Isothermal Water Vapor Adsorption Process in Kiln Dried Red Oak
Introduction Dried wood often picks up or loses moisture from its surroundings during storage and use. Wood weight change does not stop until the wood reaches the equilibrium moisture content, which is a function of the surrounding environments temperature and relative humidity. However, water vapor sorption process in wood never stops because the sorption process is a dynamic balance between adsorption and desorption. The dynamic balance between adsorption and desorption is often disturbed due to temperature and relative humidity fluctuations. Wood products, which reach equilibrium moisture content, will not exhibit major problems due to swelling or shrinking if the change of temperature and relative humidity is within in a small range. Unfortunately, wood products are sometimes exposed to dramatic fluctuations in environment temperature and relative humidity during storage, transportation and use. Therefore, it is necessary to explore and understand water vapor sorption process in order to effectively control it.
