DSTDP extruded film gel particles
Sorun Belirtisi
DSTDP extruded film surface shows 0.1-0.5mm transparent gel particles
Neden Analizi
High molecular weight components in DSTDP not fully melted during extrusion forming local high-crystallinity regions; extrusion temperature on the low side or mixing insufficient
Çözüm
1) Raise extrusion temperature 5-10°C to ensure full melting; 2) increase screw mixing section length; 3) raw material inspection to ensure grade consistency; 4) replace with a finer screen 120 mesh to intercept unmelted particles
Temel Çıkarım
Gel particles are caused by insufficient melting; raising temperature and mixing are key
