The selection of the cabin plate of the cold chain car can be viewed from three aspects:

First, heat insulation performance.

The heat insulation performance of the refrigerated thermal insulation body is inseparable from its structure and material, so special attention should be paid to the purchase of refrigerated trucks. The material plate with good thermal insulation and thermal insulation performance means that the thermal insulation time is long, the working time of the refrigerator is short, and the fuel consumption is also reduced, which plays the role of energy saving and emission reduction.

Second, light weight, strong structure.

Body weight, fuel consumption during transportation; On the contrary, the car is light and consumes less fuel during transportation. The thermal insulation layer of the cold chain refrigeration and insulation body is made of foamed polyurethane, the internal and external surfaces of the car are made of FRP glass steel plate, and the envelope of the body is also made of lightweight aluminum material. The whole body is about 20% lighter than the body made of sandwich, and the structural strength is also much higher.

Third, corrosion resistance, no pollution, strong anti-aging.

A good refrigerated and insulated carriage, its inner and outer skin should be made of high-quality glass steel plate (FRP). The interior and exterior surfaces of some refrigerated trucks are color-coated steel plates. The test shows that the corrosion resistance of FRP is 3-5 times that of ordinary metal materials, and it is easy to repair. Therefore, the service life of the refrigerated insulation body will be greatly extended, and the service life of the good insulation body will reach 15 years or even 20 years.
