Sažetak
The thin veneer strip technique was applied to investigate the modifying effects of 1, 3-dimethylol-4, 5-dihydroxyethyleneurea (DMDHEU) on the tensile strength of wood. Pine wood veneers treated with the solutions of DMDHEU and/or catalyst (magnesium chloride) showed considerable strength losses determined up to 50% in zero-span and up to 70% finite-span testing modes. The higher strength losses in the latter case are due to hemicelluloses degradation which cannot be assessed in zero-span testing. Strength loss observed after treatment with DMDHEU and MgCl2 was approximately as high as the sum of strength losses determined after individual treatments with magnesium chloride or DMDHEU. Micrographs of veneers after finite-span testing revealed that DMDHEU treatment (catalysed) changed the predominant failure mode from interfibre failure (control) to intrafibre fracture. The mechanism of strength loss due to treatment with DMDHEU is discussed.
