One of the main ways of transmission of the new coronavirus is droplet transmission. Wearing a mask when going out has become a consensus for everyone to isolate the virus and cut off the spread of the virus. It is also a necessary protective measure.
So what kind of material is the core raw material for making a mask? ptfe reusable mask filter membrane is one of them.
Under the strong call of the country, many factories have taken advantage of the domestic manufacturing industry and quickly purchased mask machines for mask production.
But with the increase in mask machine equipment, another problem faced by the industry is the core filter membrane of traditional masks: melt-blown cloth has become a popular material, and the price of melt-blown cloth materials has also soared, and there has even been a The price is a market phenomenon of more than 500,000 tons.
The ptfe reusable mask filter membrane adopts a special processing technology and is a microporous film made by calendering, extrusion, biaxial stretching and other methods.
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.
