Embodiment 1

[0034] Embodiment 1, this embodiment takes the first batch of cigarette paper samples (batch A cigarette paper) of a certain brand and specification as a reference, and compares the second batch of cigarette paper samples (batch B cigarette paper) of the same brand and same specification. ) quality stability. The specific operation includes the following steps:

[0035] Step 1. Preprocessing

[0036] Cut the cigarette paper into 1mm 2 sized fragments, and then baked in an oven at 50°C for 48 hours, and then placed in a desiccator for later use;

[0037] Step 2, thermogravimetric analysis

[0038] Place the empty crucible on the test balance of the thermogravimetric analyzer, and when the temperature in the furnace reaches the initial temperature of the thermogravimetric program at 50°C, clear the mass number of the balance; weigh 10 ± 1 mg of pretreated cigarette paper and place it in the crucible. When the temperature in the furnace stabilizes and reaches the initial temp...

Embodiment 2

[0058] This embodiment takes the first batch of cigarette paper samples (batch A cigarette paper) samples in Example 1 as a reference, and compares the quality stability of the third batch of cigarette paper samples (batch C cigarette paper) of the same brand and same specification sex.

[0059] image 3 The two TG curves of Batch C cigarette paper and A av atlas.

[0060] After calculation, the two TG curves of the third batch of cigarette paper samples are relative to A av The discrete values ​​of are 2.33×10 -3 , 4.05×10 -3 , all fall within the discrete interval of the thermogravity curve of the batch A cigarette paper, therefore, it is judged that the quality of the batch C cigarette paper is stable compared with that of the batch A cigarette paper.

Embodiment 3

[0062] Repeat steps 1 and 2 in Example 1 with batch A cigarette paper samples to obtain a new TG curve, denoted as A 6 . in A 1 -A 6 Randomly select 5 curves from the 6 TG curves, repeat step 3 in Example 1, and obtain the discrete intervals of thermal weight loss curves of 6 groups of Batch A cigarette papers, as shown in Table 1. The results of 6 tests show that the average discrete interval is in [0, 6.08×10 -3 ], the relative deviations are all within ± 3.20%, and the coefficient of variation of each group of data is 2.06%, illustrating that the repeatability and precision of the test method of the present invention are better.

[0063] Table 1 The results of the repeatability and precision test of the method (n=6, batch A)

Abstract

The invention discloses a method for determining the quality stability of the cigarette paper. The quality stability of cigarette papers in different batches can be accurately determined by using thermogravimetry (TGA) through comparing the discretivity of the thermogravimetric curve (TG) of the cigarette papers with the same brand and specification and in different batches. The method has the advantages of small amount of needed samples, short analysis time, low cost, simplicity in operation, and accurate experimental result.

Description

technical field [0001] The invention relates to a method for judging the quality stability of cigarette paper, which belongs to the field of tobacco analysis. Background technique [0002] Cigarette paper, as a cigarette auxiliary material, occupies a relatively high position in cigarettes, although its weight only accounts for 5% of the weight of the whole cigarette. Cigarette paper directly participates in combustion, which can control the combustibility of cigarettes and adjust the dilution of smoke, thereby affecting the combustibility of cigarettes, affecting the amount of tar released from cigarettes and changes in other smoke components such as carbon monoxide, and affecting It affects the sensory evaluation and smoking quality of cigarettes (cigarette aroma, etc.). [0003] At present, the research on cigarette paper mostly focuses on the effects of components (fiber raw materials, fillers, additives, etc.) on its combustion characteristics, and then investigates th...
