문제 현상
Improper use of PBAT lubricant, balancing processing improvement and performance side effects.
원인 분석
Lubricant improves processing flowability; excessive amount migrates and precipitates; affects heat sealing and printing; type selection; dispersion uniformity.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①Lubricant type selection; ②minimize the addition amount; ③uniform dispersion; ④migration and performance testing.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
PBAT lubricant is a double-edged sword as a processing aid; the minimum effective amount is the principle; test and evaluate side effects.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
