Development of Technology for One-Sided Surface Carbonization of Wood

Original language description

One-sided surface charring of beech wood (Fagus sylvatica L.) was analyzed. Specimens were one-sided carbonized using contact heating system with a hot plate on the radial and tangential surface at various time-temperature regimes (200/250/300/350 and 400oC). The degree of one-sided carbonization and its depth from modified surface was evaluated using temperature profiles, X-ray density profile and by spectrophotometric analysis of total carbohydrates at surface layers. An average total amount of carbohydrates of reference specimens was measured to be 0.75 mg/g of dry wood mass for specimens. Significant increase of soluble carbohydrates was found within surface layers of specimens carbonized at 400oC for 1 min and decreased with increasing distance from the heated surface. An average density (680kg.m-3) of reference specimens shows uniform density profile, while one-sided carbonized specimens tended to decrease according to time-temperature regime applied. It can be stated that one-sided carbonization affected wood properties to depth 2-4 mm from the surface, depending on used time-temperature regime. The very first results of current research project shows that beech wood also exhibits favorable results in terms of surface moisture related characteristics, but more detailed studies are needed to exploit potential of surface carbonization method for future use of beech wood. The process of wood surface carbonization can be optimized according to these results, regarding to desired material properties.
