Anti-aging and sun-protective artificial plant wall

Plastics and other polymer materials placed outdoors, under the influence of sunlight and fluorescence, undergo an auto-oxidation reaction due to the effect of ultraviolet rays, leading to the degradation and deterioration of the polymers, which makes their appearance and mechanical properties deteriorate. At this time, it is necessary to add ultraviolet absorbers to achieve the purpose of color protection and anti-aging. 

Most ultraviolet absorbers are aromatic compounds containing benzene rings, which can absorb ultraviolet rays. The absorbers absorb the energy of ultraviolet rays due to the resonance effect of the benzene rings and convert it into heat energy or light energy without destructive effects, and then return to their original molecular structure. In this way, the absorber can be used repeatedly without damaging the absorber itself, which is a chemical anti-ultraviolet principle.
