从化学视角浅谈医用口罩的重复利用

Remark on Reuse of Medical Masks from Chemical Perspective

在认识口罩的分类、防护层组成和结构以及防护原理的基础上,从口罩核心防护层——聚丙烯喷熔无纺布的物理化学性质出发,结合新型冠状病毒的生化特点,浅析一些常用医学消毒与灭菌方法在医用口罩重复利用中应用的可行性。

This paper briefly introduced the classification of disposal face masks,and the composition and structure of key protective layer,in addition to its protection principle.The feasibility of reuse and disinfection of the disposable face masks with several common medical methods is discussed based on the physical structure and chemical composition of meltblown,the main protective layer,in addition to biochemical characteristics of new coronavirus.
