摘要：本文对马占相思CTMP浆料性能、H2O2漂白适宜碱比、DTPA添加方式及两段H2O2漂白工艺进行了研究。结果表明,适宜碱比与H2O2用量之间有较强的相关关系;DTPA漂前预处理使用效果好,可以减少H2O2的分解,提高终漂白度;两段漂白工艺可以提高终漂白度上限值,达到72%ISO。
The paper investigates the peroxide bleaching properties of chemithemomechanical pulp from Acaciamangium,including optimum alkalinity ratio for H2O2 bleaching,the adding method of DTPA and the two-stage peroxidebleaching technology.The results show that there exists a strong dependence relation between optimum alkalinity ratio andH2O2 charge,the sequestering efficiency is higher while the chelating agent of DTPA is added prior to bleaching stage thanin bleaching stage because the decomposition of H2O2 is much smaller by doing so and the two-stage bleaching technologycan obtain better upper limit value of the final bleaching brightness with 72% ISO reached.
