摘　　要：介绍一种平面型荷电防病毒口罩的结构及基本性能。口罩由过滤层、口罩带及鼻夹组成,过滤层包括保护层、荷电吸附层和致密过滤层。其工作原理是通过正负电荷的相互吸引作用吸附病毒,通过机械截留作用截留微粒。性能检测表明,气流阻力、过滤效率、沾水等级及阻燃性能等性能指标完全符合医用防护口罩技术要求的规定,大肠杆菌噬菌体f2截留率大于99.99%。The structure and performances of the plane-type charge-modified virus-preventive mask are introduced in this paper. The mask is made up of filtering layer, mask belt and nose clip. The filtering layer is composed of protective layer, charge-modified adsorption layer and compact filtering layer. It can absorb viruses by the electrokinetic capture mechanism, and retain particles by the sieving. The test results show that its airflow resistance, filtering efficiency, spray rating and flame retardation conform to the technical requirements of protective mask for medical use. Its retention rate of coliphage f2 is more than 99.99%.
