“…So far, low density particleboards and MDF have been manufactured from the wood of the following species: birch, beech, spruce, poplar, pine, shorea, balsa, Keruing, cypress, Cunninghamia, Japanese cedar or paulownia (Clad 1982, Kawai et al 1985, 1986, Suda et al 1987a, Suda et al 1987b, Suematsu and Okuma 1988, Suematsu and Okuma 1989, Chen and Wu 1993, Qiaoi et al 2000, Clad and Pommer 1980, Kalaycioglu et al 2005, Borysiuk et al 2007). …”

The study investigated the possibility of using rape straw and expanded polystyrene for the production of low density particleboards. Particleboards with the core layer made of wood chips or rape straw, partly substituted with polystyrene (7%), were manufactured within the density range of 500 -650 kg/ m 3 , and resinated with MUF resin. Our study confirmed that wood chip-expanded polystyrene (WP) and wood chip-rape straw-expanded polystyrene boards (WRP), of density reduced to 600 kg/m 3 , met the mechanical requirements of the subject standard for boards intended for interior design (including furniture) and used in dry conditions. However, further density reduction required an increased resination of the core layer.

Besides the continuously increasing demand for wood, the significant increase in its price also contributes to the increasingly broader use of fast-growing wood species and cultivars. Newer variants are continue to be cross-bred as a result. In case of a new variant within a species, it is questionable how it would adapt to a particular climatic environment and the quality of wood it would yield. The characteristics of the Paulownia tomentosa (Robust4) wood obtained from Hungarian plantations of are generally identical to those of the Paulownia tomentosa. The value of the air dry density -as typically for paulownia species-are very low i.e. 273 kg/m 3 . Its strength values (compressive strength: 9,6 MPa; tensile strength: 39,3 MPa; bending strength: 41,7 MPa; modulus of elasticity: 4116 MPa; impact bending strength: 1,4 J/cm 2 ) also reach, and in some cases, exceed those of the Paulownia tomentosa (Thunb.) Steud. and the Paulownia Clone in vitro 112 variant. Based on these, we can expect the same wood quality from the Robust4 version as from the other paulownia variants.

“…Referring to Flynn and Holder (2001) and Clad and Pommer (1980), Akyildiz and Kol (2010) indicated that paulownia wood is used for a variety of applications such as furniture, construction, musical instruments, shipbuilding, aircraft, packing boxes, coffi ns, paper, plywood, cabinetmaking, and molding.…”

Examining Parameters of Surface Quality Performance of Paulownia Wood Materials Modified by Thermal Compression Technique

The aim of this study was to evaluate the effect of thermal compression process on some surface properties of paulownia solid wood materials. The widest surface of wood samples was mechanically compressed at high temperatures. The duration was 45 min. Four different process combinations were created, including two temperatures (150 °C and 170 °C) and two pressure levels (20 bar and 22.5 bar). The surface roughness, wettability and color properties of treated and untreated samples were compared. The roughness properties, both parallel and perpendicular to grain direction, were determined according to JIS B 0601:1994 standard. The contact angle changes of water dripped to the surface were measured according to time. For color properties, a spectrophotometer was used according to CIE L*a*b* system. The color changes were classified according to a grading method from literature. The most remarkable results on wettability were observed. The contact angle values significantly increased with this method. Although higher temperature increased the contact angle values, higher pressures did not change the values. When the surface roughness values were generally considered, this technique could decrease the values up to 40 % ratio according to the control group. Only the combination of 150 °C and 20 bar did not significantly change the values. Lastly, the results of color properties showed that all treatment parameters significantly affected total color change values of samples. Grading results were similar and the color change of modified samples graded as the lowest color difference, except with the combination of 150 °C and 20 bar. The combination of 170 °C and 22.5 bar (highest treatment conditions) significantly changed all color characteristics of samples, except b* parameter. The results of this research showed that mechanical thermal compression method could change surface properties of this fast-growing species.
