Influências do Diâmetro e Umidade da Madeira na Qualidade do Tratamento Preservativo

Abstract: RESUMOAvaliaram-se os efeitos do teor de umidade e classe diamétrica na qualidade do tratamento de moirões de Corymbia torelliana e Eucalyptus grandis x Eucalyptus urophylla. Utilizaram-se 108 moirões, sendo 36 tratados e 18 não tratados, com 2,20 m de comprimento e umidade de 15 a 20%; 20 a 30%; 30 a 40%, e diâmetros de 8 a 10 cm; 10 a 12 cm; 12 a 14 cm. No tratamento, foram utilizados 2% de ingredientes ativos de CCA-C, vácuo inicial e final de 550 mmHg (30 min), pressão de 11 kgf cm -2 (1 h). Os moirões tiv… Show more

“…As a solution, fast-growing tropical species that have a medium to low density are gradually being used more in the Brazilian timber market. However, such species are more susceptible to deterioration and require conservative treatment (Paes et al 2001;Lopes et al 2017). The main wood products in Brazil that are subject to this treatment include fence posts (with great representation in rural areas), poles, crosses, wooden crossties, and structures for civil construction (Chagas et al 2015).…”

“…The concentrations and pressure times used in this study were defined as being the parameters commonly used in the country's wood treatment plants (TORRES et al, 2011;LOPES et al, 2017). After the preservative treatment at the different concentrations and times, the fence posts were dried outdoors for 30 days for the preservative fixation.…”

“…Wood is a material of organic origin, and depending on the environmental conditions to which it is submitted it might be deteriorated by biological degradation agents (bacteria, fungi, insects), as well as by chemical reactions (LOPES et al, 2017). When used in its solid form (e.g., fence posts), the wood in contact with the soil undergoes an interaction of moisture and aeration in such context , favoring the development of fungi (VIDAL et al, 2015;SILVEIRA et al, 2018).…”
