Rozměrová stabilizace lisovaných dřevěných dílců
 Karásek, Lukáš
This diploma thesis deals with wood plasticization using microwave (MW) radiation for wood densification purposes. In this work, the literary sources of the investigated issue were summarized. The experiment was carried out on test samples of white poplar (Populus alba) with dimensions of 190 x 40 x 30 mm. Microwave plasticization was carried out by passing through a microwave laboratory line at a power of 1.5 kW and a conveyor speed of 0.1 m/min. After plasticization, the test samples were compacted in compression molds by a press by 50%. The compacted test samples were stabilized in compression molds at a temperature of 103°C for 7 days. Using heat modification at 180°C and 200°C improved moisture resistance and reduced swelling. The samples were subjected to density profile analysis to evaluate the plasticization quality.
