Improper Production Environment Control During Processing of High-Density Polyethylene High-Density Polyethylene
Sorun Belirtisi
Large changes in workshop temperature and humidity cause product quality fluctuations, especially obvious differences in product dimensions and appearance between day and night.
Improper environment control affects process stability and product consistency.
Neden Analizi
（1）Environmental temperature changes affect the mold cooling effect and product shrinkage rate
（2）High environmental humidity causes the raw material to absorb moisture
（3）The workshop has no air conditioning installed or the air conditioning effect is poor
（4）The morning and evening temperature differences affect the cooling water temperature
（5）Airflow (such as opening and closing doors) affects the stability of the blown film cooling line
Çözüm
（1）Install an air conditioning system in the production workshop, controlling the temperature at 20-25°C and the humidity ≤60%
（2）Install a constant temperature device in the cooling system to ensure stable cooling water temperature
（3）Control the temperature of the '2079851475616104452 workshop and the extrusion workshop in separate zones
（4）Install wind shields in the blown film workshop to isolate external airflow
（5）Establish an environmental parameter recording system and adjust process parameters in time
Temel Çıkarım
The production environment is an important factor affecting processing quality, and a complete environmental control system needs to be established.
