The effects of heat treatment on some technological properties in european hophornbeam (Ostrya caprinifolia Scop) wood

In this sudy, some technologic properties of heated European Hophornbeam(Ostrya carpinifolia Scop) wood was investigated.Heating wood has since ancient times been a method to dry and modify itsproperties. Nowadays heat is used in industrial processes for the same reasons.Heat treatment was applied on the wood samples at three differenttemperatures (120, 150 and 180°C) and three different durations (2, 6 and 10 hours)under atmospheric pressure (± sensitively).As physical properties; oven-dry density and swelling, as mechanicproperties; static bending strength and modulus of elasticity were determined.The results indicated that the effects of heat treatment on physical propertiesespecially with dimensional stabilization was found satisfactory. Physical andmechanic properties values generally exhibited a decrease with increasing theexposure durations and temperatures.The obtained results were analyzed using ANOVA and Duncan Test, theeffects of temperature and duration to physical and mechanical properties weredetermined. According to the results, increasing temperatures resulted more weightloss on the heat treated specimens than the control specimens. The results indicatedthat the effects of heat treatment on physical properties of specimens in regard toswelling was found satisfactory. Mechanic and technologic properties generallyexhibited a decrease with increasing the exposure durations and temperatures.
