摘　　要：该实验探讨了在杨木碱性过氧化氢机械浆（APMP）漂白中加入尿素对纸浆ISO白度和打浆性能的影响以及在尿素存在的情况下过氧化氢（H2O2）漂白的最佳工艺。结果表明，加入尿素能提高纸浆白度，并且对纸浆的物理强度没有明显的影响，同时能降低生产成本和减轻后续处理的负担。The influence of carbamide addition on pulp ISO brightness and beatability in aspen alkaline peroxide mechanical pulp（APMP） bleaching and optimized process of peroxide bleaching with existence of carbamide were introduced in this paper. The result shows that adding carbamide can improve pulp brightness while it has no evident influence on paper physical properties, and it can reduce production cost and release the pressure of the post processing meanwhile.
