Application and performance characteristics of aerogel felt in the cold chain

In cold chain logistics, it is important to maintain the stability of the temperature of the goods.Traditional thermal insulation materials used in the field of cold chain have gradually failed to keep up with market demand due to their large thickness, poor fire resistance, long-term use and water intrusion, resulting in reduced thermal insulation performance and short service life.
As a new type of insulation material, aerogel felt has the advantages of low thermal conductivity, light material, and good fire resistance. It is gradually used in cold chain logistics.

Performance characteristics of aerogel felt
Aerogel felt is a new type of insulation material made of fiber (glass fiber, ceramic fiber, preoxygenated silk fiber, etc.) and aerogel, which has the following characteristics:
1. High thermal insulation performance: The thermal conductivity of aerogel felt is extremely low, much lower than that of traditional thermal insulation materials, which can effectively maintain temperature and reduce temperature fluctuations during cold chain transportation.
2. Lightweight and thin type: Aerogel felt has the characteristics of lightweight and thin type, which can be easily attached to the surface of the goods without increasing transportation costs and difficulties.
3. High strength: aerogel felt has high strength and toughness, can withstand extrusion and vibration during transportation, and ensure the safety of the goods.
4. Environmental protection: The use of aerogel felt will not cause pollution to the environment, which is in line with the environmental protection concept of modern logistics.

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

2. Protective layer for cooling medium
Aerogel felt can also be used as a protective layer for cooling media.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, the dew point problem is prone to occur, that is, the water vapor in the air condenses into water during the supercooling process, causing the cold chain equipment to condense.As a protective layer, aerogel felt can reduce the formation of condensate and avoid condensation problems.

4. Transformation of refrigerated trucks
Refrigerated trucks are one of the important means of transportation in cold chain logistics.However, traditional refrigerated trucks often have poor thermal insulation effect and high energy consumption.By using aerogel felt to transform the refrigerated truck, the thermal insulation performance and energy utilization efficiency of the refrigerated truck can be effectively improved, and operating costs can be reduced.
As a new type of thermal insulation material, aerogel felt can be used in the field of cold chain to play a role in thermal insulation, solving condensation problems, energy saving and emission reduction.
