Method for using ethanol to prepare sheet carbonaceous heat sources for cigarettes

Abstract

The invention discloses a method for using ethanol to prepare sheet carbonaceous heat sources for cigarettes. The method comprises the following steps: mixing sodium alginate or ammonium alginate or potassium alginate with carbon powder and water, and stirring the mixture into a jelly-like substance, wherein the weight ratio of the sodium alginate or the ammonium alginate or the potassium alginate to carbon powder is 1:(5-45); then extruding the jelly-like substance into thin sheets, and intensively mixing the thin sheets with ethanol with a mass concentration of more than or equal to 66% to obtain a solidified substance; and rinsing and drying the solidified substance until the moisture content of the solidified substance reaches 10-20% to obtain the sheet carbonaceous heat sources for cigarettes. The method provided by the invention not only reduces the harm caused by inhalation of glass fiber into a human body, but also improves the flammability of carbonaceous heat sources, and has the characteristics of simple method, short production period, 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 ethanol to prepare sheet-shaped 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 ou...

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 layer needs to be wrapped with breathable glass fiber. Some studies believe that even if such particles can be trapped by the filter material, they will inevitably be adsorbed on the filter during packaging and other processes, resulting in inhalation and harm. Healthy, dense carbon rods are also harder to ignite than thinner carbon filaments
