Thermal conductivity refers to the temperature difference between the two sides of a material with a thickness of 1 m under a stable heat transfer condition of 1 degree (K/°C), and the heat transferred through an area of 1 square meter in 1 hour, in watts/meter.degree (W/(m·K), K can be replaced by ℃).
The thermal conductivity of ceramic fiber products is used to characterize the size of their thermal conductivity.
There are many factors affecting the thermal conductivity of ceramic fibers, which mainly depend on the structure, bulk density, temperature, pressure, ambient atmosphere and humidity of ceramic fiber products.
The bulk density of the ceramic fiber blanket and the ceramic fiber module is very different. The bulk density of the blanket is 96Kg/m³ and 128Kg/m³, and the bulk density of the ceramic fiber module is 220Kg/m³. Both are lightweight refractory fiber products with low thermal conductivity and good thermal insulation effect. From the technical index query of the ceramic fiber module and the blanket, it can be seen that the thermal conductivity of the two is not much different.
However, in the thermal calculation of industrial furnace applications, the thermal conductivity of the ceramic fiber module is calculated as 1.3 times the thermal conductivity of the blanket. This is because when the ceramic fiber modules are used as industrial furnace linings, they are fixed on the metal furnace shell with the help of high-temperature metal anchors. The calculation of thermal conductivity at different temperatures is based on the data of domestic application of ceramic fiber products for many years. Formula and coefficient between ceramic fiber module and blanket thermal conductivity.
