Method for rapid detection of ventilation performance of filter rods for high air permeability formed cigarettes

Abstract

The invention discloses a method for fast detecting venting performance of filter tip of a cigarette made of high air permeability forming paper. The method comprises the following steps of: (1) determining closed suction resistance, circumference, length, hardness index processing parameters of the filter tip; (2) manufacturing test filter tip samples by using forming paper with different air permeability indexes; (3) testing opening suction resistance values of different filter samples; (4) making an alignment chart for the air permeability of the forming paper through the opening suction resistance obtained in step (2); (5) performing opening suction resistance testing on a to-be-tested filter tip, if the opening suction resistance value is close to a straight line, determining that the filter tip is normal in quality, if the opening suction resistance value is above the straight line, determining that the filter tip is bad in venting performance, and finding the reason from the aspects that whether the specification of the high air permeability forming paper is misused, and whether the glue in the filter tip is overflow; and if the opening suction resistance value is below the straight line, determining that the venting performance of the filter tip has a passed the design target, and finding the reason from the aspect that whether the specification of the high air permeability forming paper is misused.

Description

technical field

[0001] The invention relates to a method for detecting the ventilation performance of a filter tip rod, in particular to a method for rapidly detecting the ventilation performance of a filter tip rod for high air permeability formed cigarettes. Background technique

[0002] With the continuous improvement of people's consumption concept and health awareness, as well as the signing and implementation of the tobacco control framework treaty, the tobacco industry has been focusing on "reducing tar and harm" as a key topic in recent years. In order to effectively reduce tar and ensure the taste of cigarettes, more and more low-tar cigarette products use filter ventilation technology. The stability of cigarette filter ventilation is the key to ensure the design of low-tar cigarettes, and the ventilation performance of filter rods is the most important factor affecting the ventilation of cigarette filters. At present, there is no way to test the ventilation perfor...
