Resumo: 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).

Em uso ou nos processos de secagem, quando são atingidos os equilíbrios entre a madeira e o ar atmosférico, têm-se a obtenção da umidade de equilíbrio da madeira (UEM). Em função da elevada importância dessa matéria-prima para o Estado de Mato Grosso, torna-se fundamental conhecer a sazonalidade de UEM. O presente trabalho objetivou estimar a UEM da madeira, pelo modelo de Simpson, para 30 municípios do Estado de Mato Grosso, distribuídos nas diferentes regiões de planejamento do Zoneamento Sócio-Econômico Ecológico do Estado. Os dados meteorológicos foram obtidos da Rede de Estações Meteorológicas Automáticas do Instituto Nacional de Meteorologia, entre 2006 e 2012. A UEM foi estimada diariamente, com posterior obtenção das médias mensais. Na estação seca ocorreram variações da UEM entre 5,08 e 9,57% e no período chuvoso entre 8,58 e 13,49%. Nos meses de janeiro, fevereiro e março ocorrem os maiores valores de UEM no estado. As condições ambientais durante o período seco (julho a setembro) favorecem a secagem natural da madeira serrada, por condicionarem uma secagem mais rápida.Embrapa Florestas2016-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/81110.4336/2016.pfb.36.88.811Pesquisa Florestal Brasileira; v. 36 n. 88 (2016): out./dez.; 423-433Pesquisa Florestal Brasileira; Vol. 36 No. 88 (2016): out./dez.; 423-4331983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/811/535Copyright (c) 2016 Adilson Pacheco de Souza, Diego Martins Stangerlin, Rafael Rodolfo de Melo, Eduardo Morgan Ulianahttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSouza, Adilson Pacheco deStangerlin, Diego MartinsMelo, Rafael Rodolfo deUliana, Eduardo Morgan2017-04-28T14:13:33Zoai:pfb.cnpf.embrapa.br/pfb:article/811Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T14:13:33Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
