PPSU oven drying
Problem Phenomenon
PPSU air circulation oven drying; uniformity and efficiency.
Cause Analysis
PPSU air circulation oven or dehumidifying hopper drying; oven uniformity; material layer thickness; time and temperature; energy efficiency.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Oven uniformity management; ②material layer thickness control; ③time and temperature specification; ④energy optimization; ⑤effect verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPSU oven drying is a standard method; uniformity is the key to quality; specification ensures effect.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
