Qualitative detection method for attenuation rate of anti-counterfeiting information of cigarette fluorescent anti-counterfeiting tear line

Abstract

The invention discloses a qualitative detection method for attenuation rate of anti-counterfeiting information of a cigarette fluorescent anti-counterfeiting tear line. A solarization box device is used to simulate solarization environments having different temperatures and different lengths of time, changes of a product in the different environments are observed, fluorescent strength of the product is detected with a spectrophotometer, and attenuation of the anti-counterfeiting information of the cigarette fluorescent anti-counterfeiting tear line is judged accordingly. The qualitative detection method fills the technical blank in existing measurements for information attenuation of fluorescent anti-counterfeiting materials, the measurement results of the method are indicative of attenuation cycle of concealed anti-counterfeiting information, the method is positively significant to warning-based production and scientific use of anti-counterfeiting materials, and the method is simple and feasible, has objective and scientific examination results and is easy to implement and 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

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 method to check the anti-counterfeiting information of the anti-counterfeiting pull wire used in cigarettes, so as to accurately judge its attenuation rate, and use it to issue early warning at the effective time interval of fluorescent anti-counterfeiting information, but there is no effective detection method at present.
