N95 mask is one main kind of the masks with the largest medical demand abroad. The filtering efficiency of this masks to non-oily particles (such as dust, acid mist, paint mist, microorganisms, etc.) can reach 99.5%.
In addition to the 95% filtration efficiency, an important factor for N95 masks is the close fit of the mask to the face, which is why we need aluminum nose strips for masks. To ensure the good combination of aluminum strip with the masks, there are special requirements for aluminum strip for mask and glue.
The aluminum strip for face mask is usually made of 1060 and 3003 aluminum strip. It should have good stamping performance and good ability to withstand various pressure processing and stretching.
It must be of bright surface, good straightness, no deformation, stable size, high strength and good toughness. Haomei aluminum strip has good adhesion with various kinds of glue. There are generally two kinds of glues: hot melt adhesive and double-sided adhesive. The aluminum mask strips with hot melt adhesive on the back will be more effective when it is attached to the mask.
One of the equipment required for the production of masks is the aluminum nose wire welding machine. This equipment uses the pneumatic principle and realize the combination of aluminum nose strip and masks. Finally, a medical mask with good protective performance is finished.
