Technical introduction
This achievement has made an innovative breakthrough in selective physical compression technology, which can selectively compress and strengthen the part that needs to be strengthened, while the remaining part still maintains the inherent natural characteristics of wood, and the position and thickness of the compression layer can be arbitrarily adjusted according to needs. . Compared with the overall compression, the compression rate is reduced by more than 70%, the density of the compressed layer can reach more than 1.0g/cm³, and the hardness can be increased by more than 2 times, which greatly improves the quality of low-density wood, and the product is environmentally friendly, lightweight, and dimensionally stable. high advantage.
economic index
(1) The compression layer can be formed on the surface layer or any layer in the thickness direction of the wood;
(2) The density of the compressed layer is above 0.9g/cm³, and the rest of the layers are not compressed (the density is close to the control);
(3) The thickness of the compression layer can be adjusted arbitrarily;
(4) When the compression layer is located on the surface layer, the surface density of the compression layer can reach more than 1.8 times that of the control material, and the hardness can reach more than 2.4 times that of the control material.
(5) Layered compression technology is a physical modification technology, and the modification process is completed under hydrothermal control, without chemical pollution.
Product competitiveness and market prospects
The solid wood layered compression enhancement technology is suitable for all low-density wood. After modification, the performance of the material is improved, so that the original wood with low density, soft material, and poor dimensional stability has excellent processing performance and performance. It is directly used in the processing and manufacturing of high-quality solid wood furniture, floors, and other wood products. my country has abundant wood resources of plantation forests, and there is a strong market demand for environmentally friendly materials without chemical additions. The project has broad market application prospects.
