研究H2O2漂白过程中4种活化剂对纸浆白度、黏度和卡伯值的影响。结果发现TAED促进白度增加最明显,而黏度、卡伯值降低不大;1-10菲啰啉在较少用量(0.2%)时促进效果最好,但纸浆黏度和卡伯值下降太多,所以选择应该慎重;乙酰胺作为活化剂在足够用量和时间时能达到TAED的效果,因此是一种实用的活化剂。
The effects of four activators on whiteness, viscosity and kappa number of pulp during H2O2 bleaching were studied. The results showed that TAED promoted the whiteness increase the most obviously, while the viscosity and Kappa number decreased little. The 1-10 phenanthroline had the best promoting effect when the dosage was lower (0.2%), but the pulp viscosity and kappa number dropped too much , So the choice should be cautious; acetamide as a activator in a sufficient amount and time to achieve the effect of TAED, it is a practical activator.
