摘　　要：以双氧水为漂白主剂,利用不同的漂白配方对变色柞木刨切薄木进行漂白试验。在适宜的漂白温度下,以双氧水浓度、硅酸钠浓度、漂白时间为考查因素进行正交试验,并对漂白后柞木刨切薄木的色差和白度进行检测和分析,结果表明,优化漂白工艺为双氧水浓度3%,硅酸钠浓度0.7%,常温下漂白30min,浴比为10:1,漂白溶液pH值为10。Hydrogen peroxide was chosen as the main bleaching agent for the bleaching test via different formulations. At the optimum bleaching temperature, the orthogonal test focused on the following factors： concentrations of H2O2 and Na2SiO3, and bleaching time; meanwhile, the chromatism and whiteness of the bleached Oak sliced veneer were measured and analyzed. The result indicated that the optimum process was with concentration of H2O2 at 3%, Na2SiO3 at 0.7%, bleaching for 30 min at room temperature, bath ratio 10ft, and pH at 10.
