PVA internal delamination cracking
Sorun Belirtisi
PVA product interior delaminates and cracks along the interface
Neden Analizi
Poor interfacial bonding between PVA and incompatible filler or blend components; cooling shrinkage differences cause interlayer stress
Çözüm
1) Use compatibilizer to improve interfacial bonding; 2) Uniform cooling to reduce interlayer stress; 3) Reduce the amount of incompatible components added
Temel Çıkarım
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are the key
