Ronghua ceramic fibre sheet is a high-temperature insulation product made from high-performance ceramic fibers. It is made through advanced pressing production. Ceramic fiber insulation boards have numerous advantages, such as insulation, heat resistance, and good mechanical strength. Depending on the composition, Ronghua offers standard ceramic fiber boards, high-purity ceramic fiber boards, alumina ceramic fiber boards, zirconia ceramic fiber boards, and other products.
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.
Industrial Chemicals
In the industrial chemicals industry, refractory insulation boards can withstand high temperatures, thermal shock, and chemical corrosion. They are widely used in the steel smelting industry, ceramic industry, glass industry, power industry, chemical industry, defense industry, semiconductor industry, and more. They are commonly used in furnaces, gaskets, linings, seals, converters, parts, and so on.
Construction and Transportation
In the construction and transportation industries, ceramic fiber boards have excellent thermal insulation and fire resistance properties. They are used in the construction industry, automotive industry, maritime industry, aviation industry, and more. They are used in building walls, roofs, fireplaces, engine heat shields, exhaust pipe insulation sleeves, turbocharger heat shields, cabin insulation materials, and so on.
Firefighting
In the firefighting industry, ceramic fiber thermal insulation boards can effectively provide fire insulation. They are used in the construction of fire protection equipment, such as fire doors, firewalls, firefighting clothing, firefighting blankets, firefighting vehicle heat shields, fireproof rolling shutter doors, and so on.
