Due to the use of wood processing, while big surface area and less fixed points, so it is one of the most prone to deformation and cracking of the decorative items. In addition, the deformation of the wooden doors will directly affect the sound insulation, airtight and beautiful, so to understand the deformation of the wooden doors of the decoration is a particularly important decorative knowledge.
Natural wood is the influence of various factors in the growth process, leading to the wood unevendensity (adret, ring density, core material, wood and sapwood), after being dug they changed the stress balance, the wood will deformation and cracking.
High moisture content of wood is also a major cause of the deformation, with reduced moisture in the process, stresses in the wood will slowly revealed, eventually leading to deformation and cracking.
Main means of preventing deformation is changed internal stress and water content by mechanical and technical methods. The most effective and commonly method is joint the pine or fir (both less stress in wood). Changing moisture content of wood is a secondary drying (steam drying after natural drying). Wooden door production and processing technology, such as pressure, temperature, compressor balance layer, glue and other factors will have a direct impact in the wooden door deformation and cracking.
