Properties and Advantages of Nano Aerogel Felt

wallpapers Industry 2020-08-04

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

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 the micro-nano thermal insulation series).

Aerogel felt has the characteristics of softness, smooth cutting, low density, chemical fire resistance, overall hydrophobicity, and green 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 poorer 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 felt1. Excellent heat insulation effect

The thermal insulation effects of aerogel felt is 2-5 times that of traditional thermal insulation materials. The theoretical high-temperature pipeline service life determined by the 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 visible.

3. Hydrophobicity and fire resistance

Aerogel felt it is relatively hydrophobic, which can effectively prevent water from entering the pipeline and equipment. At the same time, it has to build A-level fire protection performance. The unique three-dimensional network structure of aerogel prevents other thermal insulation materials from sintering deformation and sedimentation during long-term high-temperature use.

4. Convenient construction

Aerogel felt it 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 significantly reduce the transportation cost of insulation materials.
