Abstract
The invention provides a kind of assay method of papermaking-method reconstituted tobaccos Smoldering rate, belong to reconstituted tobacco technical field, it is characterized in that: under certain environmental conditions, the reconstituted tobacco finished product of record one fixed width light after time (T) of burning under non-naked light condition required for certain length (L), both ratios are the Smoldering rate of this reconstituted tobacco product.The inventive method has easy, feasible, advantage accurately, and the index measured can characterize papermaking-method reconstituted tobaccos burning performance.
Description
Technical field
The invention provides a kind of assay method of papermaking-method reconstituted tobaccos Smoldering rate, belong to reconstituted tobacco technical field.
Background technology
Reconstituted tobacco is with tobacco secondary product and discarded object (offal, fragment and broken end etc.) for raw material, and growing tobacco resource regeneration product of processing in conjunction with certain manufacturing process.Reconstituted tobacco is a kind of important cigarette material, adds appropriate reconstituted tobacco in pipe tobacco, can play the effect improving cigarette physical property, lowering harm and decreasing coking, also can save smoke material simultaneously, reduce cigarette cost.
Reconstituted tobacco burning performance is one of important indicator weighing reconstituted tobacco end product quality, reconstituted tobacco finished product Smoldering rate refers to the distance that in the unit interval, reconstituted tobacco finished product burns under non-naked light condition, by formulae express be: Smoldering rate=distance/time, unit is that millimeter is per second.
At present, the measurement of reconstituted tobacco finished product Smoldering rate is carried out with reference to industry standard " YC/T 16.3-2003 reconstituted tobacco Part III: paper process ", reconstituted tobacco finished product sheet is accurately cut 200mm × 15mm(long × wide) 10, sample, record every bar sample vertically to glow 150mm required time, calculate Smoldering rate.And at present the papermaking-method reconstituted tobaccos finished product that dispatches from the factory is small pieces, current methods cannot meet real work demand.
This method directly can measure reconstituted tobacco finished product sample cuttings Smoldering rate, is particularly suitable for the Smoldering rate that cigarette enterprise measures reconstituted tobacco finished product quickly and easily.
By literature search, the open report identical with the present invention is had no.
Summary of the invention
The object of the present invention is to provide a kind of easy, feasible, papermaking-method reconstituted tobaccos Smoldering rate assay method accurately.
Concrete steps of the present invention are as follows:
1) sample preparation
From sample, intercept 35mm × 15mm(long × wide) 20, sample, intercepting the long and wide franchise of sample is ± 0.1mm.Reject and have the sample of open defect, as: the samples such as folding, lumps, hole and humidity.Sample is carried out two mark lines, mark line spacing is 25mm, and mark line is 5mm apart from intercepting Edge Distance.
2) mensuration of Smoldering rate
Light sample one end by portfire, when sample glows to Article 1 mark line, start timing; In sample smoldering process, the end that glows should not exceed with level (or vertical) angular separation ± and 15 °, otherwise these data should to be rejected; When sample glows to Article 2 mark line, timing terminates.
3) calculate the Smoldering rate of sample, see formula (1).
In formula: V--reconstituted tobacco sample Smoldering rate, unit mm/s; T--reconstituted tobacco sample glows the time, unit s; L--glows distance, 25mm;
Using the mean value of 10 effective mensuration as the Smoldering rate of sample, result is accurate to 0.01mm/s.
The inventive method has easy, feasible, advantage accurately, is applicable to the Smoldering rate of papermaking-method reconstituted tobaccos working sample.
Embodiment
The present invention is further described by following specific embodiment, but does not limit the present invention:
Embodiment 1
