Understand the basic knowledge of wood drying
Wood drying refers to the process of using external energy to convert water in wood into steam and expel it. The drying of wood can be divided into two categories: natural drying and artificial drying.
The most important thing when choosing solid wood furniture is to consider the intrinsic quality of the furniture, which is the issue of drying the wood. The control of the moisture content of wood is a problem that people cannot see and easily overlook when choosing furniture, and this directly affects whether the furniture will deform and crack. If the drying equipment is not good and the moisture content control is not in place, even if the shape of the furniture is beautiful and the workmanship is fine, it is difficult to ensure that the furniture will not deform or crack. Therefore, most small manufacturers produce panel furniture instead of solid wood furniture.
What should the moisture content (weight) of wood reach? This is mainly determined by the average air humidity in the region. Only when the moisture content of the board is balanced with the humidity of the outside air, can the stability of the furniture be ensured, and deformation and cracking will not occur. The average moisture content of the air varies in different regions, with an average of 10% in the north and 16% in the south. The country has formulated regulations to control the moisture content within 12% as qualified based on the differences in air moisture content between the north and south. Due to the high moisture content in the air, furniture produced in the south is difficult to adapt to the climate in the north. It can shrink by 0.5-1.5mm every 10 centimeters, making it unsuitable for use in the north and prone to deformation and cracking. The average moisture content of the air in North China is closest to the national standard for wood moisture content.
