Abstract

The invention discloses a process for producing dark polar wood imitating precious wood. The method comprises the following steps: stacking wood beams; transferring the wood beams into a vacuum processing cylinder; impregnating with boric acid and acetic acid solutions as processing solutions by pressurizing in vacuum; drying the wood beams subjected to vacuum-based impregnating until the moisture content is 15-22%, and then thermally pressing; thermally modifying the thermally-pressed wood beams with 0.1-0.2% of trehalose solution as a superheated steam heat-transfer medium and protective gas by the three-step method; then stopping heating; cooling; spraying steam to condition the humidity until the moisture content of the wood beams is 8 to 12%; moving out the wood beams. The polar wood produced by the process is high in transparence and saturation, and colorful, nice and high end in sense experience, and the hardness is high. The dark polar wood imitating precious wood is a new variety of modified fast-growing wood with potential market.

Description

technical field [0001] The invention relates to a production process of dark-colored poplar wood imitating precious wood, belonging to the field of wood processing. Background technique [0002] With the rapid development of economy and society, the demand for natural forest timber at home and abroad shows a rapid growth trend. In recent years, with the improvement of environmental protection awareness in all countries in the world, austerity policies have been implemented on timber exports, which further restricts the export of natural timber and further aggravates the tense situation of timber demand. The development of substitute materials for natural forest timber is an important way to alleviate the current tension between supply and demand of natural forest timber, and it is also an inevitable requirement for building a conservation-oriented society. Fast-growing and high-yield forests are currently very rich forest resources in my country. Since the end of the last c...
