PESU Drying in High-Humidity Weather
Problem Phenomenon
PESU drying time extended in high-humidity weather, environmental compensation management.
Cause Analysis
PESU resin drying time needs to increase in high-humidity weather; environmental humidity influence; drying efficiency; quality risk; adjustment specifications.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Extend drying in high-humidity weather; ②environmental humidity monitoring; ③drying verification; ④specification adjustment.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PESU environmental humidity management is a quality detail; compensation adjustment prevents risk; verification ensures compliance.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
