Non-destructive testing method of internal structure of cigarettes during burning

Abstract

The invention discloses a non-destructive testing method of internal structure of cigarettes during burning. The method comprises the steps as follows: placing a cigarette sample in a CT scanner to be scanned to obtain an internal structure of the cigarette sample before burning; igniting the cigarette sample for static burning or normal suction to produce ash; placing the cigarette sample after ash is produced in a closed container to be extinguished, and freezing the cigarette sample; scanning the frozen cigarette sample by the CT scanner to obtain the internal structure of the burnt cigarette, and calculating the change of the internal structure of the cigarette sample before and after burning. With the adoption of the method, the change of the internal structure of the cigarettes in the real burning state can be obtained by analyzing the internal structure of the cigarette sample before and after burning, and the visual basis is provided for further study of the burning process of the cigarettes.

Description

technical field [0001] The invention relates to a method for nondestructively testing the internal structure of a cigarette during combustion, and belongs to the field of cigarettes. Background technique [0002] Cigarettes are made of shredded tobacco, and their internal structure is closely related to the combustion process, such as temperature distribution and airflow field changes during combustion. Most of the chemical composition changes during the burning process of cigarettes have been studied thoroughly, but little progress has been made on the changes in the physical state of cigarettes during the burning process. This process is more described by temperature and products, which is not the case. intuitive. However, microscopic (such as optical microscope and scanning electron microscope, etc.) methods can only observe the structural changes on the surface of the cigarette, and cannot well reproduce the real burning process of the cigarette. Therefore, it is neces...

Most of the chemical composition changes during the burning process of cigarettes have been studied thoroughly, but little progress has been made on the changes in the physical state of cigarettes during the burning process. This process is more described by temperature and products, which is not the case. intuitive

Microscopic methods (such as optical microscopes and scanning electron microscopes, etc.) can only observe the structural changes on the surface of cigarettes, and cannot reproduce the real burning process of cigarettes well.
