摘要: ABSTRACTCuring conditions influence the properties of wood modified with melamine resin. Beech (Fagus sylvatica L.) was impregnated resin and cured in a dry hot steam process to investigate relative humidity while curing. The topochemistry assessed by light microscopy (LM) scanning electron coupled energy-dispersive X-ray spectroscopy (SEM-EDX) visualise structural chemical changes on cell wall level. LM combination staining did not show differences between curing processes but allowed distinguish untreated treated wood. SEM micrographs revealed more severe impact integrity material than formation micro cracks. Dry-cured specimens showed higher concentration steam-cured same overall distribution pattern as shown EDX line scans.
