1. Product introduction
Polycrystalline mullite fiberboard can also be called polycrystalline alumina fiberboard, which belongs to wet vacuum suction and pressure forming, and is made of loose cotton and organic and inorganic binders. The product has a hard texture and excellent strength, anti-scouring, easy processing and cutting. The 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 applied to the hot surface of the furnace lining to resist the direct impact of flame and high-temperature airflow.
