摘要
2020年新冠疫情爆发以来,口罩成为大众防护病毒的首选防疫产品,出门戴口罩,也成为人们的日常习惯。口罩产品形式多样,其中平面口罩的销售量和使用量最高,但其整体防护效果也引起了不少争议。本文通过对平面口罩的滤过效率、泄漏性和呼吸阻力的技术性能进行测试,综合评估该产品的整体防护效果。
Since the CoVID-19 outbreak in 2020,masks have become the first choice for the public to protect themselves from the virus.Wearing masks outdoors has become a daily habit for people.Masks come in a variety of forms,among which flat masks are the most widely sold and used,but their overall protective effect has also caused a lot of controversy.In this paper,the filter efficiency,leakage and respiratory resistance of the planar mask were tested to comprehensively evaluate the overall protective effect of the product.
