聚氨酯硬质泡沫塑料的回收处理

Recycling of PU Rigid Foam

聚氨酯硬质泡沫塑料是一种性能优良的绝热材料和结构材料。在聚氨酯各类制品中,产量仅次于软质泡沫塑料。应用于冷冻冷藏设备、汽车、火车、屋顶、硬泡空心砖、聚氨酯硬泡混凝土、贮罐管道绝热、包装、办公用品等领域。由于广泛的使用也导致了大量废弃物的出现(废料与边角料),污染了环境,因此对聚氨酯硬泡的回收和处理成为迫切需要解决的问题。

Polyurethane rigid foam, a kind of high performance materials for thermal insulation and building, is widely applied in fields such as refrigeration and freezing, automobiles, trains, roofs, hollow bricks, concrete, storage pipes, packaging and office appliances. On the other hand, however, large quantities of wastes come up during their frequent uses, which poses threats to the environment and makes the recycling of this material an issue needed to be addressed right away.
