This invention relates to the field of wood processing technology, and provides a novel method for preparing slicing from the decay and softening of extra-hardwood. The method includes the following steps: immersing a wood sample in a water-filled container, first applying a vacuum, then depressurizing and maintaining the pressure for a period of time to allow liquid water to penetrate the wood cell cavities; heating the immersed sample and applying a vacuum again to cause the liquid water to boil and vaporize; extracting the sample after the bursting treatment with cold and hot water sequentially to remove extractives from the wood and reduce its decay resistance; adjusting the moisture content; treating the sample with brown rot fungi to cause decay and softening on the axial surface of the sample; soaking the sample in water and then freezing it until it is solid, followed by slicing. This invention can successfully produce slicings of extra-hardwood, providing a strong theoretical foundation and technical means for studying the structure of extra-hardwood, predicting its physical and mechanical properties, and improving its high-value-added processing and utilization.

A device and method for preventing cracking of hardwood in solid wood products are disclosed, relating to the apparatus and method used in the post-forming process of hardwood. It features a sealed chamber with walls forming a double-layered space, connected to a boiling water tank, a vacuum pump, etc. The cracking of hardwood is prevented using an "intermittent heating-vacuum (negative pressure)" method. The beneficial effects of this invention are: during the post-forming process of hardwood, this device and method significantly increases the rate of moisture movement from the core to the surface of the hardwood, substantially reducing the "higher inside, lower outside" moisture content gradient between the surface and core, thus eliminating quality problems such as surface hardening (internal cracking) during post-forming. Solid wood products manufactured using hardwood post-formed using this invention have a near-zero probability of cracking, warping, or other product quality problems in a "dry indoor environment."
