4 Layers Disposable KN95 Face Mask With Antibacterial And Antiviral
Fibres
Antiviral mechanism of silver:
Silver is a typical metal material, It has a large specific surface
area and the particle
size is very small. The percentage of surface atoms increased make
amount of surface
atoms increased, there are no adjacent atoms around to lead many
unsaturated
bonds, which have unstable atoms with high surface energy. This
structure provides
many contact adsorption sites and reaction points in various
reactions. It is easy to
bond with foreign atoms by chemical bonds, which increases ability
of absorbing
viruses and strengthens chemical reaction capacity among viruses
mutually.
the following information:
1. Silver has mechanical adsorption and fixation of the virus. The
surface of the
metal ultramicro particles is covered by a layer of polymer which
is 5 to 10
meters thick. It can immobilize a large number of proteins and
enzymes,
especially polysaccharides. Many polysaccharides may block the
adsorption of
viruses to host cells, showing strong antiviral activity.
Meanwhile, due to the
colloidal stability and strong adsorption of metal particles, the
virus lost its
survival conditions and died.
2. Silver prevents the virus from entering the host cell, and
inhibits its binding to the
cell receptor, and thus prevents the virus from infecting the host
cell. Some small
metal molecules can bind to the conserved spatial structure of the
surface
protein of the virus to inhibit the interaction between the virus
and the receptor.
It can prevent the virus from entering the cell and directly
inactivate the virus,
which may be similar to killing bacteria. For example, the silver
particle combines
with -- SH of the surface protein of the virion to form -- SAg
complex, which
inactivates the enzyme protein, interferes with the entry of the
virus into the cell
or kills the virus, leading to the inactivation of the virus.
Advantage of Titanium:
1. No skin irritation.
2. Strong antibacterial ability, wide antibacterial range.
3. Good thermal stability, it does not change color, decompose,
volatilize and
metamorphism under high temperature.
4. Good immediacy, only 1 hour to show the effect.
5. TiO2 is a persistent antibacterial agent.
6. Effective antibacterial function can remain 4 days (assuming 8
hours usage per day).
