Correct Usage
Before commencing any powder - coating operations, it is essential to conduct a thorough pre - start inspection. Ensure that the electrostatic charging system is properly calibrated and functioning optimally. Check the ventilation system to ensure that the exhaust fans are running smoothly and that the ducts are clear of any blockages.
Securely ground the workpiece to ensure proper electrostatic adhesion. Use a reliable grounding method, such as a grounding cable connected to a grounded metal surface. This will ensure that the charged powder is attracted to the workpiece and adheres evenly.
Based on the type of powder and the material of the workpiece, carefully adjust the electrostatic voltage. Different powders and workpiece materials may require different voltage settings to achieve the optimal coating effect. Consult the powder manufacturer's guidelines and the booth's user manual for recommended voltage settings.
During the spraying process, maintain a consistent distance of approximately 15 - 20 cm between the gun and the workpiece. Move the gun at a steady speed, keeping the spraying pattern uniform. This will help to ensure an even application of the powder and a consistent coating thickness.
After the spraying is complete, allow the ventilation system to run for a few additional minutes to clear any remaining powder particles from the air. Then, clean the booth and the powder - reclaim system thoroughly. Use a soft - bristle brush or compressed air to remove any powder residue from the booth's interior, the electrostatic charging components, and the powder - reclaim units. Regular cleaning is essential to maintain the performance and longevity of the booth.
