INFLUENCE OF COMMERCIAL THERMAL TREATMENT ON Eucalyptus grandis Hill ex Maiden WOOD PROPERTIES

ABSTRACT This study aimed to evaluate the influence of commercial thermal treatment on Eucalyptus grandis considering its physical, chemical, and mechanical properties. The wood samples were heat-treated in an autoclave with saturated steam pressure application at four different temperatures: 155, 165, 175, 185 ºC. properties altered due heat treatment. extractives content varied between 6.06% 28.75%; lignin 28.93% 37.96%; holocellulose 65.01% 38.12%. reduced significantly increase temperature. Through set data obtained, it was possible generate significant high precision regression models capable estimating such for temperatures not studied experimentally, enabling determination most suitable temperature achieve a certain property value treated wood.
