What are the specific processes of the coating equipment process?

1. Surface pretreatment of coating equipment. Mainly degreasing and rust removal, stains, the method is the same as the pretreatment of liquid paint.

2. Scrape putty. Conductive putty is scraped according to the degree of workpiece defects, and smoothed with sandpaper after drying.

3. Do a good job of protection. If some parts of the workpiece do not require coating, protective glue can be used to cover it before preheating to avoid spraying paint.

4. Preheat. Generally, no warm-up is required. If a thicker coating is required, the workpiece can be preheated to the appropriate temperature, which can increase the thickness of the coating.

5. Spraying. Under the high-voltage electrostatic field, the powder spray gun is connected to the negative electrode, the workpiece is grounded (positive electrode) to form a loop, and the powder is sprayed by the spray gun with the help of compressed air with negative charge, and it is sprayed onto the workpiece according to the principle of anisotropic attraction to solidify.

6. After spraying, the workpiece is sent to a certain temperature drying room for heating and drying to solidify the powder.

7. Dust removal and cleaning. After the coating has cured, remove the protective material and smooth the burrs.

8. Sanding. Use sandpaper to polish the old paint that needs to be sprayed with intermediate paint, and the middle paint after drying.

9. Inspection of coatings. Check the coating of the workpiece, and all defects such as leakage spray, bumps, needle bubbles, etc., should be reworked and resprayed.

10. Defect Handling. The workpieces detected with defects such as leakage spray, pinholes, bumps, bubbles, etc., are repaired or resprayed until there is no obvious abnormal phenomenon.

Therefore, the painting process of coating equipment affects the painting effect of painting equipment, and spraying according to a certain process flow to achieve quite good results, paying attention to the process flow can produce obvious results.
