Anode organic dyes why intolerant uv test
Femtosecond detection found that organic dye dyeing is the anodized parts immersed in organic dyes containing the solution, so that the dye into the pores of the film layer of the adsorption layer to achieve the purpose of dyeing. As the adsorbed dye is not strong enough. So that the color of the film is easily wiped off and the abrasion resistance is poor. In addition, organic dyes in the long-term exposure to sunlight can easily fade, and thus poor light resistance. Organic dyes in the ultraviolet light under the electron transition occurs, prone to degradation and oxidation
