PTFE mask membrane captures fine particles

Did you know? The filtration effects of various masks are closely related to the size of the particles they want to filter.

The particles of the new coronavirus that are circulating this time are spherical, and the virus is spread by relying on small particles such as droplets and dust.

In order to block this virus, people usually choose to wear masks made of polytetrafluoroethylene mask film.

Most masks are made of two layers of inner and outer non-woven fabrics, and a middle layer of filter cloth (professionally called melt-blown non-woven fabric).

The filtration principle is: filtering dust mainly relies on the filter cloth in the middle. The main material of melt-blown non-woven fabric is polypropylene, which is an ultra-fine electrostatic fiber cloth that can capture small particles.

When the droplets containing the pneumonia virus come close to the melt-blown non-woven fabric, they will be electrostatically adsorbed on the surface of the non-woven fabric and cannot pass through.

This is how this material isolates germs.

Since fine dust is adsorbed on the filter cloth, and the filter cloth is electrostatically charged and cannot be washed, the masks are disposable.

Nano film masks are new masks with a single layer of nano-polytetrafluoroethylene mask membrane material as the core filter material. They have excellent breathability and protective properties, reflecting the mainstream development direction of masks in the future.

Suzhou New Material Technology Co., Ltd. is a ptfe composite material manufacturer specializing in the research and development and production of polytetrafluoroethylene mask films. After years of painstaking research and research and development, the company not only has strong R&D strength and complete testing methods As well as domestic advanced experimental equipment, it has attracted a large number of outstanding technical talents.
