RESIN DETERIORATION EVALUATION TEST METHOD AND RESIN RECYCLING METHOD

A resin deterioration evaluation test method using a fluorescent agent, includes irradiating a resin component with ultraviolet rays and measuring a fluorescence amount emitted by a fluorescent agent in response to the irradiating (STEP S2). The fluorescent agent is on a surface of the resin compone...

Beschreibung
Zusammenfassung:	A resin deterioration evaluation test method using a fluorescent agent, includes irradiating a resin component with ultraviolet rays and measuring a fluorescence amount emitted by a fluorescent agent in response to the irradiating (STEP S2). The fluorescent agent is on a surface of the resin component and emitting fluorescence in resnponse to ultraviolet irradiation in its. The resin deterioration evaluation test method using a fluorescent agent further includes evaluating a deterioration degree of the resin component based on the fluorescence amount (STEP S3).
