FIELD: paper industry.
SUBSTANCE: invention is related to paper industry, particularly to techniques for monitoring and control of contaminants (microsticks) and macroscopic contaminants (macrosticks), and a method and device for measuring the efficiency of the additive introduced into aqueous suspension of cellulose mass. Claimed process aims at fast determination of size and content of macrosticks, particles with the diameter over 100 microns, in flows of secondary processed cellulose mass. Said technology is based on the fluorescence analysis of image in order to identify and count viscous elements of sticks, as well as to measure their size.
EFFECT: invention ensures higher efficiency of controlling quality of paper mass.
