PCL extrusion pelletizing
Problem Phenomenon
PCL extrusion pelletizing quality, degradation and uniformity control.
Cause Analysis
PCL extrusion pelletizing temperature; shear degradation; pellet uniformity; impurity control; drying and storage.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Temperature optimization; ②Shear control; ③Pellet screening; ④Clean production; ⑤Sealed storage.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PCL pelletizing quality affects subsequent processing; temperature and shear management; cleanliness and storage prevent deterioration.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
