Maintaining Moisture Content Conditions during Lumber Storage.

摘要

After lumber has been kiln dried, it is often placed in storage, unstickered, until ready for use. If storage periods are short (up to 1 month) and the storage building is kept closed most of the time, little change in moisture content will occur. However, in many cases dry lumber is stored for several months or longer in buildings not designed to maintain a fixed equilibrium moisture content (EMC) condition. In some arid regions of the United States, such as Arizona, New Mexico, and southern California, unheated dry storage will hold dried lumber at a low EMC condition. However, in the rest of the country, unheated dry storage will not prevent kiln-dried lumber from gradually increasing in moisture content.
