Abstract:

Guangxi has abundant resources plantation eucalypt wood, high temperature heat treatment can improve its disadvantages such as split, dimension stability and durability poor; but reduce it mechanical properties. So the author made a study on mechanical properties of high temperature heat treatment wood by the single factor method. The effect of temperature of heat treated on the mechanical properties heat-treated wood (plantation eucalypt) had been researched. The results indicated that with the heat treated temperature increased, the MOR and MOE of wood decreased significantly in heat treated temperature 165-210℃ range; treated wood in 220℃ compared with MOR and MOE of untreated wood, that separate was decreased by 43.18% and 35.94%. The results showed that decrease significantly used high temperature heat treatment to improve characteristics of plantation eucalypt wood, but mechanical properties decreased.
