PBAT biodegradation rate
문제 현상
The degradation rate of PBAT products does not meet expectations, failing prematurely when too fast or not degrading when too slow.
원인 분석
PBAT crystallinity affects degradation rate; environmental temperature, humidity and microbial conditions; thickness and surface area; influence of blend components; effect of additives.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①Select crystallinity according to application requirements; ②evaluate environmental conditions; ③thickness design matching; ④blend formulation optimization; ⑤degradation test verification.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
The controllability of PBAT degradation rate is the key to application; crystallinity and formulation are the main variables; test verification ensures compliance.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
