Deterioração da madeira de Eucalyptus e Corymbia em ensaio de campo

Abstract: RESUMO A durabilidade natural da madeira é essencial na definição do seu uso. Assim, objetivou-se avaliar a deterioração ao longo de 12 meses da madeira tratada e não tratada de Corymbia citriodora, Eucalyptus camaldulensis x Eucalyptus grandis, e Eucalyptus camaldulensis em ensaio de campo. Os materiais de 5 anos, confeccionados em toretes de 40 cm de comprimento, foram tratados com Arseniato de cobre cromatado (CCA tipo C), e tiveram massa inicial determinada a 0% de umidade. Sequencialmente, foram instalado… Show more

“…With regard to extractive compounds, these are substances present in plants associated with metabolic functions and defense and protection mechanisms (Hassan et al 2017, Valette et al 2017. According to Quintilhan et al (2018), extractives are present in greater concentration in the outermost layers of the heartwood, and in adult wood, the extractives in the inner part of heartwood decrease its toxicity against invasive organisms. However, its quantity in the wood is not the predominant factor in the resistance response.…”

“…Furthermore, technological advances are increasing the possible uses of wood, such as in composites, with improved performance. (Quintilhan et al 2018), a factor that can limit the use of wood in different service conditions, especially in tropical countries (Medeiros Neto et al 2020). Both climatic conditions and xylophagous organisms can act severely in tropical conditions, thus significantly accelerating the damage and deterioration of this biomaterial (Sundararaj et al 2015, Medeiros Neto et al 2020.…”

“…Todavia, esses usos, em geral, caracterizam-se pela exposição da madeira ao ambiente e demandam o conhecimento da sua capacidade de resistir a diferentes intempéries. Nessas situações de exposição, a deterioração da madeira pode gerar comprometimento das suas propriedades físicas, químicas, mecânicas e estéticas, podendo ser resultantes da ação de agentes xilófagos (insetos, microrganismos e brocas marinhas) e das condições ambientais (exposição à radiação solar, chuva, variações de temperatura e umidade relativa do ar), além de reações químicas diversas (STANGERLIN et al, 2013;RIBEIRO et al, 2014;ROMANINI et al, 2014;QUINTILHAN et al, 2018).…”
