[Problem Phenomenon] Feasibility and precautions of PC recycling
Neden Analizi
PC is recyclable: crushed, re-dried and blended at ≤20%; multiple heat histories reduce molecular weight; regrind is prohibited for optical parts; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Çözüm
Dry and verify regrind separately; ratio ≤20%; prohibited for optical parts; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Temel Çıkarım
PC recycling is feasible, with a 20% ratio and prohibition for optical 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
