Linear low-density polyethylene PE raw material has a wide temperature window, making process parameter optimization difficult
Sorun Belirtisi
PE materials have a wide processing temperature range (190-250°C), and there is a lack of basis for how to select the optimal temperature in actual operation.
Improper temperature selection harms energy consumption, product quality and production efficiency.
Neden Analizi
(1) Different PE grades have different optimal processing temperatures
(2) Temperature setting lacks a systematic method
(3) Operators set temperatures based on experience
(4) Temperature is not optimized according to product characteristics and quality requirements
(5) The matching relationship between temperature and screw speed is unclear
Çözüm
(1) Establish a processing temperature database for each PE grade
(2) Optimize the temperature of each section through design of experiments (DOE)
(3) Appropriately increase temperature to improve fluidity for thin-walled products
(4) Appropriately decrease temperature to reduce shrinkage for thick-walled products
(5) Standardize temperature adjustment records and establish optimal process parameter archives
Temel Çıkarım
PE temperature window optimization needs to be advanced from two aspects: systematic experiments and experience accumulation.
