Previous issue date: 2012-06-29 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Heat treatment provides desirable characteristics to the wood such as higher dimensional
stability, higher natural durability and, in some cases, changes on original color. However, the
treatment can also drastically alter the physical and chemical characteristics of wood surfaces,
which affect the adhesion quality and coating application. In this context, the objectives of
this study were: (1) to evaluate the effect of heat treatmens on physical properties (density,
equilibrium moisture content and mass loss) of Corymbia citriodora (Hook.) K.D. Hill &
L.A.S. Johnson and Eucalyptus pellita F. Muell. woods; (2) to determine the effect of heat
treatment on color change of both woods; (3) to evaluate the effect of heat treatments on
adhesion quality of glued joints by shear strength testing; and (4) to evaluate the effect of
physical and chemical modifications following heat treatment on adhesion characteristics.
Heat treatments were performed in a laboratorial electric oven at 180 and 200?C. Color
measurements were carried out on the CIE-L*a*b* space by using the CM-2600d portable
spectrophotometer. Shear strength tests of the glued joints and solid woods were performed
according to ASTM D 905 and ASTM D 143 standards, respectively. Three adhesive types
were used: resorcinol, resorcinol-tannin 80:20 and resorcinol-tannin 60:40. Density and
equilibrium moisture content of both wood species were reduzed by heat treatment. Both
woods had mass loss, which increased with the increase of temperature and was more
pronounced for Eucalyptus pellita. The original color of the woods changed following heat
treatment, mainly to Eucalyptus pellita. The shear strength of solid wood and glued joints of
both species was severely affected by heat treatments. The resorcinol-tannin 80:20 adhesive
showed the best performance for untreated woods, however, after heat treatment, the adhesive
type did not affect the shear strength. Glued joints of heat-treated woods had high percentage
of wood failure due to higher porosity and adhesive penetration. The acidity of heat-treated
woods affected the shear strength and presented a strong correlation with equilibrium
moisture content due to degradation of hemicelluloses. Heat treatments at 180 and 200oC are
extremely severe to Corymbia citriodora and Eucalyptus pellita woods / O tratamento de termorretifica??o proporciona ? madeira caracter?sticas desej?veis tais como
maior estabilidade dimensional, maior durabilidade natural e, em alguns casos, altera??o da
cor original. Entretanto, o tratamento tamb?m pode alterar drasticamente as caracter?sticas
f?sicas e qu?micas das superf?cies da madeira, as quais afetam a qualidade de ades?o e a
aplica??o de revestimentos. Neste contexto, os objetivos deste estudo foram: (1) avaliar o
efeito dos tratamentos nas propriedades f?sicas (densidade, teor de umidade de equil?brio e
perda de massa) da madeira de Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Johnson e
Eucalyptus pellita F. Muell.; (2) determinar o efeito dos tratamentos termorretificadores na
altera??o da cor da madeira de ambas as esp?cies; (3) avaliar o efeito dos tratamentos na
qualidade de ades?o de juntas coladas atrav?s de testes de resist?ncia ao cisalhamento; e (4)
avaliar o efeito das altera??es f?sicas e qu?micas causadas pela termorretifica??o nas
caracter?sticas de ades?o. A termorretifica??o foi realizada em um forno mufla el?trico
laboratorial a 180 e 200?C. As medi??es de cor foram realizadas no espa?o CIE-L*a*b* com
o aux?lio do espectrofot?metro port?til CM-2600d. Os ensaios de cisalhamento das juntas de
madeira colada e das madeiras s?lidas foram realizados segundo as normas ASTM D 905 e
ASTM D 143, respectivamente. Foram utilizados tr?s tipos de adesivos: resorcinol,
resorcinol-tanino 80:20 e resorcinol-tanino 60:40. A densidade aparente e o teor de umidade
de equil?brio das madeiras de ambas as esp?cies foram reduzidos pela termorretifica??o.
Ambas as madeiras apresentaram perda de massa, sendo esta crescente com o aumento da
temperatura e mais acentuada para a madeira de Eucalyptus pellita. A cor original das
madeiras foi alterada pelo tratamento, principalmente para o Eucalyptus pellita. A resist?ncia
ao cisalhamento da madeira s?lida e das juntas coladas de ambas as esp?cies foi severamente
afetada pelos tratamentos termorretificadores. O adesivo resorcinol-tanino 80:20 apresentou o
melhor desempenho para as madeiras n?o termorretificadas de ambas as esp?cies; entretanto,
ap?s a termorretifica??o, o tipo de adesivo n?o afetou a resist?ncia ao cisalhamento. As juntas
coladas das amostras de madeiras termorretificadas apresentaram uma alta porcentagem de
falhas na madeira devido ? maior porosidade e maior penetra??o do adesivo. A acidez das
amostras da madeira termorretificada afetou a resist?ncia ao cisalhamento e apresentou uma
forte correla??o com o teor de umidade de equil?brio devido ? degrada??o das hemiceluloses.
Os tratamentos termorretificadores a 180 e 200?C s?o extremamente severos para as madeiras
de Corymbia citriodora e Eucalyptus pellita
