PVA surface snakeskin pattern
Sorun Belirtisi
PVA extruded product surface has snakeskin-like irregular texture
Neden Analizi
Extrusion temperature on the low side, uneven melt elastic recovery; uneven die temperature distribution
Çözüm
1) Raise extrusion temperature to the processing temperature range; 2) Homogenize die temperature ±2°C; 3) Reduce extrusion rate to reduce elastic recovery
Temel Çıkarım
Snakeskin pattern is caused by low-temperature extrusion and elastic recovery; raising temperature and reducing speed are the key
