Panel furniture needs to be dried when it is processed and manufactured. The same is true for furniture panels. Cracks will appear during drying treatment, which has a great impact on the later use effect. What is the reason?
The reason for this phenomenon is that the water conductivity of the wood along the grain direction is much greater than that of the horizontal grain direction. When the wood is dry, the evaporation of water from the end face is much faster than that from the side. The moisture content of the end is lower than that of the middle, and the shrinkage of the end is limited by the wood in the middle. Tensile stress is generated at the end, and when the tensile stress exceeds the tensile strength of the transverse grain of the wood, the end face is cracked, resulting in the generation of cracks.
Controlling the temperature and moisture content during drying is the key point. Of course, the production process and the quality of raw materials are also one of the reasons for this phenomenon, which requires the manufacturer to have rich technology and experience in this link. In order to choose the surface of the board without cracks, cracks, knots, leather, etc., it is necessary to recognize the quality of the smart furniture board, which needs to be decided according to our needs.
