Mask
is a kind of sanitary product, which is generally used to filter the air
entering the mouth and nose by wearing it on the mouth and nose, so as to block
harmful gases, smells and droplets from entering and leaving the mouth and nose
of the wearer.
Masks
generally use physical electrostatic adsorption technology to filter solid
particles, but electrostatic adsorption masks have a disadvantage: when static
electricity is added, it is not always saturated. In every link of mask
production, packaging, delivery, transportation, and opening to consumers, the
electrostatic content in the non-woven fabric layer will gradually reduce, and
the electrostatic attenuation is inevitable , therefore, it can only
be used once.
Recently,
the Chinese society of composite materials proposed a new development direction
of epidemic prevention - Nano masks. Nano mask has become an effective medical
protective mask due to its high filtering performance. Similar to traditional
medical masks, nano masks also include outer layer, middle layer, inner layer,
ear hook, nose clip and other parts. The special feature of the nano mask is
that the middle layer is made up of nano film with smaller aperture
(100-200nm), which is generally made up of PTFE film.
