I never thought that an inconspicuous little mask would be closely related to the life and safety of each of us during the Spring Festival of 2020.
Since the outbreak of the new coronavirus pneumonia, “mask” has become one of the hottest words in 2020.
The ptfe medical mask filter material we are going to introduce today is one of the raw materials for making masks.
Fiber filtration consists of five mechanisms (interception effect, inertia effect, diffusion effect, electrostatic effect, and gravity effect).
For particles below 0.5μm, the filtration effect is highly related to the electrostatic effect.
The electrostatic filtration effect of melt-blown cloth can be effectively improved through electret treatment or electret modification.
The size of the new coronavirus is 0.1μm.
Although Academician Zhong Nanshan said that virus-containing particles transmitted by droplets are basically at the PM4 level, for medical staff with high risk of exposure, the risk of aerosol transmission is very high.
Masks can filter viruses, mainly from the key material – ptfe medical mask filter material.
The material is polytetrafluoroethylene, which is made of extremely fine interwoven fibers. The average diameter of the fibers is about 2 μm. The material has been treated with stationary surface to make it electrostatically charged to enhance the adsorption capacity of dust and particulate matter.
It is a high-tech enterprise focusing on the research and development, production and sales of ptfe medical mask filter materials. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we produce The products are produced using imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
