product details

• DESCRIPTION

Ceramic fiber board is made from made from the main raw material of aluminium silicate (alumina + silica) by melting at a temperature above 2000℃. Blowing into fibers by high-speed gas flow. Then add the inorganic binders. The board is formed through a wet vacuum forming process and high-temperature pressing. The common high-density grades are mostly above 300–400 kg/m³, and some can reach 600 kg/m³.


• PROPERTIES

Ø High temperature resistance and strong thermal stability: The long-term service temperature can reach 1000–1400℃ (depending on the material grade), resistant to thermal shock, and not prone to cracking when subjected to rapid heating and cooling; 

Ø Low thermal conductivity + low heat capacity: With a heat capacity only 1/10 that of lightweight refractory bricks, resulting in significant energy-saving effects; 

Ø Good chemical stability: Resistant to acids and alkalis, resistant to wind erosion, and not easily penetrated by molten non-ferrous metals;

Ø Lightweight, sound-absorbing, and convenient for construction.


• APPLICATION

Ø Industrial kilns: Inner lining / backing insulation for steel rolling heating furnaces, ceramic shuttle kilns, and petrochemical cracking furnaces;

Ø High-temperature equipment: Insulation layers for heat treatment furnaces, glass furnaces, and aluminum electrolytic cells;

Ø High-temperature seals / gaskets, expansion joint fillers, fireproof isolation barriers, etc.
