Glass Fibre surface stress whitening
Sorun Belirtisi
Glass Fibre product stressed region surface stress whitening, affecting appearance and strength
Neden Analizi
Glass Fibre under local stress molecular orientation causes refractive index difference and whitening; product internal stress concentration region
Çözüm
1) Reduce injection speed to reduce orientation stress; 2) annealing treatment 80°C/2h to release stress; 3) product design avoids stress concentration sharp corners
Temel Çıkarım
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
