PP Back Pressure and Screw
Fenómeno do problema
PP back pressure and screw speed management; balance of shear heat and plasticizing.
Análise das causas
PP back pressure management; high back pressure shear heat; low back pressure uneven plasticizing; screw speed coordination; melt uniformity; temperature monitoring.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solução
①Moderate back pressure control; ②Screw speed coordination; ③Shear heat monitoring; ④Actual melt temperature measurement; ⑤Plasticizing quality.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
The coordination of PP back pressure and screw is plasticizing quality; shear heat management protects the material; actual measurement prevents deviation.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
