Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cigarettes, and in particular to an aerosol generating substrate and an aerosol generating product for an electric heating device. Background Art
[0002] In recent years, as the tobacco control situation has become increasingly severe and consumers' attention to health has gradually increased, new tobacco products have become more and more popular among the public. After rapid development and optimization in recent years, aerosol-generating products such as heated cigarettes have initially achieved a good smoking experience. Due to the special heating method of heated cigarettes, the tobacco material itself cannot release enough aerosols, and the amount of smoke is relatively small, so it is usually necessary to add an atomizer to supplement the smoke generated after heating. However, when the atomizer is exposed to the air, it absorbs moisture in the air, thereby increasing the water content of the heated cigarette, making the moisture content of the smoke in the first two puffs (especially the first puff) of the heated cigarette too high. The increase in heat capacity causes users to feel a burning sensation in their mouths when smoking heated cigarettes, and the user experience is not good.
[0003] The main solution at present is to increase the sealing of the cigarette box to prevent the heated cigarette from absorbing moisture in the air, or to reduce the amount of atomizer added to reduce the hygroscopicity of the heated cigarette. However, it has been found in practice that this treatment has not been able to solve the above technical problems. Summary of the invention

[0126] Test Example 1
[0127] The instrument is a thermogravimetric-mass spectrometer (TG-MS) (NETZSCH STA 449F3 + QMS 403D, Germany). The setting parameters are: atmosphere: nitrogen; protective gas flow: 20mL / min; purge gas flow: 50mL / min; temperature: 40-390℃; heating rate: 20℃ / min. The experimental steps are as follows: grind the sample into powder, put the sample into the instrument, adjust the parameters, start the experiment and record the water ion flow intensity-temperature curve. The test data are shown in Tables 1 to 3.

[0131]
[0132]
[0133] Table 3
[0134]
[0135] In the above, a represents the peak point in the free water evaporation interval; b represents the trough point at the junction of the free water evaporation interval and the cell water evaporation interval; c represents the peak point in the cell water evaporation interval; d represents the trough point at the junction of the cell water evaporation interval and the pyrolysis water evaporation interval; e represents the peak point in the pyrolysis water evaporation interval. T0 is the temperature value of the plant material at this point, T n is the temperature of the sample at that point, A0 is the ion current intensity of the plant material at that point, A n is the ion current intensity value of the sample at that point.
[0136] During the heating process of the sample at 40-390℃, water is continuously generated. The first water ion current intensity peak (corresponding to point a0) is mainly caused by the evaporation of free water in the sample; the second water ion current intensity peak (corresponding to point c0) is mainly caused by the release of water from the inside of the cell due to the thermal destruction of the cell wall; the third water ion current intensity peak (corresponding to point e0) is mainly caused by the thermal decomposition of the cell wall components.
[0137] As can be seen from Table 1-3, the water ion current intensity peak near 100°C (corresponding to point a0) is mainly caused by the volatilization of free water in the sample; the second water ion current intensity peak appears near 208°C (corresponding to point c0), and the third water ion current intensity peak appears near 308°C (corresponding to point e0). After the sample is mixed with the additive, the water ion current intensity signal intensity near 100°C increases as a whole, which indicates that the reaction of the sample to produce water vapor is advanced, which can make the sample dehydrated in advance during the preheating stage, thereby reducing the amount of water released during the first puff after heating.
