Embodiment 1

[0022] A method for preparing a sheet-shaped carbonaceous heat source material for cigarettes, the steps of which are as follows:

[0023] 1) Mix 1g of sodium alginate with 20g of carbon powder (100 mesh) and 100g of water, stir to form a jelly;

[0024] 2) Extrude the jelly into a thin sheet with a thickness of 2.5mm with counter-rotating rollers, and mix the thin sheet with saturated CaCl 2 The solution is in full contact (the contact time between the sheet and the calcium solution is at least 1 minute), and the cured product is obtained;

[0025] 3) Rinse and dry the cured product to make the water content reach 10%, and obtain the sheet-shaped carbonaceous heat source material for cigarettes.

Embodiment 2

[0027] A method for preparing a sheet-shaped carbonaceous heat source material for cigarettes, the steps of which are as follows:

[0028] 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;

[0029] 2) Squeeze the jelly into a thin sheet with a thickness of 2mm with counter-rotating rollers, and mix the thin sheet with 10% CaCl 2 The solution is fully contacted to obtain a cured product;

[0030] 3) Rinse and dry the cured product to make the water content reach 20%, and then obtain the sheet-shaped carbonaceous heat source material for cigarettes.

Embodiment 3

[0032] A method for preparing a sheet-shaped carbonaceous heat source material for cigarettes, the steps of which are as follows:

[0033] 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;

[0034] 2) Extrude the jelly into a thin slice with a thickness of 1mm with counter-rotating rollers, and mix the thin slice with 1% CaCl 2 The solution is fully contacted to obtain a cured product;

[0035] 3) Rinse and dry the cured product to make the water content reach 15%, and obtain the sheet-shaped carbonaceous heat source material for cigarettes.

Abstract

The invention discloses a method for preparing cigarette flaky carbonaceous heat source materials by calcium salt. The method includes the steps of mixing sodium alginate, ammonium alginate or potassium alginate with carbon powder and water according to a mass ratio of the sodium alginate, ammonium alginate or potassium alginate to the carbon powder of 1:5-45, stirring to colloids, then extruding the colloid into flakes, and enabling the flakes to fully contact with calcium salt solution to obtain cured substances; and subjecting the cured substances to rinsing and drying to enable moisture content to reach 10-20% so as to obtain the cigarette flaky carbonaceous heat source materials. Harm caused by the fact that fiberglass is inhaled into a human body is reduced, and combustibility of carbonaceous heat sources is improved; and the method has the advantages of simplicity, 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 preparing sheet-shaped carbonaceous heat source materials for cigarettes used in low-temperature cigarettes by using calcium salts. 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...
