Description

Aspiration resistance is an important physical performance parameter strictly controlled by cigarette industrial enterprises. It is not only closely related to consumers' smoking experience, but also affects the release of mainstream smoke such as tar, smoke nicotine, and smoke carbon monoxide.

GB/T 22838.5-2009 defines the resistance to draw as: "The cigarette is sealed in the measuring device, the insertion depth of the output end is 9mm, and the flow rate at the output end is maintained at 17.5mL/s under the standard conditions of GB/T 16447. applied negative pressure". Among them, the relative humidity referred to by the above "standard conditions" is 60%, and the atmospheric pressure is 10133Pa. In the actual measurement process, it is difficult to strictly stabilize the humidity and atmospheric pressure within the values of the standard conditions, and a certain degree of fluctuation usually occurs.

The drawing resistance of existing cigarettes is measured by a comprehensive test bench for physical properties of cigarettes and filter rods. In order to reduce the influence of humidity and atmospheric pressure on the measurement accuracy of cigarette draw resistance, the comprehensive test bench was first calibrated with the standard rod of draw resistance, and then the cigarette samples were tested by the comprehensive test bench. The comprehensive test bench for the physical properties of cigarettes and filter rods is generally stored in the physical testing laboratory and the wrapping workshop. The laboratory humidity and atmospheric pressure are not the same as the humidity and atmospheric pressure in the wrapping workshop. . Since the humidity and atmospheric pressure of the cigarette samples are inconsistent with the humidity and atmospheric pressure of the draw resistance standard rod calibration, the use of the draw resistance standard rod for calibration cannot effectively eliminate the influence of humidity and atmospheric pressure on the accuracy of the cigarette draw resistance measurement.

Therefore, how to provide a method that can effectively eliminate the influence of humidity and atmospheric pressure on the measurement accuracy of cigarette draw resistance has become an urgent technical problem to be solved in the art.
