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