PPO Barrel Zone Temperature Setting
Problembeschreibung
【Problem Phenomenon】PPO barrel temperature settings jump greatly, plasticization is uneven and melt temperature is scattered
Ursachenanalyse
SABIC general NORYL zones are: rear 250-270℃, middle 270-290℃, front 280-300℃, nozzle 280-300℃, hopper 60-80℃; progressive heating ensures plasticizing quality
Lösung
Set zone temperatures progressively from low at the rear to high at the front; hopper 60-80℃ to prevent bridging; measure actual melt temperature to calibrate zone settings; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Wichtigste Erkenntnis
PPO barrel progressive heating from 250 to 300℃, hopper 60-80℃ prevents bridging; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
