With the arrival of the new virus, “mask” has become a hot search term.
We all know that a mask is a sanitary product, which generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose to prevent harmful gases, odors, and droplets from entering and exiting the wearer’s mouth and nose.
Today, in order to better block the virus, people will use ptfe mask cloth.
First of all, let’s talk about what the letters in front of the mask mean. N means the American standard NOISH, FFP means the European standard EN149, and KN means China’s own standard GB2626-2006.
And if there is a V at the end, it means there is a valve.
As for the function of the valve, it is mainly used to prevent dust. In fact, it has no effect on preventing the inhalation of viruses.
PTFE mask cloth is a microporous film made by calendering, extrusion, biaxial stretching and other methods using a special processing technology.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
Three-dimensional mesh structure, no through holes.
The porosity and pore size distribution are important indicators for measuring films.
The porosity of the film is generally between 80% and 95%. A high porosity will increase the ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
It is a ptfe mask cloth manufacturer specializing in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
