聚氨酯泡沫在环境领域的应用及其回收处理

摘要

总结了聚氨酯泡沫在环境领域的应用开发,包括利用聚氨酯泡沫作为水处理金属离子吸附剂、气固废吸附材料基材、废水处理用微生物载体.综述了废旧聚氨酯泡沫回收处理及利用方法,重点阐述了物理回收法、化学回收法中的醇解、水解、氨解、热解法等.最后对各类回收方法进行了总结比较.%The application and development of polyurethane foams in the environmental field, including the use of polyurethane foam as metal ion adsorbent for water treatment, gas and solid waste absorbent substrate, micro-carrier for waste water treatment, were summarized. The waste recycling and reuse methods of polyurethane foam were reviewed, focusing on the physical recycling and chemical recycling methods, such as alcoholysis, hydrolysis, am-monolysis, pyrolysis, etc. Finally, various types of rcycling methods were concluded and compared.
