The wooden door is one of the most decorative woods that are most prone to deformation and cracking due to the use of wood processing, large flat area, and few fixed points. Since the deformed wooden door will directly lead to the sound insulation, airtightness and beauty of the house, it is of great importance to understand the deformation of the wooden door.
Natural wood has various factors in the growth process, resulting in uneven wood density (sunny surface, annual ring density, core material and sapwood). When the wood is shaved, the internal stress balance is changed. Deformation and cracking of wood.
The high moisture content of wood is another major cause of deformation of the wooden door. As the water content decreases during use, the internal stress of the wood will slowly appear, eventually leading to deformation and cracking.
The main means of preventing wood deformation is to use mechanical and technical methods to change the internal stress and water content of the wood. The most effective and most common way to change 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). The quality of the processing 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.
