Glass Fibre shrinkage rate unstable
ظاهرة المشكلة
Glass Fibre product shrinkage rate fluctuates ±0.8%, exceeding ±0.2% requirement
تحليل الأسباب
Glass Fibre different batches molecular weight difference causes shrinkage rate change; processing temperature fluctuation affects crystallinity thus affecting shrinkage rate
الحل
1) Strictly control raw material batch consistency; 2) processing temperature stable ±2°C to ensure consistent crystallinity; 3) mold shrinkage compensation reserves adjustment space
الخلاصة الأساسية
Unstable shrinkage rate is caused by batch difference and temperature fluctuation; raw material and temperature control are key
