摘要:本研究在室温条件下,探究了活性电解水对硫酸盐针叶木浆的漂白效果,同时分析了液比、漂白时间等工艺参数对纸浆CIE白度、卡伯值、纤维素聚合度、力学性能等的影响。结果表明,在室温静置条件下漂白12 h后,硫酸盐针叶木浆的白度可由22.7%提升至71.3%,卡伯值2.95,纤维素聚合度918,且纸浆力学性能保持良好;活性电解水无色无臭、温和无刺激,使用前后pH均保持中性。活性电解水含有活性氧物种如超氧自由基(·O2-![]() ),能有效与纸浆中的木质素反应,降低纸浆中木质素含量,破坏发色基团,提高纸浆白度。 |
Abstract:In this study, the bleaching performance of kraft softwood pulp with active electrolyzed water at room temperature was investigated, and the effects of process parameters such as pulp-to-liquid ratio and bleaching time on pulp properties including CIE whiteness, Kappa value, polymerization degree of cellulose, and mechanical strength of pulp were analyzed. The results showed that the whiteness of kraft softwood pulp could be increased from 22.7% to 71.3%, with a Kappa value of 2.95, polymerization degree of cellulose of 918, and good mechanical properties under static conditions at room temperature for 12 h. Activated electrolyzed water was colorless, odorless, mild, and non-irritating, with a neutral pH maintained both before and after use. Comprehensive test results indicated that active electrolyzed water contained active oxygen species such as superoxide radicals(·O2-![]() ), which could react with the lignin in the pulp effectively, reduced the lignin content of pulp, disrupt the chromophore structure, and improved the whiteness of pulp. |
