Structural analysis of medical flat masks

1. PP non-woven fabric,

2. Melt blown cloth,

3. The bridge of the nose,

4. Ear straps and other materials.

Medical flat face masks are divided into three layers: inner, middle and outer. The inner layer is made of skin-friendly material, the middle layer is an isolation filter layer (usually melt blown cloth), and the outer layer is a special material antibacterial layer.

Why can meltblown cloth filter?

1. The meltblown cloth is polypropylene PP, the fiber diameter is 1-5um, which is similar to the size of bacteria/droplets/droplet cores

2. A layer of melt blown cloth can effectively filter bacteria/droplets (3um), and the three-layer melt blown cloth represented by N95 can effectively filter small particles (0.3um)

3. The production capacity of masks in my country accounts for half of the world, with a daily output of more than 20 million, but only 54% for medical use. Due to various reasons of processing technology and certification, the output of industrial grade N95 is very small, about 1/100 of that of medical use, and most of the rest are It is the fake "civilian" mentioned by the governor of Hubei-a truly non-standard disposable ordinary flat mask. At present, industrial and three types of medical flat masks are all in urgent need, and they are given priority to medical staff. The market is also full of non-standard masks. We can identify and purchase ordinary masks that meet the requirements of anti-droplet through keywords such as melt blown cloth. .
