Polycrystalline mullite fiberboard can also be called polycrystalline alumina fiberboard. It is formed by wet vacuum filtration and pressure, and is made of loose cotton plus organic and inorganic binders.
The product has a hard texture and excellent strength, is resistant to erosion, and is easy to process and cut.
Its raw material refractory fiber has stable chemical properties, so it is light in weight and has good thermal insulation effect. It is a multi-purpose product that can be used for the hot surface of the furnace lining to resist flames and high-temperature airflow direct impact.
Advantages:
High temperature stability, low thermal conductivity, thermal shock resistance, erosion resistance, easy processing and cutting performance, precise thickness and size, good resistance to flames and airflow erosion
Application:
Lining or backing of various high-temperature furnaces, high-temperature fire baffles and seals, fireproof insulation
Technical parameters:
Temperature: 1600-1800℃
Chemical composition:
Al2O3: 68-85%
Al2O3+ SiO2: 99.5-99.8%
Fe2O3
