Several reasons for deformation of wooden doors

The deformation of wooden doors may be caused by many factors. Because wood is used for processing, with large plane area and few fixed points, wooden door products are also one of the most easily deformed and cracked decorative wood products. The deformation of wooden doors will directly affect the sound insulation, sealing effect and beauty of the house, so understanding the causes of deformation has become a homework that must be done before decoration.

The natural wood of wooden doors in Wei Zi is influenced by various factors during its growth, resulting in uneven wood density (sunny surface, annual ring density, core wood and sapwood). When wood is planed, the balance of internal stress is changed and the wood is deformed and cracked.

The high moisture content of wood is another main reason for the deformation of wooden doors. With the decrease of water content in use, the internal stress of wood will gradually appear, which will eventually lead to deformation and cracking.

Several factors leading to the deformation of wooden doors

Whether the design structure of wooden door is reasonable (including interior decoration); Whether it is produced according to the process requirements in actual production; Whether the adhesive is completely cured; Whether the transportation and placement meet the requirements; The environmental conditions of the use place are also an important reason for the deformation of wooden doors.

In the production process, the main means to prevent the deformation of wooden doors is to change the internal stress and moisture content of wood by mechanical and technical methods, and the most effective and commonly used method to change the internal stress refers to grafting pine or Chinese fir (these two kinds of wood have smaller internal stress); The method to change the moisture content of wood is secondary drying (natural drying followed by steam drying). The quality of the processing technology in the production of wooden doors, such as the pressure, temperature, balance layer and adhesion of the press, will directly affect whether the wooden doors are deformed or cracked during use.
