DSTDP poor surface gloss
Fenómeno do problema
DSTDP product surface gloss <60%, below the 80% requirement, dull appearance
Análise das causas
Mold surface rough Ra>0.4μm; DSTDP crystallinity high, surface microcrystals scatter light; cooling rate improper
Solução
1) Polish mold to Ra<0.1μm mirror finish; 2) raise mold temperature to delay crystallization and reduce scattering; 3) add nucleating agent to control crystal size
Conclusão principal
Poor gloss is caused by mold roughness and crystallization scattering; polishing the mold and controlling crystallization are key
