products.

Through the above measures, the fully automatic spraying line can significantly improve the utilization rate of paint.
