Some Technological Properties of Scotch Pine (Pinus Sylvestris Lipsky) and Eastern Beech (Fagus Orientalis Lipsky) Woods Impregnated with Alpha-X Chemical

Öz

This study was performed for the purpose of determining the technological properties of Scotch pine (Pinus sylvestris Lipsky) and Eastern beech (Fagus orientalis Lipsky) woods impregnated with Alpha-X chemicals. The impregnation solution was prepared at 10 % and 20 % concentrations. Alfa-X, a flame-retardant chemical formerly applied to textiles and laminate parquet, was used for the first time in wood work. As a result of the combustion tests, Alfa-X reduced the initial weight loss temperature of the wood material in both samples. However, it has completely raised the combustion temperature gradients in both samples. It is observed that ending temperature increased in eastern beech wood and in scotch pine wood by 117 °C and 50 °C, respectively, with increasing the rate of Alfa-X added into impregnation solution from 0 % to 20 % at deterioration. In addition, the bending and compression strength values ​​of the Scotch pine and Eastern beech wood samples were also examined
