Abstract
To increase the utilisation and the value of poplar, various concentrations of dimethylol dihydroxy ethylene urea (DMDHEU) were used to impregnate poplar, an important tree species from the north of China. The resin was fixed on the timber under certain conditions, after which the weight percent gain (WPG), flexural modulus (MOR), modulus of elasticity (MOE), impact strength, hardness and compressive strength of the poplar impregnated were tested and evaluated. The results showed that WPG of poplar is positively associated with the concentrations of DMDHEU after the resin treatment; when the WPG of poplar was 62.1% and the concentration of resin was 30%, the concentration of resin shows positive correlation with MOE, the hardness of each section, the compression strength perpendicular to grain, and the compressive strength parallel to the grain, but demonstrates negative correlation with MOR and impact strength. 12 Refs.
