Effect of temperature of thermo-mechanical treatment of pine wood (Pinus sylvestris L.) veneers upon gloss and wettability. The aim of investigations was determination of gloss and wettability of pine wood veneers after thermo-mechanical treatment. Rotary cut veneer sheets of pine wood and moisture content of 5% were chosen for the experiments. In laboratory hydraulic press was densification at temperatures of 150, 180, and 210°C, pressure 3 MPa, and time 3 min. Gloss of veneers was determined with the photoelectric method with PICO GLOSS apparatus. Wettability measurements were performed microscope methods with the goniometric equipment. It was stated, that temperature of thermo-mechanical treatment influenced on the course of gloss and wettability.
