Low Elongation at Break of CMC
ظاهرة المشكلة
Elongation at break of CMC products <100%, lower than the 200% requirement
تحليل الأسباب
CMC molecular weight is low, chains are short and entanglement is insufficient; excessive orientation makes transverse elongation extremely low; excessive crosslinking limits chain slippage
الحل
1)Select high-molecular-weight CMC to increase entanglement density; 2)Reduce orientation and lower injection speed; 3)Control crosslinking degree to avoid excess
الخلاصة الأساسية
Low elongation at break is caused by low molecular weight and orientation; selecting high MW and reducing orientation are the key
