摘要： Disclosed is a bamboo strip shaping method, which includes the following steps: S01: cutting a bamboo tube, and removing inner joints, outer joints and bamboo outer skin; S02: trisecting or quartering the bamboo tube in a longitudinal direction to obtain curved bamboo strips; S03: placing the curved bamboo strips in a bamboo strip shaping device for processing; S04: subjecting the curved bamboo strips to steam treatment and heating softening treatment; S05: pressing and shaping the curved bamboo strips to obtain flattened bamboo strips, and drying for a first time under a maintained pressure; S06: wetting bamboo outer skin surfaces and bamboo inner skin surfaces of the flattened bamboo strips, and drying for a second time; and S07: wetting the bamboo outer skin surfaces and the bamboo inner skin surfaces of the flattened bamboo strips, and drying for a third time.

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.
