Problems solved by technology

However, the problem is that when polylactic acid undergoes glass transition, it will melt or melt and bond. Therefore, the polymer material at the end of the most cooled end that first contacts the smoke will immediately undergo serious adhesion and collapse, blocking the pores and making the smoke Air cannot flow smoothly through the pleated polymer interior, reducing the cooling surface area and resulting in excessively high flue gas temperatures

Embodiment 1

[0086]The commercial cellulose diacetate was wet-ground into powder with an average particle size of 48 microns. Weigh 1 kg of the above ground powder sample, add 1.18 kg of 7.8% hydroxypropyl methylcellulose (HPMC) aqueous solution, and fully stir and mix on a laboratory wet mixer to obtain a wet material. The soft wet material prepared above was subjected to wet extrusion and granulation on an E-50 wet extruder (distribution plate aperture 1.0 mm) to obtain cylindrical bars. The feed speed of the extruder was 23 rpm and the extrusion speed was 26 rpm. The cylindrical bar was spheronized on an S-250 spheronizer to obtain spherical wet granules. The spheronization conditions are as follows: the spheronizer first works at 600rpm for 1.5 minutes, and then works at 500rpm for 3 minutes. The above spherical wet granules were dried at 105-120°C for 5-6 hours to remove moisture to obtain dry active granules (and serve as comparative spherical granules for the flue gas temperature ...

Embodiment 2

[0092] Weigh 1 kilogram of industrial microcrystalline cellulose (produced by Anhui Shanhe Company, the average particle size of the powder is 45 microns), add 1.22 kilograms of 9.1% pregelatinized starch aqueous solution, fully stir and mix on a laboratory wet mixer to obtain a wet material . The soft wet material prepared above was subjected to wet extrusion and granulation on an E-50 wet extruder (distribution plate aperture 1.0 mm) to obtain cylindrical bars. The feed speed of the extruder was 24 rpm and the extrusion speed was 27 rpm. The cylindrical bar was spheronized on an S-250 spheronizer to obtain spherical wet granules. The spheronization conditions are as follows: the spheronizer first works at 650rpm for 2 minutes, and then works at 450rpm for 3 minutes. The spherical wet granules prepared above are dried at a temperature of 105-120° C. for 5-6 hours to remove moisture to obtain dry active granules. The dried inner layer rigid solid spheres were sprayed at the...

The spherical wet granules prepared above are dried at a temperature of 105-120° C. for 5-6 hours to remove moisture to obtain dry active granules. The dried active granules are film-coated with a bottom...

Abstract

The invention belongs to the technical field of cigarette auxiliary materials, and relates to a particle capable of reducing the temperature of mainstream cigarette smoke and a preparation method and application thereof. The particles are inactive particles or active particles or inactive particles of the outer coating layer. For the inactive particles, the thickness of the outer coating layer is 0-0.2 mm, and the outer coating layer accounts for 0-50% of the mass of the whole particle; the active particles, the thickness of the outer coating layer is 0.001-0.2 mm, The film layer accounts for 0.001‑50% of the mass of the entire particle. The inactive particles are those whose adsorption of nicotine in the smoke aerosol is less than 3.0 mg / cm 3 particles; the inactive particles include inorganic particles or organic particles. The preparation method of the invention is simple, easy to be industrialized and industrialized, and the particles are easy to be added to the cigarette filter rod, the surface of the particles is dense, and there is no leakage, and the addition of the particles to the cigarette filter rod can greatly reduce the temperature of cigarette smoke.

Description

technical field [0001] The invention belongs to the technical field of cigarette auxiliary materials, and relates to a particle capable of reducing the temperature of mainstream cigarette smoke and a preparation method and application thereof. Background technique [0002] Cigarettes are a special consumer product whose consumption is to enjoy the smoke by inhaling them. Cigarette smoke refers to a highly concentrated and constantly changing aerosol system produced by the shredded tobacco in the lit cigarette through a complex combustion process. There are two forms of cigarette combustion: one is the combustion during smoking, which is called burning; the other is the burning in the suction gap, which is called smoldering (also known as static combustion). [0003] The smoke sucked from the filter end of the cigarette during smoking is called Main-stream Smoke (MS), and the smoke released from the burning end in the suction gap and diffused directly into the environment th...
