(2009) Fire resistance performance of particleboard made from kenaf core treated with fire retardants. [Proceedings Paper]

The fire resistance performance of medium density particleboard made from kenaf Hibiscus cannabinus core particles treated with three different commercial fire retardants was studied using 10 concentration of fire retardants. The fire resistance test was evaluated using insulation and integrity evaluations. Insulation is the ability of the board to prevent the temperature of the unexposed face to increase excessively whereas integrity is the ability for the board to prevent collapse and sustained flaming on the unexposed face. The study showed that BPa mixture of 27-33 boric acid 67-73 guanylurea phosphate and 0.04.2 phosphoric acid was excellent in increasing the insulation and the integrity of the sample compared with monoammonium phosphate MAP and diammonium phosphate DAP. However MAP performed better in both evaluations compared with DAP. BP was able to provide better protection against fire because of the existence of boron compounds in its formulation. Char was found to form faster on the boards treated with MAP and DAP compared with BP. The phosphorus in MAP and DAP enhanced the formation of char on the surfaces of the samples hence reducing the flame spread.

Abstract

The fire resistance performance of medium density particleboard made from kenaf Hibiscus cannabinus core particles treated with three different commercial fire retardants was studied using 10 concentration of fire retardants. The fire resistance test was evaluated using insulation and integrity evaluations. Insulation is the ability of the board to prevent the temperature of the unexposed face to increase excessively whereas integrity is the ability for the board to prevent collapse and sustained flaming on the unexposed face. The study showed that BPa mixture of 27-33 boric acid 67-73 guanylurea phosphate and 0.04.2 phosphoric acid was excellent in increasing the insulation and the integrity of the sample compared with monoammonium phosphate MAP and diammonium phosphate DAP. However MAP performed better in both evaluations compared with DAP. BP was able to provide better protection against fire because of the existence of boron compounds in its formulation. Char was found to form faster on the boards treated with MAP and DAP compared with BP. The phosphorus in MAP and DAP enhanced the formation of char on the surfaces of the samples hence reducing the flame spread.
