Cooling and sizing parameters affect product dimensions and surface quality
Fenómeno do problema
Cooling and sizing parameters affect product dimensions and surface quality
Análise das causas
Cooling water temperature too high, insufficient sizing
Uneven cooling water distribution, sizing differences
Improper sizing sleeve dimensions, product dimensional deviation
Insufficient cooling length, product not fully sized
Cellulose acetate butyrate crystallinity requires controlling the cooling rate
Solução
Control cooling water temperature 15-25°C
Evenly distribute cooling water
Reasonably design sizing sleeve dimensions
Ensure sufficient cooling length
Control cooling according to cellulose acetate butyrate crystallization characteristics
Conclusão principal
Cooling and sizing need to be controlled according to material characteristics
