Latest Patents
Kamijo's latest patents include a method for deinking recovered paper and a process for impregnating, refining, and bleaching wood chips with low bleachability. The first patent focuses on producing deinked pulp from recovered paper containing stickies while minimizing the reduction in the size of stickies and lowering the COD of effluents. This innovative process involves adding an anhydride of crystalline layered silicate during the ink detachment stage, allowing for effective deinking at a pH of 7.0-9.9. The second patent addresses the challenge of preparing mechanical pulps with high brightness from wood chips that are difficult to bleach. By using a chemical liquor at a pH range of 7-12, the process enhances the effectiveness of bleaching agents, resulting in bleached mechanical pulp with a Hunter brightness of 45-65% after secondary refining.
