【摘要】：以防护热板法测量热导率,分析了测试温度(≤500℃)、密度对硅酸铝纤维板热导率的影响,建立了硅酸铝纤维板热导率的拟合方程,并通过实际测量对拟合方程进行验证。结果表明:硅酸铝纤维板的热导率与测试温度、密度具有显著的线性关系。实测结果与拟合方程的计算结果相吻合,≤300℃时的偏差在±3%以内,500℃时的偏差在±5%以内,可见,拟合方程准确可靠,可作为硅酸铝纤维板热导率确定的一种参考方法。
[Abstract]:The thermal conductivity was measured by the protective thermal plate method. The effect of the test temperature (less than 500) and the density on the thermal conductivity of the aluminum silicate fiberboard was analyzed. The fitting equation of the thermal conductivity of the aluminum silicate fiberboard was established. The fitting equation was verified by the actual measurement. The results show that the thermal conductivity of the aluminum silicate fiberboard has a significant line with the test temperature and density. The measured results are in agreement with the calculated results of the fitting equation. The deviations at less than 300 degrees are within + 3%, and the deviation at 500 is less than 5%. The fitting equation is accurate and reliable, which can be used as a reference method for determining the thermal conductivity of aluminum silicate fiberboard.
