Product introduction of ceramic fiber blanket
The ceramic fiber blanket is formed by a special aluminum silicate ceramic fiber filament through a special double-sided needle punching process. After the double-sided needle is processed, the interweaving degree, delamination resistance, tensile strength and surface flatness of the fiber are greatly improved. The fiber blanket does not contain any organic binder, which ensures that the ceramic fiber blanket has good manufacturability and stability under high and low temperature working conditions.
Features of ceramic fiber blanket
The ceramic fiber blanket has low thermal conductivity, low heat capacity, good chemical stability, good thermal stability, impact resistance, good tensile strength, good sound absorption performance, and is an excellent material in the refractory insulation materials.
Applications of ceramic fiber blanket
Ceramic fiber blanket is used for industrial kilns, wall lining and back lining of thermal insulation, thermal insulation of high-temperature equipment, thermal insulation of high-temperature pipelines, thermal insulation and fireproof of electrical components, and high-temperature joints.
