METHOD OF PREPARATION OF PAPER-MAKING STOCK FOR PAPER PRODUCTION Russian patent published in 1997 - IPC

FIELD: wood-pulp and paper industry. SUBSTANCE: the essence of the offered method consists in magnetic treatment of polymer solution before its introduction into composition basin. In so doing, polymer macromolecules are turned into linear chain along the lines of magnetic induction to increase its system length. Due to it, number of points of polymer contact with cellulose fibers increases, and, as a result, efficiency of polymer utilization rises, and its consumption drops and mechanical parameters of produced paper improve. After composition basin, paper-making stock is supplied for paper sheet formation. EFFECT: higher efficiency. 2 dwg
