Problem Phenomenon
AEPDS painting adhesion and durability, surface energy and pretreatment.
Cause Analysis
AEPDS painting; surface energy; pretreatment; paint matching; adhesion durability; environmental aging.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Pretreatment process; ②paint matching; ③adhesion test; ④durability verification; ⑤environmental assessment.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Pretreatment is the key for AEPDS painting; matching and testing are both important; verification ensures long-term.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
