Abstract: In order to eliminate colour difference of bamboo hydrosulfite were all prepared for the following tests.
sheets, the energy saving technique of bamboo bleaching rapidly B Methods
based on water resource protection was studied. The results The four bleaching solution formulas were prepared: formula
showed that the appropriate addition agent may improve A, alkaline; formula B, strong alkaline; formula C, acidic;
function of H O bleaching bamboo. the oxidation of H O was
2 2 2 2 formula D, neutral. The every 30 bamboo pieces were treated
the best at 80°С. If the temperature was too low or too high, the
bleaching effect was bad. And the bleaching solution formula in the four bleaching solutions, respectively. When arrived 6h,
had the influences on bleaching effect. Alkaline bleaching 12h and 18h at 80°С, the 10 bamboo pieces were taken out
solution formula was better. from the four bleaching solutions based on table 1. And the
bamboo pieces were dried in 105°С for 3h. Then the
