EEA Purging Difficulty
Sorun Belirtisi
EEA purging requires 2-3h, time-consuming, affecting changeover efficiency
Neden Analizi
EEA has strong adhesion, forming a firm adhesive layer on the screw and barrel; EEA has poor thermal stability, becoming sticky at high temperature and harder to remove
Çözüm
1) Before purging, flush with high-viscosity PE to carry away EEA residue; 2) Lower the purging temperature below the EEA softening point to reduce adhesion; 3) Use dedicated purging compound
Temel Çıkarım
Purging difficulty is caused by the strong adhesion of EEA; PE flushing and temperature reduction are key
