In cold chain logistics, it is important to keep the temperature of the goods stable. Traditional thermal insulation materials used in the cold chain field gradually cannot keep up with market demand due to the use of large thickness, poor fire performance, long-term use of water intrusion resulting in reduced thermal insulation performance, short service life and other problems. As a new type of thermal insulation material, aerogel felt is gradually applied in cold chain logistics with its advantages of low thermal conductivity, light material and good fire resistance.

First, the performance characteristics of aerogel felt

Aerogel felt is a new type of insulation material made of fiber (glass fiber, ceramic fiber, pre-oxygenated silk fiber, etc.) and aerogel, which has the following characteristics:

1, high thermal insulation performance: the thermal conductivity of aerogel felt is very low, much lower than that of traditional thermal insulation materials, which can effectively maintain the temperature and reduce temperature fluctuations during cold chain transportation.

2, light and thin: aerogel felt has the characteristics of light and thin, can be easily attached to the surface of the goods, will not increase the cost and difficulty of transportation.

3, high strength: aerogel felt has high strength and toughness, can withstand extrusion and vibration during transportation, to ensure the safety of goods.

4, environmental protection: the use of aerogel felt will not cause pollution to the environment, in line with the environmental protection concept of modern logistics.

Second, the application of glass fiber aerogel felt in cold chain

1, used for heat insulation layer

Aerogel felt can be used as insulation. Because the material has an extremely low thermal conductivity (at the test temperature of -25 ° C, its thermal conductivity is only 0.015 w/m·k), it can effectively reduce the conduction and loss of heat in the cold chain system, ensuring the temperature stability of refrigerated or frozen goods. At the same time, the glass fiber aerogel felt also has excellent flexibility, can be cut and installed according to different shapes, to adapt to different cold chain system needs.

2. Protective layer for cooling medium

Aerogel felt can also be used as a protective layer for the cooling medium. In cold chain transportation or storage, protecting the cooling medium from external heat interference can improve the cooling effect and maintain the low temperature state of the cooling medium.

3. Solve the condensation problem

In the cold chain system, it is easy to have the dew point problem, that is, the water vapor in the air condenses into water during the supercooling process, resulting in condensation of the cold chain equipment. The aerogel felt as a protective layer can reduce the formation of condensation and avoid condensation problems.

4, refrigerated truck transformation

Refrigerated truck is one of the important means of transport in cold chain logistics. However, traditional refrigerated trucks often have poor insulation effect and high energy consumption. The heat insulation performance and energy efficiency of refrigerated trucks can be improved effectively by using aerogel felt to transform them, and the operating cost can be reduced.

As a new type of thermal insulation material, aerogel felt can play a role in the field of cold chain heat preservation and insulation, solve the problem of condensation, energy saving and emission reduction.
