Description of High Density Fireproof Insulation Ceramic Fiber Blanket Thermal Insulation Blanket
Ceramic fiber blanket is a kind of refractory heat insulation material that is widely used for high temperature heat insulation. Such as Industrial furnace , heating devices, high temperature pipe wall lining. It’s environment-friendly material as a replace of asbestos. Also it is with the features of excellent thermal insulation, insulation, fireproof and sound absorption.
The service temperature of a Ceramic fiber blanket can be 1000℃,
1260℃, 1360℃, or 1430℃. It includes common type, standard type,
high purity type, high alumina type, and zirconium-containing type.
Application of Ceramic Fiber Blanket
Industrial building materials kiln, heating device,
high-temperature pipe lining; chemical industry high-temperature
reaction equipment and heating equipment wall lining; thermal
insulation for electric boilers, gas turbines, and nuclear power
plants; fire insulation layer for high-rise buildings; furnace
door, roof heat insulation; high-temperature filter material and so
on.
