Xu Boming, dean of the Shenzhen Furniture Development Research Institute, recently discussed the so-called "style" problem on the market. In fact, in China, the style is confusing. For example, in the United States, there are beautiful, small, and beautiful... these "styles" have not been heard by Americans. In the past two years, the so-called Nordic style has suddenly become popular. At the beginning, the Nordic style and modern furniture have been equated, and all modern furniture is called Nordic style. Then suddenly there appeared "Greater Nordic", which called the earth design that was stupid and stupid and whose style was not "Great Nordic". This flicker, too much? Under these so-called styles, they emphasize loudly all solid wood, pure solid wood, 100% solid wood, no accessories... It is obvious that the wood-based panel is used to call the particle board a solid wood particle board, and the plywood is called a solid wood layer. The part of the solid wood is called the sea silk, what is the wood, the rubber wood is called the oak... It's not that the wood-based board is not good, not the rubber wood. The problem is that there is no integrity. In fact, the proper combination of solid wood and wood-based panels is the best structure. I take an ordinary bedside table as an example, as shown below: The wood part is not only the material that forms the shape, but also the component of the whole piece of furniture. The wood-based panels are combined by wood. Any wood can be used, not expensive wood is good. For example, North American black walnut, very expensive, ok? The density is 0.64 g/m3, and the density of birch, which is relatively inexpensive, is also 0.64 g/m3. Black walnut is so expensive, it is only the designer's preference, leading the market. The mass consumers accepted it, so the price was speculated because of supply and demand, and nothing more. If a large area of ​​the board, the back board, the bottom board, and the side board are solidified, the problem of shrinkage and swelling will occur. It is best to use wood-based panels, of course, with qualified wood-based panels (formaldehyde and other standards meet national standards), the quality of such furniture is more reliable and durable than solid wood. The combination of wood and wood-based panels - assembly, glue, and curing with round bars and the like, is a combination of the "MiG 25 fighters" in the furniture. Xu Boming touched another topic in the article, solid wood restructuring materials. Because the wood will shrink and swell, and the market does have a demand for solid wood furniture, we need solid wood as the component of the wood furniture. Therefore, reorganizing solid wood is a very important issue. The basic requirements for solid wood restructuring are: ——avoid the natural defects of wood such as shrinkage and swelling ——Can carry out industrial production Extended reading: What factors determine the price of high-grade wood Solid wood reorganization is the first plywood, then Laminated-Veneer Lumber (LVL). However, for various reasons, the market demand has not been met, for example, the veneer is too thin. So the market has a "sandwich board", the structure is the same as the three plywood, just change the veneer into solid wood. The advantages of sandwich panels are: ——The process of drying in front is processed by the board factory, and the solid wood sheet of the board factory is relatively thin, the drying time is shortened, and the water content is relatively uniform. ——Because it is a sandwich, the wood grain in the middle layer crosses and forms a cross with the upper and lower layers. The board is firm and straight. ——The quality requirements for the middle wood chips are not so high, increasing the utilization rate of the wood. - Not like a large piece of wood, the central part has a high moisture content, and the surface gradually decreases, forming a gradient. If the drying is not good, the stress of the surface layer and the middle and lower layers will cause cracking, and the sandwich board will not. Reorganizing the wood, whether it is a sandwich board or other combination, can achieve solidification production. The reconstituted wood can be made into various sizes suitable for automated production, and can even be made into 1220 mm × 2440 mm. The plate-type equipment and plate-type production are greatly improved, and the labor is reduced. Of course, reconstituted wood cannot replace 100% solid wood, but it can solve many of the natural defects caused by (or have to use) solid wood. This topic has the opportunity to be discussed in depth.

Height Adjustable Drafting Table A height adjustable drafting table is a specialized table used by architects, engineers, artists, and designers for drawing, sketching, and drafting. It typically has a large, flat surface that can be tilted to different angles to provide a comfortable working position. The surface is often made of wood or metal and may have a ruler or straightedge attached to it for precise measurements. Drafting tables may also have drawers or compartments for storing drafting tools and supplies. They are designed to provide a stable and adjustable surface for creating detailed drawings and plans.
