Key Features of High Temperature Ceramic Fiber Board
High-temperature Resistance
The melting point of high-temperature resistant ceramic fiber board insulation can reach up to 1700 degrees Celsius. It has a strong ability to withstand high temperatures, exhibiting thermal stability and resistance to thermal shock.
Absorb Sound Waves
The various characteristics of the ceramic fiber insulation board, such as its porous structure, low density, lightweight, and fiber wrapping structure, allow it to absorb, reflect, and reduce the intensity of sound waves, making it widely used in industrial sound insulation applications.
Low Thermal Conductivity
The thermal conductivity coefficient of the fireproof fiber board ranges from 0.09 to 0.22 W/(m·K) between 400-1000ºC. It is lower than dense refractory bricks. This feature effectively reduces heat transfer and achieves thermal insulation. Additionally, with a density between 260-320 kg/m³.
Strong Processability
The ceramic fiber insulation board is highly processable due to its strong flexibility. It can be altered in size and shape through cutting, shaping, bonding, sewing, and other processing methods to meet the dimensional requirements of different application scenarios.
Strong Corrosion Resistance
Ronghua ceramic fiber insulation board exhibits strong chemical corrosion resistance, with its composition having good chemical stability. Its porous structure and high-temperature stability enable it to withstand corrosion in acidic, alkaline, and neutral chemical environments.
Applications of Ronghua Ceramic Fibre Board
