摘　　要：探讨了影响硫酸盐竹浆高温高压H_2O_2漂白效率的几个重要因素,确定了适宜的工艺条件。实验结果表明,通过控制H_2O_2用量、H_2O_2/NaOH用量比、压力、温度、时间等工艺条件,可以明显提高硫酸盐竹浆高温高压H_2O_2漂白的效率,而且不会造成过大的黏度损失。Several improvement factors affecting high temperature and high pressure hydrogen peroxide bleaching efficiency of bamboo kraft pulp are discussed and the optimum technology is determined. The experimental results show that high temperature and high pressure hydrogen peroxide bleaching efficiency of bamboo kraft pulp can be improved significantly by controlling the process conditions （H2O2 dosage; H2O2/NaOH dosage ratio; pressure; temperature; time etc）, while the viscosity of the pulp does not suffer a great loss.
