Problems solved by technology

[0005] The present invention aims at providing a method that cannot accurately characterize the influence of pore structure parameters such as pore size distribution and pore volume of cigarette paper on the amount of CO released in mainstream smoke during the burning process of cigarettes in the prior art, which cannot meet the needs of industry development. This method is simple to operate and can accurately characterize the relationship between the pore volume, pore size distribution and other pore structure parameters of cigarette paper during the combustion process of cigarettes, and the CO release in mainstream smoke, providing theoretical guidance for cigarette research and production

Embodiment 1

[0030] 1) Take A, B, and C three groups of 1# cigarette paper samples of the same type, and A cigarette paper includes A of the same type 1 and A 2 Cigarette paper, B cigarette paper including B 1 and B 2 cigarette paper;

[0031] Accurately weigh the mass of each cigarette paper sample: put the cigarette paper to be tested into a pre-weighed nitrogen adsorption-desorption sample tube, and pre-dry at 80°C for about 5 hours under nitrogen purge until all the water vapor is absorbed. Take it away, the quality of the cigarette paper will not change, put the dried sample tube in the cooling tank to cool to room temperature, weigh the quality of the sample tube again, and obtain the cigarette paper A 1 with B 1 The masses are 0.2228g and 0.2045g respectively, and put into the blank sample tube as a reference at the same time;

Abstract

The invention discloses a method for testing the relation between a cigarette paper pore structure and CO release in main stream smoke in the cigarette burning process. According to the method, the state of cigarette paper nearby a charring line in the cigarette burning process is simulated through baking in combination of a nitrogen absorption and desorption method and a mercury intrusion method, distribution of pore volumes and pore diameters in the range of 1 nm-200 mu m of the cigarette paper before and after baking is represented respectively, the pore structure change of the cigarette paper in the cigarette burning process is more accurately represented, and data of the CO release in main stream smoke of a cigarette are further combined, so that the relation between the cigarette paper pore structure and the CO release in main stream smoke in the cigarette burning process can be accurately obtained, and theoretical direction is provided for research and production of cigarette paper with low CO release.

Description

technical field [0001] The invention relates to a method for testing the relationship between the pore structure of cigarette paper and the amount of CO released in mainstream smoke during the burning process of cigarettes, belonging to the field of cigarettes. technical background [0002] How to reduce the amount of CO and tar in the mainstream smoke of cigarettes and reduce the harm of smoking to human health is an important research topic in the cigarette industry. With the continuous improvement of people's living standards, consumers are becoming more and more aware of the safety of smoking. Therefore, the development of low-CO emission and low-harm cigarettes is not only an inevitable trend in the development of the tobacco industry, but also an important issue for the State Tobacco Monopoly Administration of cigarettes in the industry. One of the development strategies for reducing tar and harm. [0003] Cigarette paper is located at the outermost periphery of cigar...
