| titleOfInvention | Method for preparing paper and paper board |
| abstract | To provide a method for producing paper and paperboard, which corresponds to the improvement in the availability of waste paper, the improvement in the blending rate of flock pulp, the closing of thesystem, and the like, controls pitches, reduces defects, does not disrupt the formation, improves freeness and yield, and can improve productivity such as the reduction in paper breakage and production speed-up. This method for producing the paper and the paperboard comprises adding a water-soluble cationic polymer to a paper material, adding a water-soluble amphoteric polymer to the paper material through at least one shearing step, further adding the fine particles of an anionic organic polymer to the paper material through at least one shearing step, dehydrating the mixture in a sheet shape, and then drying the sheet. |
