摘要

本研究以田口試驗計畫法針對木質裝修材料在不同影響著火性試驗變數下，如板材、板厚、阻燃塗料塗佈量和阻燃塗料配比，使用L9(34)之直交表進行實驗配置，並仿照ASTM E1623試驗規範進行熱輻射著火性試驗。試驗結果分析，影響木質材料受25 kW/平方公尺熱輻射其著火性因素之排序，最大者為阻燃塗料配比，貢獻度為48.72%。根據田口試驗結果之最佳因子水準組合，針對阻燃塗料塗佈量因子進行深入試驗研究，可得木質材料阻燃處理之最佳阻燃塗料塗佈量為3919/平方公尺。以田口試驗法探討因素與水準數所建立之直交表，簡化多變數繁雜之試驗，較全因子實驗法試驗次數少且各試驗之再現性高。

This research used Taguchi method to analyze the ignitability of wood-based material under different variables, such as the material, the thickness, the degree of coating, and the formulation of coating. Taguchi method adopts the orthogonal array of L9(34) for experiments. The testing methodology adopts in this research simulated that specified in ASTM E1623. From experiment results, it was found that, under 25 kW/m^2 thermal radiation, the ranking most significant influence on the ignitability, is formulation of coating, which contributes 48.72 % of heating retarding performance. By regression analysis of Taguchi method, it's concluded that the optimal amount of coating for wood-based materials tested is 391 g/m^2. It is also found from this research that the Taguchi method provides a more efficient approach, compound with the traditional full-factor experiment method, in number of experiments required.
