Aluminum silicate fiber felt is a kind of refractory thermal insulation material with low thermal conductivity. With the wide application, more and more people do not know how to choose when using it, and there are many similar types. The editor compares the spinneret blanket and the aluminum silicate fiber blanket to see what are the differences between the two?
Aluminum silicate fiber felt is a kind of refractory thermal insulation material with low thermal conductivity. With the wide application, more and more people do not know how to choose when using it, and there are many similar types. The editor compares the spinneret blanket and the aluminum silicate fiber blanket to see what are the differences between the two?
1. The fiber length of the aluminum silicate fiber blanket is longer. The throwing fiber is generally 150-250 mm, and the spinning fiber is generally 100-200 mm.
2. Thermal conductivity: Spinneret blankets are better than silk blankets because of their finer fibers.
3. Vertical lamination application of large blankets such as waste heat boilers: aluminum silicate fiber blankets have good tensile strength and durability due to their thick and long fibers, which are better than spinneret blankets.
4. The tensile and bending strength of aluminum silicate fiber felt is better than that of spinneret felt because its fibers are thicker.
5. The fiber diameter of the aluminum silicate fiber blanket is thicker, the throwing fiber is generally 3-5m, and the spinning fiber is generally 2-3m.
6. Application of making ceramic fiber blocks: The fibers of aluminum silicate fiber blanket are thick and long, which is better than silk carpet. During the folding process of block making, the spinneret is easy to break and tear, while the aluminum silicate fiber blanket can be folded very tightly and is not easy to damage, so the quality of the block will directly affect the quality of the lining.
The above is the difference between aluminum silicate fiber blanket and spinneret blanket. Each has its own advantages, and mind as a reference when purchasing. Aluminum silicate fiber blanket is mainly used in furnace lining, boiler, sound absorption and insulation and other components.
