I. The solution of uneven color
1.1 Cause analysis
Uneven color may be caused by uneven distribution of paint pigments or poor adhesion of paint.
1.2 Solution
(1) Adjust the spraying parameters to ensure uniform powder coating.
(2) Appropriately increase the coating thickness to ensure uniform pigment distribution.
(3) Use pigment dispersant to make pigment distribution more uniform.
Second, the solution of insufficient coating thickness
2.1 Cause analysis
Insufficient coating thickness may be caused by insufficient powder spraying amount or too short spraying time.
2.2 Solution
(1) Adjust the spraying parameters to ensure the proper amount of powder coating.
(2) Extend the spraying time to ensure that the coating thickness meets the requirements.
(3) Increase the number of coatings so that the coating thickness meets the requirements.
Third, the solution of low powder recovery rate
3.1 Cause analysis
Low powder recovery rate may be due to the imperfection of the recovery system, unreasonable spraying equipment or improper powder recovery treatment.
3.2 Solution
(1) Improve the recycling system and use efficient recycling equipment.
(2) Use appropriate spraying equipment to ensure uniform powder coating.
(3) Handle the recycled powder correctly to avoid waste.
The above is the solution of common problems of powder coating, hope it can help you. If you have other questions, you can consult professional coating manufacturers or coating application companies.
