The nose bar is an important component of the mask. Today, I want you to know its function, material and selection.
Nose bar is also called nose bar, nose line, iron core nose bar (single core nose bar, double core nose bar), full-plastic nose bar, and shaped bar. It is a hard strip inside the mask, which plays the role of fixing the mask on the nose bridge, supporting the mask, and increasing the fit between the mask and the nose frame.
There are usually three types of nose bridge strips:
1. Iron core nose bar: It is composed of PP (polypropylene) and iron wire, which can be divided into single core and double core.
2. All-plastic nose bar: made of PE (polyethylene).
3. Aluminum nose bar: made of aluminum after processing.
The nose bar is mainly used for medical masks, disposable masks, dust masks and non-woven masks.
What is the difference between single-core nose bar and double-core nose bar? Generally speaking, in addition to the difference in price and manufacturing process, the characteristics of the products will also be different. The masks with different requirements usually choose different sizes and single-core and double-core nose bars.
Double-core technology will be used for the nose bar with a diameter of more than 5mm. Because the material is too wide, if a single core is used, the material cannot have a good shaping effect. In the same specification, the shaping effect of the double-core is better than that of the single core, and the price is also higher than that of the single core. Generally, according to different uses, the 3mm single-core nose bar can also meet the general use of the mask, and can also play a good shaping effect, so select the appropriate nose bar
