Why is the wooden door easy to deform? Due to the use of wood processing, the flat area is large and the fixed points are small, which is one of the most prone to deformation and cracking. Since the deformed wooden door will directly affect the sound insulation, sealing performance and aesthetic effect of the house, it is of great importance to understand the cause of the deformation of the wooden door.
Natural wood is affected by various factors during the growth process, resulting in uneven wood density. After the wood is cut, the balance of internal stress is changed, making the wood easy to deform and crack. The high moisture content of the wood will also cause the deformation of the wooden door. As the water content decreases during use, the internal stress of the wood will gradually appear, eventually leading to deformation and cracking. The main means of preventing wood deformation is to change the internal stress and water content of the wood by mechanical and technical methods. The most effective and most common method for changing the internal stress is to finger-join the pine or Chinese fir (the two types of wood have less stress). . The method of changing the moisture content of the wood is to perform secondary drying (natural drying followed by steam drying). At the same time, the quality of the processing technology in the production of wooden doors, such as pressure, temperature, balance layer, gluing and other factors of the press will directly affect whether the wooden door is deformed or cracked during use.
