The factors causing wood deformation is a variety of reasons, because wooden door USES wood processing, surface area, and protection, so is the most likely deformation and cracking of the decoration wood. Because of the deformed wood will directly cause the sound insulation of the building, sealing and beautiful, so understanding of wood deformation causes became adornment is decorated importantly particularly before knowledge.
Natural lumber in the growth process, the influence of various factors in lumber density inequality (to the sun, rings, core and alburnum), when the wood was open and changed the balance of internal stress, make lumber is out of shape, craze.
The moisture content of lumber is high also cause wood deformation of another primary reason, as the moisture content in use process, reduce the internal stress of lumber will gradually revealed, eventually leading to be out of shape, craze.
Wood structure design is reasonable (internal), In practical production process is required by making, Whether fully cured; cement Whether meet the requirements and transportation, Use the site conditions are the important reasons caused by deformation of wood.
Production process, the main means to prevent wood deformation machinery and technology is used to change the internal stress of lumber, and moisture content, change due to the most effective, most commonly used methods of pine or fir (are these two kinds of lumber to smaller); The method that changes lumber moisture content is the second drying (natural drying after steam drying). In the production process of wooden door, such as pressure, temperature and pressure balance layer, adhesive force will directly influence factors such as wood in use process is out of shape, craze.
