Refrigerated car body production technology:
1. The “sandwich†plate bonding type of split sheets is assembled. At present, larger refrigerated truck manufacturers in China have adopted this technology. Refrigerator vehicles produced using this technology have higher heat insulation performance.
2. Fragmented injection foam type.
3, the overall skeleton injection foam type.
4. Vacuum Adsorption Paste Refrigeration Units Category: Refrigeration units are divided into non-independent refrigeration units and independent refrigeration units. Domestic units and imported units. General models use external coolers, and a few mini-refrigerators use built-in coolers. For refrigerators with lower temperature requirements, a built-in cold plate (functionally equivalent to an evaporator) can be used
To think of the insulation effect of the car body, it is naturally the choice of insulation material.
The advanced refrigerated car insulation car has high requirements for the insulation material:
(1) Uniform foaming and low density;
(2) The thermal conductivity is as small as possible, generally less than 0.045 W/(m?K);
(3) The stability to temperature changes is better, and the performance must meet the specified requirements within the temperature range of -40 to 70 °C;
(4) Has a certain mechanical strength, can withstand the vibration and impact of the car in bad road conditions without damage or deformation;
(5) Low water absorption and moisture absorption, good frost resistance;
(6) Non-toxic, odorless, low air permeability, no toxic and harmful gases can be decomposed when the heat-insulating material burns
(7) The price is low and it is easy to form. It can be filled, poured, sprayed and other processes to form the heat insulation layer of the carriage.

Aluminum Anodized Sheet is one type of Aluminum Sheet which has surface anodized treatment.Aluminum anodized sheet is good in performance condition which requires high corrosion resistance.Regularly after casting the aluminum sheet,the surface of the sheet is with natural oxide film which is good to prevent the aluminum sheet from oxidation.Also the aluminum anodized sheet is with a shining surface sometimes which is good in some application which requires good surface condition.However,the anodic oxidation process is very costly and it requires lots of treatment in the wastage.Hence the cost of the aluminium anodized sheet will be higher than regular sheet as well.
Trust in harmony,we care what our clients care.We hope to bring better future for our next generation.
