Difficult EMA machine purging

문제 현상

EMA purging requires 2-3h, affecting changeover efficiency

원인 분석

EMA has strong adhesion forming a firm adhered layer on the screw and barrel; EMA has poor thermal stability and becomes sticky at high temperature, making it harder to remove

해결 방법

1) Flush with high-viscosity PE before purging to carry away EMA residue; 2) Lower purging temperature below EMA softening point to reduce adhesion; 3) Use dedicated purging compound

핵심 요약

Difficult purging is caused by EMA's strong adhesion; PE flushing and temperature reduction are key
