High-quality Production of Kerui Ceramic Fiber Insulation Blanket
Ceramic blanket is an insulation material made of ceramic fibers through needling and other processes. The needling process interlaces the ceramic fibers to form a strong network structure. It can improve the performance of the insulation blanket, such as strength, wear resistance, thermal insulation, and so on.
Its main components are kaolin, alumina, and silica. These raw materials give the finished ceramic fiber blanket excellent thermal stability and high-temperature resistance. In addition to standard products, we support custom ceramic fiber blankets to meet the special needs of customers in the insulation industry. We also provide other insulation brick and insulation products. Consult us.
Typical Applications of Kerui Ceramic Fibre Blankets
- Industrial kiln wall lining;
- Backing materials;
- High-temperature pipeline insulation;
- Kiln masonry expansion seams, furnace doors, and top cover heat sealing;
- Module, folding block processing material;
- Fire parcel.
Advantages of Kerui Ceramic Fiber Blankets
1. High Temperature Resistance
Ceramic fiber blankets can be used at temperatures up to 1430ºC. They can withstand high temperature working environments and maintain normal performance, extending the life of the kiln.
2. Good Thermal Stability
Ceramic fiber blankets will not deform structurally under rapid temperature changes. They have low permanent linear change. They provides protection for the kiln under thermal shock conditions.
3. Low Thermal Conductivity
The thermal conductivity of Kerui ceramic fiber blankets is low. The thermal conductivity is between 0.09-0.76 W/mK at 400-1000°C. This provides good thermal insulation for the furnace.
4. Strong Mechanical Properties
Ceramic fiber blankets have strong mechanical properties, such as tensile strength, wear resistance, tear strength, elasticity, and so on. This gives them good anti-deformation ability in the kiln, like ceramic fire board.
5. Chemical Corrosion Resistance
Ceramic fiber blankets have good chemical stability. They can resist most acidic and alkaline chemical erosion. In addition, they have good high temperature oxidation resistance in industrial applications.
6. Noise Reduction
Ceramic fiber blankets have a porous structure, high density and light weight. They can effectively absorb sound waves and block sound transmission. This can improve the high temperature working environment.
