废旧聚氨酯材料的回收利用研究进展
|
Abstract:
聚氨酯(PU)材料被广泛应用于家居、建筑、航天航空和医疗健康等领域，因此聚氨酯废弃物的数量不断增加。为了更好地理解废旧聚氨酯塑料的回收和降解机理，本文综述了目前常见的回收利用方法，并对这些方法的优缺点进行了讨论。值得一提的是，化学回收法能够高效地实现单体的回收和再利用，不仅减轻了环境压力，还带来了经济效益。
Polyurethane (PU) materials are widely used in fields such as home furnishings, construction, aerospace, and healthcare, which has led to an increasing amount of polyurethane waste. To gain a deeper understanding of the recycling and degradation mechanism of waste polyurethane plastics, this article reviews the commonly used recycling methods and discusses the advantages and disadvantages of various recycling methods. Among them, chemical recovery can efficiently achieve monomer recovery and reuse, truly realizing material recycling, reducing environmental pressure, and bringing economic benefits.
