Description
Technical field
The invention belongs to technical field of cigarettes, it is related to a kind of analysis method of Contents of Main Components in cigarette smoke.
Background technique
Accelerate the desin speed of product from the fifties in last century in order to improve the quality of cigarette product, optimizes the body of product
It tests, has carried out a large amount of correlative study both at home and abroad.External cigarette enterprise is started with from the physical chemistry rule of the primary mostly, thin
Breathe freely rule, filter stick filter capacity, the combustion mechanism of cigarette etc. of point field such as cigarette paper has carried out correlative study, forms pair
The whole understanding of cigarette burning filtration mechanism;Domestic research is generally basede on statistical test, analyzes some specific auxiliary materials, rolls
The combination of parameter reaches the forecast function of certain main flume.But since the factor for influencing cigarette smoke is too many, both
The combustion law of entire cigarette an entirety is not combined into, also without forming the analysis method based on cigarette population parameter.
Specifically, cigarette smoke composition and its content are by pipe tobacco component, cigarette structure, cigarette material parameter, burning item
The joint effect of the factors such as part is related to leaf tobacco production, pipe tobacco processing, multiple links such as roll equipment, product design.For standard
Really prediction cigarette mainstream flue gas, reaches the target of Cigarette design, a large amount of research work has been done in industry.
CN105628646 discloses a kind of online tar prediction of cigarette and method for early warning, this method utilize infrared light collection pipe tobacco ingredient,

Influence is more significant, and measurement accuracy deviation is larger in data procedures.CN106108107 disclose it is a kind of based on cigarette structure with
The modeled design method of the total ventilation rate of the cigarette of physical parameter, filter ventilation rates and resistance to suction with cigarette structure characteristic parameter and
Cigarette physical property characteristic parameter is variable, using the total ventilation rate of cigarette, filter ventilation rates and resistance to suction as objective function, by adjusting
Cigarette structure and physical parameter obtain a kind of optimization method for meeting Cigarette design requirement.But this method only obtains cigarette ventilation
Rate and resistance to suction can not study the content of cigarette smoke main component deeper into ground.
