Detailed Description of the Invention This invention provides a treatment method for removing harmful components in wood.
4 L. By immersing wood in a soaking solution containing one selected from the group consisting of magnesium oxide and magnesium hydroxide, harmful components can be efficiently removed without causing deterioration of the wood. This allows the work to be carried out completely and easily.

However, methods using organic solvents have the disadvantage that the color or pattern of the wood changes significantly or is otherwise ineffective, and there is also the risk of ignition and problems with work hygiene. Further, the method using a mixed aqueous solution of an alkali and a surfactant also has the disadvantage that the color and pattern of the wood change due to the alkali, and furthermore, the quality of the material deteriorates significantly.

The method for treating wood of the present invention includes an immersion liquid in which one or more selected from magnesium oxide and magnesium hydroxide is dispersed or suspended in water, preferably one selected from the group consisting of magnesium oxide and magnesium hydroxide. 1
The wood is immersed in an immersion solution in which seeds or more are dispersed and suspended in a formalin water bath.

Magnesium oxide (M g O) has a 1-force on its -;
It dissolves in water, and most of the others exist in a dispersed or suspended state in water to extract quinones etc. from wood.
If it is less than 5 parts by weight, this effect cannot be obtained, and if it exceeds 5 parts by weight, no increase in the removal effect can be expected, which is economically disadvantageous.

Formalin (HCI-IO2y% aqueous solution) assists the harmful component removal action of magnesium oxide or magnesium hydroxide, and is not necessarily required. If formalin exceeds 100 levels, the amount of unreacted formalin would increase, resulting in higher costs and increased safety and health risks, which would be inconvenient.

It is desirable to add a heating jacket to the device to heat it to the above temperature range. The soaking time ranges from several hours to several days, and is determined as appropriate depending on the shape of the wood, soaking humidity, degree of treatment, etc. Furthermore, in order to promote the removal action during immersion, a simple stirring device such as a propeller type stirring device a is used.
The immersion liquid may be stirred by providing a Note that when the immersion liquid is humidified, water vapor containing formaldehyde is generated from the cypress, so it is preferable to install a cooling pipe on the top of the cypress to reflux the generated steam. It is desirable to have a closed structure.

After the treatment, the veneer was washed with water and dried in an IRL at room temperature for 3 days or more, and the veneer was ground with a grinder. This wood flour was subjected to Soxhlet extraction with 1]-hexane and benzene, and this extract was then replaced with methanol, and then analyzed by liquid chromatography to measure quinones in the extract. For comparison, a veneer without immersion treatment was similarly treated and quinones were measured. The content of non-galvanic acid in the case of immersed and ld-treated water is higher than that of the non-dipped case. It was found that the quinones in Baraferro were effectively removed.
