PBAT recycling utilization
문제 현상
PBAT recycled material performance declines, and degradation accumulates with multiple reuses.
원인 분석
PBAT is heat history sensitive; recycled material molecular weight decreases; impurity contamination; hydrolysis accumulation; performance decay.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①Limit recycling times; ②recycled material quality screening; ③performance verification; ④proportion control.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Molecular weight management is the core of PBAT recycling; control of times and proportion; verification ensures quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
