Refrigerator van box Environmental protection properties: There is no volatile and corrodible substance on surface of fiberglass. Refrigerator van box New type FRP was used as outer skin of roof, wall and door. The panel used for the van was constructed in type of sandwich. The middle layer of the sandwich is a kind of new type fluorine-free polyurethane /Extruded polystyrene foam. The sandwich panel is fixed to the steel frame with high strength adhesive and screws. The thermal insulation layer is 50-80mm thick, which offers a very good thermal insulation performance. The van body is tight and solid with a very high mechanical strength, smooth and nice appearance, anti-corrosion, shock-proof, standing wear and easy to be washed. The van is built in a full close steel frame structure. All panels are adhered with high strength structural adhesive to achieve the most reliable conjunction, sealing and insulation properties. This structure is also easy and fast to be assembled. The door panel is produced by a high accuracy process with imported sealing rubber to keep good airtight and thermal insulation. The inside and outside of the van are decorated with special aluminum alloy profiles or stainless steel edge, aluminum angle, FRP corner, and galvanized hinge. There are protection guardrails in both sides and end of the van. Various lights are installed as well. The whole body is beautiful, harmony, strong, liable and durable. (1) Reinforced floor design adopts high quality figured aluminum floor panel to ensure the loading capacity, strong and wearing resistant as well as easy to load or unload. (2) The van can be designed according to customers requirement to select material and design the structure as well as to install refrigerators. Main properties; ·Light in weight: 30-40% lighter than domestic traditional products. ·Thermal insulation properties: The coefficient of heat conductivity of fiberglass reinforced plastics face panel is about 0.20W/M2.K, the coefficient of heat conductivity of hard polyurethane foam is 0.018-0.028W/M2.K, and the K #118alue of overall coefficient of heat transference can be below 0.30W/M2.K. ·Surface properties: Surface of fiberglass reinforced plastics panel possesses very high tensile strength, bending strength and impact ductility. It also possesses excellent chemical stability against rainwater, acid and alkali with low PH #118alue. Therefore, its surface is very smooth, unfading, anti-ultraviolet radiation and easy clearance. Particularly, it is suitable to be used for various carriage advertisements. ·Impermeability properties: Both sides of FRP panel possess excellent water impermeability and water resistance. ·Fire retardant performance: It conforms to the national standard B1 level. ·Service life: 4-6 times longer than domestic traditional products. ·Easy maintainability: There is no trace on the panel after repair, which is more competitive than steel and aluminum panels. ·Environmental protection properties: There is no volatile and corrodible substance on surface of fiberglass reinforced plastics. The panels are sandwiched with polyester foam plastic without fluorine. It is green environmental protection product
