Refractory fiber, as the name implies, refers to fiber products with fire resistance. This product not only has the characteristics of softness, high strength and processability of ordinary fibers, but also has the properties of high temperature resistance, corrosion resistance and oxidation resistance of refractory materials.
If you want to know whether the aluminum silicate fiber blanket is a refractory fiber, first understand the basic characteristics of the refractory fiber:
1. High temperature resistance, operating temperature 1000-2500 ℃; The service temperature of aluminum silicate fiber blanket is 850-1260 ℃;
2. Low thermal conductivity, only 1/5-1/10 of refractory bricks at 100 ℃; The thermal conductivity of aluminum silicate fiber blanket at 400 ℃ is only 0.086w/m.k
3. Chemical stability, oxidation resistance and corrosion resistance; In addition to strong acid and alkali, aluminum silicate fiber blanket is almost free from chemical corrosion.
4. Good thermal shock resistance; The aluminum silicate fiber blanket has high porosity and can effectively absorb the thermal shock caused by high temperature.
5. Low heat capacity; Aluminum silicate fiber blanket has a low heat storage capacity and can hardly absorb heat.
6. Soft, strong processability; Aluminum silicate fiber blanket can be processed into ceramic fiber board, ceramic fiber castable, ceramic fiber coating, refractory cloth, high-temperature packing and other derivative products as required.
It can be seen that aluminum silicate fiber blanket is one of the conventional products of refractory fiber. In addition, there are mullite fiber with high temperature resistance, asbestos and glass fiber with low temperature resistance.
