GB/T 31786-2015Tobacco and tobacco products -- Non-destructive determination of strips density variation ratio in case -- Ionizing radiation method (English PDF)

0.1 Background

Box sheet smoke density deviation ratio (DVR) is one of the important factors affecting the sheet tobacco Aging effect and silk quality. If the density deviation rate over Large sheet tobacco Aging process in oil-prone, caking even carbonized, and in the difficult process of silk loose; density deviation rate can also lead to excessive cigarette Taste and quality degradation, it is necessary to detect front silk sheet density deviation rate inside the smoke.

Previously used "9.00 Law" (see reference [1]) detected smoke density deviation inside the chip rate, but the method for destroying smoke box test, the detection time Long and only suitable for off-line testing. In contrast, non-destructive testing method not only does not destroy the measured smoke box, quick and easy, but also applies to online testing and off-line testing.

Ionizing radiation method has been widely used in other fields (IEC 60692:1999) (see Ref. [2,3]), the International Electrotechnical Commission (IEC ) has developed X- ray detection equipment safety standards (IEC 60405:2003) (see reference [4]). Penetrating X- ray films after the smoke box Intensity of the test substance (ie, inside the sheet tobacco) is directly related to the density of ionizing radiation law applies to smoke inside the sheet density line detection and error rate Off-line testing, non-destructive, rapid, secure and low cost. X- ray detection equipment used in this standard in line with relevant international standards, meet Safety requirements. This method is suitable for the detection of smoke density inside the sheet.

Smoke detection chamber slice density deviation rate of many other detection systems have the same precision can also be used.
