Abstract
The thermal conductivity properties of wood of Paulownia Clones in Vitro 112 were investigated after heat treatment at temperatures of 180 °C, 200 °C and 220 °C. After the treatment, the density decreased by 5.6, 8.9, and 14.1% for the samples heat-treated at 180 °C, 200 °C and 220 °C, respectively. The decrease in the thermal conductivity was 0, 2.6 and 15.7%, respectively. The thermal conductivity of kiri wood after thermal treatment at 220 °C was 0.064 W/mK, which is almost the same as that of thermal insulation materials.
Highlights
An increasing number of kiri wood (Paulownia sp.) plantations have been established worldwide in recent decades
The density decrease after the heat treatment was statistically significant compared to the initial values
The treatment at 180 °C did not produce any change in thermal conductivity, while the density decreased by 5.6%
Summary
An increasing number of kiri wood (Paulownia sp.) plantations have been established worldwide in recent decades. A 5–7-year-old tree can produce up to 1 m3 of wood material annually. The kiri tree has a wide range of possible uses: it is used to manufacture boxes, cabinets, chairs and tables, doors, windows, ceilings, and it can be used for paper manufacturing. Intensive research on its use as a biofuel and in fiberboards is taking place. Due to its rapid growth, large amounts of kiri wood will be harvested in the few decades. It is expected that the uses of kiri wood will widen and additional tests are required to reveal its properties
