Abstract

The use of heat-treated wood
material and eco-friendly impregnation chemicals are steadily increasing in the
woodworking industry over the last decades. In this study, the effects of applications
of impregnation and heat treatment on combustion properties of Hornbeam (Carpinus betulus L.) wood were
investigated. The test specimens were impregnated with Imersol-aqua (Ia) and
Timbercare-aqua (Ta) impregnation material according to ASTM D 1413-76
standards. Impregnated specimens were subjected to heat treatment at 150, 170
and 190 °C for 2 h. The temperature of flame source combustion, the temperature
of without flame source combustion and varying light intensities (Lux)
depending on the smoke production in these combustion stages were determined
according to ASTM E 160-50. According to the test results, the highest
combustion temperature of flame source combustion was determined in
unimpregnated and heat-treated samples at 190 °C, while the highest combustion
temperature of without flame source combustion was determined in impregnated
with Ta and heat-treated samples at 170 °C. The highest light density in flame
source combustion phase was determined in unimpregnated and heat-treated samples
at 190°C, while in without flame source combustion was in unimpregnated and
heat-treated samples at 170°C. As a result, as the heat treatment temperature
increase, the combustion temperature increased and the smoke density decreased.
In addition to impregnation materials increased the smoke density while reduced
the combustion temperatures of test specimens.
