PESU Membrane and Coating
Problem Phenomenon
PESU solution-processed membranes and coatings, separation and protection applications.
Cause Analysis
PESU solution-processed membrane; separation performance; coating protection; uniform thickness; performance testing.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Solution process; ②thickness control; ③performance testing; ④application matching; ⑤quality stability.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PESU membrane and coating are functional applications; process and performance are equally important; testing ensures quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
