Improper Production Environment Control in Polypropylene Processing
문제 현상
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.
원인 분석
(1) Environmental temperature changes affect the mold cooling effect and product shrinkage
(2) High environmental humidity causes the raw material to absorb moisture
(3) The workshop is not installed with air conditioning or the air conditioning effect is poor
(4) The temperature difference between morning and evening affects the cooling water temperature
(5) Airflow (such as opening and closing doors) affects the stability of the blown film cooling line
해결 방법
(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 in zones for the '2079851475616104452 workshop and the extrusion workshop
(4) Install a wind shield in the blown film workshop to isolate external airflow
(5) Establish an environmental parameter recording system and adjust process parameters in time
핵심 요약
The production environment is an important factor affecting processing quality, and a sound environmental control system needs to be established.
