Abstract

Background and Objectives: Wood is a natural material used in the construction of various Wooden structures. Wooden structures are weathered and surfacely damaged by outdoor exposure. Regarding the use of Wood as outdoor furniture, floorings, parquets and Wooden wallboard in Wooden houses, some properties such as hardness, scratch resistance, and Abrasion are important. In this study, the effect of accelerated Weathering on the Abrasion resistance of Populus nigra, Fagus orientalis and Quercus castaneifolia was studied. Materials and Methods: For this purpose, Wood samples were cut to standard dimensions of 2×10×15 cm (L×R×T) and the surfaces of Wood samples were coated with Linseed oil (100 ml\m2). The coated samples were kept in an accelerated Weathering machine for 2 weeks and then, by Taber test and Confocal laser microscope, the Abrasion resistance and topography of the Wood surfaces before and after Weathering were investigated. Results: The results of this study showed that, due to Weathering, the wear resistance of all Wooden species decreased and the most resistance among them was related to oak with the weight loss of 1. 7 grams. Also, the results showed that the amount of Abrasion index reduced by 28, 38, and 18 percent for poplar, beech, and oak, respectively. The lowest and highest Abrasion resistance after Weathering were related to the poplar and oak and the results of the confocal laser scanning microscopy showed that, in the poplar, beech, and oak the Abrasion depth was 201, 183, and 136 (μ ), respectively. Conclusion: The increase in oak wear resistance to other species can be due to higher specific gravity. The use of Linseed oil coating reduces water absorption, on the other hand, reduces friction and makes the surface of the Wood lubricate. In addition, the increase in weight loss after Weathering is due to the higher absorption of uncoated samples than the coated samples, which causes faster and easier destruction of the Wood structure. Based on the results of the laser microscope and wear depth study, the coating with Linseed oil has been able to reduce the wear depth and increase the wear resistance. According to the results of this study, Linseed oil can be used to increase the resistance of Wood structures to Abrasion.
