What are the advantages of aerogel felt

Overview of Aerogel Felt

Aerogel felt is a flexible thermal insulation felt made of nano-silica or metal aerogel as the main material, combined with carbon fiber or ceramic glass fiber wool or pre-oxidized fiber felt through a special process. It is characterized by low thermal conductivity, certain tensile and compressive strength, and is a new type of pipeline insulation material.

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

Aerogel felt has the lowest thermal conductivity of solid thermal insulation materials in the 400℃ temperature range (the thermal conductivity of the 400-1000℃ high temperature region 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 resistance, overall hydrophobicity, and environmental protection. It can replace glass fiber products, asbestos insulation felt, silicate fiber products and other traditional flexibility that are not environmentally friendly and have poor thermal insulation performance. Insulation Materials.

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

Advantages of aerogel felt

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 high-temperature pipe service life determined by Arrhenius experiment is close to 20 years.

2. Reduce the thickness of the insulation layer

Aerogel felt achieves the same thermal insulation effect, and its 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 temperatures, the above performance advantages are more obvious.

3. Hydrophobicity and fire resistance

Aerogel felt is relatively hydrophobic, which can effectively prevent water from entering the pipeline and equipment. At the same time, it has Class B1 to Class A fire resistance, and the unique three-dimensional network structure of aerogel avoids the obvious decline of other thermal insulation materials such as sintering deformation and sedimentation during long-term high-temperature use.

4. Convenient construction

Aerogel felt is light in weight, easy to cut and sew to adapt to various shapes of pipes and equipment for heat preservation, and it requires less time and labor for installation.

5. Save transportation costs

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

Application of aerogel felt

Nano aerogel felt is a material with excellent heat insulation performance. Its pore size is smaller than the mean free path of air molecules under normal pressure. Therefore, the air molecules in the aerogel voids are approximately static, thereby avoiding convective heat transfer between air and condensation. The extremely low packing density of the colloid and the curved path of the nano-grid structure also prevent the heat conduction of gases and solids, and the void walls can minimize heat radiation. These three aspects work together to block almost all heat transfer methods. Aerogel achieves a thermal insulation effect that other materials can't match, and it is even far lower than the thermal conductivity of a small amount of air at room temperature of 0.025W/mK, reaching below 0.018W/mK.

Aerogel felt is mainly used in industrial pipelines, storage tanks, industrial furnace bodies, power plants, rescue cabins, warship bulkheads, automobiles, directly buried pipelines, injection molding machines, detachable insulating sleeves, high-temperature steam pipelines for heavy oil mining, and Transportation, home appliances, steel, non-ferrous metals, glass and other thermal insulation fields.
