Nano aerogel felt is a material with excellent heat insulation performance

Overview of Aerogel Felt

Aerogel felt is a kind of flexible thermal insulation material that uses silica aerogel as the main material and combines glass fiber, pre-oxidized fiber and other reinforcing fibers through a special process.

Aerogel felt has the lowest thermal conductivity among solid thermal insulation materials in the temperature range of 400°C (the thermal conductivity in the high temperature zone 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 resistance, overall hydrophobicity, and environmental protection. It can replace glass fiber products, asbestos thermal insulation felt, silicate fiber products and other traditional flexible thermal insulation materials that are not environmentally friendly and have poor thermal insulation performance.

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 pipeline service life determined by Arrhenius experiment is close to 20 years.

2. Reduce the thickness of the insulation layer

Aerogel felt has the same thermal insulation effect, its thickness is only a fraction of that of traditional materials, the heat loss after thermal insulation 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

The aerogel felt is relatively hydrophobic, which can effectively prevent water from entering pipes and equipment. It also has B1 to A fire resistance. The unique three-dimensional network structure of aerogel prevents other thermal insulation materials from sintering and long-term high temperature deformation and sedimentation.

4. Convenient construction

The aerogel felt is light in weight, easy to cut and sew, suitable for various shapes of pipes and thermal insulation equipment, and saves time and effort during installation.

5. Save transportation costs

Smaller packaging volume and lighter weight can greatly reduce the transportation cost of insulating 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 unmatched by other materials, 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 extraction, and transportation , Home appliances, steel, non-ferrous metals, glass and other thermal insulation fields.
