TPU Film Extrusion
Sorun Belirtisi
TPU film transparency decreases with gel particles, and heat-seal strength is unstable
Neden Analizi
TPU film has high requirements for drying and filtration; moisture and degradation form gel particles; uneven thickness affects heat sealing; cooling roll temperature affects transparency; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Çözüm
①Strictly dry to 0.02%; ②High-efficiency filtration to remove gel particles; ③Optimize cooling roll temperature; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
TPU film is a double high standard of drying and filtration; the 0.02% red line plus precision filtration is the foundation of transparency; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
