Özet

Wettability of medium density fiberboard (MDF) surface affects paint or adhesive application and is, thus, of importance in the course of furniture manufacturing. This study investigated the effects of wood species, digester conditions and defibrator disc distance on the wettability properties. It was found that the wettability of the MDF significantly decreased with increasing the defibrator disc distance and increased with the increment in the severity of the digestion conditions. The highest wettability was found for samples made of beech wood having an average contact angle value of 74.5 degrees, followed by poplar wood (76.5 degrees), birch wood (79.7 degrees), the mixture (1:1) of scots pine and beech wood (82.9 degrees), and scots pine wood (86.4 degrees), respectively.
