THE EFFECTS OF IMPREGNATION CHEMICALS ON COMBUSTION PROPERTIES OF LAMINATED WOOD MATERIAL

Abstract

In this study, the effects of impregnation materials, sodium perborate, sodium tetraborate, Imersol-WR 2000, and Tanalith-CBC, on combustion properties of three-ply laminated wood material produced from Uludagˇ fir (Abies bornmülleriana Mattf ) were investigated. The wood samples were impregnated with chemicals via a dipping method. Prepared materials have been bonded with Desmodur-VTKA adhesive and tested according to the procedure of ASTM-E 69 standards. As a result, the highest mass reduction in massive wood samples impregnated with Tanalith-CBC were determined. CO and CO₂ ratios were obtained in massive control samples, which were unprocessed. Temperature variation in laminated samples impregnated with Tanalith-CBC, O₂ ratio in massive wood samples impregnated with sodium tetraborate, and ash ratio in laminated samples impregnated with sodium perborate were obtained.
