EMA internal unmelted particles
Fenómeno del problema
Unmelted transparent or translucent particles appear inside EMA products
Análisis de la causa
Screw plasticizing capacity insufficient with temperature too low; feeding amount too large exceeding plasticizing capacity; EMA melting temperature too high
Solución
1) Increase processing temperature to ensure full melting; 2) Reduce feeding amount to match plasticizing capacity; 3) Increase screw mixing section
Conclusión clave
Unmelted particles are caused by insufficient plasticization; increasing temperature and reducing feeding are key
