Embodiment 1

[0025] Take 1kg of micro-powder silica gel, crush it into 120-140 mesh powder, dry it at 50°C until the water content is 8-10%, and then place the prepared micro-powder silica gel powder in a Midi Glatt fluidized bed for granulation. The fluidizing pressure is 0.12 Bar, and the air temperature is 50°C and dried for 5 minutes; then, the sodium carboxymethyl starch is prepared with distilled water to make a binder solution with a concentration of 10%, which is sprayed by the top spray method, and the fluidizing pressure is 0.2 Bar, air temperature is 60°C, spray pressure is 0.08Bar, spray rate is 12g / min, binder solution dosage is 200g; after the adhesive is applied, set the fluidizing pressure to 0.12Bar, and the airflow temperature is 50°C Drying at high temperature for 5 minutes can obtain micropowder silica gel porous particles for cigarette filter rods with a moisture content of 10-12% and a particle size distribution of 20-60 mesh.

Embodiment 2

[0027] Take 500g of micro-powder silica gel, crush it into 160-200 mesh powder, dry it at 60°C until the water content is 8-10%, put the prepared micro-powder silica gel powder in a Midi Glatt fluidized bed for granulation, and the fluidized bed flow Dry at 0.15 Bar and air temperature of 60°C for 3 minutes; then prepare sodium carboxymethyl starch with distilled water to make an 8% binder solution and spray it with a top spray method with a fluidizing pressure of 0.2 Bar , The air flow temperature is 80°C, the spray pressure is 0.12Bar, the spray rate is 15g / min, and the amount of adhesive solution is 100g; after the adhesive is applied, set the fluidizing pressure to 0.15Bar, and the air flow temperature is 60°C to dry Within 3 minutes, micropowder silica gel porous particles for cigarette filter rods with a water content of 10-12% and a particle size distribution of 20-60 meshes are obtained.

Embodiment 3

[0029] Take 300g of micro-powder silica gel, crush it into 120-150 mesh powder, dry it at 50°C until the water content is 8-10%, put the prepared micro-powder silica gel powder in a Midi Glatt fluidized bed for granulation, firstly The fluidizing pressure is 0.15Bar, and the air temperature is 55°C and dried for 5 minutes; then, the sodium carboxymethyl starch is prepared with distilled water to make a binder solution with a concentration of 5%, and it is sprayed by the top spray method, and the fluidizing pressure is 0.18 Bar, airflow temperature 70°C, spray pressure 0.08Bar, spray rate 12g / min, adhesive solution dosage 50g; after the adhesive is applied, set fluidizing pressure 0.15Bar, airflow temperature 55°C After drying for 5 minutes, micropowder silica gel porous particles for cigarette filter rods with a water content of 10-12% and a particle size distribution of 20-60 meshes are obtained.

Abstract

The invention discloses an aerosol porous particle and application in a cigarette. The aerosol porous particle is prepared by the fluidized bed top shower process taking aerosol powder of 120-300 meshes as the raw material and sodium carboxymethyl starch as an adhesive. The particle has a coarse surface and relatively high specific surface area, can obviously increase the effective contact area between a particular material and the smoke of the cigarette, and is able to selectively absorb hydrogen cyanide in the smoke; and the aerosol porous particle has both functions of reducing harm and lowering the irritation of the smoke of the cigarette. The production process of the aerosol porous particle is simple, the operability and normativity are high, the raw material is easily available, the cost is low, the industrial production can be conveniently realized, and a good application prospect is brought.

Description

technical field [0001] The invention belongs to the technical field of cigarette materials, and in particular relates to a micropowder silica gel porous particle capable of absorbing hydrogen cyanide in cigarette smoke. At the same time, the invention also relates to the application of the porous particle in cigarette processing. Background technique [0002] Silica gel is a typical highly active adsorption material with a molecular formula of mSiO2 nH2O. It is non-toxic, odorless, rich in pore structure and high specific surface area, which makes it have excellent adsorption performance. It is widely used in the preparation of various gas adsorbents, Catalyst carriers, environmental purification functional materials and chromatographic column packings are internationally recognized green products. Because micropowder silica gel has the characteristics of small particle size, large pore volume and strong surface activity, it can be used as a stabilizer and filter agent in t...
