Description of Ceramic Fiber Module
Ceramic fiber modules are manufactured through a process of needle-felting ceramic fiber insulation blanket followed by further processing. This process results in ceramic fiber modules with uniform density and no gaps. These modules are easy to install and have strong mechanical resistance. Additionally, their excellent thermal insulation properties can bring high energy efficiency to high-temperature industries. Kerui Refractory can customize exclusive products for partners according to their construction conditions and application fields.
Key Features of Kerui Ceramic Fibre Module
- High fire resistance: Ceramic fiber modules can withstand extreme temperatures ranging from 1260°C to 1460°C (2300°F to 2660°F) without melting or burning. This makes them an ideal choice for fire protection applications in high-temperature environments.
- Low thermal conductivity: These modules have a low thermal conductivity. This means they effectively resist heat transfer.
- Strong resistance to thermal shock: This product is resistant to thermal shock due to their low thermal expansion coefficient. This means they can withstand rapid temperature fluctuations without losing their structural integrity.
- Strong chemical stability: Ceramic fiber modules are chemically stable and resistant to a wide range of chemicals, including acids, alkalis, and solvents. This makes them suitable for use in harsh environments with aggressive chemicals.
- High abrasion resistance: The interlocking crystal structure of ceramic fibers provides them with excellent abrasion resistance. This means they can withstand wear and tear from abrasive materials. This makes them suitable for use in applications where they may be subjected to friction or mechanical abrasion.
- Easy installation: Ceramic fiber modules are lightweight and flexible. This makes them easy to handle and install. They can be cut to size and shaped to fit various applications.
