Embodiment 1

[0021] A method for preparing a filamentous carbonaceous heat source material for tobacco, the steps of which are as follows:

[0022] 1) Mix 1g of sodium alginate with 20g of carbon powder (100 mesh) and 100g of water, stir to form a jelly;

[0023] 2) extruding the jelly into a silk thread with a diameter of 1mm, and fully contacting the thread with a citric acid solution with a pH value of 1 (the contact time between the thread and the acid solution is at least 1 minute) to obtain a cured product;

[0024] 3) Rinse and dry the cured product to make the water content reach 10%, and obtain the filamentous carbonaceous heat source material for tobacco.

Embodiment 2

[0026] A method for preparing a filamentous carbonaceous heat source material for tobacco, the steps of which are as follows:

[0027] 1) Mix 1g of ammonium alginate with 5g of carbon powder (100 mesh), 0.4g of graphite powder and 60g of water, stir to form a jelly;

[0028] 2) extruding the jelly into a silk thread with a diameter of 3mm, and fully contacting the thread with an acetic acid solution with a pH value of 1 to obtain a cured product;

[0029] 3) Rinse and dry the cured product to make the water content reach 20%, and obtain the filamentous carbonaceous heat source material for tobacco.

Embodiment 3

[0031] A method for preparing a filamentous carbonaceous heat source material for tobacco, the steps of which are as follows:

[0032] 1) Mix 1g sodium alginate with 45g carbon powder (100 mesh), 0.1g CaCO 3 Mix with 100g of water, stir to form a jelly;

[0033] 2) extruding the jelly into a sheet with a diameter of 2 mm, fully contacting the silk thread with 99% sulfuric acid solution to obtain a cured product;

[0034] 3) Rinse and dry the cured product to make the water content reach 15%, and obtain the filamentous carbonaceous heat source material for tobacco.

Abstract

The invention discloses a method for preparing a threadlike carbon heat source material for cigarettes by using acid, which comprises the following steps: mixing sodium alginate or ammonium alginate or potassium alginate with carbon powder and water, and stirring into a jelly, wherein the mass ratio of the sodium alginate or ammonium alginate or potassium alginate to the carbon powder is 1:(5-45); extruding the jelly into a thread, and sufficiently contacting the thread with an acidic solution with the pH value of at most 3 to obtain a condensate; and rinsing the condensate, and drying until the water content reaches 10-20%, thereby obtaining the threadlike carbon heat source material for cigarettes. The invention lowers the hazard caused by glass fibers sucked into the human body, enhances the combustibility of the carbon heat source, and has the characteristics of simple method, short production cycle, low cost and the like.

Description

technical field [0001] The invention belongs to the field of cigarettes, and in particular relates to a method for using acid to prepare filamentary carbonaceous heat source materials for cigarettes used in low-temperature cigarettes. Background technique [0002] Studies have shown that nicotine and most tobacco flavor components can be transferred to smoke at lower temperatures (300-500°C). If the temperature of the cigarette is lowered to below 600°C (the ignition point of tobacco is about 700°C), various harmful components of the smoke can be greatly reduced, while the aroma components are relatively less affected. Therefore, a cigarette that uses a carbonaceous heat source for dry distillation of tobacco components was invented. Among them, the carbonaceous heat source of R.J. Reynolds Tobacco’s Eclipse cigarette uses glass fiber wrapped carbon rods. However, the carbon rods are formed by extrusion. , the interior is dense, and in order to form hot air flow, the outer ...
