CEF plasticization poor
Problem Phenomenon
Unmelted particles appear in the CEF product, the plasticization is incomplete
Cause Analysis
The screw compression ratio is insufficient <2.5 and the plasticizing pressure is low; the screw speed is low and the shearing is insufficient; the processing temperature is low
Solution
1) Select a screw with a compression ratio >3; 2) Increase the screw speed to increase the shearing; 3) Increase the processing temperature by 5-10°C
Key Takeaway
Poor plasticization is caused by improper screw design; optimizing the screw and increasing the temperature are the key
