Uneven color of EVA mixed with color masterbatch
ظاهرة المشكلة
EVA/color masterbatch injection molded products show color streaks and areas of uneven color depth
تحليل الأسباب
Color masterbatch carrier resin incompatible with EVA; poor color masterbatch dispersion with pigment agglomeration; unstable melt flow during '2079851475616104452 causing pigment orientation
الحل
1) Select color masterbatch with EVA or similar carrier to ensure compatibility; 2) Twin-screw extrusion pelletizing for pre-dispersion; 3) Appropriately extend mixing time to ensure pigment dispersion; 4) Reduce injection speed to reduce pigment orientation
الخلاصة الأساسية
Color masterbatch carrier matching and sufficient dispersion are key to color uniformity
