Resumo: | The strategy of wood preservative treatment companies is to control the factors that influence retention, such as the concentration of the preservative solution and wood moisture, to reach values higher and closer to the standard minimum. The objective of this study was to reduce the consumption of Chromated Copper Arsenate type C (CCA-C) without affecting the quality of the treatment by determining the most efficient wood moisture interval for two genotypes of Eucalyptus sp. at different concentrations of active ingredients. A total of 54 fence posts of the species E. cloeziana and the hybrid E. camaldulensis x E. urophylla were treated. The pieces were randomly selected from three drying piles with different storage times in the yard (long, intermediate, and short). The active ingredient concentrations tested were 1.2, 1.4, and 1.6%. Retention analysis was performed to evaluate the quality of the preservative treatment. For both analyzed materials, the lowest and highest average retention values were observed in short and long storage piles and concentrations of 1.2% and 1.6% A.I. CCA-C, respectively. For E. cloeziana, only posts with a long storage time and treated with 1.6% of CCA-C were considered suitable for use in contact with the soil, according to the Brazilian standard, while for the clonal hybrid, posts with intermediate and long storage times, treated with 1.6% of CCA-C were considered suitable for use in contact with the soil. It was observed that CCA-C retention in the studied fence posts was directly influenced by the concentration of active ingredient in the preservative solution and by the storage time of the materials in the yard. |

O objetivo deste trabalho foi reduzir o consumo de Arseniato de Cobre Cromatado tipo C (CCA-C) sem afetar a qualidade do tratamento, determinando o intervalo de umidade da madeira mais eficiente para dois genótipos de Eucalyptus sp. em diferentes concentrações de ingredientes ativos. Foram tratados 54 moirões da espécie E. cloeziana e do híbrido E. camaldulensis x E. urophylla. As peças foram selecionadas aleatoriamente a partir de três pilhas de secagem com diferentes tempos de estocagem no pátio (longo, intermediário e curto). As concentrações de ingrediente ativo testadas foram 1,2, 1,4 e 1,6%. A análise de retenção foi realizada para avaliar a qualidade do tratamento conservante. Para ambos os materiais analisados, os menores e os maiores valores médios de retenção foram observados nas pilhas de curto e longo tempo de estocagem e concentrações de 1,2% e 1,6% I.A. CCA-C, respectivamente. Para o E. cloeziana, apenas os moirões com longo tempo de estocagem e tratados com 1,6% de CCA-C foram considerados aptos para uso em contato com o solo de acordo com a norma brasileira, enquanto que para o híbrido clonal, moirões com tempo de estocagem intermediário e longo, tratados com 1,6% de CCA-C foram considerados aptos para uso em contato com o solo. Observou-se que a retenção de CCA-C nos moirões estudados foi influenciada diretamente pela concentração do princípio ativo na solução conservante e pelo tempo de armazenamento dos materiais no pátio.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorOutra AgênciaengUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASScientia ForestalisEucaliptoMadeira - PreservativosProcessamento da madeiraPreservative treatmentStorage time in the yardEucalyptusEffect of moisture and active ingredient concentration on CCA-C retentionEfeito da umidade e concentração de ingrediente ativo na retenção de CCA-Cinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://web.archive.org/web/20221222063347/https://www.ipef.br/publicacoes/scientia/v50_2022/2318-1222-scifor-50-e3919.pdfDavid Pessoa GuedesThawane Rodrigues BritoJosé Reinaldo Moreira da SilvaEdy Eime Pereira BaraúnaAnna Carolina de Almeida AndradeCarine SetterPaulo Fernando Trugilhoinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/59392/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALEffect of moisture and active ingredient concentration on CCA-C retention.pdfEffect of moisture and active ingredient concentration on CCA-C retention.pdfapplication/pdf564246https://repositorio.ufmg.br/bitstream/1843/59392/2/Effect%20of%20moisture%20and%20active%20ingredient%20concentration%20on%20CCA-C%20retention.pdfc4dd312d556497343a802f89882550efMD521843/593922023-10-11 19:02:31.665oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-10-11T22:02:31Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |

The strategy of wood preservative treatment companies is to control the factors that influence retention, such as the concentration of the preservative solution and wood moisture, to reach values higher and closer to the standard minimum. The objective of this study was to reduce the consumption of Chromated Copper Arsenate type C (CCA-C) without affecting the quality of the treatment by determining the most efficient wood moisture interval for two genotypes of Eucalyptus sp. at different concentrations of active ingredients. A total of 54 fence posts of the species E. cloeziana and the hybrid E. camaldulensis x E. urophylla were treated. The pieces were randomly selected from three drying piles with different storage times in the yard (long, intermediate, and short). The active ingredient concentrations tested were 1.2, 1.4, and 1.6%. Retention analysis was performed to evaluate the quality of the preservative treatment. For both analyzed materials, the lowest and highest average retention values were observed in short and long storage piles and concentrations of 1.2% and 1.6% A.I. CCA-C, respectively.
