A quality discrimination method for cigarette wrapping paper based on dfa and sqc models

Abstract

The invention discloses a cigarette packaging paper quality discriminating method based on DFA and SQC models. The method comprises the following steps: S1, preparing qualified samples; S2, preparing unqualified samples, wherein the unqualified samples include benzene unqualified samples and VOCs( Volatile Organic Chemicals) unqualified samples; S3, adopting an electronic nose system to acquire smell information of the qualified samples and the unqualified samples; S4, conducting normalization processing to the original data acquired by the electronic nose system, extracting characteristic data, building a database, constructing the DFA model and the SQC model; S5, utilizing the electronic nose system to acquire data of a to-be-detected sample, substituting the data into the corresponding DFA model and the SQC model constructed in the step S4, and conducting discriminant analysis. With application of the method disclosed by the invention, the discriminating time of benzene and VOCs except for benzene can be respectively shortened by 1 / 5 and 1 / 6 of that in the prior art, so as to shorten the whole quality discriminating cycle; furthermore, the method has the advantages of simple pretreatment, high degree of accuracy, good repeatability and the like, and can provide strongly support for the security and the adaptation of the cigarette packaging paper.

Description

technical field [0001] The invention belongs to the technology for identifying the quality of packaging paper for cigarettes, in particular to a method for identifying the quality of packaging paper for cigarettes based on DFA and SQC models. Background technique [0002] At present, as the demand for tobacco products continues to rise, the competition among the tobacco industry has intensified. While improving the taste of cigarettes, various tobacco companies are pursuing novel, exquisite and high-grade outer packaging to attract consumers' attention. Therefore, it is inevitable to use a large amount of ink, solvents and additives in the paper production process, resulting in unvolatile organic compounds (VOCs) remaining in the finished cigarette packaging paper. Excessive VOCs not only affect the smoking taste of cigarette products but also threaten human health. In particular, benzene in VOCs can accumulate in the nervous system and bones, damage the nervous system and ...
