随着科技进步和产品更新换代速度的加快，废旧冰箱的数量逐渐增加。冰箱拆解后产生的大量聚氨酯泡沫由于含有大量的氟氯化碳而难以降解。如何有效地处理和处置聚氨酯泡沫塑料已成为全球关注的问题。而在中国，产生的聚氨酯泡沫通常是填埋或焚烧，而不是综合利用。本文在对聚氨酯泡沫的产生和处理技术进行调查的基础上，对热回收法、物理法、化学法、生物法和热解法五种不同类型的处理技术进行了比较，分析了它们的经济性和实用性。同时，结合国家相关政策要求，分析了聚氨酯泡沫管理面临的主要问题，并提出了具体建议。
The amount of waste refrigerators has been increased gradually with the scientific and technological progress and accelerated rate of replacement products.A large amount of polyurethane foam generated form dismantling of refrigerators,are difficult to be degraded owing to many CFCs containing.How to effectively treat and dispose the polyurethane foam has become the global concern.While in China,the polyurethane foam generated are usually landfilled or incinerated rather than comprehensively utilized.Based on investigation for the amount of polyurethane foam generation and disposal techniques,this paper has made a comparison of five different types of treatment technologies,including thermal recovery method,physical method,chemical method,biological method and pyrolysis method,and analyzed their economy and practicability.Meanwhile,combined with the relevant state policy requirements,the paper analyzed main problems faced by the management on polyurethane foam and provides specific suggestions.
