Qualitative detection method of anti-forgery information attenuation rate of cigarette fluorescent anti-forgery stay wire

Abstract

The invention discloses a qualitative detection method of anti-forgery information attenuation rate of cigarette fluorescent anti-forgery stay wire. The method utilizes a sunshine imitation cabinet to simulate different sunlight exposure environments under different temperatures and time periods so as to observe the change of a product under different environments; and then carries out detection on the fluorescent strength by using a spectrophotometric color photometer so as to determine the attenuation of the cigarette fluorescent anti-forgery stay wire. The qualitative detection method fills the technical blank in the field of attenuation rate detection of fluorescent anti-forgery materials at present, the detection results can represent recessive anti-forgery information attenuation period, so the qualitative detection method has a positive meaning for early warning in production and scientific using of anti-forgery materials. The method is simple and practicable, the detection result is objective and scientific, and the method is easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of cigarette material detection, and in particular relates to a method for qualitatively detecting the anti-counterfeit information decay rate of red fluorescent anti-counterfeit pull wires for cigarettes. Background technique [0002] Fluorescent anti-counterfeiting technology has been widely used in the field of raw and auxiliary materials for cigarettes. It has the characteristics of strong concealment, acid and alkali resistance, abrasion resistance and insoluble in water. It can accurately identify the authenticity of products within a certain range and protect consumers' safety. Legitimate rights and interests. At the same time, the fluorescent anti-counterfeiting technology also has some defects: because the fluorescent ink is easy to change under long-term light, it is not suitable for long-term use outdoors. Attenuation of anti-counterfeiting information, specifically manifested as quality defects ...

Problems solved by technology

At the same time, the fluorescent anti-counterfeiting technology also has some defects: because the fluorescent ink is easy to change under long-term light, it is not suitable for long-term use outdoors. Attenuation of anti-counterfeiting information, specifically characterized by quality defects that fade or even disappear

[0004] However, research has found that the disappearance speed of fluorescent anti-counterfeiting is not consistent, and there are obvious differences in the attenuation degree of anti-counterfeiting pull wire products for cigarettes produced by different manufacturers in the sun, that is, some products have red fluorescent anti-counterfeiting information in the sun for 7 days. It basically disappears. Although some products have obvious changes in the sun, after a certain degree of attenuation, the attenuation trend gradually slows down, and its anti-counterfeiting information has not completely disappeared.

The difference in the attenuation rate of anti-counterfeit pull wires for cigarettes is easy for criminals to find an opportunity to deceive and damage the interests of consumers with fake ones.

Therefore, it is necessary to find an effective way to check the anti-counterfeiting information of the anti-counterfeiting pull wire used in cigarettes to accurately judge its attenuation rate, but there is no effective detection method at present.
