Embodiment

[0077] The sample filter rod analysis model is established,

[0078] 1. Collect the filter rod sample spectrum

[0079] (1) For the sampling cup with a diameter of 5 cm, tie the filter rod samples (50 conventional filter rod samples and 85 fine filter rod samples) with two rubber bands, insert the sampling cup, and place it on the rotating table;

[0080] (2) Set the spectrum acquisition parameters of the near-infrared instrument as: wave number range 4000-10000 cm-1, scanning times 64 times, resolution 8 cm-1.

[0081] 2. Determine the content of triacetin in the filter rod sample

[0082] The industry standard YC / T 331-2010 "Determination of Triacetin in Cellulose Acetate Filter by Gas Chromatography" was used to detect the accurate content of triacetin in the filter.

[0083] 3. Establish a quantitative analysis model for filter rod triacetin

[0084] (1) The distribution of triacetin content of filter rods in the modeled samples is 0-14% (including but not limited to ordinary filter r...

Abstract

The invention provides a method for determining the content of glyceryl triacetate. The application amount of glyceryl triacetate in a filter stick is accurately detected and controlled, so that the hardness of the filter stick is stabilized, the smoking quality of cigarettes is improved, the release amount of phenol in smoke is indirectly monitored, and the release amount of harmful components incigarette products is reduced.

Description

Technical field [0001] The invention relates to a method for rapidly measuring the content of triacetin in cigarette filter sticks. Background technique [0002] Glyceryl triacetate is often used as a plasticizer and curing agent in the processing and production of cellulose acetate filter rods, and its content can affect the hardness, resistance and filtering effect of the filter rod. In addition, studies in recent years have found that the addition of glycerol triacetate in filter rods can reduce the release of phenol in smoke. Therefore, detecting and controlling the amount of glycerol triacetate in the filter rod can not only stabilize the hardness of the filter rod and improve the smoking quality of cigarettes, but also indirectly monitor the release of phenol in the smoke, and provide accurate information for reducing the release of harmful components in cigarette products. Scientific data. [0003] At present, the filter rod production workshop mostly uses the gravimetric ...
