Abstract

The invention relates to a method for determining the fiber distribution uniformity of paper-making-process reconstituted tobacco pulp by virtue of Euclidean distance. The method comprises the steps of dividing one pulping batch into T (more than or equal to 3) time periods at equal intervals in a papermaking process of the reconstituted tobacco pulp, constructing T+2 time points according to a time sequence, simultaneously detecting a microstructure of a reconstituted tobacco pulp sample obtained an approach flow concentration determination position for six times at each time point i, carrying out dimensionless processing on detection data by taking 6 indexes including average length, mean width, twisting degree, fiber fine content, crimping rate and roughness of the fiber as standard points, and calculating Euclidean distances d<ijk> of six detection samples at a certain time point i; and then calculating the Euclidean distances d<iljk> of one pulping batch of detection samples, and determining the certain time point i of one pulping batch and the uniformity of the microstructure of the fiber of one batch of reconstituted tobacco pulp based on the Euclidean distances. The method provides a method and basis for realizing automatic control on the quality of the paper-making-process reconstituted tobacco pulp.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaf technology, and in particular relates to a method for judging the fiber distribution uniformity of reconstituted tobacco leaf pulp by using the Euclidean distance. Background technique [0002] The results of production practice and literature research show that the physical characteristics of the papermaking reconstituted tobacco leaf base are the main factors affecting the quality of the papermaking reconstituted tobacco leaf product. There have been a lot of literature reports on it. Wen Yangbing and others studied the research on improving the bulkiness of tobacco substrate in papermaking method; Song Chengjian et al. studied the comparison of beating effect between high-consistency and low-consistency tobacco pulp; Xiao Xuanhu et al. studied the stability of tobacco pulp high-consistency pulping process and fiber classification distribution impact research; Feng Hongtao et...
