摘要
简要叙述漂白活化剂TAED的性质、活化机理及其在脱墨废纸浆漂白中的应用。TAED的加入,对H2O2脱墨浆漂白具有明显的改善作用,影响其漂白效果的因素有:TAED与H2O2的摩尔比、温度、时间、NaOH的用量及H2O2的用量。同时,TAED活化可降低漂白温度,缩短漂白时间,这就意味着可以减少能耗,降低生产成本。
This article briefly described the nature and the activation mechanism of bleaching activator TAED,and the application of bleaching DIP. The addition of TAED has significant impact on the hydrogen peroxide bleaching, the effectiveness factors of the bleaching was the molar ratio of TAED to hydrogen peroxide, temperature, time, amount of sodium hydroxide and hydrogen peroxide dosage. At the same time, the bleaching of waste paper deinking pulp activated by TAED can drop the temperature and shorten the bleaching time, which means that can reduce energy consumption, lower production costs.
