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