Aluminum silicate fiber blanket is a kind of heat-resistant thermal insulation material. Most of the time, we can only know what its function is for, but rarely understand the characteristics of the product and the prone problems of the product. For example, why does the thermal conductivity decrease when we use fiber blanket at high temperature? Well, let’s give you a brief introduction.
When the aluminum silicate fiber blanket is at a high temperature of 1000 ℃, its thermal conductivity is only 15% of that of fireclay brick. It will have such a low thermal conductivity, which can be analyzed from the following aspects:
1. Temperature. At different temperatures, the thermal conductivity will correspond to the bulk density. Generally speaking, this bulk density will increase with the increase of temperature.
2. Bulk density. With the increase of bulk density, the thermal conductivity of aluminum silicate fiber will decrease, but the decrease range is decreasing. When the bulk density increases beyond a certain range, the heat conductivity will not decline but rise.
The above is the reason why the thermal conductivity of aluminum silicate fiber blanket decreases at high temperature, which is mainly due to the problems of temperature and product bulk density. Through the introduction in the above article, we know that the temperature is directly proportional to the unit weight of the product. When the unit weight exceeds the range, the thermal conductivity of the product will rise accordingly, and vice versa.
