Ceramic fiberboard is a widely acclaimed and widely used refractory insulation material. Its advantages are numerous, such as light bulk density, good thermal stability, high temperature resistance, low thermal conductivity, elasticity, sound insulation, mechanical vibration resistance, electrical insulation, good chemical stability and so on.

Ceramic fiber board is made of ceramic fiber loose cotton as raw material, adding adhesive, etc., and is made by wet vacuum forming process. The process is slightly more complicated, so the price is also slightly more expensive. The finished ceramic fiber board is mainly used in fire and heat insulation projects.

Ceramic fiberboard has been widely used in various industrial fields, including metallurgy, electric power, machinery, chemical industry, etc. In the industry, it is mainly used as a protection project for high-temperature equipment, and is also used in high-temperature sealing, catalyst carrier, muffler, filtration, composite material reinforcement, such as baffles of high-temperature ceramic kilns, baffles of furnace doors, etc.

Advantage:
Compared with ceramic fiber blankets, ceramic fiberboards are hard refractory materials with high density, high strength, and resistance to airflow erosion. The surface fibers are not easy to peel off, and can directly contact the flame. Fiber blankets such as flame baffles and kiln temperature zones are not competent. part.

Compared with refractory bricks, the outstanding feature of ceramic fiberboard is that it is light in weight, and its weight is only 1/4 of that of refractory bricks, which can effectively relieve the load-bearing of the furnace body; in addition, traditional refractory bricks have poor resistance to rapid cooling and rapid heating, and are easy to crack. This phenomenon does not exist for ceramic fiberboards with excellent thermal stability.

Shortcoming:
Ceramic fiberboard is a rigid refractory insulation board, which is limited in applications such as curved kiln walls or special-shaped furnaces. Furthermore, the price of ceramic fiberboard is slightly higher than that of fiber blankets and other products.
