EEA Poor Plasticization
Fenómeno do problema
Unmelted particles appear in EEA products, plasticization incomplete
Análise das causas
Screw compression ratio insufficient <2.5, plasticizing pressure low; screw speed low, shear insufficient; processing temperature low
Solução
1) Select a screw with compression ratio >3; 2) Increase screw speed to increase shear; 3) Increase processing temperature by 5-10°C
Conclusão principal
Poor plasticization is caused by improper screw design; optimizing the screw and raising temperature are key
