Method for determining cigarette paper smolder speed

Abstract

The invention relates to a measuring method of smoldering speed of cigarette paper, which comprises a, preparing a cigarette hollow paper drum sample, b, setting relative marks, c, setting fixing method, d, setting test conditions, e, calculating out the cigarette paper smoldering speed via formula. Compared with prior three test methods, the invention has the advantages that 1, the test result has good repeatability, 2, the test result has good stability, 3, the test result can actually represent product quality, 4, the test result can represent the application character of product, 5, and the method has good operability. The test result indicates that since the cigarette paper has single-layer drum structure, is suspended and horizontally arranged and smoldered, the sample is in one small space, to make smoldering line regular, obtain the test result with good repeatability and reduce dispersion as small variation factor, thereby truly representing the quality and application character of product.

Description

technical field [0001] The invention relates to the measurement of the burning performance of cigarette paper, in particular to a method for measuring the smoldering rate of the cigarette paper, which can measure the quantitative index of the smoldering performance of the cigarette paper. Background technique [0002] Cigarette paper is one of the important auxiliary materials of cigarette products, and its combustion performance directly affects the intrinsic quality of cigarettes and smoke quality indicators. Commonly used methods for the physical determination of the smoldering rate of cigarette paper are as follows: (1) "Measurement method for the smoldering performance of cigarette paper" provided in Appendix D of GB / T12655-1998 "Cigarette Paper"; (2) the current YC / T197- 2005 "Measurement Method for Smoldering Rate of Cigarette Paper"; (3) CORESTA Recommended Method for Determination of Smoldering Rate of Cigarette Paper (CORESTA RECOMMENDED METHOD N 0 53 DETERMINATI...

AI Technical Summary

Problems solved by technology

[0003] The above three methods for measuring the smoldering rate of cigarette paper have defects in varying degrees. The first method is that the cigarette paper is unfolded and smoldered vertically, which is different from that of cigarette paper. The shape wrapped on the shredded tobacco and the direction in which people place cigarettes when smoking are different, which has a combustion-supporting effect on the smoldering of the cigarette paper, and because the smoldering of the cigarette paper unfolds, firstly, there is no influence of the adhesive on the mouth of the cigarette paper, and secondly, due to its It is in a relatively large plane, so the smoldering line is not neat, that is, the dispersion of the test results is large and the repeatability of the test results is poor; the second method is to unfold the horizontal smoldering, although this method The paper is placed in the same direction as when people smoke a cigarette, but it is different from the shape of the cigarette paper wrapped on the shredded tobacco. One is that the cigarette paper does not have the influence of the adhesive on the cigarette paper when it is smoldering, an
