First, the application in the high temperature industry
Nano - aerogel insulation felt is the best choice for equipment that requires insulation while also requiring small volume and light weight. Such as steel ladles, torpedo cans, tundish and the like in the metallurgical industry, the expansion increment of the equipment can be realized by utilizing the nano aerogel thermal insulation felt on the premise of not changing the steel structure, and meanwhile, good thermal insulation effect can be achieved. In a steel plant 100 tons of steel ladle, using nano aerogel insulation blanket instead of the traditional insulation board experiment, the test results are as follows:
1. under the condition that the thickness of the heat insulation material is the same, the temperature of the outer wall of the steel ladle by using the nano aerogel heat insulation felt is reduced by 100 - 130 compared with the temperature of the outer wall of the steel ladle by using the traditional heat insulation board, so that the thermal deformation of the steel ladle shell is effectively reduced.
2. under the same temperature of outer wall of ladle, 20 mm thick nano aerogel insulation felt can replace 30 mm thick traditional insulation board to realize the expansion increment of ladle.
3. using nano aerogel insulation felt, the temperature of molten steel in the ladle is obviously slow, which is beneficial to the stability of the temperature of molten steel.
4. it has good chemical stability, no decomposition, no deterioration and no pulverization after repeated use.
Second, the development and application of nano aerogel insulation felt
Application prospect: because that production proces of the nano aerogel thermal insulation felt is formed by hydraulic compression mol, different abrasive tools can be adopted to produce the nano aerogel thermal insulation felt with different shapes accord to requirements, and the nano aerogel thermal insulation felt is applied to different fields. At that same time, accord to the requirements of different temperature, heat insulation materials used at different temperatures are produce. The material for producing the nano aerogel thermal insulation felt does not contain harmful substances, is an environment-friendly material, and can be applied to thermal insulation of household appliance products. Due to the good thermal insulation performance of the nano aerogel thermal insulation felt, the thickness of the thermal insulation material can be greatly reduced in use, so that household appliance products are smaller and more energy - saving. Compared with the traditional thermal insulation materials, the nano aerogel thermal insulation felt with excellent performance at the temperature of 350 - 1000 deg c has lighter weight, smaller volume and thinner thickness. The development of flexible aerogel thermal insulation felt can be applied to heat insulation systems such as pipelines, aircraft, automobiles and the like. Nano aerogel thermal insulation felt can be used in aerospace, petrochemical and other important fields due to its super thermal insulation performance. In a word, the development and application of nano aerogel insulation felt will have a broad prospect.
