Closeness
Air is like water flow, where the resistance is small, it flows
first. When the shape of the mask is not close to the human face,
dangerous substances in the air will leak from the close to the
human's respiratory tract. Well, even if you choose a filter with
the best mask. Nor can it protect your health. Many foreign
regulations and standards stipulate that workers should regularly
perform mask tightness tests. The purpose is to ensure that workers
choose the correct size mask and wear it in the correct steps.
A face mask is a sanitary product, generally refers to a device
worn on the nose and nose to filter the air entering the nose and
nose to prevent harmful gases, odors, and droplets from entering
and exiting the wearer's nose and nose, made of gauze or paper.
Masks have a certain filtering effect on the air entering the
lungs. When respiratory infections are prevalent, wearing masks has
a very good effect when working in a polluted environment such as
dust.
parameter of disposable surgical masks
- Provide respiratory protection for the wearer against certain
airborne particles.
- Reduces exposure to harmful airborne particles which are small
enough to be inhaled – typically particles less than 100 microns in
size (Bacillus anthracis, Mycobacterium tuberculosis, mould and the
virus that causes Severe Acute Respiratory Syndrome (SARS), and
Influenza)

construction of disposable surgical masks
Compared with traditional meltblown masks
1. The filtration efficiency of PTFE for air bacteria and PM2.5
particles can reach more than 95%, which meets the filtration
standards of KN95 masks.
2. PTFE membrane is naturally hydrophobic. The filtering mechanism
is physical mechanical retention (pore size interception method),
which will not reduce the retention rate due to exhaled moisture,
which is more stable and durable than the electrostatic adsorption
protection of ordinary meltblown cloth masks.
Features of disposable surgical masks
The core material of the film mask is a PTFE nano film, and the
diameter of the film fiber is between 100 and 200 nanometers.
The film mask made of this material has the following three
characteristics:
1. Higher blocking efficiency. The main reason is that the fiber
diameter of the material used is smaller than that of traditional
materials (the fiber diameter of non-woven materials used in
traditional masks is more than 1000 nanometers), which can more
effectively block PM2.5 in the air (aerodynamic equivalent diameter
is 2500 nanometers or less Particulate matter), and effectively
reduce the concentration of bacteria and viruses in the air;
2. Longer life. The reason is that it uses physical principles to
isolate air pollutants and is more durable. (The non-woven fabric
used in traditional masks has a large fiber diameter and needs to
rely on electrostatic adsorption of particulate matter. Static
electricity is affected by temperature and humidity in the
environment in a short time. Invalid, so it can only be used once);
3. Breathe more easily and freely when worn. The wearing comfort of
the mask is mainly determined by the breathability and moisture
permeability of the mask. The film mask has a higher air
permeability due to its material characteristics of a high uniform
hole distribution rate; coupled with the moisture-proof and
moisture-permeable characteristics of the film material, it can
bring users a more comfortable breathing experience.
