空气对漂白化学浆铜乙二胺溶液黏度的影响

Effect of Air on Cupriethy Lenediamine Viscosity of Bleached Chemical Pulp

研究了在测定漂白化学浆黏度过程中,溶解瓶中的空气对纸浆铜乙二胺溶液黏度的影响。结果表明,在纸浆溶解于铜乙二胺溶液过程中,溶解瓶中的空气会使纤维素发生降解,而且随空气量的增加和溶解摇动时间的延长, 纸浆的黏度下降。但当溶解瓶中只含有少量空气时,对纤维素降解影响甚微。

The paper has studied the effect of air on viscosity of pulp dissolved in cupriethy lenediamine solution. Results show that cellulose is degraded as a result of increasing the air in dissolving bottle and prolonging the time of pulp dissolving. But when there is a little air in the dissolving bottle during the pulp dissolving, the viscosity of pulp is dropped slightly.
