Construction Aerogel Thermal Insulation Material Blanket

Nano-aerogel felt is soft, easy to cut, low density, inorganic fireproof, overall hydrophobic, green and environmentally friendly. It can replace the traditional non-environmental and poor thermal insulation properties of glass fiber products, asbestos insulation felts and silicate fiber products. Flexible insulation material.

Nano aerogel felt is mainly used in industrial pipelines, storage tanks, industrial furnaces, power plants, rescue cabins, warship bulkheads, motor trains, direct buried pipelines, injection molding machines, detachable insulation jackets, heavy oil mining high temperature steam pipelines, transportation Thermal insulation in the fields of transportation, household appliances, steel, non-ferrous metals, glass, etc.

Nano aerogel felt physical properties:

Silica Aerogel Insulation Blanket Features:

1. Excellent heat insulation effect

The aerogel felt has a thermal insulation effect of 2-5 times that of the conventional insulation material, and the theoretical service life measured according to the Arrhenius experiment is 20 years. Almost the same life as the building.

2, reduce the thickness of the insulation layer

The aerogel felt achieves the same thermal insulation effect and is only a fraction of the thickness of conventional 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, water repellency and fire resistance

Aerogel felt water can effectively prevent moisture from entering the pipeline and equipment. At the same time, it has the fireproof performance of building A1 grade, and the unique three-dimensional network structure of aerogel avoids the phenomenon that the thermal insulation effect of other thermal insulation materials such as sintering deformation and sedimentation is significantly reduced in long-term high temperature use.

4, convenient construction

The aerogel felt is light, easy to cut and sew to accommodate various shapes of pipes and equipment, and requires less time and labor for installation.

5, save transportation costs

The smaller package size and lighter weight can greatly reduce the transportation cost of the insulation material.

Advantages of nano aerogel insulation felt:

First, the application in the high temperature industry

Nano-aerogel felts are the best choice for equipment that requires insulation while requiring small size and light weight. For example, ladle, torpedo, tundish, etc. in the metallurgical industry can realize the expansion of these devices by using nano-aerogel felt without changing the steel structure, and at the same time, can achieve a good thermal insulation effect. On a 100-ton steel ladle in a steel mill, the nano-aerogel felt was used instead of the traditional heat-insulating board to carry out the experiment. The test results are as follows:

1. Under the condition of the same thickness of the heat insulating material, the temperature of the outer wall of the ladle using the nano aerogel felt is 100-130 lower than that of the outer wall of the ladle using the traditional heat insulating board, which effectively reduces the thermal deformation of the ladle shell. .

2. Under the condition that the outer wall temperature of the ladle is the same, the 20mm thick nano-aerogel felt can replace the traditional heat insulation board of 30mm thickness to realize the expansion of the ladle.

3. Using nano-aerogel felt, the molten steel in the ladle is cooled slowly, which is conducive to the stability of the molten steel temperature.

4. It has good chemical stability, and it does not decompose, degrade, and not powder
