The pressing technology for truck body panel

Our truck body panel is fully enclosed composite sandwich structure, the inside and outside surface are the FRP sheet, the thermal insulation layer is rigid polyurethane foam, it is necessary to put into embedded parts, which bonded by glass fiber mat and resin adhesive after hot pressing.The panel structure should be molded without steel structure and cold bridge,the heat preservation performance is good, and with good waterproof performance at the same time, the panel should be high intensity, light weight,it can effectively solve the puzzles of bubble, wrinkles and other technical problems.we require high production efficiency and the production of cars inside and outside surface does not need to spray paint processing.And the surface flatness error should be controlled at 0.5 mm/m or less.

The bottom structure of refrigerated truck body

The bottom of refrigerated truck body adopts integral cast-in-place FRP, it owns good heat preservation performance, high strength, the ventilation slots design facilitate air circulation of whole vehicle, and a balanced load temperature was kept there.Due to the steel frame structure embedded parts in floor wall, the structure is pretty stable. The production of bottom panel is completed, the surface of the bottom plate is adhesive resin + glass fiber to meet the requirements of food grade glass reinforced plastics (FRP), it guarantee the good preservation performance and impact strength of bottom panel.

The application scope of PU composite panel

As building energy-saving insulation materials,Polyurethane composite panels has been widely used in Europe, America, Japan and other developed countries , the penetration rate reaches 80%, but less than 10% is applied in our country.Polyurethane sandwich board as a kind of excellent energy-saving insulation materials, its excellent heat insulation, fire prevention, heat preservation performance can provide efficient solutions to solve the crisis of China's energy consumption .Polyurethane sandwich panel is widely used in large industrial plants, cold storage, garage, mobile houses, pavilion, gymnasium, shopping centers, airports, power plants, villas, hospitals, formation and high-rise office buildings and other fields, because of the excellent heat preservation performance, it is mainly used in industrial and civil roof and wall construction.

The good performance of resin for FRP sheet

Good quality FRP sheet need high quality resin.The resin our used can resist the corrosion.It is resistant to acid of middle density, alkali, various salts environment, and the usage temperature is -50℃～90℃,the highest temperature is 105. The velocity of inflaming retarding is Grade One of ASTM E-84 ,and the flame spreading index is below 25. Another kind of ORP resin type can resist to seawater, weak acid and atmospheric aging environment, the usage temperature is -50℃～60℃, and the highest temperature is 100℃. This is the economical type. Compared with the traditional steel grating, aluminum grating and wood grating, its corrosion resistance is better though its corrosion resistance is weak in all of the resin types. The velocity of inflaming retarding is Grade One of ASTM E-84, and the flame spreading index is below 25.With this kind resin, our FRP sheet can be applied to many kinds of panel or other building purpose.

The comparison between FRP sandwich panel and metal sandwich panel.

The FRP sandwich panel is fabricated by FRP Sheet and Pu rigid foam,its internal and external coverings are integral FRP sheet. While the metal sandwich panel is fabricated by metal skin and XPS or injected PU, its internal and external coverings are individual metal skin.The structure of former one is all closed vacuumized homogeneous construction and without any metallic support frame inside.But the metal one is opened structure and non vacuuming processing, metallic support is put into the frame. The weight of the FRP one is 30% to 70% lighter than metal one.The FRP sandwich panel have excellent insulation.It is more reliable, effective and cost-saving.

The features of cold-chain?

Due to the tight connection to the quality of food, the cold chain is more complicted and supervised more strictly:

1.It is a huge systematic programme for more building invest than normal logistics system.

2.High organization is required for the pragmaticality of perishable food.

3.The operating cost is closely related to the energy cost, so to control the operating cost is important to the cols-chain.

What are the features of agricultural products cold-chain logistics?

The transportation of agricultural products is complicated, dynamic, intersectional, accrued and customized. Its features are as following:
1.the chain of agricultural is wide and short.The participant is large, and the market extend to a wide range.So, different kind of transportation chains are formed.The fresh agricultural products have a high demand for time.the short chain is suitable for agricultural products.
2. The transportation of agricultural products need more invest.And the capital is put in to professional area.Unstable market and complicated requirements make the manage and operation be difficult.
3.It requires high information technology.Quick transportation and lower cost in transportation are needed.In the process of transportation, safe quality control and track are necessary, due to the asymmetric information.
4.To avoid the agricultural going bad,the higher coordination of organization among every parts.Actually, the benefits of farmer and person should be safeguard. The problems of wasting and unbalanced market force should be solved.
