Accelerated and natural weathering performance of impregnated wood samples
(International Conference on Agriculture, Food, Veterinary and Pharmacy Sciences, 2017-05-15)Numerous chemicals are currently applied for wood protection against weathering. However, most of these chemicals cannot provide a long-term protection on wooden surface. Therefore, water repellent materials are needed to ... -
Accelerated weathering performance of impregnated wood samples coated with zinc by means of plasma-assisted particle deposition
(The International Research Group On Wood Protection, 2016-05-15)Many different methods are currently applied for wood protection against outdoor conditions. The most important of these is the process of impregnation with liquid substances. However, this kind of wood preservatives cannot ... -
The combined effects of copper and oil treatment onwood chemical properties
(International Forestry Symposium, 2016-12-07)Copper are among the most commonly used substances in impregnating industry due to its high toxicity against fungi at last 50 years. The performance of CCA (copper-chrome-arsenic) approved by all over the World because of ... -
Effect of heat treatment on the weathering and hardness properties of some wood species
(Northern European Network for Wood Sciences and Engineering, 2015-10-25)Thermal modification is known as a potential method to improve dimensional stabilization of wood and enhance its biological resistance. Scots pine (Pinus sylvestris), spruce (Picea orientalis), ash (Fraxinus spp.), tali ... -
Effect of tall oil pretreatment on physical and mechanical properties of heat treated fir and beech
(27th International Conference on Wood Modification and Tehnology, 2016-12-07)Thermal treatment is an environmentally friendly process and effective to improve biological resistance as well as enhance dimensional stability of wood material. However, the mechanical properties of the wood are decreased ... -
Effect of water repellents on the surface characterisation of scots pine (pinus sylvestris) exposed to accelerated and outdoor weathering
(28th International Conference on Wood Science and Technology, 2017-12-07)Numerous chemicals have been investigated to inhibit photodegradation of wood and to protect it long term against weathering in-service. However, most of these chemicals cannot provide a long-term protection on wooden ... -
Effects of boron Impregnation and heat treatment on some physical and mechanical properties of spruce and pine wood
(Karadeniz Teknik Üniversitesi, 2010-11-04)This study evaluated the effects of boron impregnation and heat treatment on some physical and mechanical properties of wood. Spruce and pine wood samples were treated with 4% aqueous solution of both boric acid (BA) and ... -
Effects of nano-zinc oxide based paint on weathering performance of coated wood
(Salzburg University of Applied Sciences, 2014-09-20)Nano-sized zinc oxide (ZnO) was chosen as a suitable candidate for the UV-protection of coatings. The accelerated weathering performances of Scots pine coated with wood paint mixed with nano- ZnO were investigated. Uncoated ... -
Improvement of fire performance of impregnated wood with copper based chemicals
(28th International Conference on Wood Science and Technology, 2017-12-07)Copper is among the most commonly used substances in impregnating industry due to its high toxicity against fungi at last 50 years. Copper-azole (CuA) and ammonical copper quaternary (ACQ) are the most widely used, because ... -
Improving the performance of scotch pine (pinus sylvestris) wood surface
(Northern European Network for Wood Sciences and Engineering, 2015-09-25)In this study, the influence of wood stain (WS) and zinc (Zn) particles applied by a plasma process at atmospheric pressure against UV light was investigated. Scots Pine (Pinus sylvestris L.) specimens were prepared from ... -
Investigation of usage possibilities dyed material from cherry wood bark in color paper production
(International Conference on Agriculture, Food, Veterinary and Pharmacy Sciences, 2017-05-15)Paper can be exposed to external influences such as mechanical, physical and biological depending on place of use. One of these effects is sunshine. When paper exposed to direct or indirect sunlight changes color. Depending ... -
Surface characterization of some woods exposed to accelerated weathering
(28th International Conference on Wood Science and Technology, 2017-12-07)In this study, the photo degradation of beech (Fagus orientalis), oak (Quercus robur), ash (Fraxinus spp.), and poplar (Populus euramericana) wood samples were investigated by accelerated weathering test in order to ... -
The effects of industrial-scale heat treatment and impregnation with boron compounds on water uptake and tangential swelling of some wood species
(2012-05-10)This study evaluated the effects of boron impregnation and heat treatment on water uptake and tangential swelling of spruce (Picea orientalis), pine (Pinus nigra), beech (Fagus orientalis) and poplar (Populus deltoides) ... -
Treatment of scots pine wood with oil in water and water in oil emulsion systems: effects on boron leaching and water absorption
(2010-10-09)The aim of this study was to investigate the water absorption and water repellent efficiency of oils and oil water emulsions [oil-in-water (O/W) and water-in-oil (W/O)] and possibilities of reducing the amount of boron ... -
Water repellent efficiency of wood treated with copper-azole combined with silicone and paraffin emulsions
(2013-01-20)Copper-azole free of chromium and arsenic is one of the potential wood preservatives against wood decay organisms being on the market as an alternative to CCA (copper, chrome, arsenic). In this study, copper-azole solution ...
