PPO '2079851475616104452 Machine Type Selection
Fenómeno del problema
【Problem Phenomenon】Evaluating the feasibility of plunger-type and screw-type '2079851475616104452 machines for processing PPO
Análisis de la causa
Both plunger-type and screw-type '2079851475616104452 machines can process PPO; screw-type is generally used and requires an L/D ratio greater than 15:1; screw-type plasticizing uniformity is more suitable for high-viscosity materials
Solución
Select screw-type '2079851475616104452 machines for mass production and meet the L/D requirement; plunger-type is limited to simple products; evaluate screw wear resistance for high-filled grades; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusión clave
Screw-type is the mainstream for PPO '2079851475616104452, and L/D greater than 15:1 is the entry condition; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
