发明名称 A METHOD FOR REDUCING THE LEVEL OF INTERFERENCE CHEMICALS INTHE WATER CIRCULATION OF WOOD-BASED FIBRE SUSPENSION PROCESSES
摘要 The invention relates to a method for reducing the amount of interference substances in the water circulations of processes involving wood-based fibre suspensions by binding the disturbance substances to the fibres by means of cationic starch. The amount of the said starch added to the fibre suspension is approximately 0.0 4- 0.5 % of the fibre dry weight.
