PLA Nucleating Agent Accelerating Crystallization
문제 현상
PLA crystallizes slowly with a long molding cycle and insufficient crystallization, and the product performance is unstable
원인 분석
PLA crystallization kinetics is slow, and crystallization is insufficient during processing; nucleating agents accelerate crystallization and shorten the cycle; nucleating agents such as talc are common solutions; degradation conversely accelerates the crystallization kinetics
해결 방법
①Add nucleating agent (talc etc.) to accelerate crystallization; ②Mold heating and holding to promote crystallization; ③Monitor crystallinity consistency; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Nucleating agents are the standard means of PLA crystallization management; balancing cycle and performance relies on crystallization rate control; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
