Glass Fibre extruded film has gel particles
Fenómeno do problema
Glass Fibre extruded film surface shows 0.1-0.5mm transparent gel particles
Análise das causas
High molecular weight component in Glass Fibre not fully melted during extrusion, forming local high-crystallinity regions; extrusion temperature too low or mixing insufficient
Solução
1) Raise extrusion temperature 5-10°C to ensure full melting; 2) increase screw mixing section length; 3) inspect raw material to ensure grade consistency; 4) replace with finer screen 120 mesh to intercept unmelted particles
Conclusão principal
Gel particles are caused by insufficient melting; raising temperature and mixing are key
