Method for preparing threadlike carbon heat source material for cigarettes by using acid

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 ...

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
