Poor Surface Gloss of CMC
ظاهرة المشكلة
Surface gloss of CMC products <60%, lower than the 80% requirement, with dull appearance
تحليل الأسباب
Mold surface is rough Ra>0.4μm; CMC crystallinity is high and surface microcrystals scatter light; improper cooling rate
الحل
1)Polish mold to mirror finish Ra<0.1μm; 2)Increase mold temperature to delay crystallization and reduce scattering; 3)Add nucleating agent to control crystal size
الخلاصة الأساسية
Poor gloss is caused by mold roughness and crystallization scattering; polishing the mold and controlling crystallization are the key
