Embodiment 1

[0042] Use Mg 6 Al 2 (OH) 16 CO 3 4H 2 O represents the hydrotalcite. By pulverizing the hydrotalcite for particle classification, the particle diameter was adjusted to 250-500 μm. Using this hydrotalcite to make as figure 1 Filter 1 shown. That is, the hydrotalcite 3 is filled in the gaps provided in the two acetate filter parts 2 and 2 formed by winding the paper respectively, and the cigarette is rolled with the wrapping paper 4 at the same time, thereby manufacturing the filter 1 of the filter section-gap-filter section structure .

[0043] In order to compare with other adsorbents, activated carbon, high specific surface area carbon, alkali metal salt impregnated activated carbon, amine impregnated activated carbon, activated alumina, magnesium oxide, aluminum oxide, magnesium silicate, zinc oxide, silica gel, zeolite, Fuhr Marin uses building material pulp, gas chromatography (GC) column filter section or water-absorbent resin to manufacture and figure 1 Filter ...

Embodiment 2

[0061] Using hydrotalcite as an adsorbent or activated carbon, which is the most common cigarette adsorbent, as an adsorbent, the removal rate of vapor phase components in mainstream cigarettes was obtained.

[0062] Prepare hydrotalcite or active carbon of particle diameter 250-500 μ m in the same manner as embodiment 1, fill with the filling amount of 50 mg respectively, thereby manufacture and figure 1 Same filter. Tobacco with a tar content of 12 mg was attached to the filter to manufacture test cigarettes.

[0063] control Figure 4 as well as Figure 5 , and a method for measuring the removal rate of vapor phase components in mainstream cigarettes will be described.

[0064] Figure 4 is a schematic illustration of the absorption process for vapor phase components. Such as Figure 4 As shown, the cigarette 10 is mounted on the automatic smoking machine 17, the cigarette 10 is automatically smoked under the standard smoking conditions specified by ISO, the particle ...

Embodiment 3

[0071] when for example figure 1 When hydrotalcite is used in the cigarette filter according to the embodiment, it is necessary to appropriately adjust the size of the hydrotalcite in order to control ventilation resistance and tar / nicotine emission.

[0072] If hydrotalcite is granulated, samples with different fineness can be prepared. At this time, the samples were differentiated according to the average particle diameter. exist Figure 7A In , three kinds of samples having an average particle diameter of 250 μm, 500 μm, and 800 μm are shown.

[0073] Next, using hydrotalcite particles with different average particle diameters to produce figure 1 shape filter. For comparison, charcoal was used to manufacture equivalents with figure 1 The form of the filter of the product.

[0074] Check the ventilation resistance of these filters at an inspiratory flow rate of 1050mL / min. Among them, remove the figure 1 The ventilation resistance generated by the 2 acetic acid filte...

Abstract

A smoking filter containing a hydrotalcite compound having a layered structure wherein a large number of metal hydroxide octahedral layers are laminated on each other. Using this smoking filter, formaldehyde in the main smoke can be selectively eliminated.

Description

[0001] This application is a divisional application of the Chinese invention application "cigarette filter tip and tobacco products" with the filing date of January 7, 2003 and the application number of 03801974.4. technical field [0002] The present invention relates to cigarette filters and cigarette products. Background technique [0003] Various chemical constituents are present in the mainstream smoke absorbed by the smoker when smoking a cigarette product. The lower aldehydes represented by formaldehyde in these chemical components are difficult to be absorbed and removed by ordinary cigarette filters. Therefore, there is a need to remove aldehydes from mainstream smoke. [0004] In the past, in order to remove formaldehyde in mainstream smoke, filters were generally used to add activated carbon as an adsorbent. In addition to this, various adsorbents have also been tried. [0005] However, the previously used adsorbents adsorb not only formaldehyde but also other ...
