An orthogonal experiment was conducted to investigate the bleaching technology for water-extracted veneer of Eucalyptus urophylla × grandis. Taking the whiteness and color difference of the bleached veneer as indexes, the factors that could affect the bleaching results were evaluated, including bleaching temperature, time, and the concentration of Na2SiO3 and H2O2. Results found that the pH value of the bleaching solution only influenced the bleaching rate, and had almost no effect on the bleaching quality. The optimum parameters were determin...
