1.Appearance of the KN90 nanofiber air filtration materials of mask
The KN90 nanofiber air filtration materials of mask of mask have a flat appearance and suitable thickness.
2.Structure of KN90 nanofiber air filtration materials of mask
The KN90 nanofiber air filtration materials of mask were composed by non-woven fabric protective layer, nanofiber high-efficiency filter layer, melt-blown layer and skin-friendly non-woven fabric layer.
3.Property of KN90 nanofiber air filtration materials of mask
The KN90 nanofiber air filtration materials of mask have a filtration efficiency of more than 90% for 0.3 μm non-oily particles at a flow rate of 85 L/min (see the table below), which can effectively intercept fine particles such as droplets, PM 2.5, dust and pollen. The KN90 mask made by KN90 air filtration materials of mask is mainly applicable to industries that produce micron-sized dust, smoke, fog and other particulate pollutants from non-ferrous metal processing, metallurgy, steel, coking, gas, organic chemicals, food processing, construction, decoration, petrochemical and asphalt.
The filtration resistance and filtration efficiency of KN90 nanofiber air filtration materials of mask (the results were obtained at a flow rate of 85 L/min and non-oily particles of 0.3 μm)
4.Direction for KN90 nanofiber air filtration materials of mask
The filtering effect of the nanofiber air filtration materials of mask developed by our company mainly depends on the physical interception effect of the nano-fiber layer, so the nanofiber filter materials can be reused. Experimental data show that after 10 times of disinfection with boiling water or alcohol, the filtration efficiency of the nano-fiber filter materials for non-oily particles with a diameter of 0.3 μm can still be kept above 80% at a flow rate of 85 L/min, which can meet the protection requirements of the air filtration materials of mask.
5.Test report of KN90 nanofiber air filtration materials of mask
The nanofiber air filtration materials of mask manufactured by our company satisfy the KN90 protection standard. The results were obtained from Henan Medical Device Inspection Institute.
