Abstract

In order to restrain the combustion of the sliced bamboo plywood and its products, which were used as decorating materials, significantly the materials above should be treated with fire retardant to increase their safety security. The effect of temperature, time, and dipping concentration on the chemical loading of sliced bamboo veneer were tested by thermostatic bath utilizing complex fire retardants at constant pressure. Combustible properties and mechanical properties of the fire-retardant sliced bamboo plywood were also determined using oxygen index and bonding strength tests. Results showed that the best impregnation conditions were 60 ℃ for 8.0 h at an impregnation concentration of 300.0 gL－1. Combustible properties of heat release rate, total heat release quality, and smoke release rate, decreased as chemical loading increased; however, residual material quantity and light time increased. The oxygen index of the treated plywood increased; when the chemical loading was 8%, the oxygen index reached the B1 fire-retardant grade as per JISD 1322－1977. Although bonding strength decreased with an increase in chemical loading, the national standard for Class Ⅱ plywood was maintained. So, it was feasible that Sliced Bamboo plywood could be manufactured by the impregnation process under atmospheric pressure. ［Ch, 6 fig. 2 tab. 12 ref.］
