Masks are a common item in life. Wearing them correctly can not only keep warm, but also have a good protective effect. The filter materials for masks are generally melt-blown cloth, and PTFE membrane materials are also used.
First of all, meltblown cloth is a filter material made of polypropylene as the main raw material. The fiber diameter can reach 0.5-10 microns. These Very thin fibers with special capillary structure increase the number and surface area of fibers per unit area, making the meltblown cloth have good air filtration properties and is a relatively good mask material.
The nano film mask is a new type of mask that uses a single layer of nanoptfe nano film material as the core filter material, and has excellent breathability Performance and protective properties also reflect the future development direction of masks. Qualified film masks can not only effectively block PM2.5 particles in the air, but also significantly reduce the concentration of viruses, small bacteria, etc.
Traditional non-woven masks are processed through the electret process, resulting in an electrostatic effect that intercepts particulate matter. . However, as the moisture brought by breathing changes during use, its filtration efficiency will decrease and it needs to be replaced every four hours. Moreover, the adsorbed particulate matter can easily lead to a decrease in breathability and reduce wearing comfort; film masks using ptfe nanofilm material have small fiber diameters, high dust blocking efficiency, and rely on physical effects to intercept particulate matter. , its interception of 0.3 micron particles can reach more than 99.5%, and it can be reused multiple times after simple high-temperature water treatment, alcohol spraying, and more. In addition, the comfort level of wearing a mask is mainly determined by the breathability and moisture permeability of the mask. Film masks have higher air permeability due to their material characteristics of high uniform distribution of holes; coupled with the moisture-proof and moisture-permeable characteristics of the PTFE film material itself, it can give users a more comfortable breathing experience.
ptfe nanofilm technology has always been the core of business, in biopharmaceuticals, equipment, food and beverages, semiconductor processes, communications, etc. It plays a very important role in many fields. Its pore-forming capacity ranges from 0.1μm to 1μm, providing functional solutions such as fine filtration, removal of small bacteria and viruses, hydrophobic breathability, and sound transmission.
