を行い木質材料系レンガ７とした。An embodiment of the present invention will be described based on FIGS. 1 and 2. A piece of wood 1 (length 100MX width 100au*X thickness 45threshold) made of Hinoki wood with the end side on the thickness side is 8
After heat treatment in hot water 2 at 0°C for 24 hours, impregnation treatment at 80°C for 24 hours in an aqueous inorganic cation solution 4 in which 42 kg of barium chloride dihydrate and 11 kg of boric acid were dissolved in 100 kg of water, followed by ammonium phosphate treatment. The wood chips were impregnated with an inorganic anion aqueous solution 5 prepared by dissolving 106 kg of boric acid and 37 kg of boric acid in 100 kg of water at 80"C for 24 hours to generate inorganic salts inside the wood chips.Furthermore, the wood chips 1 were soaked with room temperature water 6 for 24 hours.
After being immersed for a period of time to dissolve unreacted inorganic ions, the wood piece 1 is dried until the moisture content is 10% or less, cut out (length 70 m x width 70 m x thickness 40 m), and chamfered to create a wood material. It was made into a series brick 7.
