Dongfeng Tianjin refrigerated truck is mainly a closed box transporter for transporting frozen or high-quality goods. It is a refrigerating device equipped with a refrigeration unit and a refrigerated transport vehicle with integral injection structure. It is commonly used in the transportation of frozen foods, dairy products, fresh fruits and vegetables, vaccines and drugs. Therefore, the refrigerating performance and sealing performance of the refrigerated truck must be high and the thermal conductivity must be low in order to ensure that the transported matter will not be degraded in transit.
The overall injection structure of the Dongfeng Tianjin refrigerated truck is divided into three stages of development. The first stage is the overall injection of foamed metal skin structure. This kind of product structure is easy to form a large number of cold bridges due to the presence of a large number of metallic materials on the car body, but because the defects injected into the foamed heat insulation layer are not easy to find, the inherent quality is not easy to guarantee, and the foamed material is used as the heat insulating material. As a binder, it is easy to produce defects such as poor adhesion, resulting in less satisfactory heat insulation and higher heat leakage. The second phase is injected into the foamed glass steel structure as a whole. On the basis of the first phase, some targeted improvements were made. The weight was lighter, the heat loss rate was reduced, and the heat preservation effect was also good. However, there were problems such as weak adhesion and easy formation of bubbles outside the car cabin. . Therefore, in the third development stage, this defect is minimized and the whole is injected into a fully-enclosed polyurethane plate bonded glass steel structure. This product structure is light in weight, low in heat leakage, and good in heat preservation. The unsaturated polyester resin is used as a binder, and a mat layer is additionally added. A rigid polyurethane foam is used for the heat-insulating material, so that the thermal conductivity can be minimized and the strength can be high. High-strength, high-seal adhesive for plate bonding. The only downside is the large loss after polyurethane cutting, so the material cost is higher. However, this type of refrigerated truck dominates the market of China's refrigerated trucks and is the technology used by China's refrigerated truck manufacturers. Dongfeng Tianjin Refrigerator Truck continued to improve the overall injection structure, so that the cold storage performance of the carriage is even higher.
The continuous improvement of Dongfeng Tianjin refrigerated trucks has enabled more businesses to choose Dongfeng Tianjin refrigerated trucks to transport their product materials. Therefore, only by continuous improvement can we usher in a larger market in order to compete better.
