摘要
口罩的性能以及如何选择合适的口罩成为关注的焦点。讨论了8类国内外用于抗击新型冠状病毒的主流口罩,从执行标准出发,着重分析口罩的过滤效率、呼吸阻力、泄漏性、液体阻隔性和微生物指标,旨在了解口罩特性,帮助普通公众和特定行业人员根据使用场景或临床环境选择合适的口罩类型。此外,探讨了口罩的未来研究方向,即制备高效低阻、泄漏率低、液体阻隔性好且可降解回收的口罩。
The performance of face masks and how to choose the right one have become a focus of attention.Eight types of mainstream face masks used in combating COVID-19 at home and abroad are discussed.Based on the standards,the filtration efficiency,respiratory resistance,leakage,liquid barrier and microbial indicators of face masks are analyzed,to fully understand the characteristics of face masks,and help the general public and specific industry personnel to choose the appropriate mask type according to the use scenario or clinical environment.In addition,the future research direction of masks is discussed,that is,the preparation of masks with high efficiency,low resistance,low leakage rate,good liquid barrier and degradable recycling.
