A novel approach to avoiding white pitch deposition

White pitch, generated from synthetic binders, is introduced to paper machi ne systems through the use of recycled-coated paper or coated broke. To min imize white pitch agglomeration and deposition in the paper machine circuit , the use of a cationic fixing agent is common. A unique polymer has been d eveloped to improve white pitch fixation. A laser-optical particle counter was used to evaluate the effectiveness of this polymer, compared to polyami ne.
