Carry out flue gas analysis according to National Standard of the People's Republic of China's " cigarette conventional analysis smoking machine measures TPM and tar GB/T19609-2004 ", measure the content of TPM, tar, nicotine, CO in flue gas.
Below respectively the moisture holding capacity of hydrous material in the present invention, hydrous material release conditions at different temperatures, the moisture of cigarette main stream smoke burst size situation of adding hydrous material and aesthetic quality's situation are verified.
1, the moisture holding capacity of hydrous material
For hydrous material (also known as water storage material), its moisture holding capacity is concerning most important its performance.Moisture holding capacity mainly comprises two aspects, and one is moisture storage capacity, and one is the stability of storage capacity.These two aspects is all in close relations with the gap structure of porous material.In general, the specific area of adsorbent is larger, and it is larger to the adsorbance of adsorbate.Micropore is abundanter, and it is larger to the adsorbance of adsorbate.Adsorbent is zeolite, and adsorbate is water.In order to obtain high moisture storage capacity, require that zeolitic material needs to possess larger specific area.As seen from Table 1, the specific area of zeolitic material is 115.8298m
2/ g, has higher specific area, can adsorb more moisture.According to the assay method of foregoing aqueous material moisture content, record the hydrous material prepared by zeolite in the present invention, its moisture content reaches about 52.44 ± 0.20%, and, no matter be sample preparation (5g zeolite) or amplificationization preparation (250g zeolite), the moisture content of hydrous material all reaches 50%.This illustrates that 1.0g moisture is loaded in the reducible absorption of 1.0g zeolite.
For the stability of hydrous material water storage, relevant with the average pore size of zeolitic material.Usually, the average pore size of adsorbent is larger, and it is more weak to the suction-operated of adsorbate, and out, namely stability is poorer for the easier desorption of adsorbent; The average pore size of adsorbent is less, and it is larger to the active force of adsorbate, and need higher energy that adsorbate just can be made at adsorbent surface desorption, namely stability is stronger.So the aperture structure of adsorbent is to the suction-operated important of adsorbate.As can be seen from Table 2, after hydrous material is placed 1 week, moisture only loses 0.48%, and when placement is after 15 weeks, moisture loss is also no more than 2.5%, and the moisture content of hydrous material still can remain on 50%.This illustrates that the moisture holding capacity of hydrous material is comparatively stable, also illustrates that zeolite has stronger active force to hydrone.
The pore structure parameter of table 1 zeolitic material
Note: BET model is the material complete opening specific area calculated based on multilayer absorption hypothesis; The aperture that BJH model calculates is mesopore pore size, and its scope is at 1.7-50nm; The aperture that HK model calculates is micropore size, its range L EssT.LTssT.LT 1.7nm.
The time dependent situation of table 2 hydrous material of the present invention water content
| Time (week) | Moisture content | Moisture loss |
| 0 | 52.44% | -- |
| 1 | 51.96% | 0.48% |
| 2 | 51.37% | 1.07% |
| 3 | 51.90% | 0.54% |
| 9 | 50.81% | 1.63% |
| 15 | 50.02% | 2.42% |
For different application purposes, also different to the requirement of adsorbent.From the storage of material, require that zeolite is more strong better to the active force of hydrone, be convenient to long-time storage; From the release of hydrone, require that zeolite is more weak better to the active force of hydrone, hydrone is facilitated to discharge from hydrous material, this just requires that the active force of zeolite to hydrone needs a balance, the stability that hydrous material keeps certain can be made, meanwhile, hydrone can be allowed again to discharge in cigarette smoking process.
2, hydrous material release conditions at different temperatures
It is 8-10min that general cigarette burns and sucks process, burns and sucks filter tip place temperature in process and can rise to 45 DEG C ~ 50 DEG C from room temperature.So by hydrous material dry 10min at the temperature of 35 DEG C, 40 DEG C, 45 DEG C respectively, that simulates cigarette burns and sucks process, investigates the release conditions of moisture in hydrous material.As seen from Table 3, along with the rising of baking temperature, in hydrous material, moisture release rate raises gradually, and when baking temperature is 55 DEG C, moisture release rate reaches 21.90%.As can be seen from Figure 1, along with baking temperature is elevated to 45 DEG C from 35 DEG C, moisture release rate rises comparatively mild, and when baking temperature is elevated to 50 DEG C from 45 DEG C, moisture release rate has a significantly sudden change, reach 7%, this is just consistent with filter tip place temperature in cigarette burning process, illustrates that the moisture in hydrous material prepared in the present invention can discharge rapidly in cigarette burning process.
As can be seen from hydrous material moisture holding capacity stability data and its at different temperatures moisture release data: zeolite possesses good adsorption capacity to hydrone, hydrone can be allowed again to discharge at a certain temperature simultaneously, it have found good balance between adsorption capacity and releasability, and this shows that this zeolitic material of the present invention can be applied in cigarette filter.
Table 3 hydrous material moisture release conditions at different temperatures
| Temperature (DEG C) | Quality (g) before dry | Quality (g) after dry | Before and after dry (g) of poor quality | Moisture release rate |
| 35.0 | 2.011 | 1.821 | 0.190 | 9.45% |
| 40.0 | 2.009 | 1.798 | 0.211 | 10.50% |
| 45.0 | 2.007 | 1.773 | 0.234 | 11.66% |
| 50.0 | 2.006 | 1.632 | 0.374 | 18.64% |
| 55.0 | 2.005 | 1.566 | 0.439 | 21.90% |
3, moisture of cigarette main stream smoke burst size situation and aesthetic quality's situation of hydrous material is added
In order to investigate the effect of hydrous material of the present invention in cigarette further, in cigarette, adding the hydrous material of different amount respectively, and test the change of its main flume conventional ingredient.As shown in table 4, when adding 5.0mg/cig hydrous material, in main flume, moisture is 2.00mg/cig, increases by 10.50% than blank; When adding 10.0mg/cig hydrous material, in main flume, moisture is 2.15mg/cig, increases by 18.78% than blank; When in cigarette, the amount of hydrous material increases to 15.0mg/cig, in main flume, moisture is increased to 2.17mg/cig, increases by 19.89% than blank.Can find out from experimental result, along with the increase of hydrous material addition in cigarette, in main flume, moisture obviously increases, and other flue gas conventional ingredients, comprise tar, nicotine, carbon monoxide etc., without significant change.This illustrates, adds hydrous material, can effectively improve moisture in main flume, and have no significant effect other conventional ingredients in cigarette.It is to be noted, when hydrous material addition is increased to 15.0mg/cig from 10.0mg/cig, in main flume, moisture only increases 0.02mg/cig, change not too obvious, its reason may be the increase along with hydrous material, hydrous material is piled up comparatively tight each other, plugs the surface void of partially aqueous material, causes portion of water to discharge.
Carry out sensory quality assessment to adding the cigarette of hydrous material: compare with blank cigarette, with the addition of the cigarette of hydrous material, its soft aroma and, concentration is slightly light, stimulates little, and flue gas is more fine and smooth, and pleasant impression is comparatively comfortable.This illustrates, adds hydrous material, by improving the moisture of cigarette mainstream flue gas, can reduce the excitant of cigarette smoke, improving the sucking quality of cigarette.
The cigarette mainstream flue gas conventional ingredient data of table 4 different materials addition
As can be seen from above embodiment and compliance test result data, the present invention utilizes the loose structure of zeolite and larger specific area thereof, is loaded, prepare the hydrous material that moisture content reaches more than 50% by absorption.This hydrous material has higher moisture holding capacity, and after placing 15 weeks, its moisture loss does not surpass 2.5%.Burnt and sucked the variations in temperature at filter tip place in process by simulation cigarette, prove that in hydrous material, moisture can discharge rapidly in smoking process.Show that this hydrous material had both met storage stability requirement, can burn and suck in process at cigarette again and moisture is discharged.Analyzed and sensory evaluation analysis by main flume conventional ingredient, can find out: after with the addition of hydrous material, in main flume, moisture can increase by 19.89%, and flue gas excitant lowers, and pleasant impression is comparatively comfortable, improves the sucking quality of cigarette.
