Product delamination and peeling
Sorun Belirtisi
The skin layer and core layer of the injection molded product separate, the fracture is layered, and mechanical properties severely decline
Neden Analizi
Insufficient compatibility of blended components and weak interface bonding; dispersed phase particle size too large (>10μm); excessive injection shear rate causes phase separation
Çözüm
Select a suitable compatibilizer (MAH graft, etc.); optimize screw shear combination to make dispersed phase particle size <1μm; use multi-stage injection speed to reduce phase separation
Temel Çıkarım
The essence of delamination is interface bonding failure caused by thermodynamic incompatibility
