Abstract

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
