Why is Kerui Aluminum Silicate Blanket Resistant to High Temperature?
Unique Material Composition
The main components of aluminium silicate high temperature insulation ceramic fiber blanket include Al2O3 and SiO2. This fiber has a high melting point and high thermal stability.
Excellent Fiber Structure
Its fibers are interwoven in an orderly manner to form closed insulation chambers. They can effectively prevent heat transfer. Therefore, aluminum silicate fiber blankets can maintain a low temperature rise in high temperature environments.
Special Manufacturing Process
Kerui aluminum silicate ceramic blanket adopts continuous spinning process to form fiber and double-sided needle punching. In addition, as refractory suppliers, we will perform heat treatment through a fully automatic blanket heating furnace. This can pre-phase change the aluminium silicate high temperature insulation ceramic fiber blanket and reduce its high temperature shrinkage during use.
Application of Aluminum Silicate Fiber Blanket
The alumina ceramic thermal blanket conductivity is low. So it is widely used in steel, petrochemical, electric power, metallurgy, aerospace and other industries. Here are its specific uses.
- High temperature pipelines, industrial kiln wall lining;
- Kiln door top cover insulation;
- Stress relief insulation for welded parts and special-shaped metal castings;
- Heat insulation for power boiler turbines and nuclear power;
- Filtration of high temperature gases and liquids;
- Used for fireproof rolling shutter doors and fireproof doors;
- Can be made into ceramic fiber module.

High Quality Aluminum Silicate Blanket
Kerui uses excellent raw materials and dedicated purification and mixing production processes. This effectively reduces the impurity content in the zr al insulation blanket. Thus, the thermal stability of the product is improved. Moreover, it is 1.2 times the energy-saving capacity of similar thermal insulation materials such as insulation brick.
Diverse Choices
We can customize the appropriate specifications and thicknesses according to the different application needs of customers. For example, for processes with different temperature levels and refractory requirements, Kerui can provide aluminum silicate blankets with different densities.
Excellent After-sales Service
Kerui is able to help customers solve various problems that may be encountered during installation and use. In addition, the company also provides regular maintenance services. We ensure the long-term stability of aluminum silicate blankets and help customers improve the operating efficiency of equipment. In addition, you can also watch the video of Kerui’s ceramic fiber blanket quality inspection on YouTube.
