Background technology

Cigarette paper is one of important auxiliary material of cigarette product, and its burning performance directly influences the interior quality and the flue gas quality index of cigarette.Cigarette paper smolder speed physics assay method commonly used has following several: the assay method of performance " cigarette paper glow " that (1) GB/T12655-1998 " cigarette paper " appendix D provides; (2) existing YC/T197-2005 " assay method of cigarette paper smolder speed "; (3) the cloudy right rate determination method (CORESTA RECOMMENDED METHOD N ° of 53 DETERMINATION OF PAPERWRAPPER BURN SPEED) of the cigarette paper of CORESTA recommendation.

There is defective in varying degrees in above-mentioned three kinds of methods of measuring cigarette paper smolder speed, the first method cigarette paper is expansion and vertically glows, to be wrapped in shape on the pipe tobacco and people placement direction when the smoking cigarette different with cigarette paper for these, cigarette paper glowed combustion-supporting effect, launch to glow because of cigarette paper again, one does not have the influence of cigarette paper overlapping glue stick, its two since its be in the relatively large plane, therefore causing the line that glows irregular, also is the repeated relatively poor of the big and test result of the discreteness of test result; Second method is to launch Horizontal Smoldering, though the method cigarette paper and people placement direction when smoking cigarette is consistent, but they are different with the shape that cigarette paper is wrapped on the pipe tobacco, the one cigarette paper does not have the influence of cigarette paper overlapping glue stick when glowing, it two glows because of cigarette paper tiling and to be in the relatively large plane, and therefore also causing glowing, line is irregular, the discreteness of test result is big and test result repeated relatively poor; As if the third is the parallel method of glowing of reel, on the surface with to be wrapped in shape on the pipe tobacco and people placement direction when the smoking cigarette consistent with cigarette paper, but in fact has very big difference, and 1. cigarette paper is that horizontal multilayer (at least 6 layers) is wound into tubular; 2. the direction of glowing of cigarette paper is laterally to glow along it, rather than vertically glows.3. the influence of not having cigarette paper overlapping glue stick.

Through experiment, preceding two kinds of methods are glowed the cigarette paper line instability of glowing because cigarette paper is tiling, test result is discrete bigger, the third method can't be made judge to test result, but should exist than big-difference with the actual conditions of single laminate roll chimney owing to domesticly do not have this experimental apparatus.

Summary of the invention

Purpose of the present invention is just at the situation of above-mentioned prior art and a kind of assay method that is used for cigarette paper smolder speed that can truly reflect product quality characteristics and handling characteristics and easy operating that provides.

The objective of the invention is to realize by following scheme:

The assay method that is used for cigarette paper smolder speed of the present invention comprises following determination step:

The empty paper web specimen preparation of a, cigarette, and sample is placed on temperature is balance under the environment of (23 ± 1) ℃, relative humidity (50 ± 2) % more than 4 hours

B, set mark, along taking the A that mouthful makes a mark, take mouthful line direction from A point edge and measure certain distance L (mm) to filter end apart from the end 5mm place of glowing at empty paper web, and the B that marks;

C, fixed form are horizontally fixed on the empty paper web of carrying out mark on the support, and feasible taking on mouthful alignment;

D, test condition in the environment space that does not have convection current wind, are lighted the end that glows with the igniter of the flames of anger, light length less than 5mm, and the line that glows picks up counting when arriving A point, the timing end when arriving B point of glowing, and cigarette paper glows AB apart from used time T (s);

E, account form calculate the speed of glowing of cigarette paper by formula V=L/T, in the formula: L---and the cigarette paper distance of glowing, the mm of unit, T---cigarette paper glow the used time of distance L, the s of unit.

In the present invention, the preparation of the empty paper web sample of described cigarette can be in the following manner: the pipe tobacco in the finished cigarettes is taken out the back and form, utilize cigarette paper to roll by machine or manually roll into the sky paper web to form.

The fixed form of empty paper web is that the filter tip level by its end is inserted on the spicule on the support.

Assay method of the present invention is compared the problem that emphasis has solved the following aspects with existing three kinds of method of testings: the 1. repeatability of test result; 2. the stability of test result; 3. test result more truly reflects product quality characteristics; 4. the handling characteristics of the true more representative products of test result; 5. the operability of method.Test findings shows: because cigarette paper is the unsettled horizontal positioned of individual layer tubular and glows, sample is in the less relatively space, make that its line that glows is neat, the test result good reproducibility, and discrete less also be that the coefficient of variation is little, the mass property and the handling characteristics that can reflect product truly, moreover the method is easy operating also.
