PARA Back Pressure Management
Fenómeno del problema
Too-high PARA back pressure causes shear heat and fiber damage; insufficient back pressure causes uneven mixing; grasping the 0~10bar window.
Análisis de la causa
PARA back pressure recommends a low hydraulic level of 0~10bar; high back pressure increases melt temperature and shear; fiber damage risk; balance between mixing demand and protection.
Solución
①Control back pressure at a low level of 0~10bar; ②Prioritize raising temperature when mixing is insufficient; ③Fiber integrity verification; ④Measured melt temperature monitoring.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PARA back pressure of 0~10bar is low-shear protection; fiber integrity is the foundation of reinforcement effect; measured temperature prevents overheating.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
