Cold chain vehicle logistics, as an important type of cold chain logistics, has developed rapidly in modern society. In addition to meeting national vehicle standards, the structural design of vehicles should also have appropriate strength and stiffness, lightweight design, simple process, serialization, universality and standardization, good insulation performance and value, and easy maintenance. What are the good materials for Chongqing refrigerated trucks.

1. Insulation material and thickness
(1) Uniform foaming and low density;
(2) The thermal conductivity should be as small as possible, generally below 0.045w/(m2k);
(3) The stability of temperature changes is good, and the performance meets the requirements within the range of -4070 ℃.
(4) Has some mechanical strength and can withstand the vibration, impact, and deformation of small refrigerated trucks under harsh road conditions.
(5) Good water absorption, corrosion resistance, and antifreeze performance
(6) When using and burning insulation materials, there are no toxic, odorless, or harmful gases
(7) This utility model has the advantages of low cost and easy molding. The insulation layer of the small compartment can be formed by filling, pouring, spraying and other processes.
2. Insulation type
At present, there are two kinds of thermal insulation materials for small refrigerated vehicles: polystyrene foam and polyurethane foam. Polystyrene foam is a kind of foam material with porous honeycomb structure, which is heated by liquid foaming agent with low density.
Understanding the box material of refrigerated trucks can help to better purchase them.
