防毒口罩有多种,通常按其结构与工作原理,分为两大类:空气过滤式口罩与供气式口罩。

There are many types of anti-virus masks, usually divided into two categories according to their structure and working principle: air filter masks and air supply masks.

空气过滤式口罩

Air filter mask

或简称过滤式的口罩的工作原理是使含有害物的空气通过口罩的滤料过滤进化后再被人吸入。一个过滤式口罩的结构分为两大部分,一是面罩的主体,另一个是滤材部分,包括用于防尘的过滤棉以及防毒用的化学过滤盒等。

Or the working principle of the filter mask for short is that the air containing harmful substances is filtered through the filter material of the mask and then inhaled. The structure of a filter mask is divided into two parts, one is the main body of the mask, and the other is the filter material part, including filter cotton for dust prevention and chemical filter box for anti-virus.

 

供气式口罩

Air-supply mask

是指将与有害物隔离的干净气源,通过动力作用如空压机、压缩气瓶装置等,经管及面罩送到人的面部供人呼吸。

It refers to the clean air source isolated from harmful substances, which is sent to the person's face through a tube and a face mask for breathing through a dynamic action such as an air compressor and a compressed gas cylinder device.

采用静电滤材及特效活性炭除异味层,防毒口罩用于颗粒物及有机异味的防护,用于石化、化工、金属冶炼及加工制造业,在一些特种部队中也采用了。高效静电滤材(超越NIOSH要求)呼吸阻力小。特效除异味层,感受新鲜空气。

Using electrostatic filter materials and special activated carbon to remove odor layers, anti-virus masks are used for the protection of particulate matter and organic odors, used in petrochemical, chemical, metal smelting and processing manufacturing industries, and are also used in some special forces. The high-efficiency electrostatic filter material (beyond the requirements of NIOSH) has low respiratory resistance. Special effect deodorization layer, feel the fresh air.
