Barrier properties of PTFE mask cloth
Polytetrafluoroethylene mask cloth is obtained by compounding ptfe microporous membrane and non-woven fabric. The fiber diameter is less than one hundred nanometers and relies on pure physical filtration. It can well block viruses and PM2.5 particles in the air. The mesh structure of the staggered nanofibers has good filtration efficiency and has the characteristics of high filtration efficiency and low resistance. Mask filter materials with two-layer and three-layer structures are available, which are similar to the common two-layer structure. They are efficient and easy to process. It is a new material for high-quality masks. This material is a microporous film formed by expanded and stretched polytetrafluoroethylene resin. The average pore size can reach nanometer level.
Andpolytetrafluoroethylene mask cloth uses purely physical filtration. Unlike the static electricity of melt-blown materials that will dissipate over time, ptfe nanomaterials can be stored for a long time. The fiber cross-sectional area of ptfe nanomaterials is only 1% of that of pp meltblown fibers. The fibers are interlaced to form a polytetrafluoroethylene mask cloth environmentally friendly material manufacturer that specializes in R&D, production and sales. Our company is different from other manufacturers. Our company can according to the user’s requirements. By optimizing the key technical parameters of speed ratio, pressure ratio, operating temperature and other parameters, online control of air permeability, thickness and void ratio can be achieved based on the ratio and pore-forming medium to meet your different requirements. Interested parties can enter the store for consultation. The mesh structure has very good filtration efficiency.
