Foods that need to be refrigerated, such as fresh fruits, need cold chain logistics during transportation. They are more complex and complex than the normal temperature logistics system, and the construction investment is much larger. It is a huge system project. Because the timeliness of perishable foods requires higher organization and coordination of the cold chain, the operation of the food cold chain is always linked to energy costs. Effective control of operating costs is closely related to the development of the food cold chain. Tradematt aerogel cold storage insulation materials With its low thermal conductivity and excellent thermal insulation properties, it can save energy costs and help the rapid development of food cold chain.
Judging from the status quo and development trend of cold storage, the constant-temperature air-conditioned storage of fruit products has developed rapidly and the proportion of low-temperature storage has increased. China's domestic cold-storage industry is moving toward lightweight prefabrication, cryogenics, and management using aerogel cold storage insulation materials. Automated loading and unloading cargo handling, constant temperature evaporating of cold storage of fruits and vegetables, replacement of chillers by chillers, and Freon refrigerants are widely used, flexible, diverse, efficient, safe, and environmentally friendly. Cold storage is a large energy consumer. The data shows that the increase of 0.1mm in the oil film in the evaporator will reduce the evaporation temperature by 2.5 °C and increase the electricity consumption by 11%. If there are oil film and scale in the condenser, the appearance of frost on the evaporator will cause the evaporation temperature to drop, and the power consumption will increase.
The advantages of Tradematt aerogel cold storage insulation materials in the use of cold chain logistics and refrigerated cold storage:
1. Excellent insulation performance:
Aerogel cold storage insulation materials As a new type of thermal insulation material, Tradematt aerogel cold storage insulation materials have excellent thermal insulation properties. When the test temperature is 25°C, the thermal conductivity is 0.018 w/m·k; under low temperature conditions At a test temperature of -25°C, the thermal conductivity is only 0.015 w/m·k; while for a polyurethane (PU) at a test temperature of -25°C, the thermal conductivity is 0.026 w/m·k; For VIP vacuum insulation panels, the aerogel insulation material has better dynamic insulation effect and can be recycled. Therefore, when the temperature is low, it can achieve the same insulation effect. The aerogel insulation felt can use thinner insulation thickness than polyurethane (PU).
2. Extraordinary durability:
Aerogel cold storage insulation materials The unique nano three-dimensional network structure provides excellent insulation stability, avoiding the phenomenon that traditional materials are prone to stacking deformation for a long time and the insulation effect is drastically reduced.
3. Excellent water resistance:
The overall lotus-like drowning effect, drowning rate ≥99.6%, excellent overall waterproof performance.
4. Excellent compressive, tensile and crack resistance:
Aerogel cold storage insulation materials Excellent physical properties, resistance to brute force construction and alternating hot and cold internal stress, long-term use without settlement, no deformation. Easy to dismantle, short construction period, good airtightness, and high space utilization.
5. High quality and environmentally friendly products:
Tradematt aerogel cold storage insulation materials Chemical stability, the use of harmful substances in the process of the volatilization, but will not decompose or mold, have good corrosion resistance. In the production process, no harmful gas is produced, and the environmental protection concept is also embodied in the production process. The solid waste generated can be recycled and treated, and it is an environmentally friendly product that can be recycled.
