4.2 meters refrigerated car is good?
4.2 meters refrigerated car is good? As we all know, a closed transport vehicle that is used for transporting frozen foods or fresh goods for refrigerated trucks is different from the refrigeration units equipped with refrigeration units. One of the most popular car types on the market today is the 4-4.2 meter refrigerated truck. What are the advantages of the 4.2 meter refrigerated truck? What is the life of the refrigerated truck? First of all, when choosing a refrigerated truck, it is necessary to understand the overall structure, such as the insulation cabin, the refrigeration unit, and the temperature recorder inside the cabin. For the more demanding refrigerated trucks, optional equipment such as hook trucks and ventilation slots also need to be considered. Refrigerator cars need to consider several points, the car body is good insulation, thermal insulation performance, smooth draft, good resistance to the atmosphere, water, acid and alkali, salt, etc., as well as anti-aging properties to ensure the good transport of various goods At the same time, it needs good impact resistance. Refrigerated vehicles are used for the long-distance transportation of fruits, vegetables, fresh milk, etc., which are easily deteriorated and rotted, and transport vehicles such as medical blood and vaccines require refrigerated trucks. Therefore, for refrigerated trucks, different types of cargo transportation have different cooling effects. The request. As for 4.2- meter refrigerated trucks, it is also necessary to consider the service life of refrigerated trucks. Generally speaking, the service life of refrigerated trucks has the following aspects: 1. The quality of refrigerated truck oil products; 2. The refrigerating truck lubricants. Quality; 3 , bad roads on refrigerated trucks; 4. Maintenance of refrigerated trucks after sale, etc. Of course, these are external factors that need to be considered. If the life of a refrigerated truck is required to be long, the quality of the refrigerated truck must be selected. The key equipment is the refrigerating unit of the refrigerated truck, which is very important for the continuous supply of cold goods. The equipment can generally be selected in accordance with the volume of the refrigerator body and the requirements of the goods to be transported to carry out the selection of different power refrigeration capacities. In addition, the refrigerated car's heat preservation box is also very important, the main role is to maintain the temperature, in the choice of insulation box to follow the insulation performance is good, not easy to damage and the weight to light three points can be. Zinc Die Casting Products are a metal forming process in which molten zinc metal is put under pressure and injected into a die.
Zinc Die Casting Products are efficient and economical and offers a wide range of durable shapes and components. Little or no machining is required after a part is die casted, because the process provides very close tolerances for even complex shapes. Zinc Die Castings can also be easily plated or finished. Zinc Die Casting Products are dimensionally stable and heat resistant.
Although this alloy exhibits excellent casting characteristics, it has seen limited use by die casters. It does however possess some interesting characteristics that may be of assistance to designers. Its creep performance is rated higher than the other zinc alloys and it maintains higher strength and hardness levels after long-term aging.

Zinc are alloys that have high strength and hardness, outstanding corrosion resistance,full recyclability, mechanical properties, high thermal and electrical conductivity and strength at high temperatures. Zinc alloys possess high dimensional stability for complex shapes and excellent thin walls. The cost of raw material is low.
The behavior of zinc alloys under stress is non-linear and time-temperature dependent on strain-rate, i.e. the ratio of stress to strain is not constant, even at low stresses, and varies with time resulting in continuous plastic flow under constant applied load. Designers of structural components should be aware of the creep limitations of zinc alloys, which do not have a single value for elastic modulus or yield strength. Yield strength (allowable stress) under sustained loading is dependent on the allowable design strain (% elongation) over the required service life. Working values for the elastic modulus and yield strength are important for design purposes. Standard engineering formulae used for calculating cross-sections of elastic materials must therefore be used with some caution.
This alloy exhibits excellent damping capacity and vibration attenuation in comparison with Aluminum Die Casting alloys.
