Combustion properties of Scots pine (Pinus sylvestris Lipsky) wood impregnated with boron compound doped colophony

The aim of this study was to investigate the combustion properties of Scots pine (Pinus sylvestris Lipsky) wood impregnated with boron compound (borax (Na2B4O710H2O), boric acid (H3BO3) w/w 50:50%) doped colophony (C19H29COOH). For this aim, Scots pine wood samples were impregnated with boron compound doped colophony by the method of medium-term dipping according to ASTM D 1413 and producers’ definition. Combustion properties of samples after impregnated process were determined according to ASTM E 160. As a part of the research, 6 different combination and contents of impregnation materials have been used in order to especially investigate resistance against combustion of wood material treated with boron compounds in different concentrations. Consequently, retention performance and leaching resistance of boron compounds can be increased through colophony addition. Impregnation materials with colophony decreased the flame sourced combustion (Fsc) temperatures depending on kind of impregnation material, combustion period and weight loss ratio of the test samples decreased in comparison to the control samples. Colophony can be preferred in impregnation with boron compounds depending on kind of wood and using area
