With the increase of global epidemic data, the use of masks is increasing; Lead to tight supply. In order to solve the problem of mask demand, many enterprises have also started to produce masks, and nose strips as mask accessories are no exception. The role of the bridge of the nose is to make the mask fit the face better and ensure that bacteria are not easy to enter the respiratory tract. The nose bridge strip needs to have a good stressed shape, which will not rebound when it is not stressed, and the existing shape will not be deformed.
There are three kinds of materials commonly used to make nose bridge strips: thin galvanized steel wire coated with polyolefin polymer, plastic and pure aluminum.
The iron wire nose bridge is a thin galvanized steel wire coated with polyolefin polymer, and a layer of polyolefin polymer material is coated on the thin galvanized steel wire with a diameter of 0.45 mm-0.55 mm At present, most mask factories in China adopt this type, with high productivity. The manufacturing principle is the same as wire and cable processing.
Plastic nose bridge strips are all made of polyolefin resin. Like metal wires, they bend and deform with the external force, and do not rebound when the external force is lost, keeping the existing shape unchanged. They can be similar to nonwoven materials. But at present, the production capacity is low and the cost is much higher than that of synthetic materials.
Aluminum nose bridge strips are stamped from metal aluminum plates. The advantages of aluminum material are good bending effect and strong plasticity. With hot melt adhesive on the back, it can be quickly bonded with the mask to improve production efficiency. Smooth surface, no burr and smooth ellipse angle. Using stamping processing, it can be produced in large quantities and quickly, and the product quality is guaranteed! Safety and environmental protection! Meet export standards! Mainly used for N95 and kN95 masks.
