- Abstract
This study was carried out to determine the effects of some production factor such as adhesive ratio, pressing time and press pressure on thermal conductivity of oriented strand board (OSB). For this purpose, 80mm long strands made of Scots pine (Pinus sylvestris L.) were bonded with phenol-formaldehyde resin at three different ratios (3, 4.5, and 6%) to produce three-layer cross-aligned OSBs. Strands used for the production of OSB panels were produced 40% of core layer and 60% of outer layers. The panels were pressed for three different pressing times, from 3, 5, to 7 minutes, and three different pres pressure, from 35, 40, to 45, aiming for a target density of 0.70 g/cm3. The thermal conductivity test was performed based on ASTM C 1113-99 hotwire method. The lowest thermal conductivity of 0,129 W/mK was obtained from 1 sample. The highest thermal conductivity of 0,170 W/mK was obtained from the number of 26 samples. Consequently, the results of experimental study were showed that as increasing adhesive ratio, and press pressure and pressing time the thermal conductivity of samples were increased.
