Abstract

This study was carried out to determine the impact of bleaching and varnishing on the glow-combustion temperature of wood material. For this purpose, specimens prepared according to ASTM D 358 from European Oak, Oriental beech and Scotch pine wood are bleached with a solution of 18% sodium hydroxide (NaOH), hydrogen peroxide (H2O2), calcium hydroxide (CaOH2), sodium silicate (NaSiO3), acetic acid (CH3COOH), sodium disulfide (Na2S2O5), oxalic acid (H2C2O4) and potassium permanganate (KMnO4). The bleached specimens are varnished with synthetic (Sn) waterborne (Sb), polyurethane (Pu) and acrylic (Av) in accordance with ASTM D 3023. The glow state combustion properties were determined in accordance with ASTM E 160-50. Consequently, the glow state combustion temperature; wood species, bleaching materials and varnish types of open interaction European oak+R-3+Synthetic varnish according to the highest, the lowest oriental beech+R-1+su bazli varnish at were obtained. Accordingly, the desired fireproof in the wood product applications made of European oak wood, bleached with R-3 (NaSiO3+H2O2) and coated with a synthetic varnish, use may be recommended.
