	The export of finished shoes is placed in containers. Due to the influence of solar radiation, shoes and materials are easy to interact with the chemical components they contain, resulting in the color change of shoes. This machine is to simulate the ultraviolet light in the solar light, to test the yellowing resistance of the shoe material, so as to provide reference for the control of chemicals added in the process.
