て、無機処理を終わる。FIG. 2 is a process explanatory diagram showing the inorganic treatment of the wood piece 2 and subsequent steps in this invention. As shown in the figure, a piece of wood 2 of a predetermined size is placed in a basket 8, immersed in a water tank 3, and subjected to water saturation treatment.Such water saturation treatment may be performed under reduced pressure, or the water may be boiled. After that, immersion in an aqueous solution 4 of inorganic cations (1 liquid immersion),
Next, it is immersed in an aqueous solution 5 of inorganic anions (two-liquid immersion). The order of dipping the first liquid and the second liquid is not particularly limited, and the order may be changed. After the two-liquid immersion, the dipping is performed again. The soluble content is removed from the wood chips 2 in another water tank 6 and the wood chips 2 are dried to complete the inorganic treatment.

応させるために、含浸率を向上させ易い。According to the structure of the present invention, the wood material is impregnated with an aqueous solution of inorganic cations and an aqueous solution of inorganic anions in order to form an insoluble inorganic salt inside the wood material. Since it produces insoluble salts inside the wood, it hardly changes the appearance, and since it is a nonflammable inorganic salt, it improves the flame retardancy of organic gas. Furthermore, since it is impregnated in the state of soluble ions and reacted after impregnation, it is easy to improve the impregnation rate.

Impregnation treatment was carried out for 24 hours.
つぎに、無機処理した木材単板を常温水に24時間を浸
漬処理して、可溶分を除去した。Next, the inorganically treated wood veneer was immersed in room temperature water for 24 hours to remove soluble components.
つぎに、木材単板を含水率が10%以下になるまで乾燥
した。Next, the wood veneer was dried until the moisture content became 10% or less.
その結果、得られた処理木材単板は、JIL5502(
