Abstract

Surface characteristics, wettability and surface roughness, and surface hardness of medium density fiberboards containing cone flour of stone pine (Pinus pinea L.) at various ratios (0%, 10%, 20%, 30%, 40%, or 50%) based on the oven-dry weight of wood fiber were evaluated. Contact angle measurements were obtained by using a goniometer connected with a digital camera and computer system. Roughness measurements were taken from the sanded specimens along and across the sandmarks using a fine stylus tracing technique. The results revealed that the surface quality of the panels and surface hardness reduced with the increasing cone flour content. The samples made from 100% wood fiber had the lowest contact angle value with 88.8 degrees and average roughness (R(a)) with 5.2 mu m while the highest contact angle and surface roughness were found for the samples containing 50% cone flour having value of 114.4 degrees and 9.6 mu m, respectively. Although panel type A made from 100% wood fibers had the best roughness and wettability, panel type B containing 50% cone flour had similar values to panel type A. This study revealed that value-added MDF panels containing 10% the cone flour can be used to manufacture laminated flooring and overlaid panels for the furniture industry.
