4.2 How to choose a refrigerated truck ? In recent years, refrigerated trucks have become more and more popular, and fast-paced life has also driven the development of fast foods to a certain extent, driving the market for refrigerated trucks. At present, the safety of refrigerated foods has gradually been taken seriously by the country. At the same time, the use of refrigerated trucks to transport frozen foods has become a trend. Then, when choosing a refrigerated truck, you need to choose from many aspects. 4.2 How to choose a refrigerated truck ? Let's take a look!
When a user chooses to purchase a refrigerated truck, not only must the overall economy be considered, but also its functionality, such as the effect and quality of refrigerated insulation, must be taken into consideration. The refrigerators used in the market have a length of 4 meters to 4.2 meters. For 4.2 refrigerated trucks, its models are mainly Dongfeng Freka refrigerated trucks, Foton Era refrigerated trucks, and JAC Shuai Ling refrigerated trucks. Foton Aoling refrigerated trucks, etc., mostly use diesel engines. At the same time, most of them are non-independent refrigeration units. The cooling temperature can be controlled at -18 degrees. Many of the refrigerator cars in the market are equipped with an integrated skeleton “sandwich†plate bonding process. Most of the surrounds of this type of car body are aluminum alloy edging. The floor of the car body is made of in-situ cast glass steel plate. , The overall insulation is good, while the overall strength. It should be noted that the floor of the tank will be equipped with ventilation slots to facilitate the cooling of the entire vehicle, so as to ensure a balanced temperature within the vehicle body.
4.2 How to choose a refrigerated truck ? Knowing from the use of your refrigerated truck to understand whether it is used to transport frozen foods, dairy products, fruits and vegetables, or to transport vaccine drugs, this can first help you make a choice in the cooling effect, and at the same time the thermal insulation of refrigerated trucks Selections can also be made on various options such as the car body, the refrigeration unit, and the hook car. The choice of refrigeration unit needs to consider whether it is simple in structure, convenient in operation, reliable in operation, low in energy consumption, large in cooling capacity, and in noise.
Aluminum Deep Drawing Sheet is a kind of Aluminum Sheet suitable for deep drawing process.It has wide applications.The advantage of aluminum deep drawing sheet is as follows:
1. Easy to process.
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
