Degradation producing lactic acid smell during PLA '2079851475616104452
문제 현상
An acidic pungent odor (lactic acid smell) is produced during the '2079851475616104452 process.
원인 분석
PLA hydrolyzes and degrades in the presence of high temperature and moisture to produce lactic acid and oligomers, and high processing temperature aggravates the degradation.
해결 방법
Fully dry to moisture <0.025% (250ppm); control the processing temperature at 170-200°C; strengthen workshop ventilation.
핵심 요약
PLA hydrolysis degradation producing lactic acid smell is a processing environment problem.
