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 invention discloses a magnesium-based heat source composition for non-combustible cigarettes based on chemical self-heating reaction, which is composed of the following components in mass percentage: magnesium powder 3.0%-14.5%; potassium permanganate 48.6%-72.7% %; acidic substances 5.7% to 11.9%; anhydrous magnesium sulfate 0% to 14.4%; activated carbon 0% to 9.4%; sodium chloride 9.7% to 12.5%; manganese dioxide 0% to 6.1%. The invention provides a new composition as a heating source for non-combustion heating cigarettes, which not only has a fast heating rate, but also has a higher maximum temperature and a longer duration. Requirements, because the volume of the heating chamber is reduced due to the small dosage, it is safer and more convenient in use and transportation, and the cost is relatively low, which has important 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...
