- Investigating, Analyzing Materials By Fluorescence Or Luminescence (AREA)
Abstract
The invention relates to the technical field of glue detection and discloses anti-counterfeiting glue and an anti-counterfeiting detection method thereof. The anti-counterfeiting detection method of the glue comprises the process of detecting whether fluorescence and/or magnetism exists in the glue. When the glue contains anti-counterfeiting particles with fluorescence performance, only light irradiation is needed, fluorescence can be emitted from the glue, and therefore the glue with the same appearance is distinguished; similarly, when the glue contains magnetic anti-counterfeiting particles, only a magnetic field is needed to be applied to the glue to see whether the glue contains enriched particles, so that the glue with the same appearance can be distinguished; when the anti-counterfeiting particles in the glue have both fluorescence and magnetism, the glue with the same appearance can be distinguished by using the fluorescence effect and the magnetism enrichment effect.
Description
Technical Field
The invention belongs to the technical field of glue detection, and particularly relates to anti-counterfeiting glue and an anti-counterfeiting detection method thereof.
Background
