The mask made of kn95 mask filter membrane has become an efficient medical protective mask due to its efficient filtration performance.
Similar to ordinary medical masks, nano antibacterial masks also include an outer layer, a middle layer, an inner layer, ear hooks, nose clips and other parts.
The special thing about nano masks is that the middle layer is made of nano membrane with smaller pore size (100-200 nanometers), which is generally made of PTFE material.
The kn95 mask filter membrane prepared by one-way or two-way stretching method has a spider web-like microporous structure on the surface. The three-dimensional structure has extraordinary features such as network connectivity, hole nesting, and channel bending. Complex changes, so it has excellent surface filtration function. Nano masks produced using this material have the characteristics of high barrier efficiency, long service life, lightness and breathability, and are a new direction for the development of masks in the future.
? is a high-tech enterprise focusing on R&D, production and sales. We have the characteristics of “uniform and stable, high efficiency and low resistance, long life, customizable, easy cleaning and maintenance” in various fields. , accepted and loved by the majority of enterprises.
