Product description of ceramic fiber blanket
Ceramic fiber blanket, also known as aluminum silicate fiber blanket, because one of its main components is alumina, and alumina is the main component of porcelain, so it is called ceramic fiber blanket. Ceramic fiber blanket is mainly divided into ceramic fiber blowing blanket and ceramic fiber spinning blanket. Ceramic fiber spinning blanket is better than ceramic fiber blowing blanket in thermal insulation performance because of the long fiber wire and small thermal conductivity. Most insulation pipe construction uses ceramic fiber swing silk blanket.
Features of ceramic fiber blanket
Ceramic fiber blanket has low thermal conductivity, low heat capacity, excellent chemical stability, excellent thermal stability, and shock resistance, excellent tensile strength, excellent sound absorption, insulation refractory material in the excellent material.
