EEA Surface Stress Whitening
Sorun Belirtisi
Stress whitening on the surface of stressed areas of EEA products, affecting appearance and strength
Neden Analizi
Under local stress, EEA molecular orientation causes refractive index differences and whitening; internal stress concentration areas of the product
Çözüm
1) Reduce injection speed to reduce orientation stress; 2) Annealing treatment at 80°C/2h to release stress; 3) Product design to avoid stress-concentrating sharp corners
Temel Çıkarım
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
