Effect of densification of heat-treated brutian pine (Pinus brutia Ten.) wood on some physical, mechanical and chemical properties
In the present study, heat-treatment was applied to brutian pine (Pinus brutia Ten.) wood samples at 120, 160 and 200oC, and then the samples were pressed in the ratio of 25% and 50% for densification. Fourier transform infrared (FTIR) spectroscopic and thermal properties of heat-treated samples wer...

| description | In the present study, heat-treatment was applied to brutian pine (Pinus brutia Ten.) wood samples at 120, 160 and 200oC, and then the samples were pressed in the ratio of 25% and 50% for densification. Fourier transform infrared (FTIR) spectroscopic and thermal properties of heat-treated samples were investigated. The physical and mechanical properties of the heat-treated and densified samples were evaluated. FTIR spectroscopic findings showed that there was no remarkable change in the crystallinity index of the samples due to heat-treatment. It was observed that the heat-treated samples had lower material loss than the control samples at the main decomposition phase in the thermogravimetric analysis (TGA) and differential thermogravimetry (DTG) curves. However, according to the TGA and DTG findings, it was determined that a significant level of holocellulose loss occurred in the samples with the increase of the temperature applied in the heat-treatment. In the results obtained, it has been seen that it can be recommended to apply heat treatment before densification, if the thermo-mechanically densified brutian pine samples are considered to be used in environments where they can come into contact with water. In addition, heat-treatment and densification methods can be recommended to be used together for increase the usability of wood materials in load-bearing applications and outdoor (siding, park and garden furniture, etc.) or indoor (paneling, parquet, sauna, furniture elements, etc.) applications, as well as partially fire-resistant structures. |
