- Abstract
Wood is an organic material, heterogeneous and hygroscopic which may present dimensional variation and deformation due to environment interaction. When moisture equilibrium between wood and atmospheric air is reached, in use or during drying, it is wood equilibrium moisture content (EMC). The wood presents high importance as raw material for Mato Grosso State. Them it becomes necessary to know the seasonality of the EMC. This study aimed to estimate the wood EMC by Simpson model for 30 cities in Mato Grosso State, Brazil, located in different regions of the socioeconomic and ecological zoning. Meteorological data from 2006 to 2012 were obtained from Automatic Weather Stations Network of the National Institute of Meteorology. EMC was estimated on daily databases to obtain monthly averages. EMC varied between 5.08 to 9.57% and 8.58% to 13.49% in the dry and rainy season, respectively. The higher EMC was observed from January to March. Wood dries naturally and faster due to environmental condition during dry season (June to September).
