PCL recycling utilization
Problem Phenomenon
PCL recycled material performance and processing, multiple heat history influence.
Cause Analysis
PCL recycling heat history; molecular weight changes; degradation accumulation; performance decay; application fields.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Recycling times limitation; ②Performance testing; ③Ratio control; ④Application matching; ⑤Quality traceability.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Heat history management of PCL recycling is the core; testing and traceability ensure quality; matching reduces risk.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
