Ceramic fiber blanket is produced from high strength ceramic fibers and is double needled to provide exceptional handing strength. We can provide 5 grades of ceramic fiber blanket, including refractory temperature 1260C standard,1260C high pure,1360C high Aluminium,1360C Zir-Alu and 1430C Zirconium ceramic fiber blanket,have been exported to more than 30 countries.
Characteristic
low thermal conductivity , low thermal capacity,and excellent thermal insulation property.
High temperature stability ,resistance to thermal shock
Good tensile strength
Excellent sound absorption, fire protection and chemical corrosion resistance.
Application
Mainly serve as the ceramic fiber lining for industrial furnaces, heating equipment and high- temperature pipelines,such as
Metallurgy Industry: heating furnaces,heat treatment furnaces and ladle insulated cover
Mechanism industry: thermal insulation material for electric power boilers, gas turbine engine and nuclear power plant
Petrochemical industry: the lining of high-temperature reaction equipment and heating equipment in chemical fields,like converting furnaces, constant/reduced pressure furnaces, cracking furnaces, flue lining.
Ceramics and electroceramics: roller kilns,tunnel kilns ,shuttle kilns and other kinds of furnaces.
Other fields: thermal insulation for top cover of furnace doors.Fire protection material in high buildings. High temperature filter material.The lining of hot-air pipes,high temperature equipment and high-temperature furnaces.
