Abstract
The invention provides a method for testing the smoldering rate of re-manufactured tobacco leaves by means of a papermaking process and belongs to the technical field of re-manufactured tobacco leaves. The method for testing the smoldering rate of the re-manufactured tobacco leaves by means of the papermaking process is characterized in that the time (t) required for burning a certain length (L) of an ignited re-manufactured tobacco leaf product with a certain width under non-naked light condition is recorded under certain environmental conditions, and the ratio of the time to the length is the smoldering rate of the re-manufactured tobacco leaf product. The method for testing the smoldering rate of the re-manufactured tobacco leaves by means of the papermaking process has the advantages of being simple, convenient, easy to operate and accurate, and tested index can represent the burning performance of the re-manufactured tobacco leaves by means of the papermaking process.
Description
Technical field
The invention provides a kind of assay method of papermaking-method reconstituted tobaccos Smoldering rate, belong to the reconstituted tobacco technical field.
Background technology
Reconstituted tobacco is take tobacco secondary product and discarded object (offal, fragment and broken end etc.) as raw material, and the resource regeneration product that grows tobacco that processes in conjunction with certain manufacturing process.Reconstituted tobacco is a kind of important cigarette material, adds an amount of reconstituted tobacco in pipe tobacco, can play the effect that improves cigarette physical property, lowering harm and decreasing coking, also can save smoke material simultaneously, reduce the cigarette cost.
The reconstituted tobacco burning performance is one of important indicator of weighing the reconstituted tobacco end product quality, reconstituted tobacco finished product Smoldering rate refers to the distance that the reconstituted tobacco finished product burns in the unit interval under non-naked light condition, with formulae express be: Smoldering rate=distance/time, unit are the millimeter 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 third part: paper process ", with reconstituted tobacco finished product sheet accurately cut 200mm * 15mm(long * wide) 10 on sample, record the every sample 150mm required time that vertically glows, calculate Smoldering rate.And at present the papermaking-method reconstituted tobaccos finished product that dispatches from the factory is small pieces, and current methods can't satisfy the real work demand.
This method can directly be measured reconstituted tobacco finished product sample cuttings Smoldering rate, is particularly suitable for the Smoldering rate that cigarette enterprise is measured the reconstituted tobacco finished product quickly and easily.
By literature search, have no the open report identical with the present invention.
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 on sample, the long and wide franchise of intercepting sample is ± 0.1mm.Rejecting has the sample of open defect, such as: folding, lumps, hole and the sample such as moist.Carry out two mark lines on the sample, the mark wire spacing is 25mm, and mark line is 5mm apart from the intercepting Edge Distance.
2) mensuration of Smoldering rate
Light sample one end with portfire, when sample glows to article one mark line, the beginning timing; In the sample smoldering process, the end that glows should not surpass ± 15 ° with level (or vertical) angular separation, otherwise these data should be rejected; When sample glowed to the second mark line, timing finished.
3) Smoldering rate of calculating sample is seen formula (1).
In the formula: V--reconstituted tobacco sample Smoldering rate, the mm/s of unit; T--reconstituted tobacco sample glows the time, the s of unit; The L--distance of glowing, 25mm;
With the mean value effectively measured for the 10 times Smoldering rate as sample, the result is accurate to 0.01mm/s.
That the inventive method has is easy, feasible, advantage accurately, is applicable to the Smoldering rate of papermaking-method reconstituted tobaccos working sample.
