What is the protective performance of the PTFE filter material of children’s masks?
The dust layer formed by the ptfe filter material of children’s masks is easy to crack and rot, and the filter material has good air permeability. Since the coated filter material relies on a thin film to capture dust particles, the dust layer can only form on the outside of the filter material film, and the film is hydrophobic The adhesion between the dust layer and the filter material is small and easy to separate. It can fall off by its own weight without external force.
If the dust is blown back, it can be completely removed. If anti-static PTFE high-temperature film is used, the dust can be stripped off more easily and the dust can be cleaned more thoroughly.
