Abstract

PURPOSE:To improve the dimensional stability and processability under the condition that the flame retardancy and corrosion resistance of the ply wood concerned are held as they are by a method wherein inorganic salt is produced at high percentage of impregnation in the interior of each cope veneer consisting of ply wood while inorganic salt is produced at a low percentage of impregnation in each face layer veneer. CONSTITUTION:A wood veneer 1 is immersed in hot water 3 for water saturation treatment and, after that, in water solution 4 of inorganic cation such as Al<2+>, Mg<2+>, Zn<2+>, Ca<2+> or Ba<2+> and then in water solution 5 of inorganic anion such as HPO, CO, SO or BO. In said impregnation treatment, the higher the concentrations of the water solutions and the treatment temperature become and the larger the treatment time becomes, the higher the percentage of impregnation becomes. Or by repeating the alternate immersion treatments in the water solution 4 of inorganic cation and in the water solution 5 of inorganic anion several times, the percentage of impregnation can be enhanced. The percentage of impregnation can be controlled by changing the combination of said conditions. Finally, for finishing said inorganic treatment, the wood veneer is immersed in water and, after that, dried.
