The effects of heat treatment on some mechanical properties of laminated black pine (Pinus nigra)
Black pine (Pinus nigra) has high industrial usage potential and large plantation in Turkey. Larch wood was treated with heat to determine its mechanical properties, such as bending strength and pressure and order to determine its adhesion strength. Laminating adhesives are used for the construction of polyvinyl acetate and polyurethane. Heat treatment was applied to the samples at 100-150°C for 4 h in drying oven. In the result of the experiments, heat treated samples give better results due to temperature increase.

The investigation of heat treatment with water-based varnish double components in varnish applications of wood material.
In this study, the effects of heat treatment of wooden materials on hardness, brilliance and resistance of stick of varnishes were investigated. For this purpose, firstly Scotch pine (Pinus sylvestris L.) and chestnut (Castanea sativa M.) wooden samples were kept in temperatures of 100, 150 and 200°C for times of 2, 4 and 6 h and after that they were varnished by the water-based varnish. According to test results, it was determined that while the hardness, brightness and resistance of stick were improved for both wooden types which were kept for 2 h in temperatures of 100, 150 and 200°C, they deteriorated for both wooden types kept for 4 and 6 h in same temperatures.
Adhesive bonding of acetylated aspen flakes Part 3. Adhesion with isocyanates
Abstract Flakeboards made from control flakes bonded with an isocyanate resin outperformed phenolic-bonded control boards in thickness swelling tests in both liquid water and water vapour. Less irreversible swelling occurred in isocyanate-bonded control boards as compared to phenolic-bonded control boards. Flakeboards made from acetylated flakes, using either a phenolic or isocyanate resin, swelled in thickness much slower and to a lesser extent in liquid water and water vapour tests compared to control boards. Isocyanate-bonded control and acetylated aspen flakeboards had higher internal bond and modulus of rupture values and approximately equal modulus of elasticity properties when compared to a similar series of boards bonded with a phenolic resin, as reported in Part 1 of this series.
