With the large-scale outbreak of coronavirus, one of the issues that everyone is most concerned about now is the issue of mask protection.
So which masks have a protective effect on this new coronavirus? The answer is medical surgical masks and N95 masks, and the production of these two masks requires the use of kn95 mask filter membrane materials.
The ?kn95 mask filter membrane filter material 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.
It is a filter material manufacturer specializing in R&D, production and sales.
