Abstract

The objective of this study was to evaluate the efficiency of a preservative treatment with Chromated Copper Borate (CCB)
in different concentrations and autoclave pressure time on the biological resistance of Eucalyptus urophylla x Eucalyptus
grandis (called urograndis). Urograndis fence posts were submitted to industrial autoclaving in nine treatments as a
function of CCB concentration and pressure time: 1.5% (30, 60 and 90 minutes); 2.0% (30, 60 and 90 minutes); and
2.5% (30, 60 and 90 minutes). Then the obtained specimens were submitted to an accelerated laboratory decay test. The
industrial preservative treatment increased the resistance of the wood to decay and the concentration of 1.5% CCB and
30 minutes of autoclave pressure can be applied to treat urograndis wood without compromising its resistance to
the attack of white-rot and brown-rot fungi.

Keywords: Accelerated decay test, CCB concentration, autoclave pressure time.  aMADEIRA  aRESISTÊNCIA  aCOBRE  aINSETO XILÓFAGO0 02929dRio de Janeiro-RJ Instituto de Florestas - UFRRJ 1994o2025-0458tFloresta e Ambiente (Brazil)x1415-0980  /  ISSN 2179-8087 0nlinegv. 27(4) p. 1-6; (2020)wBR2026001907  uhttps://www.scielo.br/j/floram/a/CLdtYJdfrVCjzqfmWPvPxQB/?format=pdf&lang=en
