    摘要： 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.

    摘要： The present invention implements a method to produce stained oak, having features identical or very close to a bog (black) oak wood found in wetlands. This method is based on the reaction of iron with the tannin present in the wood, and it comprises the following steps: placing the wood blank into a metal container; filling the container with water (or other suitable solvent), so that all the blanks are submersed; blending iron oxide into the solvent and producing the solution of iron oxide of a suitable concentration; heating the container to the desired temperature between 60 to 100 degrees Celsius; maintaining the temperature of the container for a certain period of time, depending on the dimensions of the blanks; compensating the water that was lost during the process due to evaporation by adding an additional amount of water; after the determined period of time or when the desired shade of wood (black, gray, blue, purple, or brown) is achieved and/or the desired density is reached; stopping the heating process and discharging the water from the tank; washing the blanks; drying the blanks in sawdust or using other desiccation means; and/or drying the blanks in convection or vacuum dryer, or using other similar means, until a needed moisture content is reached.
