Improper production environment control during linear low-density polyethylene linear low-density polyethylene processing
Sorun Belirtisi
Large workshop temperature and humidity changes 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.
Neden Analizi
(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 has no air conditioning installed or the air conditioning effect is poor
(4) Morning and evening temperature differences affect 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 temperature at 20-25°C and humidity ≤60%
(2) Install a constant temperature device in the cooling system to ensure stable cooling water temperature
(3) Control temperature in zones for the injection workshop and the extrusion workshop
(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; a complete environmental control system needs to be established.
