Problems solved by technology

[0003] For a long time, research on the microstructural changes in the combustion process of cigarettes has been slow, mainly due to the particularity of the cigarette structure. The shredded tobacco in the combustion cone is extremely brittle, and it is easy to damage the surface and internal structure of the combustion cone during the cutting process, so it is difficult to In-situ analysis and observation of the internal structure of the combustion cone

Embodiment 1

[0045] The steps of embedding and fixing cigarette burning cones are as follows:

[0046] (1) Sampling: Take a sample of cigarette and light it, draw it to the third puff in the standard mode, and quickly put the cigarette into the circular glass casing to make the cigarette go out quickly. Carefully remove the ash-wrapped part, and store the cigarettes in a freezer at -10°C to -5°C for later use.

[0047] (2) Embedding: Mix the embedding agent I: 1,2,3-propanetriol dehydrated glyceryl ether, dodecenyl succinic anhydride, and N-methylol acrylamide according to the molar ratio of 1:0.2:0.49. , fix the cigarette vertically, and place the burning cone end in the embedding tube. Slowly drop into the embedding agent I, infiltrate at room temperature for 2 hours, and then slowly drop into the embedding agent II. The molar ratio of -methylolacrylamide and 2,4,6-tris(dimethylaminomethyl)phenol is 1:0.2:0.49:1.

[0048] (3) Curing: placed in an oven, cured at 60°C for 12 hours.

Embodiment 2

[0053] Such as Figure 4As shown, the cigarette burning cone fixing device of the present invention includes a base 1, and an embedded pipe support 6 is arranged on the base 1; The embedding tube 5 is 8mm-12mm; the opening of the embedding tube 5 is vertically set up; the base 1 is also equipped with a cigarette holder 2 that can move up and down smoothly; the cigarette holder clamps After the cigarette 3 is placed, the cigarette 3 is located directly above the embedding tube, and the burning cone end faces the opening end of the embedding tube 5 .

[0054] When using, first take a cigarette sample and light it, smoke it to the third puff in the standard mode, quickly put the cigarette into the circular glass casing, and make the cigarette extinguish quickly; carefully remove the ash-wrapped part, and fix the cigarette 3 vertically Put it on the cigarette holder 2, and adjust the height so that the combustion cone 4 extends into the embedding tube 5 as a whole; slowly drop th...

Abstract

The invention discloses a cigarette combustion cone fixing method and device. The cigarette combustion cone fixing method has the advantages that an internal structure of a cigarette combustion cone is obtained in situ, the defect of the traditional method that in situ observation can not be carried out on a microstructure inside a cigarette combustion cone part is overcome, the microstructure of the cigarette combustion cone is reserved to the utmost extent, and evidence is provided for intensively studying a cigarette combustion process and a harmful substance production mechanism.

Description

technical field [0001] The invention relates to a method and a device for fixing a cigarette burning cone, belonging to the field of cigarettes. Background technique [0002] The aroma of cigarettes comes from the combustion process, but the combustion also produces a large number of harmful components, which are closely related to the combustion state. Therefore, the research on the combustion state has an important guiding role in reducing tar and harm in the tobacco industry. [0003] For a long time, research on the microstructural changes in the combustion process of cigarettes has been slow, mainly due to the particularity of the cigarette structure. The shredded tobacco at the combustion cone is extremely brittle, and it is easy to damage the surface and internal structure of the combustion cone during the cutting process, so it is difficult to In situ analysis and observation of the internal structure of the combustion cone. Therefore, it is necessary to find a simp...
