DSTDP surface stress whitening
Fenómeno del problema
DSTDP product surface stress whitening in stressed regions, affecting appearance and strength
Análisis de la causa
Under local stress, DSTDP molecular orientation causes refractive index difference and whitening; product internal stress concentration regions
Solución
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
Conclusión clave
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
