Obvious EMA surface color difference
문제 현상
Color shades vary at different parts of EMA products with color difference ΔE>5
원인 분석
Color masterbatch granules unevenly dispersed; pigment orientation during injection causes uneven color distribution; barrel temperature fluctuation causes color change
해결 방법
1) Use color masterbatch masterbatch method to ensure uniform dispersion; 2) Reduce injection speed to reduce pigment orientation; 3) Stabilize barrel temperature within ±2°C
핵심 요약
Color difference is caused by uneven dispersion and orientation; masterbatch method and stable processing are key
