Metallocene linear low density polyethylene metallocene linear low density polyethylene improper production environment control during processing
Fenómeno do problema
Large changes in workshop temperature and humidity cause product quality fluctuations, especially obvious differences in product dimensions and appearance between day and night.
Improper environmental control affects process stability and product consistency.
Análise das causas
（1） Ambient temperature changes affect mold cooling effect and product shrinkage rate\
（2） High ambient humidity causes raw material to absorb moisture\
（3） The workshop is not equipped with air conditioning or the air conditioning effect is poor\
（4） Morning-evening temperature differences affect cooling water temperature\
（5） Airflow （such as opening and closing doors） affects blown film cooling line stability
Solução
（1） Install an air conditioning system in the production workshop, control temperature at 20-25°C, humidity ≤60%\
（2） Install a constant temperature device in the cooling system to ensure stable cooling water temperature\
（3） Zone temperature control for the '2079851475616104452 workshop and extrusion workshop\
（4） Install wind shields in the blown film workshop to isolate external airflow\
（5） Establish an environmental parameter recording system, adjust process parameters in time
Conclusão principal
The production environment is an important factor affecting processing quality, requiring the establishment of a sound environmental control system.
