Glass Fibre surface stress whitening
ظاهرة المشكلة
Glass Fibre product stressed region surface stress whitening, affecting appearance and strength
تحليل الأسباب
Glass Fibre under local stress molecular orientation causes refractive index difference and whitening; product internal stress concentration region
الحل
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
الخلاصة الأساسية
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
