EMA Extruded Film Has Gel Particles
Sorun Belirtisi
0.1-0.5mm transparent gel particles appear on the surface of EMA extruded film
Neden Analizi
High-molecular-weight components in EMA are not fully melted during extrusion, forming local high-crystallinity zones; extrusion temperature low or mixing insufficient
Çözüm
1) Increase extrusion temperature by 5-10°C to ensure full melting; 2) Increase screw mixing section length; 3) Inspect raw material to ensure consistent grade; 4) Replace with a finer 120-mesh screen to intercept unmelted particles
Temel Çıkarım
Gel particles are caused by insufficient melting; increasing temperature and mixing are key
