The moisture content of lumber is referring to the wood by the percentage of the water quality of wood drying quality, wood water absorption ability is very strong, its moisture content changes over their environment, moisture content, free water, the adsorption of water, bound water of three parts. Affect the physical properties and application of wood fiber is the main water-bearing index saturation and equilibrium moisture content.
Equilibrium moisture content refers to a balanced absorption and volatilization of moisture in wood moisture content. Equilibrium moisture content varied from region. In northwest and northeast of about 8%, 12% of north China, 18% in Yangtze river basin, the south is 21%, provisions in China standard to the moisture content of 15% strength value as standard
