PVDF Product Purity Requirements
Problem Phenomenon
Contamination in semiconductor/pharmaceutical high-purity applications.
Cause Analysis
High-purity applications have strict requirements for metal ion leaching and particles; equipment corrosion products are a contamination source.; 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 high-purity grade; ②equipment corrosion resistance to prevent contamination; ③clean production environment; ④test according to industry standards.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
For high-purity PVDF applications, equipment corrosion resistance is a dual need; it prevents both corrosion and contamination.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
