DSTDP surface stress whitening
ظاهرة المشكلة
DSTDP product surface stress whitening in stressed regions, affecting appearance and strength
تحليل الأسباب
Under local stress, DSTDP molecular orientation causes refractive index difference and whitening; product internal stress concentration regions
الحل
1) Reduce injection speed to reduce orientation stress; 2) annealing treatment 80°C/2h to release stress; 3) product design to avoid stress concentration sharp corners
الخلاصة الأساسية
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
