Insulation material-aerogel felt

Aerogel felt is a grade A1 inorganic fireproof material for buildings. Its thermal conductivity at room temperature is 0.018W/(K m), and it is absolutely waterproof. Its thermal insulation performance is 3 to 8 times that of traditional materials. It can replace glass fiber products, asbestos insulation felt Silicate products and other traditional flexible materials that are not environmentally friendly and have poor thermal insulation performance. aerogel felt is a flexible insulation felt made of nano-silica aerogel as the main material, which is compounded with glass fiber cotton or pre-oxidized fiber felt through a special process. It is characterized by low thermal conductivity, certain tensile and compressive strength, and is convenient for thermal insulation construction application. It is a new type of thermal insulation material.

Aerogel felt is a flexible thermal insulation material that uses silica aerogel as the main material and is compounded in reinforcing fibers, such as glass fibers and pre-oxidized fibers, through a special process.

Comparison of aerogel and traditional materials

Aerogel felt is currently the solid thermal insulation material with the lowest thermal conductivity in the temperature range of about 400°C (the thermal conductivity in the high temperature range of 400-1000°C is much higher than that of the micro-nano thermal insulation series).

Aerogel felt has the characteristics of softness, easy cutting, low density, inorganic fire prevention, overall hydrophobicity, green environmental protection, etc. It can replace traditional flexible materials such as glass fiber products, asbestos insulation felts, and silicate fiber products that are not environmentally friendly and have poor thermal insulation performance. Insulation Materials.

Aerogel felt is mainly used in industrial pipelines, storage tanks, industrial furnaces, power plants, rescue cabins, bulkheads of warships, motor vehicles, direct buried pipelines, injection molding machines, detachable insulation sleeves, high-temperature steam pipelines for heavy oil exploitation, transportation , Household appliances, steel, non-ferrous metals, glass and other fields of thermal insulation.

 Advantages

1. Excellent heat insulation effect

The thermal insulation effect of aerogel felt is 2-5 times that of traditional thermal insulation materials, and the theoretical service life determined by the Arrhenius experiment is 20 years. Almost as long as the building.

2. Reduce the thickness of the insulation layer

Aerogel blanket achieves the same thermal insulation effect, and the thickness is only a fraction of that of traditional materials. After heat preservation, the heat loss is small and the space utilization rate is high. And at high temperature, the above performance advantages are more obvious.

3. Hydrophobicity and fire resistance

The aerogel blanket is absolutely hydrophobic, which can effectively prevent moisture from entering the pipeline and the interior of the equipment. At the same time, it has the building A1 fireproof performance, and the unique three-dimensional network structure of airgel avoids the obvious decline in the insulation effect of other insulation materials such as sintering deformation and settlement during long-term high-temperature use.

4. Convenient construction

Aerogel blanket is light in weight, easy to cut and sew to adapt to various shapes of pipes and equipment insulation, and requires less time and manpower for installation.

5. Save transportation costs

Smaller package volume and lighter weight can greatly reduce the transportation cost of insulation materials.
