摘　　要：结合软木材料的特点,分析研究漂白剂的性能,选取过氧化氢(H_2O_2)作为软木材料的漂白剂;采用SC-80C全自动色差计对漂白试样进行白度的定量测量,综合考虑定性观察和定量检测的结果,确定软木材料的最佳漂白工艺条件为:过氧化氢浓度为9%,漂白时间为60 min,漂白温度为70℃,漂白液的pH值为10。以白度为评价指标,各因素对漂白效果影响的程度从大到小依次为:温度,时间,过氧化氢浓度,pH值。各因素对白度的影响都很显著。According to the characteristic of the cork material, analyzing and researching the property of various bleaching agents and choosing H2O2 as bleaching agents for cork material bleaching, and using full-automatic chromatic aberration meter of SC-80C to quantitively gauge the chromatic aberration and whiteness of bleached sample. On the basis of considering the result of qualitative observation and quantitative determination, the best bleaching process conditions for cork material are obtained as follows： H2O2 concentration of 9% , heating time of 60 min, temperature of 70℃ and pH value of 10. Influence of all above mentioned factors is of markedness, and the arrangement in order of the factors affecting the whiteness of bleached sample is as follows： temperature, time, concentration of H2O2 and pH （from big to small）.
