1. Appearance of the FFP2 nanofiber air filtration materials of mask
The FFP2 nanofiber air filtration materials of mask have a flat appearance and suitable thickness.
2. Structure of FFP2 nanofiber air filtration materials of mask
The self-developed FFP2 nano-fiber air filtration materials of mask are composed by non-woven fabric protective layer, nano-fiber high-efficient oil adsorption layer (core layer), melt-blown layer and soft surface affinity layer.
3. Property of FFP2 nanofiber air filtration materials of mask
We have the advanced TSI-8130 Automated Filter Tester, which is used to test the filtration efficiency and filtration efficiency of the nanofiber air filtration materials of mask developed by us. It can be seen that the filtration efficiency of FFP2 nanofiber air filtration materials of mask for 0.33 μm oily particles at the flow rate of 95 L/min is over 95%, and the filtration efficiency is below 190 pa (see table below). The high filtration efficiency and low filtration resistance of FFP2 nanofiber air filtration materials of mask are mainly due to the introduction of specific nano-materials, and the technology is in advanced level both at home and abroad. The self-developed FFP2 nanofiber air filtration materials of mask can adsorb and block harmful aerosol, including dust, smoke, fog drop, poisonous gas and poisonous vapor, etc. The self-developed FFP2 nanofiber air filtration materials of mask can meet the European Union 149 standard of FFP2 standard, and can pass the CE certification.
The filtration resistance and filtration efficiency of FFP2 nanofiber air filtration materials of mask (The results were obtained at a flow rate of 95 L/min and oily particles of 0.33 μm)
4. Direction for FFP2 nanofiber air filtration materials of mask
At present, the filtration efficiency of the usual air filtration materials of mask depends mainly on the electrostatic adsorption effect of the melt-blown layer, once put into use, the electrostatic attenuation happens, and it is difficult to be reused. The filtration effect of the FFP2 nanofiber air filtration materials of mask designed by our company mainly depends on the physical interception effect, therefore, it can be reused. The experimental data show that after 10 times of sterilization with boiling water or alcohol, the filtration efficiency kept above 90% at the flow rate of 95 L/min for 0.33 μm oily particles.
Boiling water treatment: The FFP2 nanofiber air filtration materials of mask were immersed in boiling water for 3 minutes, then it is taken out and dried to test the filtration efficiency and filtration resistance.
Alcohol treatment: After the FFP2 nanofiber air filtration materials of mask was sterilized by 75% alcohol spray, and dried, the filtration efficiency and resistance of FFP2 nanofiber air filtration materials of mask were tested.
