Formation mainly there are six part: pipe tobacco leading portion (cigarette paper package), pipe tobacco back segment (tipping paper package), leads to cigarette paper part
Wind filter tip front section (being boundary from filter tip and pipe tobacco section contact face to filter tip vent position), ventilation filter tip hindfoot portion
(being boundary from filter tip vent position to filter tip air stream outlet end face) and filter tip divulge information (cheesing techniques or ventilated technology) etc.,
And simply decompose mainly four filter segment, pipe tobacco section, cigarette paper and filter tip ventilation parts.The survey of cigarette each section resistance to suction size
Amount, especially filter segment and pipe tobacco section two parts are to realize the quality tracing of Cigarette Draw Resistance stability (to two resistance to suctions and resistance to suction
The stability origin cause of formation), product design (how resistance to suction design regulated and controled) and throwing and cigarette technique process parameter optimization (such as
What obtains more stable Cigarette Draw Resistance etc.) key technology.
It is globality by the Cigarette Draw Resistance that GB/T 22838.5-2009 standard method is known, if the cigarette measured
Resistance to suction is unstable, and the journey of Cigarette various pieces resistance to suction stability can not be quickly known by the degree of fluctuation of globality resistance to suction
Degree, if it is desired to know four parts, especially filter segment and pipe tobacco section such as filter segment, pipe tobacco section, cigarette paper and filter tip ventilation
Stability (because the processing technology of two parts is entirely different) property of resistance to suction, needs for cigarette to be cut into two sections of progress
It measures respectively, not only measurement period is long, time-consuming and laborious for this method, but will bring the error of test.
