Problems solved by technology

At present, the nose bridge strips used for masks mainly include the following types: (1) polyolefin polymer material coated galvanized fine iron wire; (2) metal aluminum sheet; (3) all-plastic nose bridge strips, wherein the metal aluminum sheet has Good bending and shaping characteristics, but this kind of metal nose bridge is not conducive to the separation and recycling of waste masks; polyolefin polymer material coated galvanized thin iron wire is a material widely used by most mask manufacturers at present, and its processing principle Similar to wires and cables, polyolefin polymer materials are used to coat galvanized thin iron wires with a diameter of 0.45-0.55mm. Molecular materials are difficult to separate, which is not conducive to the separation and recycling of waste masks; while the all-plastic nose strip is mainly made of a single modified polypropylene or modified polyethylene material, which is more and more popular because it is conducive to the separation and recycling of masks. At present, there are still problems such as the all-plastic nose strips are not easy to compress, and the shaping effect is not ideal.
