The bulk density of ceramic fiber blanket will affect the performance and use effect of the product to a certain extent, because its bulk density refers to the ratio of the weight of fire-resistant insulation cotton to the overall material. The bulk density is an index to determine whether the selection of furnace lining is reasonable, and it is an important factor affecting the thermal conductivity. Therefore, when purchasing this product, we must pay attention to this aspect. Then, what factors are related to its bulk density?
There is heat transfer between any object. Ceramic fiber blanket is a new environmental protection material for thermal insulation, and it also needs to achieve the thermal insulation effect through heat transfer. Many people wonder whether the higher the bulk density of the material, the better the performance effect. In fact, it is not true. The thermal conductivity of fiber blanket decreases with the increase of bulk density, but if the decline fluctuation decreases gradually, Then when the density exceeds a certain scale, the thermal conductivity will increase. At different temperatures, small thermal conductivity corresponds to small bulk density, and the bulk density corresponding to small thermal conductivity will increase with the increase of temperature.
Therefore, we should pay more attention to the problem of bulk density when purchasing ceramic fiber blanket or installing and using it, so as to avoid other external factors affecting its bulk density and affecting its use effect.
