Expanded polystyrene is a packaging material, such as televisions, refrigerators, washing machines, air conditioners, electronic instruments, precision instruments, glassware, ceramic products, handicrafts, and other products. It cannot be separated from expanded polystyrene as a buffer packaging. Polystyrene foamed plastic is a lightweight material made by heating and foaming polystyrene resin as the base material, adding foaming agent and other auxiliary materials. It has the advantages of light weight, low thermal conductivity, low water absorption, water resistance, aging resistance, low temperature resistance, easy processing, low price, and high quality. It's seafood freezing, vegetable preservationInsulation boxContainers of indispensable insulation and preservation materials for cold storage, refrigerated vehicles, railway passenger cars, etc. Expanded polystyrene packaging is easy to recycle and reuse, making it a good green packaging material. Before use, simply put the ice bag in the refrigerator into a household refrigerator to fully freeze, and then refrigerate it in a passive car refrigerator. It is very convenient to use and can generally be kept at a low temperature for more than 72 hours. In winter, if the ice bag is fully heated in a microwave and then placed in a passive car refrigerator, it can also serve as insulation. The present invention avoids the noise generated during the operation of the compressor and has the characteristics of semiconductor refrigerators, such as energy conservation, environmental protection, noise free, lightweight, and flexibility. It is expected to occupy a place in the automotive refrigerator market.
