Our country has just experienced an epidemic this year. We ordinary people cannot go to the front line to fight the epidemic like the medical staff, soldiers and volunteers, but we can avoid causing trouble to the anti-epidemic personnel and minimize going out. Even if you go out, don’t go to crowded areas. When you go out, you should disinfect it first and then wear a mask when you go out. Keep a safe distance from pedestrians. When you go home, you should disinfect it first, and then dispose of the used mask. This is what we did during the epidemic. Masks have become a necessity in our lives, and we will not go out without disposable masks.
The disposable masks we use are all processed and made by mask manufacturers. Although some unscrupulous traders in the market raise the price of masks, and some will sell some inferior masks, we believe that the country can carry out Punishment, in this process we know what the materials of disposable masks are.
One is the gauze mask, which was used by medical staff when the epidemic occurred in the past. This structure does not fit well with the human face and is not tight enough. Many small particles can enter the human respiratory system through the gaps. If this kind of fabric wants to improve the barrier efficiency, it must increase the thickness, but this will hinder the human body's breathing. The medical staff at that time defeated the epidemic in this environment.
There is also a non-woven mask, which is also widely used now. The layer of this mask can block large particles of dust, and then can absorb small particles of dust through electrostatic effect, and the filter layer in the middle can also filter out Most particles, and the fabric is thin enough to not hinder breathing.
