摘　　要：探讨硫酸盐竹浆高温高压H2O2漂白中影响木素脱除率和黏度降低率的几个重要因素,并确定适宜的工艺条件。实验结果表明,通过控制工艺条件(压力、温度、时间、H2O2/NaOH用量比等),可以明显提高硫酸盐竹浆高温高压H2O2漂白中的木素脱除率,而且黏度损失较低。The important factors of the impact of high temperature and high pressure hydrogen peroxide bleaching lignin removal efficiency of bamboo kraft pulp are discussed to determine the optimum technology. The experimental results show that by controlling the process conditions（pressure,temperature,time, H2O2/NaOH dosage ratio etc）, can significantly enhance high temperature and high pressure hydrogen peroxide bleaching lignin removal efficiency of bamboo kraft pulp, and will not cause too great loss of viscosity.
