废旧口罩循环回用技术研究进展

Research Progress in the Recycling Technology of Waste Masks

废旧口罩会对环境造成严重污染,且大多数一次性医用口罩主要由防水层、过滤层、耳带和鼻梁条等部件组成,组成成分复杂,回收利用有一定困难。针对废旧口罩的循环利用,文中综述了废旧口罩的回收消毒、物理回用、化学回用技术,详细阐述了废旧口罩在土木工程、油水分离材料、炭化材料、降黏剂、传感器、阻燃塑胶弹性体等领域的应用研究进展。

Waste face masks can cause serious pollution to the environment,and most disposable medical masks are mainly composed of components such as waterproof layer,filter layer,ear band,and nose bridge strip,which are complex in composition with certain difficulties in recycling.In response to the recycling of waste masks,this article reviews the research progress in the recycling and disinfection,physical recycling technology,and chemical recycling technology of waste masks,and elaborates the application progress in the field of civil engineering,chemically modified carbonization technology,viscosity reducers,sensors,and plastic elastomers.
