The application of FRP sheets on refrigerated trucks is an important technical choice for modern cold chain logistics and transportation, and has excellent performance in many aspects. TOGLOSS provides you with the best choice of FRP sheets.
Material structure and process
The FRP sheets of refrigerated trucks adopt a sandwich composite structure. The inner and outer skins are made of FRP sheets, and the middle layer is made of high-strength mesh cloth and high-density polyurethane foam. It is made through vacuum and high-pressure composite processes. This structure ensures the light weight, high strength and excellent thermal insulation performance of the Sheet.
Key performance advantages
1. Excellent thermal insulation performance
The thermal conductivity of FRP is only 1/100-1/1000 of metal, and the thermal conductivity at room temperature is 1.25~1.67kJ/(m·h·K). It is an excellent thermal insulation material. The interior of the composite panel is seamless, dense and non-deformable, which can effectively maintain a stable temperature inside the cabin and reduce the operating time of the refrigeration unit.
2. Lightweight and high-strength properties
The density of FRP is only 1/4-1/6 of steel, but its mechanical strength is close to or exceeds that of carbon steel. Compared with traditional steel and aluminum frames, fiberglass refrigerated truck composite panels can reduce weight by 30%-40%, significantly reducing vehicle weight and improving transportation efficiency.
3. Excellent corrosion resistance
FRP has good chemical stability to the atmosphere, water, acids, alkalis, salts and other media of general concentration, and will never rust. The surface has been treated with colored gelcoat, which can remain smooth and non-discolored for a long time, and is especially suitable for high salt spray environments in coastal areas.
4. Easy to clean and maintain
The surface of FRP is smooth and clean, dirt can be easily washed away, and it meets the hygienic requirements for food transportation. At the same time, it has good repairability and can be repaired seamlessly after damage. There are basically no traces after repair.
5. Good sealing and waterproofing
Rigid polyurethane foam has a large closed cell ratio and excellent water resistance. The FRP sheets itself is impermeable, and the seam-free and rivet-free design ensures the anti-seepage and leak-proof performance of the carriage.
Application specifications and scope
The fiberglass refrigerated truck composite panel can be up to 13.5 meters long, 2.9 meters wide, and generally 50-120 mm thick. Different specifications can be customized according to user needs. It is widely used in various cold chain transportation scenarios such as vaccine refrigerated trucks, meat hook refrigerated trucks, fruit and vegetable refrigerated trucks, and dairy refrigerated trucks.
economic advantage
Compared with stainless steel, aluminum alloy and other materials, fiberglass refrigerated trucks have more advantages in price, low maintenance costs, no need for regular repainting, no surface maintenance costs, and high cost performance.
The application of FRP sheets on refrigerated trucks not only improves the insulation performance and durability of the vehicle, but also reduces operating costs. TOGLOSS's FRP sheets make it an ideal choice for modern cold chain logistics transportation.
