Unstable shrinkage of EAA
ظاهرة المشكلة
The shrinkage of EAA products fluctuates ±0.8%, exceeding the ±0.2% requirement
تحليل الأسباب
Molecular weight differences between different batches of EAA cause shrinkage changes; processing temperature fluctuations affect crystallinity and thus shrinkage
الحل
1) Strictly control the consistency of raw material batches; 2) Stabilize the processing temperature ±2°C to ensure consistent crystallinity; 3) Reserve adjustment space for mold shrinkage compensation
الخلاصة الأساسية
Unstable shrinkage is caused by batch differences and temperature fluctuations; raw material and temperature control are the key
