Description
Technical field
The present invention relates to determine in a kind of tobacco business the method for cigarette filter tip paper permeating degree.
Background technology
In recent years, along with the growing interest of society to " smoking is with healthy " problem, people are more and more higher to the requirement that cigarette product is sucked security, country has also put into effect corresponding measure emission of harmful substances quantity such as the tar of cigarette, nicotine, CO has been proposed strict restriction, and meaning from now on will be more and more stricter to the restriction of tobacco product.
Filter tip ventilation dilution technology is a kind of important means of cigarette lowering harm and decreasing coking, and it can make, and most harmful substances are effectively reduced in the cigarette smoke, and is particularly particularly evident for the higher gas phase composition of diffusion coefficient (as CO, NH3, HCN) effect.Because cigarette new national standard " GB 5606-2005 cigarette " proposes clear and definite control requirement to the discharging of CO in smoke of cigarettes, will be applied on a large scale as the filter tip ventilation dilution technology that reduces the effective measures of CO.
The action principle of cigarette filter ventilation dilution can be divided into the following aspects: (1) when suction air thus passage directly enter main flume, change the stream condition of filter segment, reach the purpose of dilution flue gas; (2) ventilation dilution changes the fired state of cigarette, and the air velocity of the burning awl of flowing through is reduced, and burning awl oxygen-supplying amount reduces composition and the quantity that has changed product; (3) ventilate to causing burning around the awl and to enter the air-flow velocity that cigarette props up and reduce, having changed the thermograde of pyrolysis distillation zone, burning awl back; (4) flue gas aerosol leaves the red-hot district cigarette of flowing through and props up low-temperature space, and it continues to be subjected to the influence that filter tip ventilates, and supposes that the flue gas total amount of every mouthful of suction is constant, and the flue gas flow rate and the degree of ventilation of air vent Upstream section reduce pro rata.The flue gas flow rate reduction causes the cigarette paper pressure drop to reduce, and causes by cigarette paper to enter the air minimizing that cigarette props up.The more important thing is that the time lengthening that flue gas stops makes more low-molecular-weight gas such as CO diffusion smoke prop up, so ventilation dilution all changes condensation, filtration, diffusion, the diluting effect of cigarette low-temperature space to some extent in cigarette props up.
In a word, the variation that the filter tip ventilation dilution brings whole cigarette is not only the dilution flue gas, it be many-sided, be very complicated, therefore to seek out a stable product quality, the filter tip dilution rate of cigarette accurately controlled be very important.
At present, the filter tip dilution rate of cigarette generally is to be (the cigarette plug paper air permeability is constant) that the hole drilling ventilation degree of yew paper is controlled by tipping paper used on it, be subjected to simultaneously the influence of nozzle rod sucting resistance and factors such as length, air permeance for cigarette paper and pipe tobacco characteristic again, be the yew paper and the cigarette plug paper of same air permeability, for different cigarette, dilution rate also is discrepant, also there is not a kind of comparatively easy passing method that cigarette filter tip paper permeating degree is carried out accurate method for measuring to this, so that its dilution rate is controlled.
Summary of the invention
