| 摘要:本研究探讨了不同品系/树龄湿地松在硫酸盐法制浆过程中的性能。结果表明,不同品系湿地松在木材密度、纤维素含量、木质素含量、制浆得率及漂白性能等方面均存在较大的差异,其中树龄20年的A05品系的湿地松纤维素含量为42.15%,硫酸盐法制浆后的细浆得率为46.1%、卡伯值为22.5,漂白后可在最少的磨浆转数下达到较高的打浆度,表现出最优的制浆性能。 |
| Abstract:This study investigated the performance characteristics of different strains/tree-age of wetland pine during the kraft pulping process. The results indicated significant differences among the wetland pine in terms of wood density, cellulose content, lignin content, pulping yield, and bleaching performance. Among them, the cellulose content of the A05 wetland pine at 20 years of age was 42.15%, with a fine pulp yield of 46.1% after kraft pulping, and a Kappa number of 22.5. After bleaching, it could achieve a high degree of refining with the fewest number of refining revolutions, demonstrating the best pulping performance. |
