PPO Hopper Temperature and Bridging Prevention
Sorun Belirtisi
【Problem Phenomenon】PPO pellets soften and bridge in the feed section, feeding is not smooth and production is interrupted
Neden Analizi
Excessively high hopper temperature causes pellets to soften, stick and bridge in the feed section; SABIC recommends hopper temperature of 60-80℃, combined with cooling to keep feeding smooth; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
Control hopper temperature at 60-80℃; check the feed throat cooling water circuit; when bridging occurs, clean and check the feed section temperature; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
Hopper 60-80℃ is the smooth feeding zone for PPO; check here first for over-temperature bridging; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
