Buy good quality low price high temperature resistant Ceramic Fiber Blanket for various applications at Wedge India. Ceramic fiber blanket is a highly efficient insulation material made from high-purity ceramic fibers. These fibers are spun and needled into a blanket form, providing excellent thermal insulation properties. Ceramic fiber blankets are widely used in industries requiring high-temperature resistance, thermal shock resistance, and low thermal conductivity.
Key Features and Properties of Ceramic Fiber Blanket
1. High Temperature Resistance: Ceramic fiber blankets can withstand extremely high temperatures, typically ranging from 1,260°C (2,300°F) to 1,430°C (2,606°F), depending on the grade and composition. This makes them suitable for use in high-temperature environments.
2. Low Thermal Conductivity: The material has very low thermal conductivity, making it an effective thermal insulator. This property helps reduce heat loss in industrial processes, improving energy efficiency.
3. Excellent Thermal Shock Resistance: Ceramic fiber blankets can endure rapid temperature changes without cracking or breaking, which is critical in applications where temperatures fluctuate frequently.
4. Lightweight and Flexible: Despite their high-temperature resistance, ceramic fiber blankets are lightweight and flexible, allowing for easy handling, cutting, and installation. They can conform to complex shapes, making them versatile in a wide range of applications.
5. High Tensile Strength: The blanket is needled to provide high tensile strength, which ensures durability and resistance to tearing or mechanical damage during installation or operation.
6. Sound Absorption: In addition to thermal insulation, ceramic fiber blankets also offer sound absorption properties, making them useful in applications where noise reduction is important.
7. Chemical Stability: Ceramic fiber blankets are chemically stable and resistant to most chemicals, including acids and alkalis. They are also non-reactive with other refractory materials and molten metals.
8. Non-Combustible and Fire Resistant: The blanket is non-combustible and provides excellent fire resistance, making it an ideal material for fire protection and safety in high-temperature environments.
Common Applications of Ceramic Fiber Blanket
1. Furnace and Kiln Insulation: Ceramic fiber blankets are used to line the interiors of industrial furnaces and kilns to reduce heat loss and improve energy efficiency. They can also be used as a backup insulation layer behind refractory bricks.
2. Pipe and Duct Insulation: The blanket is wrapped around high-temperature pipes and ducts to provide thermal insulation and prevent heat loss in processes involving hot gases or liquids.
3. Heat Shields and Linings: Used as heat shields in various industrial applications, ceramic fiber blankets protect equipment and structures from excessive heat. They are also used to line heat-treating furnaces, boilers, and other high-temperature equipment.
4. Fire Protection: Due to their excellent fire resistance, ceramic fiber blankets are used in fire protection systems, such as fire curtains, fireproof doors, and barriers. They help prevent the spread of fire and protect critical structures from heat damage.
5. Automotive and Aerospace Applications: In the automotive and aerospace industries, ceramic fiber blankets are used to insulate exhaust systems, turbochargers, and other components exposed to high temperatures. They help reduce heat transfer and protect surrounding materials.
6. Expansion Joint Fillers: Ceramic fiber blankets are often used as fillers in expansion joints in high-temperature environments, accommodating thermal expansion and contraction without damage.
7. Soundproofing: In addition to thermal insulation, ceramic fiber blankets are used in applications where sound absorption is needed, such as in engine compartments or industrial equipment enclosures.
