PVDF Product Weather Resistance Application
Problem Phenomenon
Long-term outdoor use.
Cause Analysis
PVDF has excellent weather resistance (fluorocarbon coating base material); processing quality affects long-term performance.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Select a weather-resistant grade; ②control processing quality; ③perform aging verification; ④avoid processing degradation.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PVDF weather resistance is top-level; processing protection is the prerequisite for realizing it.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a reference for troubleshooting similar problems in the future
