Surface Stress Whitening of CMC
문제 현상
Surface stress whitening in stressed areas of CMC products affects appearance and strength
원인 분석
Under local stress, CMC molecular orientation causes refractive index differences and whitening; areas of internal stress concentration in the product
해결 방법
1)Reduce injection speed to reduce orientation stress; 2)Annealing treatment at 80°C/2h to release stress; 3)Product design to avoid stress concentration sharp corners
핵심 요약
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are the key
