ABSTRACT: The use of wood has been considered for a long time
and to this day, it has a special place in human life. Modification of wood and
lignocellulosic materials is done by various methods, including modification of
physical, mechanical, chemical and thermal, that as a new technology, it leads
to the improvement of their undesirable features. Among these methods, heat
correction is a useful method to improve dimensional stability and leads to
increased resistance to water absorption and decay. The main purpose of this
study is to investigate the titanium Nano oxide and heat treatment on the
physical properties of hornbeam species. Samples were saturated with titanium
Nano oxide solution at a concentration of 5000 ppm and pressurized 7 times in a
pressure tank. The samples were divided into three groups: control, heat and
Nano thermal treatment. Heat and saturated samples with titanium Nano oxide
were heat treated at three temperature levels of 150℃, 175℃ and 200℃ for 4 and 6 hours. All three groups
underwent physical tests. Heat and Nano thermal oxide treatments led to reduced
water absorption and thickness swelling. Comparison between heat and Nano
thermal treatment showed a further decrease in water absorption and thickness
swelling in Nano thermal samples.
