Description

The invention relates to the tobacco industry and can be used in the manufacture of filters for tobacco products.

A known method of manufacturing a filtering material for a cigarette filter is that the acetate fiber is treated with a plasticizer as used: triethyl acetate, dimethoxyethyl phthalate, megylphthalyl ethyl glycolate, triacetin 1 3.

The main feature of the specified ATP is that expensive organic compounds are used as a plasticizer, which ultimately increases the cost of the filter material.

The closest to the present invention is a method for manufacturing filters for tobacco products, including the alignment of an acetate fiber ribbon, the application of a mixture of plasticizers containing triacetin and a glycol-triethylene glycol C23 compound on the latter.

The use of triacetin and triethyde-25 glycol as plasticizers for the manufacture of filters for tobacco products, entails an increase in their cost, since both plasticizers are high in cost. In addition, similar filters do not sufficiently hold bases, volatile acids, and acrolein, one of the main indicators of tobacco toxicity.

The purpose of the invention is to increase the retention - 5% of the filter capacity and reduce their cost.

To achieve the supplied chain according to the method of manufacturing filters for tobacco products, including aligning the acetate fiber tape, applying the last mixture of plasticizers containing triacetin and the compound glycol, forming the schtrang tape and then cutting it, when glycol compounds are applied from glycol compounds, diethylene glycol is used. ratio with triacetin, amounted to cement 2: 3,

A mixture of plasticizers is applied in an amount of 8-9% by weight of acetate fiber 50%.

The drawing shows a device for implementing the method.

The device contains an apparatus of 1 dp. Ribbon ribbon acetate fiber, napra / 55 equals rolls 2, rolls 3 for straightening the tape in elastic, pneumatic spray 4, chamber 5 for applying plasticizer containing spray nozzles 6 transporting the rolls 7, machine 8 to form shtranga and its subsequent cutting.

example. A tape of acetate fiber from the bale 9 of the extrusion is fed into the apparatus 1 of the preliminary compaction and through the guide rollers 2 to the rollers 3 spreading the tape and pneumatic dispenser 4, after which the tape is directed to the plasticization chamber 5, in which by fine spraying of spray nozzles 6 onto it ts plasticizer. From the plasticizing chamber, with the aid of the conveying rollers 7, the belt is fed to the filing machine 8.

A comparative analysis of fiTs manufactured in a known manner and proposed confirms that the holding capacity of filters with a new type of plasticizer is higher. Retention of bases, volatile acids, acrolein, one of the main indicators of toxicity of tobacco datm, increases.

Spectrophotometric analysis of the absorption of alcohol solutions of substances of the solid-phase tobacco smoke with gas filters with plasticized with triacetin, below the absorption spectrum of the alcohol solution of cigarette smoke with filters plasticized with plasticizer of a new type. This confirms the increase in the retention capacity of fillers treated with a mixture of triacetin and diegylene glycol.

Mathematical processing of experimental ga on the reliability of differences shows that the differences between the absorption spectra in the ultraviolet region are reliable, this confirms the increase in the retention of the components of the solid - liquid phase, which has high carcinogenic activity. Studied parameters-.

Smoking cigarettes with dry and control filters using a technique to determine the response of a smoker when smoking cigarettes in natural conditions. The following smoking parameters are determined: volume and time of hitch, frequency of hardening. The statistical processing of the obtained data shows that the difference between the determined parameters in the experimental and control samples of the cigar tcjymecTBeHHa .STO suggests that, from the point of view of the consumption of filter cigarettes, the replacement of 40% triacetin with diethylene glycol is quite reasonable.

The application of the proposed pharmaceutical industry to

Magnetic oil will allow to get economically: - the penetration of filter cigarettes and the import effect of trnacetin, which is used domestically, is applied to filtering materials, and the use of preplagable industry will allow 2.08 mln. rub / g of filtering material.

in relation to the prototype, 1.85 million rubles. / The purchase of triacetin for management is a fact that can be.
