PC recycled material management
문제 현상
【Problem Phenomenon】PC recycled material ratio out of control, performance and color phase decline
원인 분석
PC recycled material has multiple heat histories with decreased molecular weight and moisture content hard to control; out-of-control ratio causes both impact strength and color phase to decline；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
해결 방법
Recycled material dried separately and moisture content verified; ratio control; prohibited for performance parts and transparent parts；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
핵심 요약
PC recycled material moisture content is hard to control, prohibited for performance and transparent parts；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence；Include this case in the defect archive as a reference for troubleshooting similar problems in the future
