The thermal conductivity of the material in the aluminum silicate fiberboard will directly affect the actual application status and has a certain relationship with the density of the selected material. The specific influencing factors are as follows:
1. First of all, the most important thing is that temperature has a direct effect on the thermal conductivity of various aluminum silicate fiberboard materials. If the temperature rises, the thermal conductivity of the material will also increase.
2. The ceramic fiber board has a porous structure, which can perform simple moisture absorption, and will increase its thermal conductivity after moisture absorption.
3. The bulk density of the aluminum silicate fiberboard will affect the porosity of the material. Generally, increasing the porosity or reducing the bulk density will cause the thermal conductivity to decrease.
4. In the thermal insulation materials used in the aluminum silicate fiberboard, most of the heat is transferred from the gas in the pores. Therefore, it can be considered that the thermal conductivity of this thermal insulation material is basically the same as the thermal conductivity of the gas.
Many factors affect the thermal conductivity of aluminum silicate fiberboard, but as long as you understand what these factors will affect the product, it is the right step to avoid reducing the product’s thermal insulation performance.
