After the waste refrigerator and freezer are disassembled, a large amount of rigid polyurethane foam will be produced. At present, domestic processing of such materials is mainly carried out by incineration and disposal. Incineration of polyurethane foam produces a large amount of smoke and a very pungent odor, which can cause serious pollution to the atmosphere; such as the random disposal of rigid polyurethane foam, because the difficult degradation of such waste plastics will also cause environmental pollution and Waste of resources. The major industrialization project for technological development in Jiangsu Province undertaken by the Institute of Materials Recycling and Utilization, "Research and Application of Waste Household Appliances Recycling Technology and Engineering Application" has made significant progress, using physical methods to recycle and recycle waste polyurethane foam regenerative thermal insulation panels. The new process has also been developed successfully. The new process not only has short processing flow, low cost, and no pollution, and realizes 100% waste resource recycling. The recycled rigid polyurethane foam insulation board products can be applied to building walls, movable board houses, furniture decoration, etc. Fields. This new process has been declared a national invention patent and has been accepted. A Face Shield, an item of personal protective equipment (PPE),
