One of the most popular insulation materials used these days include Ceramic fiber blanket is a lightweight needled blanket that is extensively used in a range of thermal insulation applications. The material is preferred due to its superior insulation performance and low thermal conductivity. It is manufactured using double needling and spinning techniques.
Made of silica, alumina and zirconia, it is a good insulator with low shrinkage. The material does not produce any fumes, as it is organic in nature. The material is often used in environments that expose it to chemical reactions, as it remains unaffected.
Ceramic fiber blanket retains its thermal properties even after getting wet by water, steam or other liquids. The material is used for wrapping fire protection applications and structural steel. You can get it in a variety of chemical compositions, thicknesses, and density combinations.
Here are some of the benefits and application area listed:
Low thermal conductivity: The ceramic fiber blanket has low thermal conductivity, so it can be used in the sidewall of extremely high temperature furnaces. It prevents heat loss and it has low heat storage as well as low thermal capacity.
Lightweight: The product is light in weight, which makes construction easy. The material has no expansion and it can be cut according to the size requirements at the site. The damaged or broken ceramic fiber blanket can be repaired or removed without removing the entire blanket. This leads to huge saving.
Low bulk density: It has lower bulk density as compared to the insulation brick. Being thinner than the regular refractory material, the ceramic fiber blanket reduces the volume of the masonry and the thickness of the furnace; thus, helping you save on construction materials.
Being soft and flexible ceramic fiber blanket remains protected from the mechanical shocks and rapid temperature variations. The fiber is available in different grades, which are used differently
