Description: Balance the moisture content (EMC): The wet material is placed in a dry environment, the timber the water will evaporate to the ambient air. Below the fiber saturation point, whenever the ambient relative humidity changes, the adsorption of water in the wood cell wall change. Lower the ambient air temperature, water vapor partial pressure in the cell wall than the air in the large, the evaporation of water from the timber into the air, so to reduce the adsorbed water content, the phenomenon is called desorption. The beginning of the desorption process, the wood moisture evaporation is very strong, followed by the desorption process gradually slowed, and finally a dynamic equilibrium or stability, the wood moisture content at this time called desorption stable moisture content. When the surrounding humidity is high, the cell wall of water vapor partial pressure than air and moisture, making the adsorbed water content increases, this phenomenon moisture. Wood moisture content reaches a s
