China Wood Moisture Content
Wood drying refers to the process of turning the water in the wood into steam and discharging the wood by relying on the energy provided by the outside world. Drying of wood can be divided into two categories: natural drying and artificial drying.
The most important thing in choosing solid wood furniture is to look at the inherent quality of the furniture, that is, the drying of the wood. The control of the moisture content of wood is a problem that people cannot see and ignore when purchasing furniture, and this is directly related to 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 furniture is beautiful in shape and fine in workmanship, it is difficult to ensure that the furniture will not be deformed or cracked. Therefore, most small manufacturers produce panel furniture instead of Production of solid wood furniture.
What should the moisture content (weight) of the wood be? This is mainly determined by the average air humidity in the area. Only when the moisture content of the board and the outside air humidity are balanced, can the stability of the furniture be ensured without deformation and cracking. The average moisture content of the air varies from region to region, with an average of 10% in the north and 16% in the south. According to the difference in air moisture content in the north and south, the state has formulated regulations that control the moisture content within 12% as qualified. Due to the high moisture content of the air in the south, the furniture produced is difficult to adapt to the climate in the north, and can shrink by 0.5-1.5mm per 10 cm, which is not suitable for use in the north, and is easy to deform and crack. The average moisture content of air in North China is closest to the wood moisture content set by the state.
Generally, small enterprises choose earth kiln baking or entrust wood processing plants for processing. The moisture content of the board can only be controlled to about 14%, and the blind heating will make the moisture content inside and outside the board unbalanced. The quality of furniture is not guaranteed. So everyone be careful.
