细颗粒物(PM2.5)过滤口罩专利技术综述

Analysis of Mask Technology for PM2.5 from Patent Perspective

近年来我国多地出现严重雾霾天气,雾霾的主要原因之一是细颗粒物(PM2.5)浓度的急剧增长,严重影响了人民身体健康、城市形象,人才吸引,如何有效防治PM2.5的污染,是所有人都关心的一个社会环境问题。文章从专利技术角度解析防治PM2.5最常用的呼吸过滤装置如口罩,其主要技术手段在于过滤层结构设计,过滤材料选择及其它电、磁、化学手段的综合运用,有利于相关领域人员对于过滤口罩技术的全面了解及正确防护。

In recent years, the severe hazes attack most of developed area of China, especially in the capital of Beijing. Haze is caused by fine particulate matter （PM2.5） concentrations of rapid growth, which serious impact on people＇s health, the city＇s image, talent attraction. How to effectively control PM2.5 contamination is a problem to the government and citizens. The article is about controlling PM2.5 by mask filter from the patent perspective. Main technical means are filter materials and mask structure designing and additional with electrickmagnetic device. Through the above analysis, we have a basic knowledge of the PM2.5 mask technology and active protecting method.
