Filtration efficiency of ptfe reusable mask filter membrane

With the spread of the pneumonia epidemic caused by the new coronavirus, people’s demand for PTFE reusable mask filter materials is growing day by day, because it can effectively block virus intrusion and play a very good protective role. And can be reused.

Medical surgical masks belong to Class II medical devices. They can block blood and body fluids from passing through the mask and prevent the user from being contaminated.

The innermost layer is white, close to the skin, and can absorb the moisture and moisture exhaled by the wearer; the middle layer is a polymer coated by the “spray melting method”, which acts like a barrier to block filtration. The role of germs; the outermost layer is often waterproofed to prevent liquid splashing.

However, medical surgical masks have limited filtration efficiency for particles and are more suitable for suspected cases, public transportation passengers, taxi drivers, sanitation workers, service personnel in public places, etc. to wear during their duties.

The ptfe reusable 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 very complex network connections, hole inlays, and channel bends. 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.

Suzhou New Material Technology Co., Ltd. is a PTFE composite material manufacturer focusing on the research, development and production of PTFE reusable mask filters. After years of painstaking research and development, the company not only has strong R&D strength and complete testing Means and domestically advanced experimental equipment have attracted a large number of outstanding technical talents.
