    Abstract: The present disclosure relates to the technical field of wood preparation, and in particular, to a method and device for preparing a magnetic bamboo wood. A technical problem to be solved in the present disclosure is that: Lignin in a wood will affect the soaking efficiency of the wood during soaking of the wood. In the present disclosure, sodium hydroxide and sodium sulfite in a ratio of 2:1 are put into the soaking bucket in sequence through the high-precision powder weighing equipment and are fully dissolved in distilled water to obtain a solution, so that the solution reacts with the lignin in the bamboo wood to elute the lignin, which increases the porosity of the bamboo wood, improves the soaking efficiency, and improves the magnetism of the bamboo wood.

    Abstract: The present invention relates to a method for continuous acetylation of wood elements. The acetylation is conducted with an acetylation medium at a pressure of at least 1.5 barg in a substantially oxygen free environment. Alternatively, the method according to the invention comprises the steps of: (a) feeding wood elements in a substantially oxygen free environment to a continuous acetylation reactor, and (b) treating the wood elements with an acetylation medium in the continuous acetylation reactor under wood acetylation reaction conditions, at a pressure of at least 1.5 barg.The process according to the present invention allows to acetylate wood elements to a high acetyl content in a very efficient way, without compromising on the quality of the material. The acetylated wood elements can be used in the production of medium density fibreboards with superior qualities such as dimensional stability and durability.

    Abstract: A method of treating an elongate wood member is provided, the wood member having an outer surface and a cross-section. The method includes (1) forming a plurality of holes into the outer surface of the wood member; (2) introducing a treatment composition which includes a boron-containing compound into the plurality of holes; and (3) steam treating the wood member for a duration of from about 15 minutes to about 24 hours, the steam having a temperature of from about 80° C. to about 150° C. The steam treatment causes the boron-containing compound to diffuse from the formed holes into the cross-section of the wood member.
