Description
Technical field
The present invention relates to Cigarette design field, particularly relate to the method for adjustment of each Cigarette design parameter in a kind of Cigarette design based on N-nitrosamine burst size.
Background technology
How reduce the harmful substance in cigarette smoke by effective means, improve cigarette quality, be the inside and outside common topic be concerned about of industry, be also main task and the focus of industry tackling of key scientific and technical problems always, this be also simultaneously I to cross in cigarette evolution must in the face of and the focal issue that solves.Each tobacco research institution is devoted to the research of this work always and achieves gratifying achievement, but still has achievement greatly to can not get application, reason be more the complexity of flue gas system and people to cigarette special suck requirement.
In existing research field, technical staff reviews 189 sections of open source literatures to people such as Paschke in cigarette, contains the influence research of 300 multiple additives to cigarette smoke character.They find different additive and add the impact of concentration on smoke components there are differences.In most cases, after some additive adds with its maximum addition in commercial cigarettes or excess (one addition is all ppm level), some smoke components has and increases or reduce.
But the design of cigarette also can exist and there is very large impact to the discharge of flue gas, therefore, science differentiates that the Cigarette design index such as cigarette paper additive consumption, air permeance for cigarette paper, tipping paper air permeability, forming paper air permeability, filter stick pressure drop, expanded cut stem ginseng proportioning is to the influence degree of flue gas composition burst size amount exactly, to judgement lowering harm and decreasing coking additive effect, improve cigarette product quality safety and have important practical significance.
About Cigarette design indexs such as additive amount, air permeance for cigarette paper, filter stick pressure drops in cigarette paper on the impact of flue gas composition burst size amount, report in existing many research in the past, and have researcher to attempt setting up the regression equation between the adjustment of Cigarette design index parameter and flue gas composition burst size.But major part research is mainly limited to the effect that single index adjustment changes flue gas conventional constituents (tar, nicotine, N-nitrosamine), only have small part to research and analyse Cigarette design parameter mainly contains pest burst size impact on flue gas 7 kinds, or the synergistic effect of research multi objective.But it is all obtain by comparing with the simple, intuitive contrasting cigarette that the conspicuousness of current many correlative studys is inferred, can not by additive amount, air permeance for cigarette paper, filter stick pressure drop in cigarette paper, the Cigarette design index changes such as expanded cut stem ginseng proportioning are distinguished the fluctuation that impact and the experimental error of Chemical Components in Cigarette Smoke are brought, and have impact on the accurate judgement of additive lowering harm and decreasing coking effect.And up to now, about the research of multi objective synergistic action effect, there is repugnance in the conclusion that the analysis of its indivedual index action effect is but studied with other, therefore additive amount, air permeance for cigarette paper, filter stick pressure drop in cigarette paper is differentiated according to analysis result, the Cigarette design indexs such as expanded cut stem ginseng proportioning are to the unfeasible way of cigarette smoke components influence degree, and then serious have influence on Cigarette design, make the design of cigarette cannot well reach lowering harm and decreasing coking effect.
Summary of the invention
Goal of the invention of the present invention is the defect overcoming prior art, there is provided a kind of in production cigarette process, effectively can control the N-nitrosamine discharge capacity in flue gas, improve the method for adjustment based on each component in the Cigarette design of N-nitrosamine burst size of Cigarette design efficiency.

-5) × b4 – 8.6666 × b6, wherein C is the discharge capacity of N-nitrosamine, and b2 is air permeance for cigarette paper, and b4 is forming paper air permeability, and b6 is expanded cut stem mixed ratio;
Parameters on the size that N-nitrosamine burst size affects is: tipping paper air permeability > air permeance for cigarette paper > filter stick pressure drop > cigarette paper additive consumption > forming paper air permeability > expands swollen silk mixed ratio;
When repeating step 3) in step 4), also comprise according to N-nitrosamine discharge relational model obtain cigarette paper additive consumption, air permeance for cigarette paper, tipping paper air permeability, forming paper air permeability, filter stick pressure drop and expanded cut stem mixed ratio respectively with the relevance of N-nitrosamine burst size, and regulate the step of described parameter according to this relevance.
2. the method for adjustment of each Cigarette design parameter in the Cigarette design based on N-nitrosamine burst size according to claim 1, it is characterized in that, control method for described parameter is: the parameter of relevance to current use according to parameters and N-nitrosamine burst size regulates, first determine tipping paper air permeability, then increase according to the Cigarette design parameter of each correspondence under different tipping paper air permeability and the relevance formula of N-nitrosamine burst size or reduce the value of parameters.
3. the method for adjustment based on parameters in the Cigarette design of N-nitrosamine burst size according to claim 1, it is characterized in that, when tipping paper air permeability is 150CU, the control method for described parameter is following: improve air permeance for cigarette paper, improve cigarette paper additive consumption or to improve in expanded cut stem mixed ratio one or more combination adjusting method.
4. the method for adjustment based on parameters in the Cigarette design of N-nitrosamine burst size according to claim 1, it is characterized in that, control method for described parameter is, when tipping paper air permeability is 300CU, reduces air permeance for cigarette paper and/or reduces filter stick pressure drop.
5. the method for adjustment based on parameters in the Cigarette design of N-nitrosamine burst size according to claim 1, it is characterized in that, when tipping paper air permeability is 450CU, the control method for described parameter is following: improve air permeance for cigarette paper, improve forming paper air permeability, to improve in expanded cut stem mixed ratio one or more combination adjusting method.
