Masks made of ptfe nano mask cloth can be worn all day long, and their filtering performance is not stained It can be used repeatedly without any loss of filtration effect despite the influence of wetness, sweating, humid weather, etc.
The water electret process can ensure that the electret on polypropylene is permanent, the electric field is evenly distributed, and the capture ability is strong. It is currently a relatively mature technology for preparing high-efficiency and low-resistance melt-blown materials. The water electret process can achieve stable N95 material performance at a lower grammage. However, there are not many water electret equipment in China and the production capacity is relatively low. In addition, the operating cost of the equipment is relatively high. Therefore, domestic water electret equipment that meets the performance of N95 is relatively high. Meltblown materials are limited.
PTFE nano mask cloth has good antibacterial and water-repellent properties. Its characteristic is that the human body’s sweat can be emitted outwards, but outside water, bacteria and viruses cannot enter. There are about 1 billion pores per square centimeter, with a porosity of more than 90%. The pore diameter is about 0.2 μm, which is one ten thousandth of the diameter of a water droplet, but about 700 times larger than the size of water vapor molecules. Liquid water cannot enter, and sweat The breath can pass through, thus achieving excellent waterproof and moisture permeability.
The ptfe nano mask cloth produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some masks with a diameter of 0.1um-0.3um For extremely fine particles, the filtration level can reach H13-U16. In addition, the biaxially stretched film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the company’s production process, and it fully complies with current environmental protection standards.
