Description

Method for measuring cigarette resistance humidity and atmospheric pressure compensation
Technical Field
The invention relates to the field of cigarette resistance measurement, in particular to a method for measuring the humidity and atmospheric pressure compensation of cigarette resistance.
Background
The resistance to smoking is an important physical property parameter strictly controlled by cigarette industry enterprises, is closely related to the smoking feeling of consumers, and influences the release amount of main stream smoke such as tar, nicotine, carbon monoxide and the like.
GB/T22838.5-2009 defines the resistance to draw as: "seal the cigarette in the measuring equipment, insert the depth of the output end to 9mm, maintain the flow rate of the output end to 17.5mL/s and exert the negative pressure on the output end under the standard condition of GB/T16447". Wherein the "standard conditions" mentioned above indicate a relative humidity of 60% and an atmospheric pressure of 10133 Pa. In actual measurement, humidity and atmospheric pressure are difficult to be strictly stabilized within the values of standard conditions, and usually fluctuate to some extent.
The existing cigarette resistance is measured by a comprehensive test bench for the physical properties of cigarettes and filter sticks. In order to weaken the influence of humidity and atmospheric pressure on the accuracy of cigarette suction resistance measurement, a suction resistance standard rod is firstly adopted to calibrate the comprehensive test bench, and then a comprehensive test bench is adopted to test cigarette samples. The comprehensive test bench for the physical properties of the cigarettes and the filter sticks is generally stored in a physical detection laboratory and a rolling and packing workshop, the humidity and the atmospheric pressure of the laboratory and the humidity and the atmospheric pressure of the rolling and packing workshop are different, and particularly the humidity is greatly different. Because the humidity and the atmospheric pressure during the test of the cigarette sample are different from those during the calibration of the suction resistance standard rod, the influence of the humidity and the atmospheric pressure on the accuracy of the cigarette suction resistance measurement cannot be effectively eliminated by adopting the suction resistance standard rod for calibration.
Therefore, how to provide a method capable of effectively eliminating the influence of humidity and atmospheric pressure on the accuracy of cigarette resistance measurement becomes a technical problem to be solved urgently in the field.
