PPSU extruded profiles
ظاهرة المشكلة
PPSU extruded profiles have bubbles or streaks; insufficient drying or improper process.
تحليل الأسباب
PPSU extrusion with wet resin causes severe blistering or streaks; moisture content <100ppm requirement is stricter; melt temperature uniform; mold design; cooling control.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
الحل
①Extrusion drying <100ppm; ②uniform melt temperature; ③mold temperature management; ④cooling optimization; ⑤online inspection.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
The 100ppm of PPSU extrusion is a stricter standard; uniformity management runs throughout; inspection ensures quality.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
