Difficult Machine Purging of CMC
Fenómeno del problema
CMC purging takes 2-3h, affecting changeover efficiency
Análisis de la causa
CMC has strong adhesion and forms a firm adhesive layer on the screw and barrel; CMC has poor thermal stability and becomes sticky at high temperature, making it harder to remove
Solución
1)Flush with high-viscosity PE before purging to carry away CMC residue; 2)Lower purging temperature below CMC softening point to reduce adhesion; 3)Use special purging compound
Conclusión clave
Difficult purging is caused by strong CMC adhesion; PE flushing and temperature reduction are the key
