[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.
