respirador com peça facial filtrante tendo uma malha auxética no corpo da máscara |
摘要 |
A filtering face-piece respirator 10 that has a harness 14 and a mask body 12. The mask body 12 includes a support structure 16 and a filtering structure 18. The support structure 16 contains an auxetic mesh 20 that has been molded into an intended cup-shape configuration, and the filtering structure 18 contains a filtration layer 42 for removing contaminants from the ambient air. The use of an auxetic mesh 20 in the support structure 16 provides more uniformly-sized openings 26 in the mesh 20 and reduces opportunities for mesh overlapping and mesh distortion. |
