NANO Pyrogel Aerogel Silica Aerogel insulation Fabric

Aerogel insulation felt is divided into special felt and general felt. The difference is divided according to the thickness of the hair, the size of the density and the difference of the color; the technical requirements are divided according to the presence or absence of strength, elongation and capillary action, which can be checked during acceptance.

The aerogel insulation felt is obviously a quilt with good thermal insulation effect. The ideal insulation felt should have the advantages of small heat transfer coefficient, good heat preservation, moderate weight, easy winding, good wind resistance, good waterproofness and long service life.

Aerogel insulation blankets are widely used, such as greenhouse insulation, greenhouse insulation, automobile insulation, curtains, building insulation, concrete insulation, construction insulation, engineering insulation, road insulation and other purposes.

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

Application areas:

Metallurgy: ladle, ladle, tundish, converter, torpedo

Machinery: industrial furnace, electric furnace, furnace door, furnace cover

Automotive: engine heat shield, catalytic exhaust pipe

Petrochemical: cracking furnace, reforming furnace, heating furnace

Electricity: boilers, steam turbines, pipelines

Building materials: ceramic furnace, rotary furnace

Effect:

Reduce the thickness of the insulation

Since the thickness of the hot layer can be greatly reduced, the heat insulating device can be miniaturized and the volume of the device can be increased.

Reduce heat storage

Reducing the heat storage capacity of the insulation layer and greatly shortening the heating time of the kiln, so that not only energy saving, Tianjin Gute nanoporous insulation material can achieve productivity and easy temperature control.

Reduce heat dissipation

Since the use of thinner nanoporous insulation material can achieve thermal insulation, it can reduce the heat dissipation surface area and greatly reduce heat loss. Therefore, the surface temperature of the kiln can be lowered and the working environment can be improved.

Temperature uniformization

By reducing the effect of heat loss, the temperature can be maximized, and as a result, the temperature of the metal solution, the glass solution, and the heat treatment product of the kiln can be more uniform, and the product quality can be improved.
