CEF extrusion film has gel particles
Sorun Belirtisi
Transparent gel particles of 0.1-0.5mm appear on the surface of the CEF extruded film
Neden Analizi
The high-molecular-weight components in CEF are not fully melted during extrusion, forming local high-crystallization areas; the extrusion temperature is low or the mixing is insufficient
Çözüm
1) Increase the extrusion temperature by 5-10°C to ensure full melting; 2) Increase the length of the screw mixing section; 3) Inspect the raw materials to ensure consistent grades; 4) Replace with a finer screen 120 mesh to intercept unmelted particles
Temel Çıkarım
Gel particles are caused by insufficient melting; increasing the temperature and mixing are the key
