PP Transparent Part Haze
Sorun Belirtisi
【Problem Phenomenon】Random copolymer PP transparent parts have high haze
Neden Analizi
High crystallinity causes haze to rise; insufficient nucleation; shear stress; improper cooling; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Çözüm
Add nucleating agent to refine spherulites; control crystallinity; low shear; uniform cooling; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
For PP transparent part haze check crystallization, nucleating agent is the key; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
