Key Features of High Temperature Ceramic Fiber Board
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.
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, it can effectively reduce building weight loads and improve insulation performance.
The aluminum silicate fiber 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.
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.
Environmentally friendly, the high temperature fiber board is a tasteless, non-toxic, eco-friendly material composed of natural ingredients without harmful substances. It does not emit harmful gases at high temperatures during use and can be recycled for reuse
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.
