PPSU hydrolysis resistance
Problem Phenomenon
PPSU excellent hydrolysis resistance; high-temperature high-humidity application advantage.
Cause Analysis
PPSU hydrolysis resistance; high-temperature high-humidity environment; medical steam; long-term performance; verification data.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①High-temperature high-humidity applications; ②performance verification; ③long-term tracking; ④data accumulation.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
PPSU hydrolysis resistance is the basis of medical and food applications; verification ensures reliability; data supports promotion.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
