The refrigerator car is composed of chassis, refrigerator and box, the chassis is the core, the refrigerator is the brain and the box body embodies the soul of the whole, and the three are indispensable; The refrigerator unit of the refrigerator truck is responsible for the temperature supply, and the box is responsible for the temperature maintenance. If the refrigeration unit is the energy supplier, the box will become the energy storage. The quality of the refrigerator box directly affects the service life of the refrigerated vehicle. The advantages and characteristics of the refrigeration products of Tuolu star brand are as follows:

Insulation:

The box of Tuolu star refrigerator car is made of FRP, the interlayer insulation adopts polyurethane high-quality materials, and polyurethane is made by cutting after outdoor foaming. It has uniform foaming, high density, high strength and small thermal conductivity. The dry-type plate used in the box type is formed by one-time hot pressing by high temperature and high pressure hot press, which prevents the thermal conductivity from the outside air.

Sealing:

The fully closed plate block structure adopted for box splicing adopts imported large board adhesive, with large contact area, uniform stress distribution, and no heat conduction of air. The sealing effect of this assembly method is good, and there is no long time. Cracks appear in the connecting part of the box, the appearance of water seepage and air heat conduction. The back door of the box adopts the imported interior The outer double layer sealant strip can completely isolate the air inside and outside the box, and can not form the air inside and outside circulation.

Light weight:

The non-metallic materials used in the cold box structure of Shandong Tuolu modification Co., Ltd. have no metal skeleton, so as to avoid the formation of cold bridge; The outer part of the box is decorated with aluminum alloy, and the weight of the overall refrigerated box is more than 30% lighter than that of metal and color steel plate.

Corrosion resistance:

The inside and outside of the box is made of glass plate, which is hard material resistant to acid and alkali, and does not produce any chemical reaction.

Anti aging and long service life:

The main components of FRP material are glass fiber and resin curing synthesis, the box after curing has high strength, strong steel, high temperature resistance, wear resistance, high smoothness and easy to clean; The degradation time of the material in the soil is 80-100 years, which ensures the aging resistance and service life of the material.

Easy to maintain:

The box is made of high-strength fiberglass steel inside and outside, and polyurethane is used for bonding inside. It is made by reaction of hot pressing technology. The structure itself is not easy to damage and stability. If necessary, repair where damage is convenient and quick.
