Comparative Study on UV Degradation of Black Chinese Lacquers with Different Additives.

This study investigates the UV degradation of black Chinese lacquer by incorporating carbon black and ferrous hydroxide as additives. The purpose of this research is to understand the effects of these additives on the degradation behavior of the lacquer film. Different concentrations of carbon black powder (1%, 3%, and 5%) and Fe(OH) (10%, 20%, and 30%) were added to the lacquer following traditional techniques.
