Abstract (en)
[origin: WO9426973A1] The invention concerns a method of monitoring the deposition of stickies from paper-pulp suspensions in the manufacture of paper. In this method, the deposition of secondary stickies is monitored by adding to the paper-pulp suspension, immediately before the first and/or other flotation stages, calculated with respect to the dry pulp, 0.2 to 3.0 % by wt. of waterglass and/or 0.05 to 1.0 % by wt. of a fatty acid with essentially 12 to 22 C-atoms or a salt thereof with a mono- to trivalent cation.
