Embodiment 1

[0065] The design test of embodiment 1 composition formula

[0066] 1. Orthogonal test verification

[0067] The present invention determines that the main components participating in the reaction are aluminum powder or magnesium powder, potassium permanganate, manganese dioxide, tartaric acid, potassium hydrogen tartrate, anhydrous magnesium sulfate, and the consumption of activated carbon as the main influencing factors. Five levels, using six factors and five levels L25 (56) orthogonal experimental design scheme for experimental verification. To avoid redundant description, this embodiment provides the orthogonal test data of aluminum powder as an example for illustration.

[0068] According to the orthogonal test design, determine reasonable influencing factors and level dosage, because aluminum powder or magnesium powder, potassium permanganate and acidic substances are necessary substances for the reaction, while manganese dioxide, anhydrous magnesium sulfate and activa...

Embodiment 2

[0107] The detection of embodiment 2 overall reaction rate

[0108] According to the known reaction principle, combined with the addition amount of each reactant in the reaction, the theoretical value of manganese content in the obtained sample can be calculated. The sampling positions are divided into the whole reaction product, the inner and outer layers of the product, the upper layer of the product (the end closer to the copper tube cover), the middle layer and the lower layer (the end farther away from the copper tube cover), and the weighed mixed solid generates heat The material mass is m 0 . Knowing the proportion of potassium permanganate added, it can be known that the mass of potassium permanganate in the mixed solid material is m 1 , the mass of added aluminum powder or magnesium powder is m 2 , the amount of substances of potassium permanganate and metal reactant can be calculated as n 1 and n 2 , where n 1 =m 2 / M KMnO4 , n 2 =m metal / M metal . An ex...

Abstract

The present invention discloses a magnesium-based heating source composition of non-combustion cigarettes based on a chemical self-heating reaction. The composition consists of the following components by mass percentage: 3.0%-14.5% of magnesium powder; 48.6%-72.7% of potassium permanganate; 5.7%-11.9% of acidic substance, 0%-14.4% of anhydrous magnesium sulfate; 0%-9.4% of activated carbon; 9.7%-12.5% of NaCl; and 0%-6.1% of manganese dioxide. The present invention provides the novel composition as the heating source of the non-combustion heated cigarette. The composition raises the temperature in a higher rate; the highest temperature is higher; the duration is longer; the activation is easy to operate; the heating efficiency is high enough; the heat release time meets requirements; the volume of a heating chamber decreases due to a smaller amount in usage; and the composition is safe and easy for using and transportation, and is relatively low in cost, thereby having significant promotion and application value.

Description

technical field [0001] The present invention relates to the technical field of non-combustible cigarettes, and more specifically relates to a magnesium-based heat source composition for non-combustible cigarettes based on chemical self-heating reaction and its application. Background technique [0002] In recent years, the total annual production and sales volume of all tobacco products in the world has shown a downward trend, but the annual production and sales volume of non-burning tobacco products has shown an increasing trend instead. The diversification of tobacco products has new development opportunities for the entire tobacco industry and tobacco companies in various countries. The research and development of new tobacco products provides a new development direction for the tobacco industry and has a good development prospect. [0003] Tobacco products with various structures, different mechanisms and different smoking methods have appeared in the tobacco market. Th...
