Good formability was obtained at initial mat densities ranging 200-300 kg/m^3 and at carbonizing tenperatures ranging 400-500℃. Thermal conductivity of carbonized wood shaving mats was measured as a function of initial mat density and carbonizing temperature, and it was found that the minimun thermal conductivity was 25% less than that of wood shaving mats before carbonizing. To investigate the mechanisms behind this better insulation, apparent thermal connductivity of coarse pores which includs the effects of convective and radiative heat transfer was calculated by the use of a mix law of thermal conduction. On the other hand, relationships between carbonization temperature and adsorption ability to formaldehyde and ammonia were examined and then the mechanisms behind the adsorption ability were discussed from surface chemical characteristics and pore sizes.

初始板坯密度为2 0 0~30 0 kg/mm2，碳化温度为4 0 0~5 0 0℃时，可获得良好的成形性。测定了炭化刨花板的导热系数随初始密度和炭化温度的变化关系，发现炭化前刨花板的最小导热系数比炭化前降低了25%。为了探讨隔热效果好的机理，利用混合导热定律计算了考虑对流换热和辐射换热影响的粗孔的表观导热系数。另一方面，考察了炭化温度与其对甲醛和氨的吸附能力之间的关系，并从表面化学性质和孔径大小等方面探讨了吸附能力背后的机理。
