Causes of warping of Solid Wood Poplar Lumber：
Solid Wood Poplar Lumber is one of the common panels used in furniture manufacturing. It has good practical application effects. However, warping often occurs in the application, which greatly affects the actual practical effects of normal applications. Then we will come Introduce the reasons for the warpage of the Solid Wood Poplar Lumber .
1. Solid Wood Poplar Lumber is a thin wooden material produced by rotary cutting or sawing. It is mainly used for furniture and general construction materials. It is a main raw material widely used in the processing and production of plywood composite panels. It is the core board of decorative board ecological board and is used for high-end furniture with special-shaped bent wood and solid wood imitation.
2. Solid Wood Poplar Lumber products are light in weight, clear in texture, insulated, strong, and not easily deformed. The construction is convenient, it is not suitable for warping, and the horizontal grain has good tensile mechanical properties. But for ordinary panels, poplar paneling is generally expensive. Can be customized according to customer requirements.
3. Reasons for warping of poplar panel: the structure and processing technology of poplar panel does not conform to the principle of symmetry; the moisture content of the veneer is uneven; the temperature and pressure of the panel are too high; the drying quality of the veneer is improved; the temperature and pressure are appropriately reduced .
4. In the production and processing, the moisture content of the board should be strictly controlled, and the moisture content error should be adjusted within 2%, which can reasonably and effectively reduce the shrinkage stress of the wood and the warpage of the board. The amount of glue applied should be strictly controlled. The edge banding process can be completed on the board, so that not only can the board and the board be isolated, but also the actual effect can be decorated to prevent the board from cracking and warping deformation.
Solid Wood Poplar Lumber has the advantages of light weight, high strength, good elasticity, long fiber and high content, and easy processing. Of course, poplar plywood also has such characteristics, which is the main reason why poplar plywood is so popular with everyone. It is necessary to pay attention to the strict investigation of its quality during the purchase, so as to ensure better application. Actually, the warping situation occurs.
