Background technology
How reduce harmful substance in the cigarette smoke by effective means, improve the cigarette quality, be the common topic of being concerned about inside and outside the industry, also be main task and the focus of industry tackling of key scientific and technical problems always, and this also is simultaneously that I cross the focal issue that must face and solve in the cigarette evolution.Each tobacco research institution is devoted to the research of this work always and has obtained gratifying achievement, but still has achievement greatly to can not get using, reason be more the complexity of flue gas system and people to cigarette special suck requirement.
In existing research field, the technical staff has summarized 189 pieces of open source literatures to people such as Paschke in the cigarette, contains 300 multiple additives to the impact research of cigarette smoke character.They find different additive and add concentration the impact of smoke components be there are differences.In most cases, after some additive added with its maximum addition in commercial cigarettes or excess (one addition all is the ppm level), some smoke components had and increases or reduce.
But the design of cigarette also can exist the discharging on flue gas to exist very large impact, therefore, science is differentiated the Cigarette design indexs such as cigarette paper additive consumption, cigarette paper parameter, filter stick pressure drop, swollen stem ginseng proportioning exactly to the influence degree of flue gas composition burst size amount, to judging lowering harm and decreasing coking additive effect, improve the cigarette product quality safety and have important practical significance.
About the Cigarette design indexs such as additive amount, cigarette paper parameter, filter stick pressure drop in the cigarette paper on the impact of flue gas composition burst size amount, at existing many researchs reports in the past, and have the researcher attempt setting up the Cigarette design index parameter is adjusted and the flue gas composition burst size between regression equation.But most of research mainly is confined to the effect that the single index adjustment changes the conventional component of flue gas (tar, nicotine, phenol), only there is small part to research and analyse the Cigarette design parameter to 7 kinds of impacts that mainly contain the pest burst size of flue gas, or studies the synergistic effect of many indexs.The conspicuousness of present many correlative studys infers it all is by obtaining with the simple, intuitive comparison that contrasts cigarette, can not be with additive amount, cigarette paper parameter, filter stick pressure drop in the cigarette paper, the Cigarette design indexs such as swollen stem ginseng proportioning change the fluctuation that impact and the experimental error of Chemical Components in Cigarette Smoke are brought to be distinguished, and has affected the accurate judgement of additive lowering harm and decreasing coking effect.Up to now, research about many indexs synergistic action effect, but there is repugnance in the analysis of its indivedual index action effects with the conclusion of other research, therefore differentiate additive amount, cigarette paper parameter, filter stick pressure drop in the cigarette paper according to analysis result, swollen stem ginseng proportioning is to the feasible way that do not have of the conventional fume indication influence degree of cigarette, and then seriously influence Cigarette design, make the design of cigarette can't well reach the lowering harm and decreasing coking effect.

Comparison to its predicted value of the designed cigarette of foundation the present invention and actual value
Use the cigarette material design parameter under the table 6 ISO suction mode to the interpretation of result of flue gas nuisance burst size prediction
Use each regression equation predicting the outcome by cigarette material coaptation flue gas composition burst size, less with the lower deviation that obtains to detect data of ISO suction mode, show this regression equation ideal that predicts the outcome, comparatively accurate to the correlation analysis of cigarette material factor: it is 7.6% that the relative deviation mean value of phenol index is lower than 8%().
The cigarette material parameter is as follows on the impact of flue gas phenol burst size: 1. air permeance for cigarette paper (b2) has certain influence to flue gas phenol burst size (B), but different for the effect under ISO pattern, different tipping paper air permeability (b3) condition.2. under the ISO pattern, improve tipping paper air permeability design load (b3), can effectively reduce the B value.3. only when tipping paper paper air permeability lower (b3=150CU), reduce forming paper air permeability (b4) just Pyrogentisinic Acid's burst size obvious reducing effect is arranged.4. improve filter stick pressure drop (b5) and be conducive to reduce the phenol burst size, but effect is not obvious on the contrary when air permeance for cigarette paper b3=300CU.5. improve other pipe tobacco ginseng dosage (b6), also can effectively reduce the B value, but its effect will weaken when tipping paper air permeability height (b3=450CU).
Therefore, the design of low phenol burst size cigarette is, when phenol detected value and the desired value of new design model cigarette are not inconsistent (being higher than desired value), can realize by following Cigarette design parameter adjustment the decline of model value: 1. reduce air permeance for cigarette paper (b2) design load, improve tipping paper air permeability (b3), when b3=150CU, reduce forming paper air permeability (b4), when b3=150CU or 450CU, improve filter stick pressure drop (b5), when b3=150CU or 300CU, improve other pipe tobacco ginseng dosage (b6).2. under the ISO pattern, the relevance size of different materials parameter and flue gas nuisance burst size is, b3 (+)〉b6 (+, b3=150CU or 300CU)〉b2 (-)〉b5 (+, b3=150CU or 450CU)〉and b4 (, b3=150CU)〉and b1 (+).
