Thin-line nose beam bone is a stainless steel thin line with polyolefin polymer coating. A layer of polyolefin polymer raw material is coated on the hot-dip galvanized thin strip with a diameter of 0.45 mm-0.55 mm At present, most domestic hydrating mask factories choose this kind, which has high output. The manufacturing principle is the same as that of cable and wire production and processing.
Plastic nose bridge strips, all made of polyolefin epoxy resin, have the excellent characteristics of being bent and deformed by external force like iron wire, losing external force and having no resilience, maintaining the existing appearance and being similar to non-woven materials. But at present, the output is low and the cost is much higher than that of composite materials.
The aluminum bridge nose strip is made of metal aluminum alloy plate through stamping die. The advantages of aluminum profiles are excellent bending effect and strong stereotypes. There is hot sol on the reverse side, which can be quickly bonded with the protective cover to improve productivity. The surface layer is smooth, without burrs and rounded corners. Using stamping parts to process, it can be produced in large quantities quickly and the product quality is guaranteed! Safe production! Meet the import and export specifications! The key is to use N95 and kN95 masks.
