DSTDP surface stress whitening
Sorun Belirtisi
DSTDP product surface stress whitening in stressed regions, affecting appearance and strength
Neden Analizi
Under local stress, DSTDP molecular orientation causes refractive index difference and whitening; product internal stress concentration regions
Çözüm
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
Temel Çıkarım
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
