Thermal conductivity analysis of ceramic fiber blanket

Thermal conductivity analysis of ceramic fiber blanket: When the fiber blanket is at a high temperature of 1000 ° C, its thermal conductivity is only 15% of that of refractory clay brick. Why is it so low?

This can be analyzed from the following aspects.
   1 temperature. The thermal conductivity will correspond to the bulk density at different temperatures. Generally speaking, this bulk density will increase with increasing temperature.

   2 weight. As the bulk density increases, the thermal conductivity of the aluminum silicate fiber decreases, but the magnitude of this decrease tends to decrease. The article draws on zibotengda.com related information. When the bulk density increases beyond a certain range, the thermal conductivity will not increase but will increase.

     Shandong Zouyu International Trade Co., Ltd. is mainly engaged in ceramic fiber blanket, aluminum silicate fiber cotton, aluminum silicate fiber felt, aluminum silicate fiber board, aluminum silicate fiber paper, aluminum silicate fiber module, aluminum silicate fiber composite block and so on.
