preparation example Construction

[0043] Filtration articles may be prepared according to known methods for preparing similar products.

[0044] According to the required shape, filter products can be made into different shapes, such as cylindrical, cylindrical, ring-shaped, granular, etc., for example, formed into the desired shape by the usual method, such as cigarette filters, gas mask filter cores, etc. . The hydrated aluminosilicate can also be directly used in cigarettes. For example, the hydrated aluminosilicate has a size of more than 325 mesh, and is evenly added to the shredded tobacco at a ratio of 0.01% to 5%, so that the shredded tobacco can be used before or during combustion. In itself becomes a filter product.

[0045] The filtering product of the present invention can be used for removing gas, especially harmful components in cigarette smoke, and achieves satisfactory effects, especially good for removing tobacco-specific nitrosamines, condensed ring aromatic hydrocarbons, free radicals and t...

Embodiment 1

[0083] According to the ratio of 2 mg hydrated aluminosilicate / filter tip, fully mix the hydrated aluminosilicate and ordinary granular activated carbon according to the weight ratio of filter material: activated carbon = 2:15, and then filter the hydrated aluminosilicate according to the cigarette filter production requirements Activated carbon as the material was uniformly dispersed in 700 mg of cellulose acetate used to manufacture the filter to prepare a cigarette filter (composite tip rod, diameter: 7.8 mm, length: 24 mm). The composition of hydrated aluminosilicate is:

[0084] CaO 1.0%

[0085] MgO 2.0%

[0086] Fe 2 o 3 3.0%

[0087] K 2 O 0.5%

[0088] Al 2 o 3 13.0%

[0089] SiO 2 75%

[0090] The hydrated aluminosilicate is in the form of powder, all of which pass through a 20-mesh sieve.

[0091] Remove the filter tip from the commercially available Zhongnanhai brand cigarette of Beijing Cigarette Factory, plug the cigarette filter tip prepared a...

Abstract

The present invention is the application of filtering material containing aluminosilicate hydrate in preparing filtering product for lowering the harmful component content in gas, especially cigarette fume. The filtering product, including filter, gas mask, filtering tip for cigarette, etc contains the filtering materials CaO 1.0-10 wt%, MgO 1.0-15 wt%, Fe2O3 3.0-15 wt%, K2O 0.2-3.0 wt%, Al2O3 8-30 wt% and SiO2 50-86.8 wt% on some carrier.

Description

field of invention [0001] The present invention relates to the application of hydrated aluminosilicate and filter product containing hydrated aluminosilicate; filter products. Background technique [0002] In daily life, people usually come into contact with gaseous media, such as breathing air and so on. However, gases often include various impurities, such as various harmful components, and filtering out these impurities is beneficial to human health. For this, filter articles such as filters or gas masks are used. [0003] In a specific aspect, it has long been found that smoking has adverse health effects: epidemiological surveys and experimental studies have shown that smoking can lead to increased incidence and mortality of various diseases, such as acute and chronic trachea / bronchitis, pneumonia , myocardial infarction, stroke, many cancers including lung cancer, etc. Nicotine has long been thought to be the source of the toxicity of smoking, but it's not the only...
