DSTDP internal delamination cracking
ظاهرة المشكلة
DSTDP product interior delaminates, cracking along the interface
تحليل الأسباب
DSTDP has poor interfacial bonding with incompatible filler or blend components; cooling shrinkage differences cause interlayer stress
الحل
1) Use compatibilizer to improve interfacial bonding; 2) uniform cooling to reduce interlayer stress; 3) reduce the addition amount of incompatible components
الخلاصة الأساسية
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are key
