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