Abstract

The aim of this study is to investigate the effects of impregnation chemicals on the weight loss during combustion of Laminated Veneer Lumber (LVL) obtained from combination of Oriental beech + Lombardy poplar and European oak + Lombardy poplar woods, impregnated with Borax (Bx), Boric acid (Ba), Bx+Ba (wt:wt 50:50%), Imersol-aqua and Timbercare-aqua according to ASTM D 1413. The LVL samples were prepared in the form of five layers, 3 mm thickness from the beech, oak and poplar veneers bonded with Desmodur-VTKA and Poly(vinyl acetate) adhesives, according to TS EN 386. The weight loss during combustion of the LVL test samples was determined according to ASTM E 160. Consequently, the weight loss percentage was the highest in beech-poplar combination processed with Imersol-aqua and DVTKA and the lowest in oak-poplar combination, Ba+Bx and PVAc adhesive. In the interaction of the wood materials, impregnation chemicals and adhesive types, it was the highest in beech-poplar combination + Timbarecare-aqua + DVTKA and the lowest in beech-poplar combination + (Ba+Bx) + PVAc. As a result, it can be said that the type of impregnation material has a first degree efficacy and wood material have second degree efficacy on the weight loss. Thus, the weight loss was high in beech-poplar combination impregnated with Ta but low in the same wood material impregnated with Ba+Bx. Accordingly, for places which has fire risk, usage of LVL wood material impregnated with boron compounds would be advantageous.

 

Key Words: Combustion, Impregnation Solutions, Weight Loss, Laminated Veneer.
