ABAK recycled material utilization
Problem Phenomenon
The performance of recycled ABAK decreases; phase separation and degradation accumulate; high-value recycling is difficult.
Cause Analysis
When ABAK is recycled, phase separation makes it difficult to regenerate high-value products; accumulation of thermal history; failure of compatibilizer; performance decay; imperfect recycling system.；during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Control of recycling ratio; ②performance verification; ③downgraded utilization; ④exploration of chemical depolymerization recycling; ⑤closed-loop recycling system.；after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
Phase separation in ABAK recycling is a technical difficulty; downgraded utilization is the current reality; closed-loop recycling is the development direction.；after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
