Abstract

In this study some physical characteristics of poplar (populus nigra var pyramidalis) wood, heat treated whut LINSEED OIL was investigated. For comparison of time and temperature effects on those characteristics, three temperature stages and two time levels was selected.Preparations of samples were according to ISO standards regulations. The results of this study shows significant differences in effects of treatment temperature, also insignificant differences in time effects and shows that in general to use heat treatment whit LINSEED OIL in 200 Co temperature in 4.5 hours, give the best results between six different treatments that were employed. Interaction effects between temperature and time, only was seen in WATER ABSORPTION of samples.Moisture contents of wood decreased from 6.02% in control samples to 3.91 in wood samples that treated in 220 Co for 4.5 hours. The least radial, tangential and volumetric SHRINKAGE in treated samples was seen in 200 Co temperature. Amount of wood's WATER ABSORPTION which was 117% in untreated samples was decreased to 24.94% in samples that were treated in 200 Cin this conditions improvement of ASE were, hours' \for' that showed poplar, Color changes was noticed as a qualitative parameter. reached. wood samples after all treatments become darker
