Cigarette molecular sieve and preparation method thereof

Abstract

The invention discloses a cigarette molecular sieve. The cigarette molecular sieve comprises, by weight, 50-80 parts of pelelith, 20-50 parts of clay, 10-30 parts of ox bone and 5-10 parts of a pore forming agent. A preparation technology includes the steps that the raw materials are obtained according to the proportion of the formula and subjected to impurity removal, crushed, dried, sieved and placed in a rounding machine for rounding, the mixture is cooled after being fired in an electric kiln, and the cigarette molecular sieve is obtained. Rounded grains of the prepared cigarette molecularsieve can effectively retain moisture, the mesh number of the rounded grains is 100,000-600,000 per square centimeter, and the water storage amount of each kilogram of round grains is 5-35%. The round grains are placed in a filter tip, and lead, mercury, arsenic and other harmful substances in cigarettes can be effectively removed through the action of a molecular sieve weak magnetic field; besides, the taste of the cigarettes is more sweet, and the cigarettes have mellow and full fragrance and lasting and comfortable aftertaste.

Description

technical field [0001] The invention relates to a molecular sieve used for cigarette filters, in particular to a cigarette molecular sieve and a preparation method thereof. Background technique [0002] Tobacco is an annual herbaceous plant of the family Solanaceae. Tobacco leaves contain a variety of harmful metal elements, such as lead, mercury, and arsenic. An important source of heavy metals contained in tobacco leaves is the soil on which it lives. Irrigation of farmland with sewage, improper use of pesticides, use of leaded gasoline, and harmful gases emitted by factories will all bring heavy metal pollution. Heavy metals cannot be degraded, they can only migrate. Various pollutions caused by industry increase the content of heavy metals in the soil, and these heavy metals are attached to tobacco, with the highest content in tobacco roots, followed by tobacco leaves. On the other hand, changes in geology itself will also cause changes in the content of heavy metals i...

Problems solved by technology

[0004] Although the scientific research and technology for producing cigarettes at home and abroad are constantly developing, they have not been able to achieve the desired effect on filtering harmful chemical components in cigarettes.
